hey there. we are thinking of switching from a toyo to a pellet stove to heat our 1200 sqf 2 story log house. it's 3 years old and was done in 8 inch logs. i don't know its r rating but it was real tight during our blow test last fall for our inspection. we really want to get away from the oil heat because of the price. we are hearing conflicting things about the compatablity of pellet stoves and our long COLD winters. any words of wisdom out there?? thanks for the help.
