Chorley St Laurence C of E Primary School install heat pumps under the playing fields

A Church of England primary school has substantially reduced carbon emissions by installing a heat pump below its playing field. 

To fit the ground source heat pump, The Parish of St Laurence C of E Primary School in Chorley, Lancashire, had to install 4,500 metres of piping under its playing field, and drill seven bore holes to a depth of 150m.  

Alongside the heating improvements, all lighting throughout the building has also been converted to more efficient LED bulbs, and solar panels have been added to the roof. Steps have also been taken to make the building more airtight, reducing draughts and heat loss.
