Geothermal Heat Pumps

Geothermal heat pumps explained

A ground source heat pump (also known as geothermal heat pumps) uses the constant temperature of the earth (instead of air temperature) as the exchange medium to heat & cool your home or business. Most geothermal heat pumps can heat your domestic hot water tank too. 

Ground source / Geothermal heat pumps are a clean, eco-friendly source of energy. They circulate liquid (a mixture of water and antifreeze) through pipes that are buried deep in the ground. The liquid absorbs the naturally occurring heat stored in the ground, and it is then compressed and raised to a higher temperature. A heat exchanger extracts the heat and sends it to a heat pump which then transfers it to your home heating system.

In winter, the heat pump transfers the heat from the ground to warm up your home


In summer, the heat pump transfers the heat from your home into the ground

Long-term savings

While ground source heat pumps require a more substantial upfront investment, they also deliver more long-term savings. Geothermal heat pumps have a much higher energy efficiency than air pumps, and once installed, they require very little maintenance. Our technicians will design a system to suit the climate you live in, the layout of your property, and the heating requirements of your home. Call us today for a free quote!

Geothermal & solar work in tandem

Integrating solar with your geothermal heat pump system allows you to take advantage of both renewable energy sources. Ground source systems require a modest amount of electricity to run, and if you use your solar panels to generate this electricity, you will reach new heights of efficiency, whether you are a homeowner or a business owner. Our expert team of technicians can help you review your options and start planning a change today.

Advantages of Geothermal heat pumps

Cheap to run

Did you know ground source heat pumps are much cheaper to run than conventional gas or electric heating systems? You'll notice the difference on your energy bills, especially as energy prices continue to increase.

Energy Efficient

Ground source heat pumps are more efficient than air source heat pumps over the long-term because the ground temperature is more constant than the air temperature and not affected by seasonal changes.


Our ground source heat pumps utilise the latest technology from respected brands, so maintenance requirements are almost non-existent. Most geothermal systems are designed to last for well over 25 years.

    "John & Declan have run a fantastic service. My wife & I purchased a new house with an already heated slab which has never been used, but the builder hammered a star picket through a pipe which deactivated the whole system. John came out almost immediately & took one look at the system & immediately knew the problem. I don’t think you could find any company who could offer such immediate service & expertise. Congratulations John!"

    "John took on a complex job in installing our geothermal system in a very tricky house. His task was complicated by having to survey a previous installation of hydronics that was left unconnected & buried in the building. He did an excellent job & we now have a state of the art heating & hot water system that is so efficient & economical. John’s attention & commitment is second to none."
