The Master is a portable propane heater that puts out 18,000 BTU and is rated to warm up to 450 square feet. It runs on one-pound propane cylinders and needs no electricity, so it works in a tent, a garage, a deer blind or on a job site. A tip-over switch and an oxygen depletion sensor shut it off if something goes wrong. Against radiant tank-top and patio heaters it trades a wider heat spread for a bulkier body and a steady appetite for small cylinders.
