Types Of Heat Pumps & General Information

Air Source Heat PumpsAir Source Heat Pumps

With an air source heat pump, there is no need to dig or drill. Energy is extracted direct from the surrounding air in an economical and extremely environmentally friendly manner, without having to excavate your garden. Air source heat pumps are affordable, flexible and can be easily used to upgrade your existing heating system.

Advantages of Air Source Heat Pumps

  • Lower investment cost
  • No impact on the ground
  • No large plot needed
  • Ideal for retrofitting

Horizontal Ground Loop Heat PumpsHorizontal Ground Loop Heat Pumps

The horizontal ground loop collects solar energy that is stored in the ground. The loop is buried about one metre below the surface and energy is extracted from the ground. The length of the loop depends on your house, the size of the heat pump and local ground conditions.

Advantages of Horizontal Ground Loop Heat Pumps

  • Lower installation cost compared to vertical ground loop
  • The coil in the ground maintains an even temperature throughout the year
  • Allows passive or active cooling
  • Can also be used to extract heat from lakes

Ground Source Heat PumpsGround Source Heat Pumps

The vertical ground loop collects solar energy stored deep below the surface. A hole is drilled into the bedrock and a pipe is installed to a depth of up to 200 metres. The precise depth depends on your house, the size of heat pump and the surrounding conditions.

Advantages of Ground Source Heat Pumps

  • Needs very little space for installation
  • Minimal impact on the plot: can be placed in most gardens, however small
  • The hole in the rock maintains an even temperature throughout the year
  • Allows passive or active cooling and fits any building

Groundwater Heat PumpsGroundwater Heat Pumps

As the name suggests, a groundwater heat pump collects energy from the groundwater. The water is pumped up from a water borehole to a heat exchanger, where the energy is recovered. The water is then discharged back through another well. This solution can be the best choice when groundwater is readily available.

Advantages of Lake Groundwater Heat Pumps

  • Groundwater maintains a relatively high, even temperature, all year round
  • Minimal impact on the plot
  • Allows passive or active cooling
