We installed a Worcester Bosch CS7400iAW 7kW monobloc heat pump in Kingston upon Thames KT1, with a Green Storage 210-litre heat pump cylinder. The unit stands on a raised frame on a flat roof, and we managed the Boiler Upgrade Scheme grant for the owner.

The size came from a room-by-room heat loss assessment, and MCS certification was issued on completion.

How the job was done

Step by step, in the photographs taken on site.

  1. The Worcester Bosch unit on its raised frame on the flat roof, with the isolator beside it.

    A raised frame on the roof

    On a flat roof the unit sits on a raised frame, so the roof covering carries no point load and rainwater still runs freely underneath it.

  2. The same unit from the front.

    Sized room by room

    Each room's heat loss was calculated before the 7kW unit was chosen, which is what makes the difference between a system that copes in January and one that does not.
