Standing, certified steel tank with ceramic enamel coating for domestic hot water heating and storage. The internal protection of the tank is provided by a high-quality ceramic enamel coating fired at 830–850°C. The insulation is made of hard polyurethane foam, with PVC (SKAY) coating. About cathode protection in storage magnesium anode is provided.

Indirectly heated storage is suitable for the production of domestic hot water, the parallel internal coils (heat exchangers) could connected outside the tank, in this way it could heated by heat pumps, boilers, heated buffer tanks or solar thermal systems. The large surface area of heat exchanger (in case of connected coils) gives an efficient hot water solution to low temperature heating source
(heat-pump, condensing boiler, etc.) with low pressure drop. The tank has a cleaning flange on which it can be made the periodic maintenance.

The internal heat exchangers of the BSH-P series is fixed (welded) coils which are enamelled together with the tank.

The maximum permissible operating pressure of the tank is 8 bar, the heat exchanger can be used with a maximum pressure of 10 bar. It is maximum operating temperature under pressure 95°C.
