Vaillant Heat Pump Installation, Kingsbury NW9
In November 2026 our engineers fitted a Vaillant air source heat pump at a house in Kingsbury, NW9. The house heats through underfloor heating, and the hot water cylinder went into a small brick plant room off the back patio.

A two-fan unit, brought in by hand
The heat pump arrived crated on a pallet and came down on the lorry's tail-lift, where our engineers took the timber frame off. It was then wheeled through to the back of the house on a heavy-duty trolley.
It now stands on anti-vibration feet on the paving, in the corner between the house wall and the garden fence, beside a raised brick planter. The two-fan Vaillant monobloc sits out of the way of the patio and the back doors.
A plant room for the hot water
The plant room has its own door from the patio and a glazed roof. The hot water comes from a Joule Cyclone 500 litre unvented cylinder with two heat exchanger coils, and a Zilmet 100 litre buffer tank serves the heating side. When these photos were taken the pipes were already up through the plant room floor, ready to be connected.
The underfloor heating runs from a manifold under the stairs, with each loop marked with the room it serves.
Vaillant controls
The system runs on Vaillant controls: a sensoCOMFORT VRC 720f/3 controller, a VWZ AI heat pump appliance interface and a myVAILLANT connect gateway for the app.
