Should I insulate my garage before adding a heater?

Yes — insulating is the single best investment for garage heating. An insulated garage door kit costs $50-100 and can reduce heat loss by 40%. Wall and ceiling insulation further reduces the wattage needed. You'll spend less on electricity and reach comfortable temperatures faster.

Is it safe to use an electric garage heater around flammable materials?

Electric heaters are safer than gas heaters for garages since there's no open flame or carbon monoxide. However, keep all heaters at least 3 feet from flammable materials, paint, solvents, and gasoline. Ceiling-mounted heaters are safest since they're above floor-level fumes.
