Choosing the Best Electric Heater That Your Garage Needs

When shopping for your garage’s best electric heater, you’ll definitely be needing a powerful, reliable machine that will serve your needs. You have to consider certain factors that will benefit you in the long run. These appliances are designed with other details you need to explore before making your investment.

Here are pointers to help you shop for an electric garage heater with the best functionality.

The Size of the Heater

Size is very important when choosing your electric garage heater. The heater size you’re looking for will depend on how much garage space you want to heat, the climate, and the insulation level. A small garage will need a different radiator from a larger one. Remember also that an insulated garage is more energy-efficient than an uninsulated one.

Here’s how to estimate the size of the electric heater for your garage:

  1. First, measure your garage’s length and width, then multiply them to get the room’s total square footage. The average 2-car garage can be 22 by 22 feet (484 sq. ft.) or somewhere between 400 and 600 feet.

  2. Check the insulation in your garage to see if the walls and ceiling finishing are insulated. If they are, you’ll use a smaller heater (with fewer BTU or watts). A garage with open rafters will accelerate heat loss.

  3. Once you get the total square footage of your garage, divide it by 200. Multiply the answer you get by 9,000 to determine how much BTU or watts you’ll need for an uninsulated garage. If your garage is insulated, you can multiply the answer by 6,000. In terms of watts, the general rule of thumb is that when buying an infrared garage heater or any other type of electric garage heater, consider 10 watts for each square foot of your space. For example, the Dr. Infrared Heater DR998 has 1500 watts, meaning it can effectively and easily heat up a space of 150 square feet.

  4. When buying your electric garage heater, find one with a BTU output matching the results above. For instance, if your garage is 484 square feet and uninsulated, calculate it as 484 ÷ 200 × 9,000 or 21,780. This means your ideal heater should have at least 21,780 BTU output.

Your heater’s heat settings should be compatible enough to deliver the right amount of warmth your garage requires.

You can also use our Garage Heating Size Calculator to get a more accurate estimated size.

The Electric Heater Location

Your garage heater should be fitted in a convenient place to enable it direct heat to places you use most in your garage. For many, the central part of the garage is ideal, but if your workshop area is in another room, you can offset the machine to direct the airflow to a specific spot.

While considering your heater location, you may have to decide whether you prefer a ceiling or wall-mounted garage heater or a portable option.

The Safety Features of the Heater

The safest electric garage heaters have heavy-duty housing that keeps things that may cause fires away from the heating element. Some models will keep your hands far from the heat to reduce your risks of getting burned. You can also opt for a ceiling-mounted heater if you have pets or children. Don’t also forget to look for models with overheat protection. These types of heaters often shut off when they overheat.

The heater’s tip-over and cool touch mechanism are vital if you want to keep everyone safe. After installing the electric heater in your garage, the chances are that it may trip, even so, when you have kids around. But thanks to technology, some machines are designed with a tip-over switch that activates and turns itself off when the heater tips over, shutting down all the working mechanism to keep everyone safe.

The cool touch feature is another safety feature that keeps the outer body cold when the heater is hot. This prevents the risks of getting burned. So when purchasing your garage heater, choosing one with these mechanisms will benefit you and your loved ones.

The Convenience of Control

Sometimes you want to be able to control your garage heater without distracting yourself from whatever you’re doing. If you want a convenient product, look for one with features like remote control and digital displays, which allow you to control garage temperatures, adjust the thermostat or program the machine’s heating to a particular duration before it turns itself off.

An adjustable thermostat will be of great help, especially if you live in an area that is cold most times of the year. You’ll be able to adjust your electric heater’s temperatures if you buy one with this feature. The thermostat will be sensing the temperature and adjusting the heat accordingly. A machine with a built-in thermostat will be beneficial to you at all times.

120v vs. 240v Electric Garage Heaters

Should you purchase a 120v or 240v heater? This is a question most people keep asking and while there are many good-meaning answers on online forums, most are misleading.

If you have two heaters, one 240v and the other one 120v, both having the same watts per Sq. Ft. (12w/sf is the industry standard), both products will use the same amount of power and watts.

The reason is the 120v system will draw twice the amps/Sq. Ft of the 240v system while the 240v system will draw half the amps/Sq. Ft of the 120v system. According to Ohm’s law, power equals to the product between voltage and current (amps).

For instance, if you’d like to heat 100 Sq. Ft room, both systems will use 1200 watts, and since we know the voltage, we can determine the current or amps for each unit.

The amps for the 240v heating unit = 1200 watts/240v = 5.0 amps.

The amps for the 120v heating unit = 1200 watts/120v = 10 amps.

Thus, while the 240v may seem to have twice the power, it produces the same quantity of heat per Sq. Ft as the 120v heating unit, heats up at just about the same rate and may cost approximately the same amount per Sq. Ft to heat your space.

We recommend that you use 120v electric garage heaters in spaces below 150 Sq. Ft and 240v heating units for spaces above 150 Sq. Ft. This is because a single thermostat has the ability to control 15 amps. Going with our earlier example, 120v can draw at least 15 amps across a 150 Sq. Ft space and so, manufacturers provide 240v heating units for bigger spaces. 

More importantly, you want to ensure your garage space heater’s voltage matches the voltage of your power supply. This is particularly important if you want to replace your current heater.

If you mismatch the voltages, you’ll only receive 25% of the heat and it could be unsafe as well. For example, connecting a 240v heater to a 120v power supply will only give you 25% of heat which isn’t efficient.

(120v/240v)2 = 25%

On the other hand, connecting a 120v electric garage heater to a 240v power source is likely to overload the system, damaging the heater and its thermostat. It’ll also result in costly reinstallation.

(240v/120v)2 = 400%

But in some cases, you may be forced to mismatch the voltages between your heater and power source. The standard power supplies are 120v and 240v but some people’s indoor supplies have 208v rating. In such a case, you can connect a heater with a 240v to a 208 power supply. Note though, that the heat produced will be lower by 25%. In other words, the unit will run at 75% power.

(208/240)2 = 75%

Fixed Vs. Portable Electric Heaters

Electric garage heaters can be portable or fixed. The fixed design needs to be installed in a permanent location. They include ceiling, wall, and freestanding models and are created for large garage spaces. Mounting and wiring should be done well to make them work efficiently. So you’ll have to engage the services of a professional electrician to install the unit.

Portable electric garage heaters are compact, and you can move them to any place in the garage as needed. The only drawback of these portable designs is that they do not have enough power to heat large garage spaces. They’re only sufficient for smaller garages (at most 2-car garages). Most models are designed for ceiling or wall mounting to direct the heated air to particular areas.

Infrared Versus Forced Fan Electric Heaters

Electric garage heaters come in two types – infrared and forced fan. Depending on your preferences and needs, you’ll choose a type that best suits you.

Infrared Heaters


Also known as radiant heaters, infrared heaters generate their heat by running the electrical current through infrared light bulbs that emit infrared light energy. This energy then radiates outward to heat the objects in its way. The infrared light energy is often invisible, and you’ll not see the light, but you can feel the heat.

Forced Fan Heaters

fan-electric-heater image

Forced fan heaters are also called convection heaters. They generate heat when they run an electric current through coils that get hot. A fan will then blow air across the coils to distribute the heat around the room.

Both heaters have their pros and cons, so you’ll have to weigh your needs before choosing the best heater of the two.

Which type Is the Best for My Garage?

To find the best electric heater for your garage, you have to determine your needs first. What will you use the heater for? Do you need heat in the whole garage or a section of it?

If you aim to keep the entire garage warm, you can go for the forced fan heater. Since it uses convection to heat the air and distribute it in the room, it can keep your large spaces warm at all times.

But if you want your electric heater to serve a smaller space within your garage, the infrared heater will serve you better. Infrared heaters emit heat by radiating it outward. This means it only heats those objects in the heater’s direct path. They can only keep small spaces warm.

Safety Precautions for Electric Garage Heaters

Electric garage heaters can generate large amounts of heat. With continual usage, they may overheat and damage the unit or even start fires. If not well maintained, they can also cause other adverse effects. It’s best to keep all flammable objects like oil and gas bottles, and fuel sources far away from your electric heater. Some high-end models come with built-in overheat protection features that shut it off when temperatures get too high.

Portable heaters that aren’t mounted can tip over when you bump into them, causing damage to the unit or even starting a fire. Keep the electrical heater in a secure place where there’s no foot traffic or any other movement. You can also get a technician to mount them on the ceiling or wall to avoid the possibility of knocking it over. Although they come with tip-over systems, it’s better to take precautions with fire risks.

The heaters can be warm or very hot to the touch at times, which can burn you or any other family member. Some models have cool-touch systems, but it’s better to be cautious in order to avoid getting burned.

Tips for Efficient Garage Heating

You can get your ideal electric garage heater, but you also have to take other measures in order to keep your garage safe and heat it efficiently, especially if you have other things in the room. Here are tips to help you.

Have Your Garage Insulated

Understandably, your garage was not built to be warm. So when you decide that you need an electric heater, you should have the garage insulated to prevent the heat from escaping. Insulation will keep the temperatures warm without the heat escaping.

Choose the Right Type of Heater

Before you buy your heater, make sure it’s the best electric garage heater you need – one that will adequately heat your garage. Check the features and specifications against your needs and preferences to make sure you’ve got the right product. Read through all the details and get affirmation before you decide.

Don’t Forget the Doors and Windows

When insulating your garage, don’t leave out the windows and doors. If you can afford it, get garage door openers that come with insulation kits for door protection. Your garage may not be able to keep warm if the heat is escaping through the doors and windows.

Maintenance for Electric Garage Heater

Once you have your heater in the garage, you have to ensure it continues working optimally so it can serve you for longer. That’s why its maintenance is vital. Here’s how to keep your electric garage heater functional at all times;

  • During use, dust particles and other debris may settle on the heater, and if left to accumulate for long, the heater may malfunction. You can dust it once every week to get rid of all the foreign particles.
  • If the heater has grime, you should wipe it away using a damp microfiber towel and dishwashing liquid.
  • Vacuum all the fans, grilles, or vents regularly to clear the airflow.
  • If you notice the reflector is rusty from accumulated dust, scrub the surface or use rust remover to remove the rust.

Benefits of Having the Electric Garage Heater

More people continue to install heating systems in their garages because of the benefits they provide. Built with advanced technology, garage heaters are now more effective and safer to keep in your garage. Ideally, your garage needs the best electric garage heater so you can enjoy the benefits it offers.

Here are additional benefits you can enjoy if you get a garage heater right away:
