It also keeps the base clear for the defrost water. 2. 2 Three days on site The old boiler came out and the heat pump went in, filled, tested and commissioned within three days. ## Every photograph from the job 3 photographs, no faces, nothing staged. ![The twin-fan unit raised on a brick plinth.](https://climateshieldlondon.co.uk/assets/img/case/wimbledon-sw19-01-960.webp) The twin-fan unit raised on a brick plinth. ![The same unit from across the garden.](https://climateshieldlondon.co.uk/assets/img/case/wimbledon-sw19-02-960.webp) The same unit from across the garden. ![The cylinder and controls in the loft.](https://climateshieldlondon.co.uk/assets/img/case/wimbledon-sw19-03-960.webp) The cylinder and controls in the loft. ## Thinking about a heat pump?

Larger units have two fans to move enough air over a bigger coil. They are used where the house needs more heat than a single-fan unit gives. ### Do you cover south-west London? Yes, including Wimbledon, Richmond and Kingston. ## More of our finished work Other jobs we have photographed. Tap one for the project.
