​Best Garage Heater - Buyer’s Guide

There are a lot of stuff that might make your garage heater effective or ineffective. Here are some things to look into before deeming a garage heater model superb.

#1 Size of Your Garage

The size of your garage matters a lot. The general floor area, the height of your ceiling as well as the number of cars in the garage are part of this factor. If you think that your ceiling is pretty high, there is more than one car present, and the garage, in general, is big, it is best to get a more powerful heater.

size of your garage

The power rating of garage heaters is usually presented in the form of BTU or British Thermal Unit. Higher Watts and BTU means a more powerful garage heater. If your heater is not powerful enough, you won’t just get insufficient heat; you might even damage the heater itself as well.

This is because having the heater go over its capacity just to heat up a bigger place will only wear out its engine.​

#2 Temperature Rise

The temperature rise in your place or country is also something to consider. The temperature rise is just the difference between the temperature outside your home/garage versus the increased temperature you want to achieve inside.

This is also where the insulation of your home/garage comes into play. Whether or not your place is insulated, and the temperature rise is high, affects the overall performance of a garage heater.​

For instance, if you live in a country that is almost constantly cold, and if space is not insulated, then you will need a more powerful heater to raise the temperature in your garage.​

#3 The Type of Heater

There are four main types of garage heater: the electric/fan-forced, the radiant, the infrared and the gas/diesel/kerosene type of garage heater. Although all four can do their job, they are used for different situations and have different power levels.​

The electric or fan forced garage heater is one of the easiest ones to install. They are easily portable and can be taken anywhere around the garage. Just like your typical electric fan, they convert energy to heat and uses fan blades to distribute heat.

Just plug in it any compatible outlet, and it’s ready to go. However, do mind the power requirements of the heater and the capacity of your outlets before plugging in to avoid accidents.

​The radiant type, on the other hand, works similarly like sun rays. They heat up very quickly. However, they can only radiate heat from the unit to individual objects or even people inside the garage.

It does not heat up the whole garage as other heater systems would. This would only be ideal if you are going to be working in your garage on a cold winter night and you need warmth nearby.​

The third type which is the infrared, is also, again, similar to radiant type heaters. The infrared wavelengths that send out heat also transfer heat or warmth only to specific objects or people. Or even your work area, but not the entirety of your garage.

Unlike fan-forced heaters, the radiant and infrared types are very silent because they don’t make use of fan blades or any engine at all that may produce a loud noise. So, if you want a more quiet heater for small garages or working spaces, these would be ideal.

Finally, the gas/diesel/kerosene operated heaters, are considered to be one of the most powerful heater systems out there. This is perfect for large spaced garages or industrial work areas.

Although because of their power, they might take a little longer to heat up but can increase the temperature of your entire place. No matter how big it is.​

#4 Safety and Protective Features

Though it goes without saying, malfunctioning or unattended heaters are potential fire hazards. A place can get as quickly burned if it is already getting heated up. This is why a lot of heater brands and models have safety features.

Manufacturers usually equip heaters with surfaces that don’t heat up or automatic sensors that shut down the heating system when the machine has reached some degree of temperature deemed unsafe.

Protective features even go as far as electronic sensors that turn off the heater system when it has been accidentally knocked over. So aside from its heating capacity, make sure to get one with safety features to avoid fire accidents.​

#5 Noise Production and Energy Efficiency

Now, just because a heater is efficient, doesn’t mean it has to produce unacceptable noise levels. Or vice versa, just because a heater is noisy, doesn’t mean it heats up real quick or whatsoever.

For all we know, the heater might’ve been defective already which was why it was producing that much noise in the first place. But then, you can avoid these by choosing heaters that are non-forced or oil operated.

Non-forced and oil operated heaters are usually quieter than other types. You wouldn’t want to be unable to sleep at night just because the heater in your garage is on. And as for electricity operated ones: are they energy efficient?

There are lots of energy efficient heaters out there, but there are also a lot that consumes a lot of power can produce electricity. This can cause your bills to spike up. Especially if the season is cold and you plan on using the heater every day for long durations.​

If you are not too sure about the heater itself, you can calculate you would be heater operating costs using the specifications of the heater and a unique formula. Unlike air conditioning systems, portable heaters do not usually have some standard efficiency level.​

However, if you are opting for more great heaters, please do keep in mind that these powerful heaters might need a lot of power or energy to heat up a bigger place at a faster rate.​

On the Side Note...

All these factors listed might not be everything you should look into when buying garage heaters, but these might be some of the most important ones. Especially, if you want to find the best garage heater for you that is durable, efficient and safe.

But then, do not try cutting on the prices if you want quality heaters. Most heaters that come with good safety features might be a little more expensive than others. So if you want to keep your home safe, do not sacrifice safety for price.​


The Verdict

The Dyna-Glo RMC-FA60DGD heater is the best pick for us since its cons are relatively minor inconveniences at best. It can heat up large spaces, and you can use bigger propane tanks, making it more efficient. This is because you don’t have to buy new tanks as frequently.

Furthermore, it is very versatile as it can be used both indoors and outdoors. If you need to use a heater for other purposes besides your garage, this is also an excellent choice. Other units required to be hardwired and mounted, so it’s not as multi-purpose and a bang-for-your-buck option.

The biggest advantage this has over the others is that it has a safety mechanism that automatically stops it when necessary. Plus, it’s one of the more inexpensive options on this list, too! You really can’t go wrong with this one.​
