Intergas Heating

Intergas has been at the forefront of domestic boiler manufacture in the Netherlands for over 40 years; its roots, however, go back to 1939, when it was involved in domestic products of quite a different kind. Then the company was known as Machinefabriek van de Wetering and it specialised in manufacturing wooden washtubs and laundry wringers. With the discovery of natural gas in the Northern part of the Netherlands, the company moved to Coevorden in 1961 and, in the mid-sixties, produced its first heating products. In 1989 Intergas launched its first condensing boiler in the Netherlands. This was the first country to take the energy efficiency credentials of boilers seriously and this propelled Intergas into pole position, becoming the leading brand in condensing boiler technology.

Two-in-one heat exchanger

The invention of the two-in-one Double High Efficiency heat exchanger in 1996 revolutionised boiler technology. Now, for the first time, a combination high efficiency boiler with significantly fewer components than any other product on the market, was available. Its innovative design eliminated the need for a secondary domestic hot water plate heat exchanger, diverter valve and auto-air vent, all significant sources of possible future component failure. Moreover, thanks to this technology high-efficiency was combined in both domestic hot water and central heating modes. The energy conscious approach to the Intergas boiler design continues to help households save energy savings and money. The two-in-one heat exchanger is produced in factories in Germany and the Netherlands to Intergas’s exacting standards. The unrivalled reliability is covered by a 10 year warranty.

The flexibility of the Intergas HRE boiler has another major advantage. It is possible to install the hot water system first and connect the central heating system later keeping the  inconvenience of a boiler change to the absolute minimum. And, due to the unique design of the Intergas heat exchanger, the homeowner will still have hot water even if the pump fails.
