Triple Energy

Triple-energy systems have a cylinder with two heat exchangers. The lower one is connected to the solar collectors on the roof, the upper one to the central heating boiler or heat pump, and the electric immersion heater remains as a third source. The sun covers as much as it can, and the heating tops up only what is missing.

This is the usual choice for homes with central heating, apartment buildings, hotels and businesses with steady hot water demand. Available with a red or blue cylinder of 150 to 1000 litres (blue in 150, 200, 300 and 1000 litres) and a pre-assembled kit.
