I have read most of the post about the Blaze King stoves but I have one question that I haven't seen addressed yet. My current stove has a listed BTU max output of 72,000 btu's with a 2.3 liter firebox. On the coldest days I need to run that sucker very hot to keep up with the heat loss in my house so i suppose i'm kicking out 65,000 + btus for maybe 40 to 60 minutes at the hottest part of the burn then substantially lower Btus output after that. The Ashford 30 or Sirrocco 30 both list a Btu output of 36,000 on High for 10 hours. I guess my question is would the constant output of the Blaze Kings on high be able to keep up with the coldest days. Anybody have a similar stove and then replaced it with a Blaze King and was it able to keep up with the really cold weather? Thanks
