The THERM 55/Z indirect heating storage tank is constructed as a wall-mounted storage tank installed on the hanging bar mounted with the boiler on the wall using dowels. Storage tanks of this type are made of resistant stainless steel. An anode bar is mounted on the flange on the bottom of the tank.

Through their construction and the number of available options, THERM storage tank water heaters provide economical preparation of water via energy from an external source. They are recommended for interior locations.
