moving closer : compact collectors

Finally with the help of a local registered Worcester-Bosch installer we might start digging up our garden mid June. The solution would be neither a bore hole, nor an air source heat pump but digging trenches to bury compact collectors and then using a combi ground source heat pump (a Greenstore 11 Combi) to provide heat and hot water for 9 rooms and 4 bathrooms. Technical specification is here.

We are also considering a secondary loop for hot water to reduce the time we wait for water to turn hot once you turn the hot tap on (which leads to wasting water).

The DTI sets out strict requirements to receive a grant (see this link).
