Specification is what determines performance.

A heat pump sized on a rough estimate will underperform. It runs at higher flow temperatures than it should, cycles inefficiently, and delivers a lower seasonal COP than the same unit installed correctly. That’s why every system we design starts with a proper room-by-room heat loss survey of your property — not a quick estimate based on floor area alone.

Why we install Vaillant

We install Vaillant air source heat pumps and matched Vaillant cylinders. We choose Vaillant for three reasons:

Pedigree. A long-established manufacturer with a genuine track record.

Support. An extensive UK service and parts network, so backup is never in question years down the line.

Range. Vaillant covers a wide spectrum of property types, including units capable of running at higher flow temperatures — meaning older properties with smaller existing radiators can often be heated effectively without a full emitter upgrade.

How we design your system

Your heat loss survey informs everything that follows:

Correct unit sizing

Flow temperature design matched to your existing emitters

A system genuinely specified for your property’s fabric and heat demand
