2 years extra warranty with the Intergas System Filter

Please note that to fit the boiler you must choose and add either the Fitting Kit A or Fitting Kit B.


Intergas is a pioneer in the field of high-efficiency (HE) central heating engineering. For over twenty years now, Intergas has been dedicated to perfecting its HE boilers. The Intergas Combi Compact HR has been a best selling HE boiler in the Netherlands for many years. Its unique double HE technology was a major breakthrough at the time. It is no wonder that the double high efficiency technology forms the basis for the latest generation of HE boilers - the Combi Compact ECO RF.

A combi or combination boiler 'combines' a high-efficiency water heater with a central heating boiler in one compact unit. With no need for a hot water cylinder in the loft as hot water is supplied directly from within the unit, a combi is ideal for a flat or bungalow with little or no roof space and homes with a loft conversion. And because it delivers endless hot water straight to your taps or shower, it only heats the water as you need it, helping save on hot water costs.

The Intergas Combi Compact ECO RF wall mounted, gas fired boiler is a modulating high efficiency boiler. This means the power is adjusted in line with the desired heat requirements. The aluminium heat exchanger comprises of two separate copper circuits. As a result of the separately constructed circuits for CH and DHW the heating and hot water supply can operate independently of each other. The hot water supply takes priority over the heating. The two systems cannot operate simultaneously.

The appliance is equipped with an electronic boiler controller which, each time heat is requested from the heating or the hot water supply , starts the fan, opens the gas valve, ignites the burner and continuously monitors and controls the flame, depending on the requested output.

By setting a parameter the boiler can be set to operate either on domestic hot water only, heating only or DHW and heating. It is possible to use the boiler's DHW circuit without needing to connect and fill the central heating system.

The secret of the energy efficient design of the Combi Compact ECO RF boilers lies in the unique patented double two-in-one heat exchanger, which ensures the reduction of heat losses and an optimum transfer of heat. The unsurpassed high-efficiency of the Intergas Combi Compact ECO RF ensures economical operation, year after year.

The double two-in-one heat exchanger of the Intergas Combi Compact ECO RF high-efficiency boiler has over a period of more than 10 years proven to be extremely reliable. Due to the separate central heating and hot water circuits there is no need for using a diverter valve and secondary domestic hot water plate heat exchanger. This eliminates a significant source of possible future component failures. Less parts means more reliability!

Using an Intergas Combi Compact ECO RF high-efficiency boiler means you are contributing to caring for the environment. Thanks to the economical operation of the Intergas boiler a considerable saving in energy consumption is achieved. A switch-mode power supply reduces the so called stand-by losses to almost zero. Not surprisingly all Intergas Combi Compact ECO RF boilers have been given a SEDBUK A rating, the highest efficiency band available.

The Combi Compact ECO RF is fitted as standard with an RF module for remote control and direct communications via Honeywells wireless room thermostats. A speparate transmitter is no longer required. Compatible models: Honeywell DTS92 / Honeywell CMS927

The Combi Compact ECO RF is a forerunner in the Netherlands in terms of tap efficiency. The ECO's hot water tap efficiency is over 101%. It can justifiably be claimed that the ECO RF is one of the most efficient HE boilers available. It reduces CO2 emission levels to an absolute minimum and provides maximum savings on heating costs. All in all, it's good for the enviroment and kind to your wallet.

Use of vacuum insulation reduces heat and energy losses to an absolute minimum and ensures whisper-quiet operation year in, year out.

Unprecedented performance levels have been achieved using a new type of heating labyrinth. Water is heated directly within the heat exchanger's copper circuits ensuring optimal heat transfer.

All ECO RF appliances have been fitted with a new, ultra-efficient A-label pumps ahead of new energy legislation taking effect in 2015. These halve the boilers' electricity consumption.
