How to Estimate Garage Heater Installation
Contractor method for pricing the unit, labor and hookups to heat a garage.
A garage heater bid is the unit, the install labor and the hookups. The fuel type decides whether you add electrical work, gas line and venting.
THE SHORT ANSWER
How do you estimate garage heater installation?
Add the unit, labor and hookups for the chosen fuel. A gas heater for a 440 sq ft garage with a 9 ft ceiling runs $2,100 at the defaults and sizes near 24,750 BTU as a preliminary allowance.
Size the heater
Use both floor area and ceiling height for a preliminary output allowance. A 440 sq ft garage with a 9 ft ceiling returns about 24,750 BTU; climate and insulation still require a proper heat-loss check.
Pick the fuel type
Electric units are simpler but cost more to run; gas units need venting and possibly a gas line; infrared heats objects directly.

Add hookups
An electric unit needs a dedicated circuit. A gas unit needs combustion venting and a gas line if none exists.
Total and validate
$800 unit + $400 labor + $400 electrical + $500 venting totals $2,100. Use the Garage Heater Installation Cost Calculator.
