Does anyone have a masonry heater? I had no idea what they were until someone else mentioned them in another post. Have been surfing a couple of sites and man they are neat. Heat your house from 2 fires a day, I still find that hard to believe. Must have a hard time bringing a cold house up to temp...but they must be the cats a$$ in the spring and fall. Was reading that you must wait 5hrs between fires so as not to overheat the unit. A masonry heater and woodstove would be the ultimate.
