Harvia M3 SL Series 16.5kW Wood Burning Sauna Stove w/ Exterior Feed

If you are looking to get additional uses out of your sauna stove then this Harvia M3 SL is the stove for you. The M3 SL is placed in the sauna room and your firewood is loaded into the fire chamber from the other side of the wall. The M3 SL will give your small or medium sauna great steam.
