Introduction: Your Guide to Air Source vs Geothermal Installations
Switching to a heat pump can feel like stepping into jargon-land. Air source vs geothermal – which one’s right for your UK home? We’ll break down the big differences, plus costs, efficiency and environmental benefits. By the end, you’ll know whether to harness the air outside or the warmth beneath your feet.

Understanding Heat Pump Basics
What Is an Air Source Heat Pump?
An air source heat pump (ASHP) extracts warmth from outside air—even when it’s nippy. Think of it as a reverse fridge: it pulls low-grade heat, boosts its temperature with a compressor, then feeds it into your radiators or underfloor heating.
Key points:
– Operates in temperatures down to around –15 °C.
– Requires an outdoor unit, like a box next to your wall.
– Dual function: heating in winter, cooling in summer.
What Is a Geothermal Heat Pump?
Also known as a ground source heat pump (GSHP), this system taps into stable underground temperatures. Pipes buried 150–300 ft deep circulate fluid that picks up earth’s consistent warmth. The process is similar to an ASHP but more stable year-round.
Highlights:
– Stable COP (coefficient of performance) of 4.0+ even in winter.
– Underground loop installation—more planning but quieter operation.
– Can last 25 years indoors, 50+ years underground.
Key Differences: Air Source vs Geothermal
When weighing air source vs geothermal, three big factors stand out:
- Efficiency
- Geothermal pumps average a COP of 4.5—superior to air source’s 3.0–3.5.
-
Air source heat pumps dip in efficiency on icy days.
-
Installation Complexity
- Air source: quick install, minimal groundwork.
-
Geothermal: boreholes or trenches needed; more invasive.
-
Space Requirements
- ASHP needs a small outdoor footprint.
-
GSHP calls for garden space or drilling permission.
-
Noise Levels
- ASHP emits a low hum.
-
GSHP is whisper-quiet after setup.
-
Lifespan & Maintenance
- ASHP indoor units: ~15–20 years.
- GSHP loops: up to 100 years underground.
Cost Comparison: Upfront Investment and ROI
Price tag matters. Let’s cut to the chase:
Air Source Heat Pump
– Initial cost: £8,000–£12,000
– Running costs: moderate, rises in colder spells
– Payback: 7–12 years (with grants)
Geothermal Heat Pump
– Initial cost: £15,000–£25,000
– Running costs: very low, stable year-round
– Payback: 5–10 years (higher grant support)
Pro tip: Factor in the Renewable Heat Incentive (RHI) and local grants. You could slash your payback period by a few years.
Efficiency and Performance in the UK Climate
In Britain, soggy winters and mild summers define comfort needs.
- Air source systems shine when the mercury sits above 0 °C.
- Geothermal systems stay steady regardless of snow or rain.
However, modern ASHP models can handle chillier spells better than you’d expect. And if your home is well-insulated, an air source pump can be a wallet-friendly winner.
Installation Process: What to Expect
Air Source Installation
- Site survey and heat loss calculation.
- Outdoor unit placed on pads or brackets.
- Connect to indoor hydro unit.
Timeframe: 2–4 days.
Geothermal Installation
- Ground survey (soil type, water table).
- Borehole drilling or trenches excavated.
- Loop piping laid, then fitted to indoor unit.
Timeframe: 1–2 weeks (depending on groundworks).
The more invasive install is worth it if long-term savings and silence are top priorities.
Environmental Impact and Sustainability
Both systems score big on green cred:
- No fossil fuels.
- Lower CO₂ emissions vs gas boilers by 60–70%.
- Integration with solar PV or wind makes them near-zero carbon.
With Megawave’s use of zero-carbon refrigerant R290, you slash greenhouse gases further. That’s sustainability with a capital “S”.
Incentives, Grants, and Financing Options
Good news: the UK government is keen to back your heat pump switch. You can tap into:
- Domestic RHI payments.
- Boiler Upgrade Scheme grants up to £5,000.
- Local authority incentives.
- Flexible finance options from Megawave, spreading costs over months.
This package makes comparing air source vs geothermal less about sticker shock and more about lifestyle fit.

Maintenance and Lifespan
Keeping your heat pump happy is simple:
– Biannual service (spring and autumn).
– Filter checks and refrigerant top-ups.
– System diagnostics using smart controls.
Megawave’s expert installation and maintenance services ensure you get peak performance year after year. Expect 15–20 years from an ASHP and 25+ years for GSHP indoor units.
Choosing the Right System for Your Home
Ask yourself:
– How much garden space do I have?
– What’s my budget vs long-term saving goal?
– How noisy can my neighbours tolerate?
– Am I chasing the quickest payback or the longest lifespan?
A semi-detached home with limited garden? Air source is your friend. A detached house with acres? Geothermal could be the ultimate silent partner.
