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.

Why Garage Heaters are Necessary in Calgary, Alberta

Garage heaters are essential in Calgary, Alberta, especially during the winter months. Temperatures can drop to as low as -30°C, and without proper heating, it can be impossible to work or relax in your garage. In this article, we will explore the different kinds of garage heaters, why they are necessary, and the pros and cons of each type.

Garages are used for more than just parking vehicles. They serve as a workspace, storage area, and a place to relax. During the winter months, garages can become extremely cold, making it challenging to use them for their intended purposes. By installing a garage heater, you can make your garage comfortable and functional year-round.

There are two main types of garage heaters: forced air garage heaters and vented garage heaters. Both types have their pros and cons and are available in either natural gas or electric options.

Forced air garage heaters work by blowing hot air into your garage. They are available in both natural gas and electric options. Natural gas forced air heaters are the most common type of garage heater in Calgary, as they are highly efficient and cost-effective. They are also easy to operate and can be controlled by a thermostat. The downside of natural gas forced air heaters is that they require a gas line to be installed, which can be costly.

Electric forced air heaters, on the other hand, are easy to install and operate, as they simply require an electrical outlet. They are also highly efficient, as all of the energy they use is converted into heat. However, they are more expensive to operate than natural gas heaters, as electricity is more expensive than natural gas.

Vented garage heaters are another option for heating your garage. They work by burning natural gas or propane and venting the combustion gases outside. Vented heaters are available in both wall-mounted and ceiling-mounted options.

Natural gas vented heaters are highly efficient and cost-effective, but they require a gas line to be installed. Propane vented garage heaters, on the other hand, are more expensive to operate than natural gas heaters, as propane is more expensive than natural gas. They also require a propane tank to be installed, which can be costly.

Electric vented heaters are also available, but they are not as common as natural gas or propane options. They are easy to install and operate, as they simply require an electrical outlet. However, they are more expensive to operate than natural gas or propane heaters, as electricity is more expensive than natural gas or propane.

The best garage heater for you will depend on your specific needs and budget. If you have access to a natural gas line, a natural gas forced air garage heater is the most cost-effective option. If you do not have access to a natural gas line, an electric forced air garage heater is a good option, but it will be more expensive to operate.

If you prefer a vented heater, a natural gas vented garage heater is the most cost-effective option. However, if you do not have access to a natural gas line, a propane vented garage heater is a good option, but it will be more expensive to operate. Electric vented heaters are also an option, but they are not as common as natural gas or propane options.

The Pros and cons

There are pros and cons to each type of heater for the modern or retro garage. Forced air heaters are highly efficient and cost-effective, but natural gas heaters require a gas line to be installed, and electric heaters are more expensive to operate. Vented garage heaters are also highly efficient and cost-effective, but natural gas heaters require a gas line to be installed, propane heaters require a propane tank to be installed.

If you are reading this then stop everything and give those folks a call, they are the best.

I had my AC installed, along with two of my neighbours, and we couldn’t have asked for more,  these guys know what they’re doing, no BS, no hard selling, they offer you exactly what you need and what works for you.

They are well experienced in their field, nibbling on their market share, very very competitive pricing, the big companies actually use them to subcontract their jobs when they charge you extra.

Seriously don’t hesitate, go with Ivan and the AirForce crew.

Mohd A

Over the past 10 years we’ve had 2 furnaces and an AC unit installed with some maintenance in between for both our home and rental property.

Ivan is honest, responsive, extremely reasonably priced and dependable. There is no other company I trust. I have referred Ivan to family and friends and he has quickly become their go-to for all heating and AC needs.

Thanks for the great quality and service.

Our furnace broke down during a cold snap and we called a few companies to see if they could come for an assessment.

The first company that came by (I won’t name) quoted us a pretty steep price for a furnace+install. Air Force was able to beat their price and went above and beyond by working an extra long day to ensure the install was done immediately as to not leave our house freezing cold during the cold snap.

Ivan and Nick were very professional and knowledgeable. The install was done without issue and our new furnace has kept our house nice and warm.

I highly recommend Air Force for any heating or A/C work your home may need. These guys are pros!!


This company installed my A/ C unit, very competitive price. Excellent job was made. Clean job, they used carpet protection in all areas to avoid dust and mesh. After 3 months installation the unit works perfectly, happy to choose this company, highly recommended.
