We replaced the gas boiler in a renovated and extended Epsom KT19 home with an 8kW Samsung Gen 7 heat pump and a 250-litre Samsung cylinder. Underfloor heating downstairs and radiators upstairs run as separate zones with a buffer tank and Hive wireless thermostats.

With new insulation and triple glazing throughout, the house needs far less heat than before, which is why 8kW is enough. The £7,500 grant was applied.

## How the job was done

Step by step, in the photographs taken on site.

1. 1 Two kinds of heating, two zones Underfloor heating and radiators want different water temperatures, so they run as separate zones with their own thermostats, and a buffer tank lets each draw what it needs.
2. ![The Samsung Gen 7 on anti-vibration feet on its concrete base beside the fence.](https://climateshieldlondon.co.uk/assets/img/case/epsom-kt19-01-960.webp)   2 Sited round the extension The outdoor unit was positioned to meet Samsung's clearance requirements around the layout of the new extension, set into a planted border on a hard base with a short pipe run.
3. 3 Working alongside the builders On a renovation, the heat pump is one trade among several. The heat loss survey, pipe routes and commissioning were planned around the builders' programme.

## Epsom KT19: questions about this job

### Can underfloor heating and radiators run from one heat pump?

Yes, as separate zones with their own controls. A buffer tank often sits between them so the heat pump runs smoothly whichever zone is calling.

### When in a renovation should the heat pump be planned?

Before the floors go down. The survey, the underfloor layout and the pipe routes are easiest to get right at the start.
