SL and Building boiler stoves

Ease of use reaches a new level. The SL models are designed for people who want to conveniently heat their sauna from another room or outside the building. The opening di-rection of the door can be changed, making these stoves even easier to use. SL and Boiler stoves provide great bathing in small and medium- sized saunas. Boiler stoves can be connected to a separate water tank.All Harvia stoves for through-the-wall heater and Boiler models are equipped with a glass door to give that special feeling. The adjustable legs in 20-series make it easy to install the stove in a straight position despite fl oor inclination. A properly built sauna room is a very important factor in getting the most out of your woodburning stove. Stove power should be selected on the basis of the size and material of the sauna. One square metre of stone, glass or similar non-insulated surface increases the stove power requirement as much as if the sauna room cubage were increased by 1.2 cubic metres.If the interior wall of the sauna room is non-insulated log, the corre-sponding factor is 1.5. Remember that the walls and ceiling manufacturers in particular need to be very well insulated. You should also pay attention to sauna room building ventilation. Effi cient air circulation ensures that the bathers can enjoy clean air that is easy to breathe.
