Ground Source Heat Pump

Transferring heat from the ground to your home.

Ground source heat pumps will provide hot water and heating for properties, from homes to commercial properties, in one of the most efficient and cleanest ways to produce thermal energy.

The ideal design of a ground source heat pump (GSHP) is dependant on the area surrounding a property. The cheapest method for installing ground source heat pumps is by creating a horizontal loop, which requires a large surface area of land (approximately 2.5 times the square meterage of the house, on average). If there isn’t enough land available, the alternative would be to create a vertical closed-loop system. Both offer similar levels of efficiency and each design has its own individual advantages. A ground source heat pump will absorb a constant level of geothermal heat, stored in ground water, to produce the thermal energy used for heating and hot water.

Ground source heat pumps are run using electricity. For every 1kW of electricity used to operate a heat pump, 3kW to 5kW of heat energy is produced and available on demand for heating.

A ground source heat pump provides a clean way to heat homes and buildings, free of all carbon emissions and other pollutants. By making use of the solar energy stored in the ground, ground source heat pumps are able to provide one of the most energy-efficient ways of heating homes and commercial buildings. Solar re-charge of the ground is an important part of ground source energy which is utilised to increase the efficiency of ground source heat pumps.

 

Ground source heat pumps work for a wide variety of homes and commercial buildings and are particularly appropriate for projects where low environmental impact is important.

Heat pumps can be installed anywhere in the UK. They can be installed by digging out shallow trenches and laying coiled pipes in a horizontal fashion, or by creating a vertical borehole and creating a closed-loop system. It's also possible to lay what is known as a water source heat pump, which absorbs heat from a nearby water resource, such as a pond, a lake or even the sea. Heat-collecting pipes in a closed loop, containing water mixed with a small amount of antifreeze extract, absorb and store the heat from natural sources. After being compressed, this stored energy is then at a temperature where it's possible to be used to provide general area heating and domestic hot water.

Ground source heat pumps are incredibly versatile as they can also be reversed during the summer months to provide cooling.

The only energy used by a Ground Source Heat Pump is electricity to power the compressor and the circulation pumps which transfer heat energy from the ground into the building. A well designed ground source heat pump installation will deliver three or four times as much thermal energy (heat) as is used in electrical energy to drive the system. For a particularly environmental solution, green electricity can be purchased.

GSHP have been widely adopted across North America, Sweden, Germany and Switzerland for many years. Typically, they do cost more to install than conventional heating systems, however, that initial cost is recouped because the heat pumps have very low maintenance costs and can be expected to provide safe, reliable and emission-free heating for well over 20 years.

The heat pump system work best with heating systems which are optimised to run at a lower water delivery temperature than is commonly used in radiator systems. As such, they make an ideal partner for underfloor heating systems.

HOW DO GROUND SOURCE HEAT PUMPS WORK?

Ground source heat pumps work by absorbing natural heat from the ground and transferring the heat into homes or commercial buildings to provide heating for rooms and water in the buildings without burning any fossil fuels.
