Energy Efficient Garage Heaters for a Warmer Garage Lifestyle

Winters can be harsh.  There is nothing worse than getting into a cold car in the morning.  If you work in your garage, you will definitely want to be warm all year round. In Alberta, natural gas is still the most economical choice for heating spaces. The mentioned units are considered mid-efficiency (83% or less) and are a great balance between upfront affordability and operational costs.

Alberta Mountain Air offers two types of natural gas heaters: 

FORCED AIR UNIT HEATERuses a fan to blow the warmed air like a furnace

LOW INTENSITY INFRARED TUBE HEATER –  radiates and warms surfaces.

Both options require gas line, exterior venting and an electrical hook up. To conserve energy, garage heaters should only be considered when installing in garages that have a minimum of 6 inches insulation in the attic and 4 inches in the walls. If the application is any less, you will waste a lot money and energy.

Alberta Mountain Air offers many styles and brands of garage heaters including Lennox, Reznor, Hotshot and more.

Garage Heaters are determined by the square footage, height of ceiling and the R-Value of the application. The biggest difference between radiant and forced air units is how they perform and how the warmth they provide.

Alberta Mountain Air offers two types of garage heaters:


Infrared Radiant heaters take longer heat up a room because they first have to heat the items in the garage, but once the concrete floor is heated up, the environment feels more comfortable and consistent. One of the down sides is both you and objects need to remain a fair distance away from the heat source, especially vehicles. If you are working with tools, you will find that they will remain cold. Infrared heaters are normally hung at the back of the garage, angled down on a 45-degree angle, pointed straight at the garage door. Normally suspended 7 feet from the floor and 4 inches from the ceiling.


With forced air unit heaters, you will feel the warming effects quicker however it will take longer to reheat an area after the garage door is opened & closed. If you plan on working with stains and paints on a regular basis, you will want to turn the unit off or go with radiant because the fan on forced air units can stir up sawdust or small debris. The upside is with these models you can use the “fan only mode” during hotter seasons or to help with ventilation.

Forced air units tend to be placed in the corner and pointed across to the other corner. They normally can be installed within 6 inchs of the ceiling and approx. 18” from the wall (serviceability) and have louvers to direct the heat.

Typical garages are best heated with forced air units. They’re considerably more compact and installed out of the way, saving precious space for working. Garages with high ceilings tend to be heated better by radiant tube heaters. You don’t have to worry about all the hot air rising to the ceiling or hitting your head on the tube.
