All our stoves are 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 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 drainage 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. With our aluminum heaters we do not recommend to use the chlorine. Regarding other chemicals please make sure it is harmless to the marine aluminum.
