Greenstore 7 System

Greenstore ground source heat pump close up
Ground source heat pump

Description

The Greenstore 7 System ground source heat pump is designed to work with a cylinder to produce heating and hot water for your home.

Ground collectors buried within your land collect stored solar energy there and transfer it to the heat pump. The ground source heat pump then uses this energy to deliver heating and hot water to your system.

The kilowatt output you need from the ground source heat pump depends on the heat load of your property.

Efficiency

  • COP 3.9 The Greenstore 7 System has a coefficient of performance (COP) of 3.9. The CoP is a simple calculation which works out how much energy the heat pump is able to extract from the energy source compared to the amount of electrical energy used by the heat pump.
