Available Heating Options for Your Garage

Forced Air Heaters

Forced air heaters are one of the cheapest heating solutions that run on natural gas. It generates heat through gas combustion and transfers heat to your garage through constant air circulation. Forced air heaters are not as costly as infrared heaters. They can be placed into one corner of the garage for optimal heating for the whole garage. The downside of these types of heaters is that they make a lot of noises because of their gas combustion and fan circulation. Forced air heaters are only effective in closed spaces. Moreover, they tend to kick dust around by their fans which can be an issue if you are doing any sensitive work like painting or water art.

Infrared Heaters

Infrared heaters are technologically advanced heaters which can heat objects directly even if it is in an open space. If your garage is open and impossible to properly insulate then infrared heaters are the best heating solution for you. The downside of infrared heaters is that they are costly in comparison to the other kind of heaters. But infrared heaters are the most efficient heating solution available on the market. If you want to know more about how infrared heaters work or the safety and efficiency of infrared heaters, you can read our blog on this topic. Depending on your heat distribution requirements, you can choose any of these following infrared heating options.

1. Mounted Infrared Heater

Mounted infrared heaters are efficient than any other kind of space heaters available on the market. They are portable in size and can be placed anywhere in your garage. Mounted infrared heaters are energy efficient and powerful enough to cover all corners of your garage. But the heat distribution of a mounted infrared heater is not even. The objects that are directly exposed to its infrared light will be heated swiftly than the objects that are not directly exposed. The image above is an example of a 110v electric garage heater.

2. Floor Infrared Heater

That’s why normal mounted infrared heaters are ineffective for even distribution of heat all over the floor. If you want even heat distribution all over the floor of your garage, then floor infrared heater is the perfect machine for your garage.

The infrared ceiling panel is an alternative solution for your garage which can distribute heat evenly all over the area. They are swift in warming your garage even if they are not insulated properly. Moreover, they can enhance the beauty of your garage to a great extent.

Oil Filled Heaters

Oil heaters consume very less energy and their price is less than infrared heaters. Because of the diathermic oil used inside, oil heaters can provide heat for a good amount of time even after they are switched off. Another positive aspect of oil heaters is that they don’t make any noise. But the only downside to oil heaters is that it takes time a bit longer time to heat up your garage. If your garage is well insulated, then an oil heater can give you optimal heating with minimal energy consumption.

Electric Coil Heaters

Although there are many types of heaters which generate heat through electricity, electric heaters are generally referred to electric coil fan heaters. Their upfront cost is lower than any other kinds of electric heaters. However, they are not as energy efficient as other heaters. The other downside of electric coil heaters is they are unsafe to use. Moreover, their coils don’t last long since the coil inside often gets burned.

Natural Gas Heaters

best way to heat a garage: Natural gas heaters are another great option worth considering. They can provide comfortable heat throughout the winter with the minimal operating cost. Natural gas heaters work based on the gas combustion process. They require constant gas supply which can be provided through a dedicated gas line or a gas tank. Natural gas heaters need a ventilation system as they produce many monoxide gases. However, it is not the best way to heat a detached garage.

Wood Burning Stoves

Wood burning stoves are the cheapest way to heat a garage. They don’t require any electricity to generate heat. If your garage is properly insulated, a wood burning stove can provide you a comfortable heating solution for a long time with minimal cost.

You might need a special building permit or fire inspectors certification before installing one in your garage.

Picking the Right Heater for Your Garage

Before investing in any heating system, you must choose the right kind of heating system for your garage. Depending on the space and design of your garage you might need any specific kind of garage heater. For example, if your garage has two or more entry points and remains open for a longer period of time, then convection heaters or forced air heaters would be ineffective for you. Furthermore, even if you pick the right kind of heater, you also have to choose the correct garage heater size for your garage. Garage heater sizing depends on the space of your garage and the type of heater you are using.

Based on different parameters, a comparison table of different kinds of heater is provided below:

2 Mounted Infrared Heater High High No Quiet High Not Mandatory
3 Floor Infrared Heater High High Yes Quiet High Not Mandatory
4 Infrared Ceiling Panel High High Yes Quiet High Not Mandatory
5 Oil Filled Heaters Medium High No Quiet High Mandatory
6 Electric Coil Heaters Low Low No Noisy Low Mandatory

It is very hard to determine a uniform heating solution for all garage. The cheapest way to heat a garage might not be the most effective solution in all cases. The best way to heat a garage depends on the severity of cold, garage space, design and available fuel in the region.
