Our take on the Mr. Heater Convection MH80CVX

The Mr. Heater MH80CVX is a portable propane convection heater rated for indoor use, sized for roughly 800 square feet. It works without electricity, so it suits garages, workshops, cabins and job sites where power is unreliable. Unlike radiant heaters that warm only what they face, it circulates heated air through convection, so the whole room warms more evenly. It is a simple, sturdy unit with no thermostat, fan or Wi-Fi, and owners treat it as basic, dependable heat rather than a smart appliance.
