Scotty, I don't know what a Mr Heater is but I use the kind that screws on top the 5 gal. propane tank. I have had it for 5 years and only had to replace the sensor (14.95 at coast to coast hardware) once. It is adjustable, low med. and high, 9,000 - 12,000 btu. I believe I got it at Coast to Coast. Have seen them at other hardware stores, good luck.

Doubletake
