What are ground source heat pumps?
Ground source heat pumps collect energy stored in the earth and use it to heat water in a cylinder for the provision of central heating and domestic water in the home.
This is one of the most advanced technology available for home heating and hot water . because the earth itself ‘stores’ energy it is extremely reliable and constant energy source, it creates no harmful emissions and only a small amount of electricity is used to drive the heat pump itself.

How do they work?
A heat pump works in the same way as a refrigerator, but in reverse. The collection system consists of a single deep borehole in the garden or, where space permits, a looped array of pipes buried approximately 1.2 metres below the surface enabling the ground source heat pump to extract heat stored in the earth. This low temperature energy passes through a CFC-free refrigerant circuit which converts it into higher temperatures to heat the home. In summer, with an underfloor heating system connected to the heat pump, energy flow can be reversed, cooling the room to a comfortable temperature. If you’re considering having a ground source heat pump installed you may be eligible for a grant through the low carbon buildings programme.

How energy efficient are they?
Heat pumps provide heating and hot water with extraordinary efficiency. The only energy consumed is for the periodic operation of the pumo, up to 4.5Kw of heat can be provided to the house for heating and hot water. A heat pump can also reduce the CO2 emmissions from a domestic property by up to 40%. The heat pump unit also contains a 4kw immersion heater that if necessary automatically boosts the hot water temperature.

Is your home suitable for a heat pump?
the heating characteristics of heat pumps make them perfect for homes with underfloor heating. They are suitable for a variety of homes. The vertical borehole requires minimal space in the area around the building. The only limitation for heat pumps is in achieving a satisfactory balance between the energy loss of the building and the required flow temperature of the heating system. For these reasons heat pumps are most suitable for new buildings and major refurbishments.

Benefits:

• Eliminate fuel bills, they run on electricity so there is no need to pay for gas, oil or solid fuels.
• Reduces CO2 emissions.
• Cut down on wasted electricity as it is much more efficient then electric radiators.
