Air Source Heat Pump vs Ground Source Heat Pump : Which one is right for you?

If you are looking for an efficient and reliable way to reduce your heating bill, then a heat pump could definitely be the answer. But should you choose an Air Source or Ground Source Heat Pump?

What are heat pumps?

A Heat Pump is a great alternative to using other sources to heat your home. There are many varieties you can choose from depending on your requirements. Heat Pumps are very efficient at warming and cooling your home as they work by transferring thermal energy from one area to another. They are like refrigerators, but instead of heat being pumped out into the air around the refrigerator, the Heat Pumps heat into the conditioned environment.

Ground Source Heat Pump

Ground Sourced Heat Pumps (GSHPs) use pipes which are buried outside your property to extract heat from the ground, generated by both sunlight and rainfall. The ground stays at a fairly constant temperature under the surface, so the heat pump can be used all year round.

Ground Source Heat Pumps are considered the most efficient heat pumps, as they rely on the Earth itself to source heat.

Air Source Heat Pumps

Air Sourced Heat Pumps (ASHPs) absorb heat from the outside air which can then be used to heat your property and hot water system. The Heat Pump can be placed on a wall or on the ground outside your property.

What should you consider when selecting a heat pump?

Both Air Source and Ground Source Heat Pumps are extremely efficient and reliable, requiring little maintenance. Installing a heat pump will allow you to significantly reduce your carbon dioxide emissions and also claim financial incentives through the Domestic Renewable Heat Incentive scheme.

It may seem like a difficult decision but as MCS accredited suppliers and installers of both Ground Source and Air Source Heat Pumps we can work with you to decide which is the best solution for your property and budget.

What might we discuss with you?

We will talk you through the costs, impact of installation, efficiency, maintenance and operation of each system. You might also want to consider:

• Do you have sufficient outdoor space for the installation of pipes?
Whilst Ground Array pipes are usually installed horizontally in trenches, the process can also be performed vertically using deep bore holes – if space is at a premium. However if. you do not have outdoor space available that you want to be dug up, then we might recommend an Air Source pump.

• Is your home well insulated?
Heat Pumps work best when your home is well insulated, so consider insulating your home if you would like a Heat Pump, as this may make your system more efficient. However, a well designed and installed system can act as a highly efficient heat source for nearly all commercial and domestic properties.

• Do you have a space on a wall or ground?
An Air Source Heat Pump can be placed on a wall or on the ground if there is a suitable amount of space around it to allow a good flow of air. If your chosen space gets hit by the sun, this is an added bonus.

If a Heat Pump is not suitable for your property we can also advise across the range of renewable heating systems and technologies available, including Biomass and Solar Thermal to find the most suitable system for your home.
