I have owned my Kuuma Vaporfire 100 for 2 years now. It has failed to provide any heat for our home. I believe it is not the furnaces fault but the installer. Daryl at Kuuma has been great and we both believe it is an HVAC issue. Does anyone live in the Milwaukee area that knows a knowledgeable HVAC company that could asssit in getting this great wood furnace to heat our home.
