We’ve had a lot of questions regarding garage heating. Of course there are multiple ways it can be accomplished, and in our opinion a natural gas garage heater, radient heater or a boiler with in floor heat is the way to go.


I have some information on natural gas garage heaters below, if you require information on other products please give us a call.

Operating Principle:
When there is a need for heating, the fuel from your natural gas line flows through a gas valve inside the garage heater. A spark or pilot flame ignites the fuel and a flame is produced inside a heat exchanger. When the heat exchanger reaches a pre-set temperature, a fan turns on which blows space air through the warm heat exchanger. The air entering the heat exchanger absorbs the heat from the heat exchanger, resulting in a warmer discharge air temperature. As the fuel is burned, by-products of combustion leave the garage heater through a vent pipe also called a chimney.

Benefits of fan forced gas garage heaters:
•Powerful, fast self contained heat producers. They don’t rely on a centralized boiler to supply heat.
•Low clearance requirements on low profile heaters.
•Most heaters have adjustable louvers to help direct warm air where you need it most.
•Durable. All unit casings are treated for corrosion resistance and finished with a baked-on, high solids paint.
•Huge range of sizes and styles to match the heater to your heating load. If selected properly, you don’t have to worry about under or over sizing.
•The fan can run in the summer without heat to help circulate air.
•Natural gas garage heaters are always ready to run. You don’t need to worry about replenishing your fuel supply.

Drawbacks of natural gas garage heaters:
•Gas fired heaters require more maintenance and service then other types of heaters.
•By-products of combustion require special attention. If the heater is not vented properly, dangerous fumes can enter your garage.
•Clearance requirements must be met. A flame is present. You must be sure combustible materials (fixed or airborne) stay away from the unit heater.
•Dirty, dusty or corrosive atmospheres require special attention.
•Fan forced heaters move large volumes of air which can kick up dust in your garage.

Natural Gas Garage Heater Configurations:
Gas garage heaters blow air horizontally into the space. Adjustable louvers allow for vertical adjustment of airflow. Most major manufacturers also offer horizontal louvers that allow for side-to-side adjustment of airflow. Gas garage heaters for can be broken down into several categories based on the venting type and heat exchanger design:
