Forced Air Vs Radiant Garage Heating

Calgarians have two types of natural gas heaters to choose from for their garages.

A “forced air unit heater” using a fan to blow the warmed air like a furnace OR a low intensity “infrared tube heater” that radiates and warms surfaces.

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.

Both options require gas line, exterior venting and an electrical hook up.

To conserve energy, garage heaters should only be considered when installing in buildings that have a minimum of 6 inches insulation in the attic and 4 inches in the walls. If the application has less than this, you’re going to waste a lot money and energy.

Each option comes in various sizes and determined by the square footage, height of ceiling and the R-Value of the application. In our region, a quick ball park calculation can be done using 85-115 btu per sqft. 85 btu per square foot for newer, better insulated applications and 115 btu per square foot for looser, older applications.

The biggest difference between radiant and forced air units is how they perform and how they feel. Infrared Radiant heaters take longer to feel the warmth 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. Also, tools siting in tool boxes/chest will remain cold.

With forced air unit heaters, you feel the warming effects quicker but it can take noticeably 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.

Infrared heaters are normally hung at the back of the garage, angled down on a 45-degree angle and pointed straight at the garage door. Normally suspended 7 feet from the floor and 4 inches from the ceiling.

Forced air units tend to be placed in the corner and pointed across to the other corner. They normally can be installed within 1 inch 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.

Air Force Heating & Air Conditioning only installs Reznor Forced Air Unit heaters at this time. We find that most applications are better suited for them and most Calgarians prefer these models once given all the necessary information to make an informed decision.
