Samsung Heat Pump, Enfield EN3
An 8kW Samsung Gen 7 sized from a heat loss survey, a 300-litre cylinder for a family's hot water, and the house split into two zones so each part is heated on its own schedule.

A Samsung heat pump with two heating zones in Enfield
We fitted a Samsung Gen 7 8kW air source heat pump to a family home in Enfield EN3, with a Joule 300-litre unvented cylinder and a two-zone heating system. The size came from a room-by-room heat loss calculation, not from the size of the old boiler. The unit runs on R290, a refrigerant with a global warming potential of 3, and carries Samsung's 7-year warranty through our approved installer status. The cylinder's stainless inner vessel has a 25-year warranty.
The survey measured every room and worked out how much heat each one loses on a cold day. That total, not the rating of the gas boiler it replaced, is what set the heat pump at 8kW. The outdoor unit stands against the side wall on anti-vibration feet. It uses none of the garden anyone would actually sit in, and the pipe run to the cylinder inside stays short, which keeps the heat losses on the way down.
The house is split into two heating zones with their own controls, so the part of the house in use can be warm without heating the part that is not. The 50-litre buffer tank keeps the heat pump running smoothly when one zone closes and the other stays open.
