Heat pump installation in Harrow& surrounding areas,designed around your home

A gas boiler heats water to a high temperature quickly. A heat pump works best producing lower-temperature water for longer periods, keeping the home at a steady temperature rather than heating it up in short bursts. This difference is why heat pumps need to be designed as a whole system, not dropped in as a boiler replacement.

A heat loss assessment calculates how much heat each room loses on a cold day. This tells us what size heat pump you need and whether each radiator is big enough at lower flow temperatures. Rooms that fall short may need a larger radiator or underfloor heating.

Insulation makes a large difference. Loft insulation, cavity wall insulation and draught-proofing all reduce how much heat the home needs, which means a smaller, cheaper-to-run heat pump.

The outdoor unit needs a position with good airflow, a solid base and a sensible pipe route into the home. Noise and distance from neighbours are also considered.

Once installed, running a heat pump efficiently usually means leaving it to maintain a steady temperature, rather than switching it on and off. We set up the controls and show you how to get the best from it.

Heat pumps can be connected to existing radiators where they are large enough, to new larger radiators, to underfloor heating, or a mixture of these. Underfloor heating suits heat pumps particularly well because it spreads heat across a large surface at a low water temperature.

Servicing an existing heat pump includes checking the outdoor unit for debris and airflow, cleaning filters and strainers, checking system pressure and controls, and confirming the heat pump is performing as expected. Regular servicing helps it keep running efficiently year after year.

Because we work on gas boilers, cylinders, underfloor heating and controls as well as heat pumps, we can look at your whole heating system and recommend what makes sense for your home and budget.
