Air Source Heat Pumps in Islington, London
Better Gas Plumbing & Heating helps Islington, London property owners evaluate air source heat pumps with a whole-house approach to heating. The assessment considers building heat loss, radiator capacity, domestic hot-water demand, control zones and outdoor-unit location so the proposed system is matched to how the property is actually occupied.

Converted and extended Islington homes need room-by-room thinking
Islington’s terraces and converted houses are often divided, extended or remodelled over time. A single property can therefore contain very different room volumes, insulation standards and emitter sizes, making a simple floor-area estimate a weak basis for heat-pump planning.
Better Gas looks for these variations during the initial review. By understanding the rooms that lose heat fastest and how the existing circuits serve them, the system design can focus on the real peak demand instead of applying the same assumption throughout the building.

Heat-pump assessment, emitter checks and hot-water planning in Islington
Better Gas can assess air source heat pump suitability, review radiators and underfloor heating, consider cylinder requirements, advise on control arrangements and evaluate practical outdoor-unit positions. Where a property needs preparatory work, the recommendations can incorporate targeted heating or plumbing improvements before installation.
— 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
Detailed system knowledge is valuable in homes that have changed layout several times
An Islington heating system may still contain pipework and emitters from earlier room layouts, even after walls have moved or living spaces have been opened up. Better Gas can trace how the current system serves the property and identify where those historic decisions now create limitations. This allows the heat-pump proposal to respond to the present-day building rather than simply inheriting the assumptions of an older boiler installation.
— The Right ahsp Solution
Why open-plan rooms can alter emitter sizing on a heat-pump conversion
Removing internal walls can create larger spaces with more external surface area and different patterns of heat loss. The radiator that once served one enclosed room may no longer be appropriate for the combined space, particularly at lower water temperatures.
Better Gas can assess the finished Islington layout and compare emitter output with the room’s estimated demand. Where an upgrade is needed, it can be directed to the specific space instead of triggering blanket radiator replacement across the property.
