What is Ground Source Heat Pump system

Ground source heat pumps provide an efficient and green way of heating and cooling buildings, making use of renewable energy stored in the ground.

ENER-G Ground Source Solutions Ltd is one of the UK’s leading installers of ground source heat pump systems. ENER-G delivers complete ground source heat pump (GSHP) solutions for the public and private sector.

ENER-G Ground Source Solutions Ltd aims to successfully deliver highly efficient renewable energy solutions to customers that exceed their expectations.

Ground Source Heat Pumps Technology

The technology is based on the stability of underground temperatures. The ground a few feet below surface has a very stable temperature throughout the year. Ground source heat pumps use a buried ground loop to transfer this heat from the ground into buildings to supply space heating and hot water, providing one of the most energy-efficient ways of heating buildings. Ground source heat pumps can be installed in most of the UK.

A heat pump system can be used for air conditioning too, by providing cooling. It does this by transferring excess heat from the building back into the ground.

There are three main elements in a typical ground source heat pump installation:

Ground loop
A closed circuit pipe is buried in the ground, filled with a mixture of water and antifreeze, which is pumped around the pipe absorbing heat from the ground.

Heat pump
The ground source heat pump is operated from electricity and extracts heat from the ground, and uses it for heating purposes. In summer the cycle is reversed and heat is transferred into the ground.

Heat distribution system
The heat distribution system is inside the building and consists of radiators or under floor heating for space heating and in some cases water storage for hot water supply.

Ground Source Heat Pumps System Benefits

• High energy efficiency – typically a coefficient of performance (COP) of between 3 and 5
• Enables clients to meet European and UK legislation applicable to renewable energy
• Significant reduction in heating costs
• Very low maintenance costs
