Ground-source heating and cooling
A renewable source that starts with the site beneath the building.
Ground-source technology uses energy stored below the earth's surface for heating, cooling and hot water.
Review feasibility before fixing the plant layout, ground works and connections to the building systems.
Ground-source energy
Ground-source heating, cooling and hot water support for suitable sites.
Ground-source systems can support heating, cooling and hot water by using stable temperatures below the surface as part of the energy exchange.
Cooling
Year-round conditioning
Ground-source systems can support cooling as well as heating where the design allows.
Hot water
Hybrid hot water contribution
A compatible hybrid system can recover excess cycle energy to help heat water.
Efficiency
Lower operating cost potential
Stable ground conditions can support efficient heating and cooling when site feasibility is suitable.
Feasibility process
Designed around site conditions and building loads.
This approach needs early coordination between site feasibility, heating/cooling loads and hot water integration.
- 01
Review loads
Confirm heating, cooling and hot water demands for the building.
- 02
Check site conditions
Assess available area, access, ground works and feasibility constraints.
- 03
Plan integration
Coordinate the equipment with storage, controls and heat delivery systems.
- 04
Confirm delivery scope
Resolve installation sequence, commissioning and service access.
Technical planning
The ground loop, plant and loads must be designed together.
These systems depend on ground-source feasibility and close integration with the heating, cooling and hot water design.
- Ground source
- The system uses stable underground temperatures as the heat source or sink.
- Hybrid module
- Some systems can recover energy from the refrigeration cycle for hot water support.
- Load profile
- Heating, cooling and hot water demands determine equipment and storage strategy.
- Site works
- Ground access and installation feasibility must be checked early.
Suitable projects
Where ground-source systems may be considered.
- Homes needing heating and cooling
- Projects considering ground-source energy
- Buildings with suitable ground works access
- Hydronic systems seeking renewable input
- Projects with hot water integration goals
- Early-stage designs before plant decisions are locked
FAQ
Common geothermal heating & cooling questions.
What is ground-source heating?
It uses energy stored below the earth's surface as a heat source or sink for heating and cooling systems.
Can this system also provide cooling?
Yes. Ground-source systems can support heating, cooling and hot water capabilities when designed for the required loads.
Why does site feasibility matter?
Ground works, available area, geology, access and system loads all affect whether this approach is practical.
Can it connect to hot water?
Some hybrid systems can contribute to hot water heating, but storage and controls need to be designed around the project.
