Let's figure out how to choose a garage heater by remembering a few key parameters:

Power and estimated area. The output of heat energy depends on the power consumption. 100 W heats 1 m², so for a room of 15 m², you need a unit of at least 1500 W.

Type of installation.

Installation of the heater can be floor, wall or ceiling. This affects the heating zone (for example, the ceiling heats from above, so it will be cold when working in the pit) and the convenience of location (floor heater is easier to move to the right place, but it gets in the way under your feet).
The presence of a thermostat.

The unit helps maintain the set temperature. You will not have to periodically turn on and off the fireplace, which is significant when your hands are in the oil. This element also saves energy consumption.
Dimensions and weight.

The weight of the heater affects the convenience of carrying. Size plays a role only when the garage is heavily cluttered (spare parts, old things, furniture), and then you need to figure out where to place it.
It is important to consider the principle of operation when choosing a heater for the garage. Some models begin to heat immediately after turning on, others after 30 minutes. If you need to replace a wheel or light bulb in the optics in the garage, the long-heating versions will not have time to be useful, or they will have to turn on in advance.

Which garage heater is right for you?

As you can see, there are many different types of garage heaters, but one of the main differences between the models is how they are powered. Heaters fall into three categories: electric, gas, or those that run on a flammable liquid (such as propane or kerosene). As with appliances in our homes, each option has its own advantages and disadvantages.

Of course, price plays an important role when choosing a garage heater, but it can’t be the only factor. For example, kerosene and propane heaters are usually the least expensive, but they emit carbon monoxide and require such ventilation, which can ultimately reduce their heating capacity. Gas and electric heaters work well, but gas heaters usually have a little more heating power, which can come in handy in a large or otherwise uninsulated garage. Be sure to use your garage heater safely
The most important thing to consider when using your heater is safety, and safe operation will depend on the type of heater you have. As mentioned earlier, heaters that burn liquid fuels (in many cases propane and kerosene) emit carbon monoxide. Some of these models are designed to vent the harmful gas outside, but they are more difficult to install On the other hand, a ventless liquid fuel heater is easy to install and helps retain heat, but you’ll need to come up with your own ventilation solution, which may mean that your garage door must remain open during operation. However, these heaters are still safe when operated properly.

5 things to know before buying and using a garage heater

What power sources do you have in your garage? You will need an electrical source to run an electric heater and a gas source to run a gas heater. If you don’t have access to one or either of these sources, your choices will be limited.
What type of heater do you need in terms of wattage? Each type of heater has its advantages and disadvantages, so make sure you take all the information into consideration before you make your decision.
How powerful a heater do you need? Using the size of your garage (or calculating based on your garage size and ideal temperature), you can determine how many watts or BTUs of heat output you will ultimately need, and purchase accordingly.
What will you do with the installation of the heater? If you have no experience with electric and/or gas systems, you should either purchase a portable heater or hire a professional to safely install your model.
How to use a garage heater safely? Make sure you read all of the manufacturer’s instructions, as well as any additional instructions your installer may have.
