Nestled in a quiet corner of rural West Sussex, Canfields is an award winning cattle farm with multiple dwellings requiring heating. The installation was part of a project designed to lower the carbon footprint and ongoing running costs of the site. The owners want to preserve Britain’s agricultural heritage and to help the next generation of farmers by ‘doing their bit’ for a sustainable future. Mindful that cattle farming is a considerable source of methane, anything that could be done to reduce the property's carbon footprint is a positive step. Since installation, to date the system has an impressive seasonal performance factor of 4.6 : 1. This means that the system is extremely efficient: for every 1 kW of electricity put into the heat pump, 4.6 kW are delivered for heating and hot water. In conjunction with the fuel saving benefiting the owners, there is a reduction of about 45% in carbon emission when compared to the previous oil-fired heating systems. This primary fuel saving compounded with the installation of the heat pump and pre-existing solar PV array, means that this farm has begun to operate in a more sustainable and economic way.

In 2015 isoenergy were contracted to design a ground source heat pump system to supply heat to the dwellings at Canfields Farm.

isoenergy installed a 64 kW heat pump system with a collector array of 4,000 metres of pipe in 150 metre long trenches. The heat pump system provides heating and hot water to a converted barn and two other dwellings.
