Dealer being straightforward with me that he will sell me a pellet stove that I planned on putting in the basement with the idea that the heat will rise up to the first floor (and somewhat beyond?) but he says it will not help me and that I will find out I have a nicely heated basement and still a cold house. Basement is 2000 sf as is 1st and 2nd floor. It is an old house with no insulation under the first floor, just the subfloor as far as I can tell. First floor is mostly pumpkin pine boards. The basement walls have foam insulation sprayed on, not sure how long ago. Any thoughts on whether the largest pellet stove he has in stock that supposedly will heat up to 2000 sf will transfer heat to the 1st floor or am I wasting money. Thanks all!
