Soapstone wood stove gives off heat for 15 hours

Given the slow rate at which it cools down because of the thermal mass of the soapstone, this will keep you warm all night on a couple of pieces of wood. It is also 83% efficient.

Our cast iron Jotul keeps us warm all night on two pieces of wood. True, 15 hours is a long time… but it should be remembered that the greater thermal mass will take longer to heat up just as it takes longer to cool down.
