Triple Energy

A triple-energy solar water heater also has a heat exchanger (coil) inside the tank that connects to the central heating circuit. In the winter months, while the boiler or heat pump is running, the domestic water is heated from there too, without switching on the electric element.

The Mastersol ECO triple-energy models keep the series' collector and enamelled tank. They need two pipes from the boiler room up to the roof; if your home already has them, replacing an old triple-energy unit is straightforward.
