Rated 5 out of 5 by 1reviewer.
Rated 5 out of 5 by We have a 40x60 Quonset hut shop. We heated it many years with a 170K BTU torpedo heater and a wood/coal stove. I should have bought the Dayton 4XA50 years ago. On a cold 16 degree morning, this place is 80 degrees within 10 minutes and after the building is warmed up it runs 2x an hour for 5 minutes at a time set on 60 degrees. No more hassle with the wood stove or constant running of the smaller torpedo heater. Unbelievable product. Very pleased. February 11, 2015
