Understanding the Types of Garage Heaters
To find the best garage heaters among those are available in the market, what you need to know first is of their types. Like other indoor heating or cooling system, all garage heaters do not function the same way.
Focusing on the style they would heat up your vicinity, garage heaters may be classified into 3 fundamental categories:
Forced Air Garage Heaters:
This type of garage heaters is the most popular ones. Heat, emerging from electricity after conversion, is blown to the surrounding.
A fan fulfills the purpose of drawing the cold air from the surrounding. The air is warmed when it resides on the heating surface and once it is done, the warm air is then blown out.
Probably it is the most popular and can be considered best due to two reasons. They heat the garage within minimum time and produce much heat.
Radiant Garage Heaters:
Using infrared (IR) for the heating purpose is a method we learned from nature. Radiant garage heaters use this technology. It heats up its neighborhood as the sun does to the earth.
Such garage heaters direct the produced heat towards the objects that are nearer. So you would get decent and comfortable warmth if you sit close to it. But, it lacks to provide the same to farther objects. Thus they stand behind fan forced garage heaters when distant heating is your concern.
Convection Garage Heaters:
The heating mechanism of this kind of garage heaters depends solely on some enveloped burning flame or some other heating element. This heating unit would heat up the existing air and the warmer heated air, being light in weight, would move upwards leaving a vacant space below. As a result of the process of convection, the remaining colder air gradually heats up too.
The convection garage heaters do not contain any fan inside it. Hence they become the most affordable garage heaters. But their drawback is that they require a hell lot of time to attain the desired warmth.
They are on both portable and mounted. Baseboard convection heaters are to be mounted.
This criterion of garage heaters also includes those heaters that use water and oil-filled radiators.
If you consider the source of power extraction of the garage heaters, then they may be classified into 2 classes:
Fuel Powered Garage Heaters:
This class of garage heaters varies in the fuel it consumes. The fuel may include liquid or gas fuels, for example, natural gas, kerosene, diesel etc.
Gas garage heaters are more popular. Propane garage heaters are the best among the garage heaters to some individuals due to their high portability and quick service. They are also recommended to use when you have a large area in the back of your mind to cover.
In spite of all these good offerings, gas garage heaters can be way too dangerous. They are not suggested to be used in enclosed regions. They may explode if handled improperly.
Electric Garage Heaters:
The name reveals all. Electricity is the source that they use to power them up and discharge their heating duty. It requires a bit of time to heat up but has no significant fire hazards except that are related to electricity hazard of common home appliances.
Portability is an important feature as far as thermal units are concerned. Of course, you do not have an all-year winter unless you are in a polar region.
Depending on the presence or absence of the feature of portability garage heaters are again of two types:
Portable Garage Heaters:
You don’t want to heat up your garage when it is scorching sun out in the sky. Portable garage heaters should fall in your choice features if you are engaging and smart in handling space of your garage or room.
Ceiling or Wall Mounted Garage Heaters:
Space is not your headache always. Rather you may want an instant supply of heat. If you are in the same harmony then buy a mounted garage heater.
Garage Heater buying guide
The market tenders you hundreds of garage heaters each varying in their features and specifications. It is not an exceptional fact that you would find yourself intimidated while finding the best garage heater that serves your purpose. Do not forget to consider the following parameters while choosing your best garage heater:
Type of Garage Heater:
There are various types of garage heaters. What you need to do is to understand your circumstances at first. Give a quick scan to the section above containing the types of garage heaters unless you have already done so.
Try to answer some basic classical questions: What place am I considering to keep warm? Is it large or small? What should be the heating period? Do I mind a delay in heating initialization? Can I afford space to mount the heater?
Garage heaters come up with a power rating. You will find it both inscribed on their body and in the specifications. The power rating is usually provided in BTU (British thermal unit). It may also be given in Watts.
Remember the simple equation: Higher the power ratings, more powerful the heater and greater the region would it cover. Also, do keep in mind that the inscribed power rating is referring to the best possible scenario. So buy the garage heater that would read its power rating a bit more than that you require.
If your garage is small, then you should purchase an infrared or radiant heater. They are best for such surroundings since they love to warm people and objects more than heating up the air. A fan-forced garage heater may also be suggested in this circumstance. But keep the size of the heater small to medium.
For larger spaces heaters of 4 to 5 kiloWatts are the best. But to cover a smaller volume, keep the power rating around 1500 Watts.
The Power Requirement Is Again Dependent on the Following Factors:
One Car or Two-car Garage:
To heat a specific region of your garage, select the power requirement for smaller garages.
The Height of the Ceiling :
Note that the garages having a taller ceiling should be considered large, even if the area is not that bulky.
Power rating should be chosen keeping the outdoor temperature in mind. The desired temperature is certainly higher than the existing outdoor temperature. The difference is the “temperature rise”. Smaller garages may require garage heaters having higher BTUs for colder countries.
Insulation on the Spot:
Insulation refers to good quality walls, windows, and doors that are heat resistant. Places having sufficient insulation would require heaters of slightly less power rating. But for insulated structures, heaters need additionally more power than calculated.
Once the power consumption is calculated and sorted out, just don’t buy a garage heater and plug that in; it may not work. As industrial units require more power, many industrial heaters require 220 to 240 volts instead of standard 110 to 120 volts.
Before you buy a garage heater check the required voltage since that having higher voltage ratings won’t work at all in residential plugs. But don’t worry about it. You should not hesitate to purchase the higher voltage rated device if, fortunately, your industrial place has got a 240 volts outlet.
Almost all the heaters would show up amperage rating ranging from 15 to 20 amps. Ensure that the electrical socket you have can afford the volts and amps your heater demands.
Hardwired or Plugin:
Electric garage heaters come up in both the forms- hardwired and plugin. Both have their individual pros and cons.
The hard-wired ones are more efficient in terms of power delivery and area of coverage. They often lack mobility and portability. On the other hand, the plugged-in ones may offer you a good deal of flexibility, but won’t let you heat a big space.
Count the safety factors a garage heater provides, for the quantity itself, will reveal all. Safety factors include a few parts of the device itself.
Thermostat and Regulator
The thermostat controls the temperature at which the user wants the temperature to get stabilized. It is a part and parcel of an electric heater. In most case, there is a knob that can be rotated within some gradations including high and low extremities. It is known as a regulator.
The thermostat together with its regulator prevents the device to get overheated. Otherwise, the heater may get burnt and cause a considerable loss of health and wealth.
Automatic Safety Shut Off
Almost all the modern garage heaters do possess this feature. This feature enables the heater to shut off immediately as soon as the thermostat operates. Don’t purchase a garage heater without ensuring that it has this feature within it.
Many garage heaters possess a light (often an LED) to indicate any kind of caution or hazard situation. This may happen due to a number of reasons. You need to plug out, switch off or put off the heater as soon as you see it lit up.

Garage size and heater power rating
It is a simple and practical fact to realize is that if you buy an enormous garage heater for a tiny garage that you may have, then the bills that you would need to count may compel you to lose your interest to heaters. To ensure that this is not your case you need to know some facets of garage heaters regarding the size and power of the heater you should buy.
Garage heaters are rated in BTU and/ or Watts. Both are units of power consumption or capacity. A certain heater may be rated only in one unit while you may require the other equivalent in practice. Use these two simple conversion techniques-
Watts x 3.41 = BTUs
BTUs / 3.41 = Watts
Determining Garage Heater Size and Power Rating
The size of your required garage heater is dependent on a number of parameters. The parameters include the degree of insulation, the desired temperature rise, outside temperature and the most importantly the volume of your garage. Note that the volume of the garage is again the area of your garage times the height it stands.
Approximate Power Calculation:
Well, it’s a heck lot of things to consider. Forget all. To keep it simple but still working, consider 10 watts against each square feet of floor to cover. So it comes up to the approximation of the following equation-
Watts required (approximately) = length x width x 10
For an instance, if your garage covers 26 ft x 26 ft (a 2 car garage)or 676 square feet of floor area then the wattage of the required garage should around or greater than 6760 Watts.
Precise power calculation:
There’s no better option other than a precise calculation. To do so, take all considerations back to the calculation.
What’s a temperature rise?
The terms “temperature rise” means the difference between the temperatures you want inside the garage and that of the outside environment. For power calculation, take temperatures in the Fahrenheit scale.
What about insulation?
The extent of insulation can be measured by checking the R-value. It is the thermal resistance of the materials and refers to the degree of trapping and retaining heat. Higher the value of R, better they preserve heat, better insulation they provide.
For heavy and average degrees of insulation the rating is to be considered 0.5 and 1 respectively, whereas, for low isolation, it is to be reckoned rated as 1.5. If no isolation is there, we need to consider the rating to be 5.
The Ultimate Equation:
The final verdict comes up in the form of the equation below:
(Insulation rating x volume x temp rise) / 1.6 = BTUs
Finally convert the BTUs into Watts using former equations, if needed.
For instance, if it is a 2 car garage with 8 ft height,
Volume = area x height
=676 x 8 cubic ft
=5408 cubic ft
Temp outside: 70 degree Fahrenheit, Required temp: 50 degree Fahrenheit
Temp difference: (70 – 50) = 20 degree Fahrenheit
Insulation type: average (rated 1)
Then the required BTUs,
BTUs = (1 x 5408 x 20) / 1.6
Watts = 67600 / 3.41
Garage Heater Safety Measures
Any thermal system you buy, there remains a bunch of hazard possibilities. Let’s draw our attention to some of them.
A Stable Base:
Don’t get relaxed just turning your garage heater on, whether it be a gas or an electric heater, especially if it is a portable one. Make sure that you put your heater unit on a solid and firm basement and stable enough to absorb any vibration produced by it.
The same goes for ceiling or wall-mounted ones; rather it is more important for them since they may produce a greater impact if ill-treated. Avoid any chances of knocking it over.
Keep enough space around the garage heater to allow clearance. Not caring about this particular act may result in burns and bruises. You may lose yourself completely as many electrically powered units connect 240 volts.
Gas heaters have greater threats. A trace of flammable or combustible materials in its vicinity may bring about a fatal situation. So, keep it away from solvents, gasoline, paints, etc. Besides, papers, blankets, bedsheets, and curtains are some other things that you don’t want to burn as well. Keep them away!
Kids and Pets:
Kids are notorious when hazardous stuff is around them, so they are pets. Warn and supervise them enough to ensure that they won’t bump the heater away!
No Blocking of Valves:
The intake and exhaust valves are of great importance because they are the key path of gas movement. Any blocking may lead to a severe accident.
Only Intended Use:
This is a space heater, not a dryer of shoes or clothes! Try to use it as they are intended.
Cleaning and Maintenance:
Take great care in order to clean or maintain. Turn it off and disconnect the power supply. Give the heater some time to get back to a cool state.
Repairing and Modification:
An electrician or technician is recommended for any repair. Please do not attempt to modify it by yourself.
Do Not Leave in on the State:
Do not leave your heater turned on while you are not intending to use it. Turn it off and if possible disconnect the supply while going somewhere else.
Here are some frequently asked questions and their answers.
How many BTU does it take to heat a 2 car garage?
A basic rule of thumb for forced-air heaters is 45,000 Btu to heat a two- to 2-1/2 car garage, and a 60,000 Btu garage heater for a three-car garage. The makers of low-intensity infrared tube heaters say that 30,000 Btu can heat a two to 2-1/2 car garage, and suggest 50,000 for a three-car garage.
What size heater do I need for a 2 car garage?
Two-car garages (450-700 sq ft) require a 3600-7000 W unit (electric heaters) or 12,000-24,000 BTUs/hr (for the propane ones) Three-car or bigger garages (700-900 sq ft) need a 7000-9000 W unit (or 24,000-31,000 BTUs/hr).
Where should heater be placed in garage?
To be most effective, garage heaters should be placed in the coldest corner of the room and directed towards the center.
What is a good temperature for a garage?
What temperature should you keep your garage at? It depends on how you use your garage and where you live. A good rule of thumb is to always keep your garage above the average dew point so condensation doesn’t form. This is usually around 40°F for inland states and around 65°F for coastal states.
Can you heat an uninsulated garage?
So what’s the best way to heat an uninsulated garage? Use propane heaters for high powered, silent and odorless heat. Opt for a radiant style for a small-medium garage, or a torpedo style for a larger space. For an electric option use infrared heating as it’s more durable.
Is it OK to use propane heater in garage?
Propane heat is an economical and safe means of heating your garage without breaking your budget. Small garages of 1,000 square feet or less can use a shop heater with a rating of 45,000 to 75,000 BTUs per hour.
