A PRIMARY school has moved a step closer to realising its sustainability goals after plans for new heat pump heating systems were approved.

Farsley Farfield Primary School, in Cote Lane, has seen its plans for the two new air source heat pumps given the green light by Leeds City Council.

The heat pumps, the school said, will help it achieve "improved long term energy viability and sustainability".

Heat pumps take available heat from the ground or air surrounding a building and increase it to a more useful temperature for use in the building.

This renewable source of heat can be used to create warm air or water (for space and central heating) as well as hot water (for both central heating and hot water supply).

It achieves this by taking the same principle that works in a fridge and utilising it in reverse.

It is a more environmentally friendly method of heating a building than conventional gas boilers, allowing the school to operate in a greener manner.

While expensive to install, they have lower running costs and need less maintenance and are also safer.
