Trusted HIU & MVHR Engineers Across Enfield
Enfield has one of the most established district heating footprints in north London. The borough's own energy company, Energetik, operates heat networks serving Meridian Water, the Electric Quarter at Ponders End and the Alma Estate — meaning thousands of Enfield flats take their heating and hot water from a communal network through a Heat Interface Unit rather than an individual boiler.
Collide Group provides specialist HIU and MVHR service, repair, installation and powerflush across the whole Enfield borough. Our engineers carry parts for every major HIU brand and resolve most faults on the first visit.

HIU & MVHR Engineering in Enfield — A Local Guide
Enfield is a large north London borough undergoing significant regeneration. Meridian Water is one of the largest regeneration schemes in the capital — a multi-billion-pound programme delivering around 10,000 new homes over the coming decades, served by a district heat network with an HIU in every flat.
Because so much of Enfield's newer housing stock is network-connected, the faults we attend here are typically HIU-specific rather than boiler-related: blocked plate heat exchangers, sticking PICVs, failed actuators and temperature sensors that have drifted out of calibration. Common brands across Enfield buildings include Danfoss, SAV, Switch2 and Caleffi.
Newer Enfield developments are also built to high airtightness standards, which means they rely on MVHR (Mechanical Ventilation with Heat Recovery) for ventilation. We service and repair MVHR units alongside HIUs, which is often more convenient for residents and property managers than booking two separate trades.
