SUNEX Indirect Water Heater FISH S2 X 200 to 500 Liters 2x Efficient Heat Exchangers

Domestic hot water tank - Domestic hot water storage tank in 200, 300, 400 and 500 liter volumes

Standing domestic hot water tanks for domestic hot water preparation. The hot water contact surface with the tank is protected against corrosion by a layer of high-quality enamel and a magnesium anode*. This ensures, in accordance with DIN 4753, that the domestic hot water only comes into contact with a hygienically clean surface.

Domestic hot water is heated by two independently operating smooth-tube water heat exchangers, which allow the connection of an external heat source such as a solar system, heat pump, boiler or optional electric heating element.

Thermal insulation

The thermal insulation in the tanks consists of a layer of CFC-free polyurethane rigid foam and a replaceable layer of PVC jacket.

Standard equipment

Inspection opening, thermometer, sleeve for electric heating element, magnesium anode*, 2x internal heat exchangers.

*A titanium anode can be used optionally.
