Chelsea residents often notice HIU problems first through changes in hot-water response or room comfort
In modern Chelsea developments, the HIU may sit quietly in a utility cupboard until showers take longer to heat, water temperature varies under use or rooms no longer reach their set temperature. Those symptoms can arise from different parts of the unit, the apartment circuit or the communal primary supply, so the first job is to establish a reliable technical picture.
Better Gas checks the operating condition of the HIU and the way it responds to demand. Where appropriate, the engineer can inspect temperature behaviour, valves, controls, strainers and heat transfer, then explain whether the evidence supports a local repair or suggests that the managing agent should also review the building network.

Practical HIU servicing for Chelsea apartments and managed developments
Better Gas can investigate loss of heating, slow or unstable domestic hot water, unusual HIU noise, leaks, control problems and poor heat transfer. Service work may include functional checks, cleaning accessible strainers, examining control valves and actuators, assessing heat-exchanger behaviour, checking sensors and reviewing apartment heating circulation before a repair or replacement decision is made.
— 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
The diagnosis is tied to the actual symptom rather than a generic parts list
HIUs vary by manufacturer, control arrangement and building design. Better Gas does not assume that a familiar symptom has the same cause in every Chelsea property. The team follows the behaviour of the system, considers recent changes within the apartment and checks the components relevant to the reported fault. This keeps recommendations proportionate and is particularly useful in premium managed buildings where access windows and disruption need to be planned carefully.
— The Right HIU Solution
Why an HIU can produce hot water but still struggle to heat the apartment properly
Domestic hot water and space heating use the same communal energy source but are controlled through different operating paths inside many HIUs. A unit can therefore appear healthy at a tap while a valve, control signal, circulation issue or downstream restriction prevents the heating circuit from performing as expected.
For Chelsea properties, Better Gas can compare the unit’s response in each mode rather than judging performance from one quick test. That makes it easier to narrow the fault and avoids overlooking apartment-side issues such as controls, radiator valves or circulation conditions.
