buffer tank without heat exchanger Fish S4 X
Water tanks
Buffer tanks
Buffer tank in vertical design. Ideal for all types of heating systems with solid fuel boilers, oil, gas, heat pumps or electric boilers. By using an additional heat exchanger, it is possible to support the heating system with a solar system. A large number of connection openings enable the use of the tank in non-conventional heating systems. Connecting tanks in batteries makes it possible to adapt the total capacity to individual needs. Buffer tanks can be used to store cooling water at a temperature of 7 to 12 °C*.
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.
