Geo-Exchange technology

Geo-exchange exploits the significant amounts of waste heat generated by various building operations, including cooling systems, ventilation systems, refrigeration equipment, wastewater, and even ambient air. These byproducts of energy consumption often go to waste, representing a missed opportunity for energy recovery. Geo-exchange networks harvest this resource to drive efficiency and sustainability.

While traditional systems often require a large number of evenly spaced boreholes, Geo Exchange employs a proprietary borehole design which enables us significantly reduce the number of boreholes and surface space required.

This innovative approach not only reduces costs and minimises disruption during construction but also preserves valuable real estate for future development. Making Geo-exchange a more attractive option for urban settings where space is often limited.

Our borehole casing design represents a significant technological breakthrough in ground source heat pump technology. Unlike traditional geothermal systems that utilise plastic U-tubes, Geo Exchange's borehole casings provide a robust and durable infrastructure that enables boreholes to be drilled deeper, up to 250 meters in almost any geology, tapping into the Earth's vast thermal reserves and maximising energy exchange..

Once captured from various sources, waste heat is meticulously stored within a network of boreholes drilled deep into the earth.
Combined with our management systems this allows us to treat the earth like a battery for thermal energy. Storing waste heat for hours, days or inter-seasonally for use as required & managing the extraction of heat from boreholes and provide a source of cooling in the summer.

The ability to store and utilise waste heat through the earth's thermal storage capacity is a key enabler of Geo Exchange's exceptional efficiency. This is combined with proprietary system monitoring and management tools which are used to both ensure availability and optimise system efficiency across heating and cooling seasons. Systems can be integrated with our customers preferred BMS tools and a range of aftercare & performance  management contracts.

On many larger estates decarbonising heating systems and optimising energy performance is a complex challenge which will depend on factors including building fabric, secondary systems and lifecycles of existing plant. This is often set against ambitious short and long term carbon reduction targets. Geo-exchange can be deployed to work alongside existing systems to displace some gas today and extended organically as funding and system replacements allow.
