Discreet operation
The collector sits underground and there is no outdoor fan unit beside the home.
Quiet heat with long-term thinking · Choose the collector route
Planning below the surface
Ground source heating provides steady, low-temperature comfort using heat from the ground. Land, access, geology and the wider heating system determine whether it suits the property.
Steady comfort
Low-temperature heating is designed to maintain a consistent indoor environment.
A long-term asset
The ground collector is planned around the property and wider project, not a short-term product swap.
Horizontal ground loops
Pipework is laid in trenches across a suitable area of land. Needs meaningful space, workable ground and machinery access.
Vertical boreholes
Deeper collectors reduce the surface land required but need specialist drilling. Feasibility, access, geology and cost must be established early.
Compare with air source
Where land or groundwork makes ground source impractical, air source may offer a simpler route. The best technology is the one the property can support well.
Start below ground
Balance land, geology, heat demand and long-term performance.
Warmaway considers the ground array and the indoor heating system together, with specialist groundwork or drilling coordinated as part of the project.
Where ground source makes sense
Ground source systems suit properties with sufficient land for horizontal loops or a viable borehole solution. Access, ground conditions and heat demand need early consideration.
Designing the full system
The collector, heat pump, hot-water storage, emitters and controls must work as a single system. Warmaway builds the proposal around the property and its long-term use.
A specialist project, clearly managed
Groundworks, drilling, plant space and commissioning require coordination. The page sets expectations early so customers understand the survey and design stages before committing.
Funding support
Upfront support for eligible low-carbon heating.
Available support depends on the technology, property and existing heating system. Warmaway checks eligibility and current scheme rules before you apply.
£7,500 — Standard BUS grant
Available for eligible air-to-water and ground-source heat-pump installations in England and Wales.
Up to £9,000 — Eligible off-gas homes
For qualifying oil- or LPG-heated properties without a mains-gas connection until 31 March 2027.
A property-led answer
Is the property suited to a ground-led project?
A viable heat source is only the beginning. The project also needs a sound heating design, suitable plant space and a realistic construction programme.
Often a good fit when...
- There is land for trenches or access for borehole drilling
- The property has a long-term low-carbon heating plan
- Plant and hot-water storage can be accommodated
- Groundworks can be coordinated with landscaping or construction
We still assess...
- Peak heat demand and annual energy requirement
- Land area, access and underground constraints
- Geology and borehole feasibility where relevant
- Plant-room, cylinder and internal distribution space
Ground array to warm rooms
Coordinate the site work and heating design as one project.
Available land and access usually determine the first big decision.
Feasibility check
We review property demand, land, access and project goals.
Technical survey
Collector approach and system requirements are assessed.
Detailed design
The full heating and hot-water proposal is prepared.
Coordinated delivery
Groundworks, installation and commissioning are managed in sequence.
Designed before it is sold
What the feasibility stage needs to establish
The ground collector cannot be separated from the heat pump and building. Each part has to be sized around the same design demand.
What we assess
- Room-by-room heat-loss calculation
- Ground-loop or borehole design basis
- Access for excavation or drilling
- Emitter temperatures and required upgrades
- Cylinder, buffer and plant-space layout
- Electrical supply, controls and MCS requirements
A complete project
What the project includes
- Early property and collector feasibility review
- Detailed heat-loss and heating-system design
- Coordination of collector and plant requirements
- Clear proposal for equipment and enabling works
- MCS installation, testing and commissioning
- Control handover and long-term servicing options
Specialist, but understandable
A complex project should still feel clear to the homeowner.
Questions, answered simply
Everything you need to know before booking.
Do I need a large garden?
Horizontal ground loops need meaningful land area. Boreholes can reduce surface-area requirements but involve specialist drilling and feasibility checks.
Can underfloor heating be used with ground source?
Yes. Low-temperature underfloor heating can be a strong match when properly designed for the building heat demand.
How much land do horizontal loops need?
It depends on the building demand, collector design and ground conditions. The available land must be assessed rather than judged from a fixed garden-size rule.
Are boreholes always better than trenches?
No. Boreholes use less surface area but add drilling complexity and cost. Horizontal loops can be practical where suitable land and access are available.
