Established in The Netherlands in 1939, Intergas Boilers are a manufacturer of high-efficiency gas boilers for domestic use. As the market leader in The Netherlands, Intergas Boilers were a pioneer in the development of the two-in-one heat exchanger.

First utilised by the company in 1996, this continues to be utilised across the Intergas range of boilers and allows them to be more efficient by using less fuel to generate the required heat output than other boilers.

In addition to this, the innovative design of the heat exchanger also prevents possible future component failure by eliminating the need for a secondary domestic hot water plate heat exchanger, diverter valve and auto-air vent.

Today, Intergas are part of Rheem, the largest manufacturer of water heating products in North America. The current Intergas range comprises combi, open vent and regular boilers.
