The Boiler models are designed for rooms which do not have warm water supplement or electricity for connecting an electric boiler. Boiler stoves can be connected to a separate water tank. The sauna stove boiler is equipped with a glass door to give a special feeling of the wood burning process. The opening direction of the door can be changed by making these stoves even easier to use. The adjustable legs make it easy to install the stove in a straight position despite floor inclination.
