buffer tank with two heat exchangers Fish S11 X
Water tanks
Buffer tanks
Upright buffer storage tanks for all types of heating systems with solid fuel, oil, gas, heat pump or electric boilers. The storage tanks are equipped with large, efficient heat exchangers that allow a solar system and an additional heat source to be connected directly (without using additional heat exchangers). A large number of connections allows the storage tank to be used in atypical heating systems and the combination of storage tanks to form batteries, which allows the total capacity to be adapted to individual needs.
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.
