We have 6" insulation all around ,top ,bottom,no basement ( crawl space-insulated ) with 3/4 wood walls inside and out ...

Heater Size

Here is a link to a program which you can download & run to determine the heat loss of your house. I have used it as have others on this board & all have been very happy. It could very well be the best $50 you spend on your new house. I would certainly hope you have more than 6" of insulation in the floor & especially the ceiling.

Hi ralv, what we would all like to have is the smallest furnace we can get by with. The challenge is getting our house to be warm with less. Even though your home was recently built, it is probably less efficient than needed. Air sealing and insulation are easy fixes in many places and they can make your home very comfortable with the furnace you have.
