Components - pro solar Duo tank
The combined buffer storage tank with integrated domestic water heater
The Duo-tank combines the benefits of a large buffer storage tank with those of demand-oriented, constantly freshly heated domestic water. A 750 or 950 litre buffer volume, with 250 litres of this as a hot water reserve, allows optimised use of the boiler and solar energy system. The straigth-tube heat exchanger fitted in the lower storage region makes the solar circulation child´s play. |
