What the client wanted
The client, Bridge House was looking for an alternative heating option to oil, and due to the limited electricity supply available, opted for a Bi Vallent system.
What we installed
We installed 2 x 10kw Stiebel Eltron WPF ground source heat pumps, working in conjunction with an oil boiler, to provide this large property’s heating and domestic hot water requirements. .
The system was connected to the existing heating system, but radiators were upgraded to give the required heat output at the lower operating temperatures of heat pumps.
The heat pump manager decides when to bring each heat pump unit (depending on outside temperature), favouring the ground source heat pump units first, and using the oil boiler as a last resort in very cold conditions.
Domestic hot water heating was also provided by the heat pump and supplied to the house via a secondary hot water loop, ensuring unwanted cold water draw-off was kept to a minimum.
