This external hot tub heater is suitable for hot tubs up to 6.56 ft (200 cm). The stove is equipped with a 6.56 ft (2 meter) long chimney. The chimney consists of two parts.
The water circulates between the stove and the tub using the principal of thermosiphon (the movement created by rising hot water). This eliminates the need for a circulating pump or electricity.

The stove is made of high quality marine aluminum. The thermal conductivity of aluminum is about 15 times better than the stoves made of stainless steel and therefore our stoves are up to 30% more effective.
The material is ca 0.12 inches (3 mm) thick, which is two times more than in case of regular furnaces made of stainless steel. And of course, aluminum furnace is 30% lighter. Aluminum furnaces have longer useful life than furnaces made of stainless steel. The aluminium heaters retain their shape for a long time. Heaters made from thin stainless steel may become crooked.
High-quality MIG welding ensures the perfect end result. We check and test impermeability of all welded seams.
It’s strictly forbidden to start the heating before the hot tub is not filled with water.
The pipes which connect the hot tub and the stove must be under the water before it’s allowed to start the heating. Otherwise the stove will be damaged.
The stove has also a small water tap under it and in winter time when the temperature is already -1 degree you should empty your stove as well after bathing, otherwise the water may freeze and this may damage the stove.
