All stainless steels have a high resistance to corrosion. Low alloyed grades resist corrosion in atmospheric conditions; highly alloyed grades can resist corrosion in most acids, alkaline solutions, and chloride bearing environments, even at elevated temperatures and pressures.
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.
