Fulham HIU problems can appear gradually rather than as a complete loss of service
Residents may first notice that hot water takes longer to reach temperature, showers become less stable or rooms need more time to warm. Gradual changes like these can indicate restricted flow, a tired actuator, control drift, fouling or another developing issue that is easier to understand when the unit is tested under realistic demand.
Better Gas can review the reported change against the HIU’s actual operation. Rather than waiting for a total failure, the engineer can identify components that are no longer behaving correctly and consider whether the apartment heating circuit is contributing to the symptoms.
— OUR hiu SERVICES
HIU maintenance and repair support for Fulham communal-heating systems
Work can include diagnostic testing, domestic hot-water checks, heating-mode assessment, control and sensor review, valve and actuator inspection, accessible strainer cleaning, leak investigation and heat-exchanger performance checks. Where the system has become unreliable over time, Better Gas can also discuss whether targeted repair or planned HIU replacement is the more sensible route.
— 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
Better Gas looks for developing performance problems before defaulting to full unit replacement
A poorly performing HIU does not always need to be replaced. Better Gas combines practical heating experience with component-level diagnosis so Fulham clients can understand what is actually failing and what remains serviceable. That can be particularly valuable for landlords and managing agents trying to plan maintenance expenditure across apartments without turning every complaint into a major replacement project.
— The Right HIU Solution
Why strainers and flow restrictions can affect both comfort and heat transfer
HIUs depend on adequate flow through relatively compact components. Debris or restriction at a strainer can reduce the energy available to the plate heat exchanger or heating circuit, sometimes producing symptoms that resemble a failing valve or undersized unit.
In Fulham apartments, Better Gas can include flow-related checks as part of a wider diagnosis instead of focusing only on electronic controls. The aim is to build evidence from several operating conditions so the repair addresses the cause rather than just the most obvious symptom.
