Comfort Zone CZ220 Ceiling-Mount Garage Heater Review

A ceiling-mounted unit heater is the cleanest garage heating setup: nothing on the floor to trip over, warm air pushed down across the work area from a corner, and a thermostat that can hold the space at 45–50°F overnight so paint, glue, and car batteries are happy. The CZ220 is the cheapest credible way to get there. It makes 5,000 watts — right for an insulated two-car garage — and comes with the bracket; you supply the 240V circuit and an hour of an electrician's time.

Performance is what the wattage predicts: a cold insulated garage gets to working temperature in an hour, and the thermostat cycles it from there. Aim the louvers down toward the floor at the far end of the space so the warm air has to cross the room before it rises. The fan is loud — it's a shop heater — and the thermostat dial is on the unit, which means you'll either pick a setting and leave it or wire in a line-voltage wall thermostat, which we'd recommend.

What you give up versus the Dr. Infrared DR-966 is a thousand watts of headroom, a low setting, and heavier steel. For a home garage that gets heated evenings and weekends, that's a fair trade for the savings. Keep combustibles well clear of the discharge, follow the clearance numbers in the manual, and have the circuit installed properly — a 240V heater on undersized wiring is a fire, not a heater.
