How much does a ceiling-mounted radiant tube heater cost for a three-car garage in Ottawa?

A ceiling-mounted radiant tube heater for a three-car garage in Ottawa typically costs $2,500 to $5,000 installed, depending on the BTU capacity needed and whether you choose a single large unit or multiple smaller units. For a standard three-car garage (approximately 900 to 1,200 square feet), you'll likely need 45,000 to 75,000 BTU capacity to handle Ottawa's extreme winter temperatures effectively.

Radiant tube heaters are an excellent choice for larger Ottawa garages because they heat objects and people directly rather than trying to warm all the air in the space. This makes them particularly efficient in drafty or uninsulated garages where traditional forced-air heaters struggle. The radiant heat feels comfortable even when the ambient air temperature is cool, and these units reach full heat output within minutes rather than the 20-30 minutes required for a space to warm up with conventional heaters.

For a three-car garage, you have two main options: a single 60,000-75,000 BTU unit ($1,800 to $3,200 for the heater plus $700 to $1,200 installation) or two smaller 30,000-40,000 BTU units ($1,200 to $2,000 each plus $500 to $800 installation per unit). Multiple smaller units provide more even heat distribution and allow you to heat only the section of the garage you're using. Popular models include Modine Hot Dawg and Reznor units, both engineered for Canadian conditions.

Installation requires a licensed gas technician and electrical connections for the blower motor and controls. The units mount 8-10 feet above floor level and need proper venting through the roof or wall. Factor in $300 to $600 for gas line extension if your garage doesn't already have natural gas service. These heaters work exceptionally well in Ottawa's climate and can maintain comfortable working temperatures even when it's -30°C outside.
