HIU Services in Kensington, London
Better Gas Plumbing & Heating provides HIU servicing, fault diagnosis and repair for apartments and managed residential properties in Kensington, London. The team investigates heating and domestic hot-water performance at the heat interface unit, checks the apartment-side system and helps determine whether a fault sits within the dwelling or needs escalation to the communal heat-network operator.

Kensington HIU faults need careful separation between apartment equipment and the communal network
Mansion blocks and high-spec apartment developments in Kensington can rely on communal heating systems while each dwelling uses its own HIU to transfer heat into the property. When hot water becomes inconsistent or radiators stop responding, replacing parts without establishing where the fault originates can waste time and leave the underlying problem unresolved.
Better Gas approaches the unit as an interface rather than a standalone boiler. Checks can cover controls, valves, actuators, strainers, plate heat exchangers, temperatures and the downstream heating circuit, with the findings used to distinguish an HIU problem from a wider primary-network or building-side issue.

HIU diagnostics, maintenance and component repairs for Kensington properties
Support can include HIU fault finding, domestic hot-water temperature and flow checks, central-heating diagnosis, control-valve and actuator testing, strainer inspection, heat-exchanger performance checks, sensor and control assessment, leak investigation and replacement planning where repair is no longer economical. Better Gas can also review radiators, thermostatic controls and apartment pipework when symptoms extend beyond the HIU itself.
— How We Work
A Technical Approach to HIU Problems
HIU faults can involve controls, valves, heat exchangers, sensors and the wider heat network. We assess the unit properly before recommending repair or replacement.

— Why better gas
A broader heating background helps avoid treating every HIU symptom as the same fault
Better Gas works across plumbing, heating, gas systems, controls and HIUs, so the engineer can look at what happens before and after the unit rather than focusing on one component in isolation. That matters in Kensington buildings where refurbishment work, altered radiators or changed controls may affect performance inside the apartment even when the communal heat supply is available. Clear diagnosis gives residents and property managers a stronger basis for deciding whether the next action belongs inside the flat or with building management.
— The Right HIU Solution
Why fluctuating hot-water temperature can point to several different HIU components
Unstable domestic hot water is not automatically evidence that the plate heat exchanger needs replacing. Flow conditions, temperature sensors, control valves, actuators, strainers and the available primary-side temperature can all influence how quickly and consistently the HIU transfers heat.
In a Kensington apartment, Better Gas can test the behaviour of the unit under demand and look for evidence that supports a specific repair. This diagnostic approach is more useful than changing expensive parts by assumption, particularly where access, finishes and resident disruption need to be kept under control.
