The Intergas Xtreme uses the proven concept of the double aluminum two-in-one heat exchanger. The patented Intergas design, with two separate copper circuits, ensures optimum heat transfer and minimal heat loss. The central heating water and cold tap water flow directly through the heat exchanger, so that the flue gases cool down and the condensation heat is optimally utilized. In addition to this tried and tested heat exchanger, a second heat exchanger (Flue Gas Heat Recovery (FGHR) unit) is used in the Intergas Xtreme. This 2nd heat exchanger is integrated in the flue gas outlet of the appliance with which the combustion gases are further cooled down. The residual heat from the flue gases is also used during heating operation to preheat the tap water. This means less energy is needed to bring the water to temperature.
