Win-win
The Xtreme incorporates the tried-and-tested back-to-back two-in-one aluminium heat exchanger. Our patented design, with its fully integrated copper circuits, ensures optimum heat transfer while minimising heat loss. The central heating water and cold tap water flow directly through the heat exchanger, so the flue gases cool to the maximum and as much heat as possible is recovered from the condensate for reuse
The Xtreme also has a built-in flue gas recovery unit at the back of the heat exchanger, which is connected to the flue. It extracts even more excess energy from the condensate and this energy is used to preheat the water for domestic hot water or heating, depending on which mode is being used. This reduces still further the amount of gas needed to reach the required temperature, while lowering both CO2 emissions and energy bills.
