We purchased a Hearthstone soapstone in 1998 and used to heat our 1900 sf house. Since then we have moved to TN and have the stove in our new house. It just does seem to heat the living area as well as when we first got it. Is there something that we could check, replace in the stove? Could we have damaged somthing internally when moving it? We tried to be very careful with it, but one never knows. Any suggestions that you could give us is greatly appreciated.
