The Master MH-18PNCH-A is a portable propane cabinet heater that puts out up to 18,000 BTU and is rated to heat roughly 450 sq. ft. It runs on a standard LP cylinder through the included hose and regulator, needs no electricity, and lights with a piezo igniter. Three dial-selected heat settings and a claimed run time of up to 65 hours on low make it a fit for garages, workshops, job sites and emergency backup heat. Against radiant tank-top and forced-air propane heaters it trades fast spot heat for quieter, gentler cabinet-style convection, and it carries the usual safety package: tip-over shut-off, high-limit shut-off, flame-out fuel cut and a thermocouple.
