Air Source Heat Pumps in Clapham, London
Better Gas Plumbing & Heating helps Clapham, London homeowners plan air source heat pump conversions around the real performance of their property. The assessment can cover heat loss, radiator output, loft and extension areas, hot-water demand, outdoor-unit location and controls so the final heating system is designed as one connected upgrade.

Clapham family homes often reveal their weak rooms before the boiler itself fails
Cold loft rooms, rear extensions that take longer to warm and uneven radiator performance are common reasons homeowners begin reviewing the wider heating system. Those existing comfort patterns provide useful evidence when assessing a future heat pump.
Better Gas can investigate where the current system struggles and compare those rooms with the property’s likely heat demand at lower flow temperatures. This turns familiar comfort problems into practical design inputs rather than carrying them unchanged into the new installation.

Air source heat pump assessment for Clapham houses and renovations
Services can include property suitability review, radiator and underfloor-heating checks, outdoor-unit siting, hot-water planning, control strategy and integration with the wet heating system. Better Gas can also recommend targeted improvements where specific rooms or circuits would otherwise restrict lower-temperature operation.
— How We Work
A Considered Approach to Heat Pump Systems
Heat pumps perform best when the system is assessed as a whole. We consider the unit, heating circuit, controls and property requirements before recommending work.

— Why better gas
Existing cold spots are investigated instead of being masked by a larger heat source
If one Clapham room is difficult to heat today, increasing overall system capacity is not automatically the right solution. The cause may be emitter size, heat loss, circulation or controls. Better Gas can examine those factors and direct upgrades to the weak area, helping the future heat pump serve a balanced system rather than compensate for unresolved local problems.
— The Right ahsp Solution
Why radiator output should be checked room by room rather than from total house capacity
A home can have enough total radiator surface area while still having one or two rooms with insufficient output. Lower-temperature operation makes those local mismatches more visible because each emitter has less temperature difference available to release heat.
Better Gas can compare room demand and emitter capability during a Clapham assessment. Where changes are needed, they can be concentrated on the rooms that genuinely require more output instead of replacing a complete set of functioning radiators.
