HIU Services in Wandsworth, London
Better Gas Plumbing & Heating provides HIU servicing, repair and hot-water/heating diagnostics for Wandsworth, London homes connected to communal energy systems. The service considers how the unit performs under real household demand, which is especially important in larger apartments where simultaneous hot-water use can expose flow or heat-transfer problems.

Wandsworth family apartments can place high short-term demand on domestic hot water
Multiple bathrooms, morning routines and back-to-back showers can reveal HIU performance issues that are not obvious during a brief low-flow tap test. Residents may experience temperature drop-off only when demand increases, making it important to reproduce the conditions under which the complaint actually occurs.
Better Gas can assess domestic hot-water behaviour under demand and then investigate relevant controls, flow paths and heat-transfer components. The engineer can also consider whether the communal supply appears capable of supporting the requested load or whether building-side input is needed.
— OUR hiu SERVICES
HIU servicing focused on real hot-water and heating demand in Wandsworth homes
Services can include domestic hot-water temperature and flow checks, heating-mode testing, actuator and valve inspection, controls and sensor assessment, strainer checks, heat-exchanger review, leak investigation and secondary heating diagnostics. Repair recommendations are based on how the system behaves during use rather than on appearance alone.
— 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
Testing under realistic demand gives a better picture of household HIU performance
Better Gas understands that an HIU may pass a simple static check yet still disappoint when several outlets or a large heating circuit place greater demand on it. In Wandsworth properties, the team can relate the technical checks to the way the household actually uses hot water and heating. This produces a more relevant diagnosis and helps avoid repairs that do not address the resident’s real complaint.
— The Right HIU Solution
Why a hot-water problem may only appear when flow demand increases
At low flow, an HIU may be able to maintain temperature even when a valve, exchanger or primary supply is operating close to its limit. Higher draw-off can expose that limitation because the unit must transfer more energy in a shorter period.
Better Gas can compare low and higher demand conditions during a Wandsworth visit where appropriate. The difference between them can help identify whether the fault is related to heat-transfer capacity, control response, available primary energy or another restriction.
