    We have purchased a Jotul 3 CB. It is a wonderful stove and heats our room easily. But we are concerned about the heat that seems to be radiating to the floor. We are rehabing a 1750 circa farm house. We have had to put a subfloor over the existing wood plank flooring( as it is in very poor condition). We have put DUROCK under the stove in place of the plywood flooring. We are considering a large piece of slate for the "hearth" under this stove. We are not certain this would be within the specifications in the installation guide for our stove. Any information would be appreciated.


    It would be best to put the slate over one or two layers of Durarock. If you want to do an even better job, place a piece of sheet metal against he floor below the cement board. This should be fine for a stove like the 3CB that site fairly high up on legs. The stove also has a built-in bottom heat shield which helps retard downward radiation.

    It is fine for the floor to get nice and warm..there is a BIG difference between warm and too hot. The rule of thumb is that if you can hold your hand on the wood for even a few seconds, it's in an OK range.
