The SL models are designed for people who want to conveniently heat their sauna from another room or outside the building. The opening direction 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 heating 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 floor inclination.
This heater comes with 90 lbs of genuine Harvia sauna stones.
