Buy on AmazonOur verdict
The Buddy is propane, needs no electricity, and throws 9,000 BTU of radiant heat anywhere — with the ventilation and CO-alarm rules that come with burning fuel indoors. The King is a 240V electric heater that's safe to run in a closed garage all day and holds a thermostat, but it needs a 240V outlet. Intermittent sessions, job sites, outages, and cabins: Buddy. A garage you heat regularly and safely with the door shut: King.
Pick the Mr. Heater if…
- ✓No 240V outlet, or no power at all
- ✓Intermittent use: a couple of hours a week, job sites, ice fishing, outages
- ✓You'll always crack a window and run a CO alarm
Pick the King Electric if…
- ✓Regular use in a closed garage or shop
- ✓You want a thermostat and no combustion indoors
- ✓A 240V outlet is available
