Space heaters are typically small heating units that you use to supplement your primary heating system.

If they can’t be used to heat the whole house, can they be used to heat a large room, including garages and workplaces? If yes, will they increase your heating bills?

In this article, I’ll answer these questions and recommend some of the most energy efficient space heaters for large rooms. Most of these units have higher BTU ratings and energy-saving features intended to help you cut on your heating costs.

What’s important is to make sure you have properly sized your space heater. A unit that is too small will have to work twice as hard to warm a room, wasting a lot of energy, and even then, the set temperature might not be reached. If the heater is too large, it will warm the room too quickly, leaving some zones

Benefits of Energy Efficient Space Heaters

Using wood stove as energy efficient space heater for large room

Home heating is one of the most costly expenses in the home. According to the US Energy Information Agency (EIA), the average household spends just over $900/year on home heating if using electric heating.

Others pay a lot more depending on the type of fuel. The average cost of heating with propane, for instance, is over $3,000/year. This equates to just over 5% of the median household income in the US.

Switching to energy-saving electric heaters can significantly reduce your energy bill. It’s estimated that supplementing with Energy Star rated heaters alone can cut your heating expenses by a massive 30%.

The heaters in older homes typically operate on 65% AFUE (more on AFUE shortly). It means that for every 100 watts of electricity drawn from your home’s supply, 35 watts are lost. Modern, energy-efficient heaters are up to 90% efficient, meaning that only about 10% of electric energy is lost.

Other advantages of energy-efficient heaters include;

  • Greater indoor comfort: Energy efficient heaters are designed to deliver optimal comfort. They’re not just about pumping heat into your home. They attempt to balance other factors, including humidity and air movement, to provide the perfect climate. The result is healthier, more comfortable indoor air.
  • Longer equipment life: Energy-efficient heaters are also long-lasting because they self-regulate to reduce the internal components’ load. Many of them go on and off or reduce/increase heating temperatures as necessary to deliver maximum comfort. In the process, the heating and blowing components work less, thus a prolonged life.

Important Energy Efficiency Indicators to Look for in a Space Heater

Before we look at the many other energy efficient room heaters’ many other qualities, let’s discuss the energy-efficiency ratings and standards.

There are five such ratings/standards to keep an eye out for are AFUE for gas-powered heaters, SEER and HSPF for heat pumps, COP values for chillers and heat pumps, and Energy Star certification for all types of heaters.

AFUE

AFUE stands for Annual Heat Utilization Efficiency. It is a measure of how efficiently a gas furnace (or boiler) operates over an entire heating season.

AFUE is expressed as a percentage of the energy consumed by the heating system converted into useful heat. For instance, a 70 AFUE gas heater converts 70% of the gas energy it consumes into usable heat. For every BTU of gas consumed, it produces 0.7 BTU of heat.

AFUE is one of the most accurate efficiency measurements because it takes a lot of factors into consideration. Whereas steady-state metrics are only concerned with the heater’s efficiency when running, AFUE considers the on-off cycling, pilot lights, etc. Modern gas heaters are rated between 78-90% EFUE, but some areas efficient as 97% AFUE.

HSPF

HSPF is short for Heating Seasonal Performance Factor. It is a measure of how efficiently heat pumps operate in heating mode over the entire heating season. Heat pumps are air conditioners that work as supplemental heat sources in the cold season by extracting heat from outdoor air and dumping it inside the house.

HSPF is calculated by dividing the total number of BTUs of heat produced over the heating season by the total amount of electricity (in watts) drawn by the heat pump over the same period.

Most heat pumps are rated between 7.0 and 8.0 HSPF. The higher the rating, the more efficient the heat pump. These figures are usually converted into percentages by dividing the HSPF value by 3.414.

The resulting percentage, often in the 200% to over 300%, is the amount of heat in BTUs the heat pump will generate for every watt of electricity consumed.

Therefore, a 7.0 HSPF heater is 7/3.414 = 205% efficient, which means that for every watt of electricity drawn, it produces 2.05 BTU of heat.

COP Factor

COP is short for Coefficient of Performance. It measures how efficiently a heating (or cooling) system operates at a single outdoor temperature condition. When applied to heating appliances, the temperature condition is usually 47°F. A higher COP rating means that the device has high efficiency.

There are two broad ways to determine an appliance’s COP rating. The first option is to divide the total BTUs of heat produced by the appliance by the BTU equivalent of electric power used to produce the heat.

A heater that draws 4,000 watts (equivalent to 4,000 x 3.414 = 13,648 BTU) to generate 42,000 BTU of heat, therefore, has a 3.08 COP factor.

The other way to determine a heating appliance’s COP rating is to divide the 3.516 by the amount of electricity (in kW)/tone used by the system.

Energy Star Certification

Finally, the Energy Star certification isn’t a rating per se. But, it’s still one of the most important factors when shopping for an energy-efficient HVAC appliance.

According to the Energy Star website, Energy Star qualified and certified are designed to use less energy than standard systems. When installed properly, these systems can save you a lot in energy costs.

Energy Star qualified heaters are also designed to reduce air quality problems by reducing dangerous carbon monoxide backdraft risk.

Above all, Energy Star certified/qualified heaters are incredibly durable. They employ advanced technologies and high-quality components, resulting in longer appliance life and warranties than standard appliances.

Which Types of Heaters are the Most Efficient

There are three broad categories of space heaters, i.e., infrared, ceramic, and oil-filled. Here’s how the three rank in terms of energy efficiency;

different types of the best energy efficient space heater for large room

Infrared Space Heaters

Infrared space heaters are radiant heaters. They emit perfectly safe infrared rays that warm people and objects directly in their path. Since they warm you directly, you feel the warmth instantly. By contrast, convective heaters depend on air movement to reach people (and objects) in the room.

This mode of operation makes infrared heaters extremely efficient. If properly installed, they will direct most of the heat where it’s needed, resulting in very little energy loss. The overall efficiency, however, also depends on the type of heating element used.

Oil-Filled Radiators

Oil-filled heaters, as the name suggests, are also radiant heaters. They depend on natural radiation to transfer heating from the heating appliance to the people in the room.

But, they work slightly differently than infrared heaters. A heating element inside the unit heats oil inside a permanently sealed tank. Then the oil radiates heat out of the unit and into the room.

What makes oil radiators extremely efficient is that the oil used can retain heat for long periods. As such, oil radiators can continue emitting heat even an hour after you’ve turned off the heater.

This is different from infrared and ceramic heaters that stop emitting heat as soon as the heater is turned off.

Ceramic Space Heaters

Finally, ceramic heaters are convective heaters. They generate warmth through a heating element. This warmth is then carried out of the heating unit and distributed throughout the house via a fan system. These heaters are known as ceramic heaters because they use a Positive Temperature Coefficient (PTC) ceramic plate as the heating element.

Ceramic heaters are also very efficient, but not as much as the first two options. They distribute heat very well, which is perhaps their biggest strength. However, the blowing action can push warm air outside the house. Additionally, blowing is known to cause dust and allergens. These can offset all the gains made.

Other Options

As you may have noticed, all the three categories of space heaters above are electric heaters. If you’d prefer to use other fuels, propane and gas are great options.

They are both renewable energy sources and guarantee tons of heating power for every BTU of fuel consumed. Many propane space heaters, for instance, are 70-96% efficient. Kerosene is another option.

The only downside is that these heaters are not safe for indoor home heating. They present a significant fire risk, partly explaining why they are rarely mentioned when discussing space heaters. Additionally, maintenance is an issue. Maintaining and refilling gas heaters negates some of the efficiency qualities.

That said, though, gas and kerosene heaters make excellent and efficient heating options for unusual spaces such as garages and basements. If you choose to invest in one, keep in mind that vented models (which are the recommended option) are less energy-efficient than unvented models.

Determining your Heating Needs: Does Size Impact Efficiency?

Yes, size impacts heating efficiency. Two size factors are especially important – the heater’s capacity and your room/home’s dimensions.

A space heater that’s too big for the room will maintain the desired heating temperatures, yes. But, at what cost? You’ll likely pay a lot more for the extra heat. What’s worse, you may not even need the extra heat because the right-size heater is more than capable of delivering the heating levels required in the space.

Moreover, an overly small heater (relative to the room) will go on and off too often. This on-off operation negates all the efficiency gains. It also creates preventable noise, thus undermining indoor air quality.

Sizing your Heater

The rule of thumb is to have only 10 watts of heating power for every square foot of space. This means that a 1.500-watt heater should be enough for a 150 Sq. Ft. space and a 4,000-watt model sufficient for a 400 Sq. Ft. area. Note that if you intend to use the appliance as a supplemental heat source, then you need an even smaller heater.

Three other considerations to make here are as follows;

  • Infrared heaters: Being extremely efficient, infrared heaters can warm larger spaces. So, you may not necessarily need a 4,000-watt infrared heater for a 400 Sq. Ft. space. You’ll need less.
  • Ceiling height: The above figures assume an 8-foot ceiling. If you’re dealing with a higher ceiling, adjust the final wattage figure by 24% for every one-foot increase.
  • Insulation: The above figures also assume standard insulation. If your room/home is poorly insulated, use 12 watts/square foot instead of 10 watts/square foot.

Tips to Save Energy with Space Heaters

How to save energy with the energy efficient space heaterEven after you’ve picked the right energy efficient space heater for large room, your work isn’t done. You need to take steps to extract even more useful heat from your heater. The following tips should help;

Correct Placement

The positioning of your space heater is crucial. Most space heaters are meant to install on the wall or floor, but some install on the ceiling or under windows (baseboard models). Then, there are also portable models that you can position as you please. Make sure to install the heater as advised by the manufacturer and away from obstructions.

Consider Professional Installation

Professional installation is critical to space heater efficiency. Unless it’s a portable model, having an HVAC professional identify the right location and install the unit properly can dramatically improve air circulation in the room, effectively reducing the thermostat setting needed to achieve optimal indoor comfort.

Properly Insulate your Home/Room

No matter your heater’s energy efficiency, if your home is poorly insulated, you’ll continue using more energy to warm up the place. Adding insulation t your attic, replacing old/missing caulk, sealing your ductwork, and adding weatherproofing to drafty doors and windows can increase home insulation for increased heating (and cooling) efficiency.

Maximize on Heating Controls

Energy-saving modes, timers, and remote controls are just a few controls that can help you maximize energy utilization when using a space heater. For instance, you can leave the heater on when going to sleep, but you could set the timer to switch it to Sleep Mode to save energy. You’ll save a lot of money.

Properly Maintain the Heater

Finally, an efficient heater is a well-maintained heater. If the appliance is left to collect dust for months without scheduled maintenance, it won’t be as efficient as it should be. The same applies if there are broken, malfunctioned, or loose parts inside the appliance.

Wrap Up

Now that you know how to pick an energy efficient space heater for large room, feel free to go shopping. We want to stress one thing – efficiency doesn’t end with buying a high-efficiency electric heater. How you use the heater also matters. Make sure to use the heater in a manner that conserves energy.

Above all, don’t forget to consider other qualities of a great space heater, such as low-noise operation, safety features, and warranty. Happy shopping!
