What are Heat Pumps?

Ground source heat pumps

Quite simply, a ground source heat pump system (GSHP) takes energy from the ground to use for your heating and hot water.

The energy is generated by the sun and the heat can be extracted from pipes in the ground, from an underground aquifer or from a lake. The pumps work day in, day out, whatever the weather.

Air sourced heat pumps

These work in a a similar way to a Ground Source Heat Pump. However, rather than taking energy from the ground it takes it from the surrounding air to generate heat.

Systems are cheaper to install compared to the equivalent GSHP system as you do not need to install the ground array. However, performances (CoP = Coefficient of Performance) are not quite as good as a GSHP system.

Energy efficient?

Ground source heat pumps are efficient in their use and capture of energy. For every unit of electricity used it will transfer three to four units of heat. That makes it 300-400% efficient in its use of power to produce energy.

  • environmentally friendly
  • discreet and unobtrusive
  • lower carbon dioxide emissions than a gas heating system
  • cuts your bills
  • Renewable Heat Incentive (RHI) payments [link to page] covers installation costs

How does it work?

You do not need a lot of land for a GSHP system. Typically, the most efficient system is an ‘open loop’ borehole system that extracts water from an aquifer. This method can also give a separate water supply for the property.

The system we recommend, and the design and direction of the ground array, depends on the size of your property and the geological make-up of the land. This will be assessed during our survey stage.
