The outdoor wood-burning stove is specially designed and adapted for hot tubs. The water circulates by itself, under the influence of the “thermosiphon” principle. The hot water rises and creates a low pressure that brings up the cold water from below. Therefore, in this case, there is no need for a circulation pump and no electricity, and this allows you to heat the water with an externally installed wood-burning stove. A huge advantage is that it will leave more space in the tub and allow you to choose a smaller tub model.

Both the outer body of the stove and the firebox are made of stainless steel. The frame and doors are made of cast iron. The heat generated by the fire is efficiently transferred to the water through a unique and complex internal structure of the stove, which turns the entire firebox into a heat transfer surface. The total heat release power is equal to 30 kW.
