Frequently asked questions
How do I size garage heaters?
Use garage volume, insulation, climate and desired temperature rise rather than square footage alone. Manufacturer sizing guidance is the starting point.
Electric or fuel-fired heat?
Electric avoids combustion exhaust at the heater but can require substantial circuit capacity. Fuel-fired heaters add combustion, ventilation and fuel considerations.
Can I use a propane heater in a closed garage?
Combustion heaters can create carbon monoxide and other hazards. Use only as explicitly permitted by the manufacturer with required ventilation and clearances.
What electrical requirements matter?
Large electric garage heaters may require dedicated 240-V circuits and permanent wiring. Follow the heater instructions and applicable electrical code.
Where should a garage heater be mounted?
Maintain manufacturer-required clearances from vehicles, combustibles, work areas and ceilings/walls.
Is infrared heat different from forced air?
Infrared primarily heats people and surfaces in its path, while forced air heats and circulates room air. The better choice depends on how the shop is used.
What is the biggest sizing mistake?
Ignoring insulation and air leakage. A high-output heater can still struggle in a drafty, poorly insulated space.
