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.
For a garage you heat often: a published 45-135°F thermostat, field-set wattage, a published 208V rating and 5-year element coverage. Owners report it cycling every minute or two, and everything but the elements carries 1 year from installation.

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.
Warranty is void if supply voltage runs more than 5% over nameplate or the heater is improperly wired. Not for drywall or paint dry-out; the dust damages the heater.
