Mr Heater Original 540-Degree 45,000 BTU Tank Top Radiant Propane Heater
Review & Specs Analysis
The Editor's Take
The Mr. Heater Original 540-Degree is a highly portable, direct-to-tank propane heater. Its 45,000 BTU output and multi-directional radiant heat are excellent for quickly warming patios, workshops, or garages. The tip-over safety shut-off is a crucial safety feature. While its material isn't specified and dimensions are compact (10.4"W × 10.4"L), making it best for temporary heating needs rather than permanent outdoor decor, its ease of use and powerful output justify its strong user ratings.
