You can also use a patio heater in a garage. The installation cost depends on the type of heater you’re willing to get, the materials, and the labor cost.

What Are The Cost Factors?

The overall installation cost of a car garage heater is determined by some factors.

What Kind Of Fuel Does It Use?

Electric and infrared heaters are significantly less expensive than natural gas and propane heaters.


British Thermal Units, or BTU, are a measurement of the power of heaters. The bigger the garage is, the more BTUs are required for it. Prices and maintenance rise sharply when you get a heater with more BTUs. A standard one-car garage requires a 30,000 BTU heater, which costs $0.28 to $0.80 to run depending on its type.

Installation Cost

Some heaters require professional HVAC professionals and need venting. This adds to the total cost. You might also need to set up ducts and fuel lines for your garage, which will lead to more costs.

Natural Gas Powered Heater Installation Cost
