RECC Why Ground Source Beats Air Source on Efficiency
Where air source heat pumps extract heat from outdoor air — which drops to near freezing on cold UK nights — ground source systems tap into the earth at 1–2 metres depth, where temperature remains a stable 10–13°C year-round. This thermal stability is the primary reason GSHPs consistently outperform ASHPs on efficiency metrics.
The UK's Energy Saving Trust reports real-world Seasonal Performance Factors of 3.0–4.5 for ground source systems, compared to 2.5–3.2 for air source. At a 3.5 SPF and 27.69p/kWh electricity rate, your effective heat cost is approximately 7.9p/kWh — substantially cheaper than oil (8–11p/kWh net delivered), LPG (12–15p/kWh), and electric resistance heating (27.69p/kWh).
Ground source heat pumps are particularly suited to rural, detached, and off-grid properties with adequate land, where the combination of poor existing heating efficiency and the availability of ground loop space creates optimal conditions for a fast financial payback.
Horizontal Loop vs. Vertical Borehole
| System Type | Land Required | Typical Cost | Best For |
|---|---|---|---|
| Horizontal Loop | 200–600m² garden/field | £12,000–£18,000 | Rural/detached with large garden |
| Vertical Borehole | 10–30m² surface area | £16,000–£25,000 | Smaller plots, urban fringe |
| Slinky Coil | 80–200m² trench area | £11,000–£16,000 | Medium gardens, good soil |

Ground Source Homeowner Results
Every saving figure below is from the homeowner's own bills — not a marketing estimate.
"We were paying over £200 a month on electricity. After our 4kWp solar system went in last April, our last three bills have averaged £43. The whole process — from filling in the form to panels on the roof — took three weeks. No hard sell, just a local installer who knew what he was talking about."
"We were spending £3,200 a year on heating oil. The heat pump cost us £4,100 after the BUS grant. First winter running costs came to £820. I wish we'd done it five years ago. The matched installer knew exactly how to deal with our 1970s farmhouse layout."
"We added a GivEnergy battery to our existing solar at the same time. The whole system now covers about 85% of our electricity use. The installer who came knew Brighton roofs — he'd done dozens on our street. The form took four minutes and I had three quotes within a day."
