Our take
A fixed vent-free heater that adds the thermostat and blower the Big Buddy lacks, for a cabin you heat all winter. It's an installed heater, so its own manual sets the fuel supply, room size and venting rules.
Our default for a one- or two-car garage heated in sessions: 5,000 W with 4,000 and 3,000 W steps, hung from a joist. The knob thermostat has no published range, and like every electric heater here it can't share the garage with gas cans or paint.

Watch out for
We haven't read this heater's manual; check its room-size and ventilation limits before you buy. Never run an unvented fuel-burning heater in a room where people sleep (CPSC). The low-oxygen shutoff does not detect carbon monoxide; run a battery CO alarm listed to UL 2034 wherever the heater runs.
1-year warranty; after 30 days the heater ships to World and Main freight prepaid. One amp figure covers 208-240V; on 208V the heater makes less heat, and Comfort Zone doesn't publish how much.
