How does an Intergas manage with fewer parts than other combis?

Its heat exchanger deals with heating and hot water together, so it needs neither the separate diverter valve nor the second exchanger found in an ordinary combi. On other makes those two parts fail more often than most, so taking them out removes a large share of the usual repairs.

Is it difficult to find an engineer who knows Intergas?

You see fewer of them in London than the big-selling makes, so not every engineer works on them often. The design is simpler rather than more complex, but it is not the same. Ninja Plumbers works on them, and when we diagnose the fault we will say if a part needs ordering.

Does an Intergas still need a yearly service?

Yes. Less wears out, but the combustion, flue, seals and condensate trap all still need checking, and the warranty usually relies on it.

Can you repair and service my Intergas boiler?

Yes. Our gas work is done by Gas Safe registered engineers, as the law requires for any gas boiler, whatever the make.

The make

Intergas boilers

An Intergas is a different kind of combi, not just another badge. Its design has no diverter valve and no plate heat exchanger, two parts behind many of the breakdowns on ordinary combis. With less to move, it suffers fewer of the faults that take up most of Ninja Plumbers’ time on other makes. You see them less often in London than the big-selling makes, yet owners have usually picked one deliberately and can tell you why.

The Intergas range

Intergas is a Dutch manufacturer based in Coevorden, best known in the UK for combis such as the Combi Compact HRE and Xclusive. Most combis have a separate plate heat exchanger for hot water and a diverter valve switching between heating and hot water. In an Intergas the main heat exchanger does both jobs, with two separate water circuits built into it. Hybrid options with a heat pump are offered too.

Faults we often find on Intergas boilers

Much less mechanical failure than an ordinary combi of similar age
Faults that lie in the controls, sensors or system more than the boiler
Parts carried less often, so some have to be ordered
Dirty water from an old heating system wearing a newer boiler
Boilers written off by engineers who did not know the design

This list reflects what Ninja Plumbers finds across Intergas boilers in general. It is not a diagnosis of yours, and we confirm any fault on site before giving a price.

Intergas servicing

An Intergas warranty usually depends on a yearly service, so check your warranty terms, which vary with the model and the installer. Because hot water runs through the main heat exchanger rather than a separate plate, limescale in hard London water still matters, and scale protection on the mains is worth having. So is clean heating water, with inhibitor and a filter.

Repair it or replace it?

An Intergas fault is usually worth repairing: there is less to go wrong, and the parts that fail — a sensor, fan, pump or the controls — are modest next to the price of a new boiler. Replacement makes sense when the main heat exchanger fails outside warranty on an older unit. If someone unfamiliar with the design wants to condemn a working one, get a second opinion.
