Our scoreNot reviewed yetSCORE7.0 / 10
Our takeThe MHU50 one size up for a large or leaky building: 64,000 BTU/h output. In an insulated two- or three-car garage it's more than you need and cycles.50% more heat than the CZ220 with a 45-95°F digital thermostat, remote and timer. Its LOW is still 6,250 W, so in a smaller garage it mostly cycles at near full power, and it needs a 40 A circuit.
