Product Details
The Mr. Heater MH540T 540-Degree Tank Top Heater delivers 30,000 to 45,000 BTU/hr of powerful radiant propane heat, making it a go-to solution for contractors and tradespeople working on job sites, loading docks, and construction sites in cold weather. The 360-degree burner head combined with a 180-degree multi-directional mounting bracket gives you full directional control over heat output, covering up to 1,125 sq. ft.
