Hot water tank with two high-performance heat exchangers with large heating surface Fish S16 X
Water tanks
Hot water tanks for heat pumps
Domestic water storage tank in a standing design for hot water preparation. The storage tank has 2 large-surface heat exchangers, the upper one for a heat pump and the lower one is designed for a solar system or a boiler. The contact surface of the hot water storage tank is protected against corrosion with a high-quality enamel coating and a magnesium anode*. This ensures, in accordance with DIN 4753, that the domestic water only comes into contact with a hygienically clean surface.
thermal insulation
The thermal insulation in the storage tanks consists of a layer of CFC-free polyurethane rigid foam and a replaceable layer of PVC sheath.
standard equipment
Inspection opening, thermometer, sleeve for electric heating element, magnesium anode*, 2x internal large-area heat exchangers.
*Optionally, a titanium anode can be used.
