Greenstore 7 Combi
Description
The Greenstore 7 Combi ground source heat pump can help to save space in your property because it contains an integrated cylinder.
Ground collectors buried within your land collect stored solar energy there and transfer it to the combi heat pump. The ground source heat pump then uses this energy to deliver heating and hot water to your home’s system.
The kilowatt output you need from the ground source heat pump depends on the heat load of your property.
