Room at the inn for heat pump efficiency


11 November 2019
A 17th Century former drovers inn in Norfolk has updated its heating system with the latest air source heat pump technology thanks to renewable heating expert Finn Geotherm.
Located near Swaffham, the four bedroom period cottage was built in 1832. It was formerly a drovers inn and comprised two semi-detached cottages which were later knocked into one. When the current owners moved in, they inherited the cottage’s 35 year old oil boiler. The oil tank needed to be replaced and moved it away from the house to meet modern safety regulations.
After completing a full site survey, Finn Geotherm recommended a Panasonic Aquarea TCAP 9kW air source heat pump with a combined Dimplex cylinder which holds 150 litres of domestic hot water, plus a 75 litre buffer tank. The air source heat pump was installed in the same place in the garden as the old oil tank and the cylinder within the existing airing cupboard space. At the same time as the heat pump installation, nine new radiators were also installed.
The air source heat pump provides heating and hot water for the entire house. While the cottage has a low energy performance (EPC) rating, the heat pump is said to work efficiently to keep its owners warm. The thermal mass of the cottage with its thick walls and chimneys helps to retain the heat and the constant, steady state heating provided by the heat pump is also beneficial for maintaining the overall fabric of the building.
