Buying guide: Buying The Best 120v Electric Garage Heater

What Are the Different Types of Heating?

Firstly, you might have read a lot about radiant heaters and infrared heaters. These are largely the same type of heater. They work by heating heat objects rather than the room’s air.

You feel the warmth quickly and directly but may take time to heat the entire room. These heaters offer consistent heat without any blowing out of air or dust particles and many come in compact sizes, making them ideal for garages.

Space Heaters or fan heaters use convection heat. Simply put, this is when the warmed air rises and displaces cold air downwards, back down towards the heater. Fan heaters combine the warming capability of a heater and air distribution capacity of a fan.

Free-standing vs. Wall Mounted – floor space is one of the most precious things in a garage! When deciding on an electric garage heater, remember to take into account its size and how it works. Does it need to be on the ground or workbench? Or from the ceiling or wall?

If space is limited in your garage, you might consider a wall mount. It’s also very important that your heater is away from flammable materials at all times, so when installing your heater, take particular care of what is around it.

If you want a free-standing heater, remember to choose one with tip-prevention and which has high-quality safety features…just in case!

IPX4 – many of the above electric garage heaters have IPX4 structures. An IP rating determines how resistant a material is, with each ending number a different element. IPX4 essentially means water resistance, in this case, water splashing. If your garage is prone to leaks, or you want the option to use your electric heater outdoors in patios/when camping, IPX4 is an important feature to look out for.

Here Are Some Effective Heating Tips You Should Consider

Maximizing your garage’s insulation is key to keeping heat indoors and circulating the room. How? There are several ways you can insulate your garage, many of which are very cost-effective and will save you money in the long run.

Insulation materials – there are a variety of materials you can use to insulate your garage. These materials act as a blanket that traps heat and stops it from leaving through walls, air spaces, and the ceiling. Fiberglass is one of the most common types and can come in long-blankets or loose-fittings, depending on your needs. Foam is another useful insulator.

Air-sealing – Reduce the amount of air that leaks out of your garage are important in ensuring hot air stays in place. It also helps improve air quality and ventilation, especially in extreme hot or cold weather. Air escapes through cracks and openings (around window frames e.g.) and so naturally, your main goal is to ‘seal’ these weak spots.

Garage door – Don’t forget about one of the biggest things in your garage – the door! Garage doors are typically huge to allow cars, machinery, and more to pass through and as such may lose lots of heat by being poorly insulated. As well as windows and ceilings, remember to insulate this big fixture and create a wall to keep heat in.
