I love this thing , I have not changed a thing but the new burner and have used half the coal and keped my house at 70 all winter. The only thing I figure is I am at the right btu for my house.sorry I aded a dhw !!!!!!!!!!! I believe I have already paid the $300 it coast , maybe the extara btu's was just right for my house. We had below zero temps for a couple days with wind and this thing acted double the 90 btu burner .Thanks L.L. I am happy ( could u put me on the pay roll??)
