Solar Powered Heat Lamps? Best 51 Answer

A:

Basically yes, you can run heat lamps or most other heating devices on the DC voltage provided by batteries. However, batteries do not store very much energy. A fairly large 12V car battery can have a capacity of around 200 amp hours, which means only around 2.4 kWh of energy. A typical electric heater uses over a kW of power, so you can only run it for 2 hours on a battery. I think if you buy 10 large car batteries you could run for about a day and the 120v you would get if you put them in series would be just what a standard heater would need. Somehow that just doesn’t sound practical. There are alternatives. You could get a propane heater as long as you take care to vent it safely etc. There is a lot of energy in a propane tank. Or if you are more comfortable with just electric power inside, you can use a gas powered generator just outside the barn. Again, a gas tank holds a lot of energy. Perhaps you could use a charge of solar panels to recharge the batteries on sunny days. If you felt like doing it (probably not practical either), you could use a heat pump (a reverse air conditioner) to pump in about five times as much energy as you’re using from your battery. That could also require an inverter to convert battery power to AC power. You probably don’t want to do what my roommates and I did in grad school — keep the goat in the house. It was ok with one goat (she was the most stable member of our group) but it could get awkward with more than one. So you have many options, but they are all a bit cumbersome and/or expensive.

Heat lamps are incandescent lamps whose main purpose is to provide a focused source of heat, although they also provide light. Heat lamps are most commonly used in places like showers and bathrooms, which are often the coldest places in the house — especially in winter. Your advantage in these rooms is that they provide radiant heat quickly and are relatively economical to use for a short time. Likewise, they are often incorporated into watertight units that also include an exhaust fan.

Heat lamps are often built into exhaust fans.

How do heat lamps work?

Conventional light bulbs work by heating the tungsten filament inside the bulb so much that it produces visible light energy. Heat lamp bulbs, on the other hand, have optimized filaments (usually quartz) that resist electricity, resulting in the production of excessive amounts of infrared radiation that directly heats the human body. Heat lamps usually contain internal reflectors designed to focus the light and heat directly on a specific area.

Traditional heat lamp bulbs typically use around 200-250 watts of power and are therefore significantly more efficient than radiant bar heaters. Heat lamps can be quite bright, and the bulbs often come with red filters to reduce the amount of visible light they give off.

Electric heat lamps are usually designed for domestic use and come in all sorts of shapes and styles. They can be wall mounted, recessed or free standing and are often integrated with an exhaust fan for ventilation purposes. These types of units typically have separate switches for the fan and heat lamp components.

Where should I use one?

Heat lamps are designed to provide a small but concentrated source of heat, making them ideal for use in smaller areas such as bathrooms or to supplement heating in larger areas. There are heat lamps that can also be used in the kitchen to keep food warm. Since most of the light is blocked by the red filters (and since they are far less efficient than most “incandescent” bulbs), it is generally not advisable to use heat lamps as your primary lighting unless it is one relatively tight space and where you need heat too.

If you plan to put a heat lamp in your bathroom, make sure your light bulb is IP67 waterproof. Don’t position the heat lamp too close to things like towels or clothes as they can get burned. Heat lamps are most commonly installed in the ceiling to maximize their use—usually just above the area where you step out of the shower to dry off.

Heat lamps are also said to have therapeutic benefits, helping to relieve muscle aches and pains. While sunbathing in the warmth of a heat lamp can be comforting, it’s important to remember not to stand too close to one for too long, as overexposure to the intense heat can burn your skin.

How energy efficient are heat lamps?

Although heat lamps operate at a slightly higher wattage than other incandescent bulbs, they are relatively energy efficient as far as instant heat sources go.

Heat lamps should be installed by professional electricians.

Across Australia, solar panels are a popular way for property owners to eliminate their dependency on the electricity grid. Because these systems are able to use free solar energy, they are often combined with other solutions to ensure unparalleled comfort in living spaces. This is where heat pumps represent a popular pairing option for many homeowners. Because these devices use a different type of renewable energy — heat from the outside air or the earth’s core — this combination offers a variety of benefits to individuals.

Curious what these are? This week’s blog takes a look at it. Read on to discover the benefits of combining solar energy and heat pumps!

A combined system can be coupled with a heat recovery fan

In buildings with draft-free ventilation, exhaust air recovery systems are more common.

By installing a combined heat pump solar panel system in such an environment, heat pumps can recover heat from the exhaust air expelled through the heat recovery system. This is then reused for internal heating and hot water purposes.

Some systems even come with rechargeable batteries for both of the above facilities. This also makes it possible to store solar energy whenever it is available!

By combining these solutions, therefore, optimal operations and savings can be achieved based on actual energy consumption. It is essential that you seek advice from qualified installers and specialists in order to be able to take full advantage of this three-pillar system.

They reduce the carbon footprint of a building

Another benefit of combining solar panels with heat pumps is that properties have a reduced carbon footprint. While this is only significant for residential real estate, it arguably holds more value for commercial and office space. In one such application, a homeowner reported that their home carbon footprint has dropped from 5.4 tons of carbon dioxide per year to just under 2.0 tons – a 64% reduction.

In a country moving towards more conscious consumption and at a time when carbon footprint is a key business concern, a combined solution like this can make a significant difference to business operations.

Energy assessments are important for companies. By reducing the carbon footprint, solar energy and heat pumps make it easier than ever to promote ethical action to win the public’s favor.

The combination of heat pumps and solar panels allows you to use the sun’s energy to the maximum

What many people don’t realize is that residential applications of solar panels allow homeowners to use only about 50% of the energy generated. The rest is fed into the grid, preventing homeowners from storing that energy for later use.

This problem is largely solved with heat pumps. Since these devices emit heat at low temperatures over a longer period of time, the energy requirement is low and kept constant. This means that both air source heat pumps and ground source heat pumps allow individuals to increase solar use by around 20%.

Both technologies are becoming increasingly affordable

For property owners looking to sweeten the deal, the increasing affordability of solar panels and heat pumps is also proving to be a compelling factor.

Beyond the natural price reduction, government rebates and incentives should also be available for both solutions. Solar modules in particular enjoy a wide range of funding and financing options. Switching to such technologies based on renewable energies takes a lot of pressure off your wallet.

The central theses

By combining solar panels and heat pumps, homeowners, managers and property owners can enjoy cost-effective heating and cooling, a reduced carbon footprint and much more, all through affordable technology.

This combined system uses two different renewable energy sources and makes managing energy efficient and comfortable properties easier and more affordable than ever. Therefore, by choosing both solar power and heat pumps, individuals no longer have to sacrifice comfort to enjoy superior energy savings!

Choose the right heat pumps and solar panels and transform your life towards zero energy today!

Off-the-Grid: How Much Electricity Does a Space Heater Use?

Space heaters convert electrical energy directly into heat, making them rather inefficient but simple and affordable units that are often used to warm up tents, RVs and similar objects when they are not connected to the mains, but also to warm up quickly Rooms and other areas in houses and apartments.

Being entirely dependent on electrical power, many people wonder how much electricity a space heater uses and how to power such devices outdoors.

Released: January 13, 2021.

Features and Specifications of Electric Space Heaters

First of all, electric space heaters are not the only way to warm tents, RVs, boat cabins and similar living/sleeping areas while unplugged.

Propane, natural gas, gasoline, and even diesel powered heaters are often used to warm up areas, and they actually do it pretty well.

However, such space heaters burn fossil fuels and remove oxygen from the air in a heated area that requires frequent ventilation. While such equipment is often equipped with low oxygen gauges/alarms, carbon monoxide poisoning is also possible while oxygen levels are still “safe”.

In short: I would never use fossil fuel space heating indoors, no matter how cold it is. IMHO of course. And now back to electric space heaters.

Electric space heaters convert 1Wh of electrical energy directly into 1Wh of thermal energy – 1Wh of electrical energy converted to heat is equivalent to ~3,412 BTU of heat.

Note: Modern air conditioners have heat pumps (inverters), making them much more efficient than traditional electric heaters. If you are in an RV with air conditioning and also have electric space heater, keep warm with air conditioning – your batteries/fuel will last longer.

Electric heaters are commonly rated between 500 and 2000 watts, although there are many models outside of this range.

The table below lists the required current (in amperes) for the most common 120 VAC space heaters:

Power 500W 750W 1000W 1250W 1500W 1750W 2000W Current ~4.2A 6.25A ~8.4A ~10.4A 12.5A 14.6A ~16.7A

For example, if you have a 1500W electric heater and you want to run it for 8 hours (e.g. at night), then this heater will convert 12kWh (1500W * 8h = 12000kWh) of electrical energy into thermal energy.

Also, it is good to know that 1500W is ~ 5100 BTU/h and 12kWh is ~ 41000 BTU.

So if you want to know how much your electricity bill will increase by running a 1500w electric heater for 8 hours at home and on mains electricity, simply multiply 12kWh by your local electric energy price, which is normally in (Euros ) cents per kWh.

How to power an electric space heater while it is off the grid?

There are several ways to power electric space heaters off the grid, but the most reliable method is to generate electricity using a small power generator that runs on gas or propane.

Battery pack/inverter vs. portable inverter generator

In order to supply a 1500 W electric radiant heater with electricity for 8 hours, you need a good 2000 W inverter and a sufficiently large battery pack.

Our electric heater requires:

E (heating) = 1500W * 8h = 12000Wh

Inverters are not 100% efficient units – most common units are 80-85% energy efficient, allowing the battery pack to store at least:

E (battery pack) = E (heating) / inverter efficiency = 12000 Wh/0.85 = ~14100 Wh = ~14100 VAh

Since most battery packs are made of 12V batteries, a battery pack with an energy capacity of 14100 VAh would need the capacity of 1175 Ah.

In order to achieve such a capacity, one must combine large batteries in the battery pack.

For example, if discharged for 8 hours, the Mighty Max ML4D AGM Deep Cycle battery has an actual capacity of ~165Ah.

So to create a battery pack with an energy capacity of 14100 VAh or 1175 Ah at 12 volts one would need 8 such batteries.

A battery pack consisting of eight Mighty Max ML4D batteries could provide:

E (battery pack) = 8 * 12V * 165Ah = ~15800 VAh

that is more than the required 14100 VAh.

So such a battery pack can power a 1500W space heater for 8 hours when using an 85% efficient inverter.

Expenditure? Well, eight such batteries weigh ~415 kg, and that’s a lot to lug around when camping, for example.

The weight of the battery pack can be reduced using deep cycle lithium batteries, but the price of such a battery pack would be very high.

But what about portable inverter power generators?

Portable inverter generators must be operated outdoors because they burn fuel to generate electricity. Such units are very popular and are often used for camping, emergencies and any time you need power while unplugged.

For example, one of the very popular 2000w units is the Honda EU2200i which offers 1800 watts with a maximum output of 2200 watts.

The tank capacity of 0.95 gallons (~3.6 liters) ensures a runtime of 3.2 hours at 100% load (1800 W) and ~8 hours at 25% load (450 W). The device is also very quiet with noise levels of 49 dB at 25% load and 57 dB at 100% load.

The Honda EU2200i weighs 46.5 pounds (~21 kg) without fuel. To power a 1500w electric parking heater for at least 8 hours the Honda EU2200i needs ~2 full tanks of fuel, maybe a bit more – say 2.5 gallons (~9.5 liters) which is ~16-17 pounds of fuel is equivalent to.

So the combined weight of the Honda EU2200i and fuel required to run a 1500W electric space heater for 8 hours is at most 64 lbs (~29 kg), which is far less than ~917 lbs (~415 kg) of the battery pack is from 8 Mighty Max ML4D batteries.

Long story short, when connected to the mains, a 1500W electric space heater doesn’t use much electricity, only 1500Wh (1.5kWh) per hour.

However, when you are off the grid, it is not an easy task to provide this power for a long period of time – the best possible option is to use a portable inverter generator, which directly powers a 1500W (or similar) electric space heater.

Again, never, ever run power generators indoors – carbon monoxide is a toxic, tasteless gas that is very toxic to humans and animals.

If you intend to run the 1500 watt electric heater on high all day, you will need several 24 volt batteries. So make sure you set up the correct battery bank for the inverters.

Hello, I am setting up a DC to AC inverter for my ice fishing cabin. The last fishing season that we were freezing, several friends of mine started using an inverter with a 12 volt battery to run an electric heater. I am interested in the Royal 3000 watt 24 volt inverter, will it power my 1500 watt heater? Thank you

The Royal Power 3000 watt 24 volt inverter should be able to run a 1500 watt heater. The only thing important to note is whether the heater is 1500 watts continuous or peak. This dc to ac inverter will run anything with a peak power of 3000 watts or less, usually when dealing with electronics that contain a heating element the wattage quoted is almost the peak. I recommend checking with the manufacturer or reading the heater manual to make sure it doesn’t go over 3000 watts. Many people often confuse advertised wattage with peak wattage when choosing their inverter. Remember, if an inverter has a continuous rating of 3000 watts and your electronics peak and run above that wattage for several seconds, the inverter will always go into alarm mode. Alarm mode is obviously a feature built into the inverter to protect the user. The last thing you ever want to be is overloading and electronics and burning out all the internal components. There are ways to test the peak pull by using a multimeter and testing the pull while in use. If you haven’t bought your heater yet and want to make sure the system is working properly, contact the heater manufacturer. The same applies to all electronic devices that are powered by your DC to AC inverter. Please also ensure you set up the correct size battery bank for the inverter to run your electric heater for the length of time you require if you intend to run the 1500 watt heater at a high level throughout the day operate multiple 24-volt batteries. All the information given above will also work with the 3000 watt 12 volt AC inverter. Just make sure the battery bank is properly paralleled and maintains its constant voltage at 12 or 24 volts before using any inverter.

If you live in an area with long, cold winters, you probably spend well over $1,000 on heating bills each year.

To save on energy bills, supplement your heating needs with a solar air convection heater that collects heat from the sun to create heat.

Note that they are not powerful enough to heat an entire house. But they are excellent for heating a single room or to supplement an existing heating system.

Pros and cons of solar air heaters

David Schieren, CEO of New York-based energy consulting firm EmPower Solar, estimates that using a solar air heater can save you more than $300 annually on home heating. The savings depend on the size of your home, the amount of sunlight in your climate and the type of heating sources used.

Types of solar air heaters

An outdoor panel collects air from inside your home, circulates it through a flat, heat-collecting panel mounted outside facing the sun, and then returns the heated air back into your home. The panel is attached directly to the outside of your home. Two 4″ holes are required for the supply and exhaust air ducts, and a small fan helps move air through the circulation chambers in the panel. They require connection to a standard 120 volt power supply.

A window mounted unit requires no retrofitting or holes cut in exterior walls; it fits in a standard window opening. Flexible gaskets seal the edge of the unit against the window frame to prevent air leaks. This self-contained unit includes inlet and outlet ports and a thermostatically controlled fan. Since solar air heaters are dark colored to aid in heat absorption, window mounted units block daylight. Units mounted on the window are good for heating small spaces, such as a bedroom. B. a bedroom.

size and cost

Solar air heaters can vary in size, cost and heating capacity. A 32″ x 18″ window air heater panel costs $400-$500 and can heat a small space; a 28 sq ft. The wall-mounted outdoor unit costs $2,700 and can heat 1,000 square feet.

Installation of your solar heating

In most cases it is not necessary to hire a solar professional for the installation. You can hire a general contractor or carpenter to do the work for you.

“The ideal professional for this would be the all-around handyman type, as there’s a bit of carpentry, a bit of plumbing, a bit of glazing, and sometimes a little electrical work,” says Gary Reysa of renewable energy website BuildItSolar.com.

Installation should take a few hours and cost between $60 and $150.

A solar heater complements your existing heating system, so no changes to your HVAC system are required. However, if you are installing large area air collectors, you may need to integrate the system into your existing ductwork to distribute heat more evenly. This could include consulting a solar heating engineer or an HVAC professional.

Do it yourself

To save money, build your own solar system.

“An air heating collector equivalent to a commercial collector that costs $1,200 can be built for a few hundred dollars,” says Reysa. “This significantly shortens the payback period.”

Use DIY solar heating plans to build an inexpensive heating system using materials available at your local hardware store such as: B. Polycarbonate glazing, frame wood and silicone sealant.

Keeps your house warm

Remember that solar air heating is not as important when it comes to energy efficient heating as improving your home’s insulation. Creating an energy efficient home starts from scratch.

An ice storm in the middle of winter has shut down your block’s power supply and the temperature on the thermostat is dropping. Since the utility company is lined with impassable roads, you’ll have to fend for yourself. Are you prepared? If not, prepare by investing in a reliable non-electric heater to keep your family warm when your HVAC system can’t.

Finding the perfect non-electric heater involves evaluating the types, identifying spaces that need heating and determining how portable the unit needs to be. Read on to learn about these and other important buying considerations, and check out some of the best non-electric space heaters below. Each of these can help keep you all warm and snuggly, whether you have electricity or not. We conducted hands-on tests on most of these heaters (there was only one that we didn’t try ourselves) to learn about their ins and outs, and we also did the assembly ourselves. That gave us a better picture of how, when and where these heaters work best.

Before you buy a non-electric heater

Before purchasing a non-electric heater, it is important to understand its limitations. A non-electric heater should not replace a home’s primary HVAC system. Attempting to use a non-electric heater as the primary source of heat for a home has several dangers. Gas heaters can produce high levels of carbon monoxide in a home, which can lead to illness and even death if not carefully monitored. Non-electric heaters also use an open flame and fuel, creating a potential fire hazard.

For these reasons, non-electric heaters should never be left unattended for long periods of time and should never be used in enclosed spaces with sealed doors and windows. It’s also a good idea to have a separate carbon monoxide alarm in the same room as the heater. Look for non-electric heaters that automatically turn off if carbon monoxide levels in a room get too high. If you are looking for a primary source of heat for your home, you must purchase an HVAC system.

Types of non-electric heaters

Non-electric heaters fall into three categories: propane, kerosene, and natural gas. Some heaters are dual fuel, meaning they can run on either propane or natural gas. While all of these types can do the job when it comes to providing heat, they all function differently. Knowing what works best for your specific needs is key to making the right decision when purchasing a non-electric space heater.

All non-electric heaters produce radiant or convection heat. Radiant heaters generate infrared heat using metal tubes that emit heat, causing objects in the room to heat up. With radiant heat, the closer you are to the heater, the warmer it gets.

A convection heater draws in the air around it, heats it, and then disperses that air with a fan. While radiant heaters quickly heat people in the immediate vicinity of the heater, convection heaters can better distribute the heat throughout the room.

If you’re a football fan then you’ve probably seen propane and kerosene forced air heaters warming the sidelines of games in sub-freezing temperatures. Convection heaters have a distinctive cannon shape and work by blowing heat in one direction. They are powerful but noisy, making them attractive for industrial settings like barns, warehouses, and construction sites, but impractical for home use.

propane

Propane gas heaters come in a variety of forms, from tower-style outdoor heaters to smaller portable heaters. Propane heaters use refillable tanks and canisters that range in size from a 16-ounce canister to a 20-pound tank.

Propane heaters that use small canisters are lightweight. When used properly, they are safe for indoor or outdoor use and are easy to transport from room to room. Some are even small enough to take with you on a camping trip. Small propane heaters can produce up to 18,000 BTUs of heat output, which will be explained later. Larger outdoor-only models are tower-shaped, making them ideal for patios and decks. These large heaters can emit up to 40,000 BTUs of heat.

Propane heaters have low oxygen shutoff and tip-over shutoff as standard safety features.

Kerosene

Kerosene burns efficiently and heats up very quickly, making kerosene heaters an ideal option for additional home heating. Like propane, kerosene heaters fall into two categories: radiant and convection heaters. Convective kerosene heaters have a tower shape with a wide base that contains the fuel and a cylinder that contains the heater’s combustion chamber. Their round shape allows them to heat air in all directions. Radiant heaters are rectangular and have a reflector or electric fan that directs the heat generated in one direction.

Kerosene heaters use liquid kerosene, which is available at most hardware stores. Unlike propane, which uses a spark to ignite, kerosene requires a wick to suck up the fuel and burn it. Wicks typically last about a year.

natural gas

According to the U.S. Energy Information Administration Nearly half of homes in the United States use natural gas as their primary heat source. If you’re in that half, then a non-electric natural gas heater could be for you.

Natural gas heaters work similarly to propane heaters, but instead of requiring a tank, they plug directly into the home’s gas line. If the gas line is not already installed, it may require professional installation. A natural gas setup eliminates trips to refill a propane tank but sacrifices portability; If you choose natural gas, the heater must be installed near a fixed gas connection. With that in mind, most natural gas heaters are larger, more permanent devices.

Remember, you cannot connect a propane heater to a natural gas line. Only install heaters designed to operate on natural gas on a natural gas line.

What to Look for When Buying the Best Non-Electric Heater

Before purchasing a non-electric heater, it is important to think about what size and type of heater will best suit your needs. Manufacturers rate heaters for indoor or outdoor use. Weight is also an issue, especially if you plan on moving the heater from place to place. Also consider the tank size as this will determine how often to refill and also determine the wattage of the heater which will affect how much space the heater can heat.

Indoor or outdoor use

Determine if you want to use the heater indoors, outdoors, or both. Outdoor-only heaters produce intense bursts of heat that are not quickly released into the surrounding air. This makes them significantly more powerful than space heaters.

To prevent the accumulation of dangerous carbon monoxide, indoor models should not be used in enclosed spaces such as B. a small room can be used. It’s also a good idea to have a carbon monoxide detector in the same room as the unit.

Many portable non-electric heaters can be used both indoors and outdoors. Be sure to check the ratings of the heater before purchasing.

weight and portability

Decide what is needed from an electric heater. For example, do you need heating for a specific room or a unit that can be moved from place to place? Once you know how to use a heater, you can decide whether you are looking for a portable or a stationary unit.

Portable heaters weigh from 5 to 20 pounds and are available in radiant, convection, or forced air varieties. Many portable heaters feature high-impact construction and large handles for easy portability. Some even come with carrying cases.

Larger non-electric heaters, like the powerful tower heaters used on backyard patios and al fresco dining areas in restaurants, weigh over 70 pounds, not including the 20-pound tanks that power them. Although these are not portable, most have wheels to allow for repositioning. Other permanent heaters include kits that allow for wall or floor mounting.

tank size

Tank size determines how long a heater will last before it’s time to replace the fuel.

Kerosene heaters have tanks that contain liquid kerosene. A kerosene heater with a 1 gallon tank will provide about 14 hours of run time before needing more fuel.

Propane works differently. Because propane is a compressed liquid, it comes in tanks that connect to the heater via a valve and hose. Larger heaters use a 20 pound tank that offers about 10 hours of use. Portable propane heaters use 16-ounce canisters that last about 3 hours.

While most kerosene tanks include fuel gauges, most propane tanks do not, making it difficult to know exactly how much is left in the tank.

perfomance

When choosing a gas heater, it is best to take the Goldilocks approach, as an underpowered heater will make a room too cold, while overheating will make it too hot. The best non-electric heater has to be spot on.

Energy is measured in British Thermal Units (BTUs). More BTUs means more heat output. Most manufacturers also rate their indoor heaters by square feet. For example, an indoor heater with a maximum BTU of 9,000 can heat up to 225 square feet. While 7,000 BTUs are enough to heat a 300-square-foot space, an outdoor heater may need more than 40,000 BTUs to keep an outdoor space warm. Indoor and portable heaters are typically rated at around 5,000 BTUs.

While it’s tempting to buy the most powerful heater you can afford, you may regret it. A heater with a high minimum BTU rating will quickly overheat a smaller space, making it difficult to regulate the room temperature. Unless a sauna is the goal, pay attention to the square footage when deciding which heater will provide just the right temperature.

Best Overall 1 Mr. Heater MH9BX Portable Propane Heater Photo: amazon.com Check Current Price Put heat where it’s needed with this portable propane heater from Mr. Heater. The Buddy weighs just over 9 pounds but packs a punch with a maximum output of 9,000 BTU, which is enough to heat a 225-square-foot room or the inside of a large tent. With its robust design and large handle, the Buddy can be transported almost anywhere. It also has a host of safety features, including a low oxygen shutoff and tip-off shutoff. Performance and portability make the Buddy a great option for a variety of heating needs. Let’s start by showing that the tipping cut-off works. Testing began in a somewhat crowded garage, and the heater was flipped over. It shut down immediately and no propane leaked. In terms of performance, this heater puts out an impressive amount of heat for its size. We used it in a small office and almost boiled it out. The weight is light and portable even with the 1lb propane bottle attached. We used the swivel regulator to attach a hose to a 20 lb tank. Of course, the heater loses some of its portability when mated to a 20-pound tank. This heater worked indoors or outdoors and was tested in a garage, living room, patio and shop. The only problem was the faint smell of the propane and a slight buzz from the pilot light. Once the propane ran out, the heater would get louder and make a popping noise for the few minutes before the propane ran out. Product Specifications Dimensions: 7.7 x 13.4 x 15 inches

With some adjustability, this heater puts out 46,000 BTUs. The warmth is comfortable and the attractive design feels classy in the backyard. Assembly took about 30-45 minutes and involved filling the base with either water or sand (we chose water). You can use the tools provided, but having your own ratchet wrench will help tighten all the screws and covers. The body is made of durable stainless steel that will easily survive a torrential rainstorm (or two). The heater remains maneuverable with two small wheels at the base. At 89 inches tall, this model towers over most of its competitors. In this case, we’re not sure if the height really helped. In testing, we found it was so high that we couldn’t feel the heat as well in colder temperatures. It still radiated that full 9 feet, but the heat rises, meaning those of us on the shorter end of the spectrum couldn’t feel the heat when we were farther from the heater.

Hunters could use it in the blind without announcing their presence. Assembly and setup was easy too. All it took to get going was plugging in the propane and pushing the ignition button. We happened to have this little guy’s 20-year-old predecessor. While the current Little Buddy doesn’t put out quite as much heat, it’s much safer and quieter. A tip-over shut-off feature shuts off power if the bottle falls. It’s good that it has this feature because the 8-inch base is easy to knock over. The downside is the single heat setting and the fact that it can only be used with 1 lb propane cylinders. Product Specifications Dimensions: 11 x 11 x 11 inches

A powerful blower allows it to heat up to 1,200 square feet of unheated space, and its large 5-gallon tank can provide heat for up to 14 hours. A handy fuel gauge lets the user know how many hours of fuel are left. There is a large handle that makes it easy to transport this heater, which weighs about 27 pounds. Safety features include overheat protection and a flame failure sensor. This heater is no joke. We tested it in an 800-square-foot non-insulated store at 50 degrees Fahrenheit. We already have a wood stove in the shop but wanted to see how the Dyna-Glo compares. This heater single-handedly made more heat than the wood stove. In addition, the powerful fan pumps heat around the room much more efficiently. The owner’s manual states that this heater can be used with seven fuel sources, including diesel. Kerosene is the recommended choice because it burns cleaner, but it’s nice to know you have options. However, there were a few downsides. We tested the base model first, so there was only one heat setting. The second disadvantage: this heater is noisy. You can’t have a nice quiet conversation during this time. Finally, the fan needs power, so it’s not useful during power outages. Product Specifications Dimensions: 11.69 x 32 x 16.69 inches

Best for Outdoors 6 Hiland HLDSO1-GTSS Quartz Tube Heater Photo: amazon.com Check Current Price This Hiland quartz tube heater helps save a backyard living space from hibernating in winter. Rated at 40,000 BTU, this outdoor heater generates plenty of heat to ward off the coldest weather. With its stainless steel finish, quartz glass and visible flames, this Hiland tower heater adds both warmth and style to a patio. A rotary knob allows for flame size adjustment, while an automatic toggle switch ensures safety. Thanks to a stable set of wheels as a basis, this heater can also be moved in the garden or on the terrace. As well as being an attractive garden heater, this heater looks a lot heavier than it is. We found it surprisingly easy to move around and even wear. When the flame first shot up the glass tube, we gasped. The white metal cage surrounding the heater initially reminded us of a hamster cage, but once it’s lit it definitely doesn’t look like a hamster cage anymore. It’s beautiful and fun. Although this model doesn’t put out as much heat as other outdoor heaters, it does make it look a lot cooler. The Hiland creates more atmosphere and releases a decent amount of heat into the surrounding 3 or 4 feet. Our only problem was the assembly. The instructions estimated 1 hour for assembly. However, it took us almost 2 hours from start to finish. We even used power tools instead of the manual tools that came with the heater. Much of this time was spent peeling a protective film off the stainless steel panels. Make sure you have more than one person when assembling this heater.

The benefits of owning a non-electric heater

Regardless of what type of fuel you choose and whether you choose a portable or permanent, or an indoor or outdoor model, a non-electric space heater is a useful device in most homes.

Non-electric heaters can supplement a home’s HVAC system and provide heat for those underserved cold spots. You can also expand the utility of an outdoor living space, allowing you to enjoy that patio or deck all year round.

Most importantly, non-electric heaters act as a valuable source of emergency heat, keeping a family warm while they wait for power to return after a home’s HVAC system has been rendered inoperable by a power outage.

The advantages of owning a non-electric heater include the following:

Complements an existing HVAC system

Provides an alternate source of heat during a power outage

Makes unheated living spaces usable in cold weather

Safety tips for using non-electric heaters

Because non-electric heaters involve fuel and flames, it is important to follow certain safety guidelines and only consider models with standard safety features. A non-electric heater should have tilt and low oxygen sensors that shut off the heater when triggered. Safe heaters have a shield that prevents contact with an open flame, such as a flame. B. a glass window or a metal grid.

Despite these safety features, it’s also important to follow some common sense practices when using a non-electric heater. Be sure to place the heater in a low-traffic area to prevent people and pets from bumping into the heater. Place non-electric heaters on level ground to avoid spilling fuel or exposing it to flames. Also, leave a buffer of at least 3 feet between the heater and combustible materials.

Safety tips for non-electric heaters include:

Only buy a heater with built-in safety features.

Leave a buffer of at least 3 feet between combustible materials and the heater.

Make sure the heater is on level ground.

Keep the heater away from high traffic areas.

frequently asked Questions

Now that you know what to look for when buying a non-electric heater, you may still have some questions about the details. Read on for answers to some of the most frequently asked questions.

Q. How can I heat my home without electricity?

The best way to heat a home during a power outage is with a gas alternative. This may consist of a ventless gas fireplace fueled by natural gas or propane, or a gas-fired space heater. Since these devices do not require a power connection to operate, they are an ideal backup during a power outage during a winter storm.

Q. Is there a battery powered heater option to heat my home?

Because electric heaters draw at least 900 watts and up to 1,500 watts, even a large 12-volt battery will not have enough juice to run a heater, making a gas heater the best alternative to electric heating.

Q. What is the safest non-electric heater?

While there is no single heater that is the safest non-electric heater, those with certain safety features are safer than those without. Suchen Sie nach Gasheizungen mit automatischen Abschaltfunktionen, die das Gerät automatisch ausschalten, wenn es umkippt, zu überhitzen beginnt oder einen niedrigen Sauerstoffgehalt in der Umgebungsluft feststellt.

ENERGY bills get very expensive, but there are cheap ways to heat your home.

Forget about cuddling your pets or wearing extra socks. Here are some inexpensive ways to keep your home warm when heating bills rise.

1 Rising Energy Bills… How to Fight Them Source: Getty

Record gas prices have already pushed up energy bills and put pressure on households.

Further price increases are expected in April when Ofgem’s price cap for gas and electricity tariffs is revised.

Switching energy supplier isn’t the most viable option to save money right now, as many grapple with rising costs and more than 30 providers have collapsed since early 2021.

Unfortunately, energy-saving tricks like installing solar panels and attic insulation, while helpful, can cost thousands of pounds.

That’s why we’ve found some affordable ways to heat your home instead, starting from as little as £2.

Some involve DIY work so you may need an expert if you are unsure and don’t forget to shop around for the best deal, but others simply require a quick visit to the store.

DIY design review – £2

The more heat you can keep in your home, the warmer it should be.

But heat can easily escape through cracks in your windows or the front or back door.

Walk around your house and see if you feel any drafts.

You want to keep cold air in and hot air out by sealing any gaps at windows or doors.

Self-adhesive draft excluders can cost you as little as a few euros, with rolls of self-adhesive draft excluder tape available from as little as £3.

You can buy 10 meters of the self-adhesive seal from Amazon for just £2.64.

But it’s a good idea to shop around to get the best price and figure out how much area you need to cover.

The Energy Saving Trust estimates that draft control can save you around £30 a year on your heating bills.

Hot water bottles – £6

Hot water bottles are an inexpensive and energy-free way to bring extra warmth into the home.

Amazon sells hot water bottles for just £6 but shop around to see if there are better deals.

The only other cost is boiling the water and KeepingWarm.co.uk suggests this could be a good way of keeping your bed warm at night so your heating can be turned down or off.

The website states: “All you have to do is pour some hot water into the bottle and screw the cap on tightly, then lay it on your bed for at least 15 minutes before going to sleep.

“The hot water bottle stays warm and slowly disperses heat throughout your bed as you sleep, making it nice and warm.”

Thermal curtains – £12

Thermal curtains are thicker than regular curtains and can also help prevent heat from escaping and keep the cold air out.

Keep them closed when the temperature is coldest to prevent air infiltration.

This is usually in the morning.

Another tip is to keep the doors closed as this can also help maintain heat in any room.

You can get thermal curtains from Argos for as little as £12 but it depends on the size, color and style you require.

Use Google Shopping or PriceSpy to search for the best deals.

Portable heaters – £20

It can be a waste of money to heat rooms you don’t use regularly.

Instead, you could turn down the thermostat and use portable plug-in heaters to heat rooms you use most, such as a bedroom. B. the living room.

You could choose between a plug-in or oil radiator.

Plug-in heater prices start at around £23 at Argos and we found oil-filled radiators at Screwfix for £20, but you’ll need to check they’re powerful enough to heat your room.

We have calculated the running costs of a plug in electric heater and an oil radiator and you should see how this compares to your energy bill.

Smart thermostats – £180

Smart thermostats connect your heating to the internet and let you control it via an app or smart speaker.

You may already be able to set when your heating comes on through your boiler controls, but a smart thermostat may be more flexible, allowing you to change settings on the go and set different times and temperatures for rooms throughout the home.

The most well-known are the Hive and Nest, which can cost around £180 to buy.

Nest estimates users can save around 10% on their heating bills by using a smart thermostat, so you could save in the long run.

How warm should a house be?

First of all, how warm is warm? While you might argue with your roommate or partner about the thermostat, the recommended optimum temperature is 21°C, so anything between 18 and 22°C should do the trick.

How to make a room warmer

While it’s tempting to turn on the heat to warm up a room, there are many other clever ways to make a room warmer. First, having good insulation in your walls and floors helps, but there are other tricks you can use to cheat your way into a warmer space. Read on to learn more…

10 step guide to keep your house warm without heating

1. Rearrange your furniture

Thinking about the placement of your furniture is an easy way to save money on energy and keep your home warmer. “Furniture that covers radiators prevents heat from migrating through the room,” explains Michael. “Even partial blockage limits the amount of heat dissipated.”

It’s also a good idea to move your furniture away from outside walls in winter. “You’ll feel the colder air more if you’re sitting against an outside wall, so try to keep furniture against inside walls. You’ll be more comfortable and less forced to turn on the heat.”

2. Use a terracotta heater

A terracotta heater is a great way to keep warm without using any energy. The idea behind a terracotta heater is that it heats up slowly and holds heat well, meaning up to three terracotta pots can be powered with just one candle.

“A terracotta heater can be a great DIY alternative for turning on the heater, as all you need are some clay pots and candles,” reveals Michael.

3. Invest in insulation

While this is a more expensive method, making sure your home is properly insulated is one of the most cost effective ways to save money in the long run. “Insulating walls is an essential part of a heat-efficient and therefore greener home, as it keeps the heat inside. Whilst the average budget for a full house refurbishment can be as much as £7,000, the savings that result are well worth it.”

4. Think about your habits

It’s common to turn on the heating as soon as the temperature starts to drop, but this can be a costly habit. “If possible, test whether you really need to turn the heating on, especially if it’s earlier in the fall months,” advises Michael.

If you insist on turning on the heater, be careful what temperature you set it to. “It’s estimated that lowering the thermostat by just one degree can save up to 10 percent on fuel bills, not to mention the amount of energy.”

5. Place a shelf over a radiator

Hanging a shelf directly above a radiator is actually a great addition to the radiator as it helps distribute the radiator’s heat more evenly. “By hanging a shelf directly above a radiator, the shelf acts almost like a shield, helping to conduct heat away from the radiator rather than allowing the heat to rise to the ceiling,” suggests Michael.

6. Bleed your radiators

Check your radiators to see if they are heating up properly or not because if there are cold spots you may need to bleed them. “When radiators have cold spots, that’s a sign that air is trapped in them,” explains Michael. “This trapped air prevents the warm water from circulating your radiator properly and causes your space to take longer to heat up.”

Radiator Vent Kit, £9.99, The Range

7. Analyze all drafts

Many older properties with single glazed windows and doors can allow outside air to flow in and heat to escape. “Assess all your windows and doors and see if there are any gaps in the frame that allow drafts to move freely. If there are strong drafts that cannot be easily covered, it pays to invest in stronger doors with at least double the thickness of the glazing,” advises Michael.

Michael adds, “If your budget doesn’t allow replacing doors and windows, or if you’re renting and aren’t allowed to make significant changes, then invest in draft excluders that can cover holes in trusses. However, this is not a long-term solution.”

This stylish draft excluder is the perfect solution:

8. Block your chimney

When the weather changes, you may notice an excessive draft from the chimney. Although fireplaces can be the main focus in a living room, the reality is that an open chimney can create unwanted drafts and heat leaks. “Blocking a chimney may be the only viable option in these circumstances, but you have to be careful to do it properly,” warns Michael. “Never caulk the top of the chimney, especially when using your fireplace, as this will seal off the heat in the chimney and can cause extreme overheating.”

9. Add carpets

Uninsulated floors can account for up to 10 percent of heat loss, especially if the floors are bare and not properly insulated. “If you have a hardwood floor with large gaps between the planks, thick rugs can keep warm air from escaping,” suggests Michael. From the washable designs at Ruggable to the stylish ones at Dunelm, they all help keep you comfortable this winter.

10. Use curtains

A significant amount of heat is lost through the windows of a house; However, curtains are a great solution to prevent this from getting worse. “Curtains help with heat retention by restricting the flow of air between the warmth of your home and the cold outside,” explains Michael. “Heavier curtains act as a barrier and prevent air from escaping the window.”

Keep the chill out and make your room look stylish with these luxurious curtains.

Choosing a heat lamp

Using a heat lamp, preferably one that puts out 250 watts of infrared heat, is your best bet for keeping chicks happily warm. While ceramic screw-in heaters are also effective, ordinary light bulbs, electric heating pads and hot water heaters are not recommended as they do not provide reliable heat at the optimum temperature and there is a risk of overheating your chicks.

If possible, buy a red-tinted light bulb instead of a clear or white light bulb – red light is less stressful for chicks than white light, and chicks exposed to light-dark cycles sleep better, are calmer, and are less prone to feathering peck Some people use two lower wattage bulbs instead of one high wattage bulb so the chicks still have warmth if one of the bulbs burns out in the middle of the night.

assembly of the lamp

Insert the bulb into a metal reflector with an adjustable clamp and ceramic socket and mount the lamp off the ground, face down in the housing. For best results, shine the light at one end of the enclosure to allow the chicks to self-regulate their temperature by moving from the cool end to the hot end. Make sure the lamp cannot fall or touch anything flammable.

Keep chicks comfortable

1st week 38 – 35 °C 2-3 weeks 25 – 35 °C 3-5 weeks 25 – 30 °C 5-8 weeks 22 – 25 °C 8 weeks + room temperature

By adjusting the lamp up and down you can fine tune the temperature of your grow box. Start the lamp about a day before adding your chicks. Use an unbreakable chick-height thermometer to determine ideal heat lamp placement. The temperature (and heat lamp placement) will vary depending on the age of the chicks; The temperatures listed at right are general guidelines from Virginia Tech’s Cooperative Extension Program.

Observe your chicks’ behavior before adjusting the temperature. Comfortable chicks are more or less evenly distributed in the brood area. Cold chicks usually huddle under the lamp and squeak loudly. Overheated chicks often stand far from the lamp and pant with their beak open. Adjust the lamp up or down accordingly until the chicks are comfortable.

A look at the chicks’ legs will also give you an indication of their temperature preference. The legs of cold chicks will feel cold and appear swollen or swollen. The legs of overheated chicks can appear dry, thin and dehydrated.

Solar water heating

Solar water heater is a device that helps in heating water by utilizing the energy of the SUN. This energy is completely free. Solar energy (sun’s rays) is used to heat water. Water can easily be heated to a temperature of 60-80oC. Larger systems can be used in restaurants, canteens, boarding houses, hotels, hospitals, etc. A 100 liter SWH can replace a residential electric instantaneous water heater and save about 1500 units of electricity annually. The use of 1000 SWH with a capacity of 100 liters each can contribute to a peak load saving of approx. 1 MW. A SWH with a capacity of 100 liters can prevent the emission of 1.5 tons of carbon dioxide per year.

How a solar water heater works

The sun’s rays fall on the collector field (part of the solar water heating system). A black absorbing surface (absorber) inside the collectors absorbs the solar radiation and transfers the thermal energy to the water flowing through. Heated water is collected in a tank that is insulated to prevent heat loss. The circulation of the water from the tank through the collectors and back to the tank continues automatically due to the thermosiphon system. There are two types of solar water heaters based on the collector system: A solar water heater consists of a collector to collect solar energy and an isolated tank to store hot water. The stored hot water can be used later at any time.

Main components of solar water heating system

Major components of solar water heater system are

Solar panel (to collect solar energy)

Insulated tank (to store hot water)

support stand

Connecting pipes and instruments, etc.

Applications of solar water heater

Water heating is one of the most cost-effective uses of solar energy. Several thousand new solar water heaters are installed worldwide every year. Solar water heaters can be used for home, community center, hospital, nursing home, hotel, restaurant, dairy, swimming pool, canteen, ashram, hostel, industry, etc. Using solar water heaters can significantly reduce electricity or fuel bills.

Using a solar water heater for any application where steam is generated using a boiler or steam generator can save 70-80% on electricity or fuel bills. A household can save 70-80% on electricity or heating bills by replacing their traditional water heater with a solar water heating system. Solar water heaters are known to have the fastest return on investment in 2 to 4 years depending on usage and fuel replaced.

Types of solar water heaters

There are basically two types of solar water heaters available in the market

Flat Panel Solar Water Heater – Solar radiation is absorbed by flat panel collectors, which consist of an insulated outer metal box topped with a glass pane.

Evacuated Tube Collector – The collector consists of double layer borosilicate glass tubes that have been evacuated for insulation.

Solar water heater with flat plate collector (FPC).

A black absorbing surface (absorber) inside the flat-plate collectors absorbs the solar radiation and transfers the energy to the water flowing through. The Bureau of Indian Standards has standardized this type of solar panel in IS 12933; 2003

Evacuated tube collector (ETC) based solar water heater

An ETC collector consists of double-layer borosilicate glass tubes that are evacuated for insulation. The outer wall of the inner tube is coated with selectively absorbent material. This helps absorb the sun’s rays and transfers the heat to the water flowing through the inner tube. However, these collector types have not been standardized and are sourced from suppliers selected by the Indian Ministry of New and Renewable Energy/Government based on performance testing of the sample system.

COSTS

Approximate cost of solar water heating system is as follows:-

(Costs include cold water tank, hot water tank, supporting structures, heat exchanger, electrical fuse, and on-site installation and commissioning. Additional piping will be charged at actual cost. These are indicative costs only.)
