Ground Source Heat Pumps

Ground Source Heat PumpsGround source heat pumps use pipes buried in the garden to extract heat from the ground. This is usually used to warm water for radiators or underfloor heating systems. It can also be used to pre-heat water before it goes into a more conventional boiler. Beneath the surface, the ground stays at a constant temperature, so a ground source heat pump can be used throughout the year – even in the middle of winter. You can even get a grant.

A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe (called a ground loop) which is buried in the garden. When the liquid travels around the loop it absorbs heat from the ground. It can then be used to heat radiators, underfloor heating systems and even hot water. The length of the ground loop depends on the size of your home and the amount of heat you need – longer loops can draw more heat from the ground.

Normally the loop is laid flat, or coiled in trenches about two metres deep, but if there is not enough space in your garden you can install a vertical loop to a depth of up to 100 metres.

The benefits of ground source heat pumps

  • Reduce your fuel bills
    Ground source heat pumps run on electricity, so there’s no need to pay for gas, oil or solid fuels to heat your home.
  • Cut down on wasted electricity
    Heating your home with a ground source heat pump is much more efficient than using electric radiators.
  • Saving space
    A ground source heat pump system is compact, and requires no storage space for fuel.

Ground source heat pumps are an alternative to fossil fuels and can help reduce your homes CO2emissions. Ground source heat pumps add great value to your home and also help to cut your annual bills.

Ground source heat pumps should only really be considered after the ‘more fundamental’ energy saving measures have taken place (loft insulation, cavity wall insulation, double glazing, an efficient boiler). As an example, loft insulation with some grant aid will payback within a year. Ground source heat pumps are more expensive and have longer payback times. However the running costs are very low. Pickups will give you expert advice on choosing an air source heat pump system that suits your current and long term energy needs.

Worcester Groundstore Heat Pumps

Worcester Greenstore ground source heat pumps are suitable for a variety of properties and are designed to be the sole source of heating and hot water in the home. System heat pumps require a separate cylinder and can also be used with solar water heating. Combi heat pumps have an integrated cylinder.

For every single kilowatt of electricity used to power the ground source heat pumps, this system could generate four kilowatts or more in energy for your home.

Planning permission: Greenstore ground source heat pumps are certified by the Microgeneration Certification Scheme and planning permission for them has been eased significantly.
