HIU repair for Intatec, Oventrop, Kamo/KVM, Switch & hiu brands
Most HIU companies stop at the three or four biggest names. We don't. If your Heat Interface Unit is a less common brand, it still gets the same specialist diagnosis, the same checks on valves, sensors, controls and heat exchange, whatever badge is on the front panel.
Brands we cover beyond the big three
Alongside Danfoss, Caleffi and Evinox, we regularly work on the following manufacturers and others not listed here.
A cold tap or radiator can have several causes. We establish what the HIU is being asked to do, what it is receiving from the heat network and how each control component responds.
TECHNICAL FAULT FINDING
We test the system.
Not just the symptom.
Evidence before replacement
Temperatures · pressures · flow rates · valve response
No heating or hot water
We test primary supply, demand controls and domestic hot water response before replacing parts.
Low pressure or flow
Differential pressure, strainers, PICVs and flow rates are checked as one connected system.
Unstable temperatures
We assess sensors, control valves, actuators and return temperatures under live demand.
Metering & control faults
Heat meters, prepayment interfaces and control communication are tested methodically.
How it works
01
Tell us the brand
Call, WhatsApp or send a photo of the unit's data plate if you're unsure.
02
We confirm we can help
We check we cover the brand and, where needed, source the right parts.
03
Diagnose the HIU
Our engineer investigates the underlying fault, not just the symptom.
04
Complete the work
We carry out the agreed repair or service and confirm everything's running.
