The INTERGAS Shop's Intergas Xtreme Review

The Intergas Xtreme 36 is the very latest and most advanced boiler to be launched by Intergas Heating. The Intergas Xtreme 36 forms part of the latest X-Series range of Intergas boilers.

The Intergas Xtreme 36 uses the proven concept of the double aluminium 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 utilised.

In addition to the Intergas tried and tested heat exchanger, a new secondary heat exchanger (Passive Flue Gas Heat Recovery (PFGHR) unit) is used in the Intergas Xtreme. This additional heat exchanger is integrated into the flue gas outlet of the appliance where the combustion flue gases are further cooled down. The residual heat from the flue gases is used during hot water operation to preheat the tap water. This means less energy is needed to bring the hot water to temperature.

All Intergas Xtreme boilers have been fitted with ultra efficient A-rated Wilo pumps and fully comply with ErP energy legislation. This halves the boilers electricity consumption verses older combi boilers. The new Intergas X-Range of boilers use a sleek, touch-screen design for enhanced looks with simple user operation. The use of vacuum panel insulation inside the casing reduces heat and energy losses to an absolute minimum and ensures a whisper quiet operation year-in, year-out.

The Intergas Xtreme is fitted as standard with a Honeywell RF module for remote control and direct communications with Honeywell's wireless room thermostats (CMS927, CMS727 or T87RF) and therefore a separate wireless relay box is not required.
