Ground Source Heat Pump Case Studies

Berkshire Domestic New Build Case Study – Berkshire

This substantial new property has lots of ground space; so horizontal ground loops were ideal. Because of a large hot water demand, a KBH 500 litre mains pressure storage tank was coupled with a Thermia Duo which also provides the space heating using underfloor.
