Value in a garage heater means the most useful heat and the longest service life for the money, not just the lowest sticker. For most one- and two-car garages that points to a 5000-watt, 240-volt unit heater: it warms roughly 400 to 600 square feet, mounts out of the way and runs for years. We scored four of the best-value 5000W models side by side.
We compared heat output, build, controls and safety features using manufacturer specifications and owner feedback, then scored each heater out of 10; our Editorial Policy explains how we choose. For more picks see the best value space heater for garage and best budget space heater for garage guides. Hardwired 240V heaters must be installed by a licensed electrician on the right breaker and wire size. Keep any heater at least 3 feet from gasoline, paint, solvents and sawdust, and never leave it running unattended.
