The storage tank is a twin layer structure made entirely from plastic. The space between the inside and outside container has excellent foam heat insulation. This extreme heat insulation ensures low overall heat losses for the ROTEX GCU compact
Energy saving: The improved storage tank and cover insulation made from PU rigid foam reduces the heat losses to an absolute minimum. This protects the environment and your wallet.
Low scaling: On commissioning, the storage tank is filled with tap water which is not exchanged during operation. Thus, only the lime contained in this water can be deposited; all the heat exchanger pipes remain free of limescale, as does the electric immersion heater, which is available as an option. On the inner surface of the heat exchanger pipes, the high flow speed when the water is removed releases smaller scale deposits.
Long-life and safe: The materials used (plastic and stainless steel) ensure the ROTEX thermal store has a particularly long life and will provide you with hygienic hot water for decades.
