Frequently Asked Questions
What's better — electric or propane garage heater?
Electric is safer (no combustion, no CO risk), cheaper to run if electricity rates are moderate, and requires no fuel storage. Propane heats faster and works without electricity. For most homeowners, a 240V electric unit is the better long-term choice. If your garage has no 240V outlet and you don't want to rewire, a propane or 120V portable is the practical option.
Do I need to hardwire a garage heater?
240V units (7,500W+) must be hardwired by an electrician — they don't plug into standard outlets. 120V units (1,500W max) plug into standard outlets but only heat small spaces effectively. If you're heating a full 2-car garage, hardwired 240V is the right call.
What BTU do I need for a 2-car garage?
A 2-car garage is typically 400-500 sq ft. You need approximately 10,000-15,000 BTU (3,000-4,500W). If the garage is uninsulated, add 50%. The 7,500W units on this page are close to 25,600 BTU equivalent — sufficient for most 2-car garages.
Are ceiling-mounted heaters better than portable?
For permanent garage heating: yes. Ceiling mount keeps the floor clear, distributes heat more evenly via fan-forced convection, and is safer (no tip-over risk). Portable units are fine for occasional use or single-person workspaces. For regular use, ceiling mount is the better investment.
