We moved into our house 2 years ago and inherited a nice harman stove with it. However, the stove is located in the basement and is used to heat the first floor (basement door is a half door to allow heat to come up stairwell) which has worked quite well but there is insulation below the subfloor which I'm wondering if I should remove or not. Will it make much of a difference in heating the floor above or am I better off just leaving it?
