The Intergas Xtreme combi boiler is a reliable and efficient solution for heating both water and your home. With its modulating burner control, built-in weather-dependent regulator, and energy efficiency class A for both space and water heating, it saves energy and increases comfort in the home.
The Xtreme uses the proven concept of the dual aluminium two-in-one heat exchanger. The patented Intergas design, with two separate copper circuits, ensures optimal heat transfer and minimal heat loss. The second heat exchanger (WTW unit) is integrated into the flue gas outlet of the unit, further cooling the combustion gases. Additionally, the residual heat from the flue gases during central heating operation is used to preheat the domestic hot water.
To prevent damage to the additional heat exchanger in the flue gas tube (the ribbed stainless steel hose), it is advised to install the supplied water hammer arrestor in the hot water line – at least 60 cm from the unit.
All Xtreme units are Hybrid Ready, meaning these units are suitable for expansion into a hybrid heat pump system. This can be achieved immediately upon purchase or at a later stage.
All Xtreme units are standardly equipped with an RF module and fully prepared for the future. This makes it easier to control the heating via smartphone, in combination with the Intergas Gateway, Comfort Touch thermostat, and Comfort Touch app.
This boiler is equipped with an 80/125mm concentric flue gas outlet.
