Quick Intro: Your Heat Pump Efficiency Comparison Cheat-Sheet
Thinking of swapping out that old boiler? You’re in good company. A proper heat pump efficiency comparison can feel like decoding hieroglyphics. But it needn’t be. Whether you’re eyeing an air source heat pump or considering the deeper dig of a geothermal system, we’ve boiled it down to plain English. In this guide, you’ll see performance side by side, peek at installation and running costs, and learn about UK grants that can shrink your bill—and your carbon footprint. Megawave: Eco-Friendly Heat Pump Efficiency Comparison Guide shows you how.
By the end of this article you’ll know:
– How air source and ground source heat pumps work.
– Real-world efficiency numbers.
– Upfront and operational costs.
– Available UK government incentives (hello, Boiler Upgrade Scheme).
How Heat Pumps Work: Moving Heat, Not Making It
Heat pumps don’t burn fuel. They shift heat around, using a refrigerant to capture warmth from the air or ground. Think of it like a reversible fridge: in winter it captures outdoor warmth into your home; in summer it flips to cool indoor air.
Both systems achieve remarkable efficiencies:
– Air source heat pumps can reach over 300% efficiency (3 kW heat for every 1 kW of electricity).
– Geothermal systems can hit 500–600%, thanks to steady underground temperatures.
This fundamental difference makes heat pump efficiency comparison essential before you choose.
Air Source Heat Pumps Explained
Air source units draw heat from outside air—even in freezing conditions. Modern “cold climate” models run smoothly down to –15 °C, thanks to advanced compressors and coils. Key perks:
- Lower installation cost (comparable to AC units).
- Dual heating and cooling function.
- Compact footprint beside your home.
At Megawave, we pair our air source heat pumps with zero-carbon R290 refrigerant. That cuts COâ‚‚ emissions even lower. Plus, you get expert installation, maintenance support and flexible finance options.
Geothermal Heat Pumps Explained
Ground source (geothermal) heat pumps bury loops in soil or deep wells. At 1.2 m below ground, temperatures stay in the mid-10s °C year-round. That stability supercharges efficiency—but adds to upfront cost. Pros:
- Steadier performance in harsh winters.
- Can slash energy use 25–50% compared to air source.
- Underground loop lasts ~50 years.
Downsides? You need adequate land or drilling rights. Installation can be disruptive—unless you work with a team like Megawave, who handle permits, digging and bespoke system design.
Comparing Efficiency: A Practical Heat Pump Efficiency Comparison
You’ve heard the headline numbers (300% vs 600%). But let’s break it down for a typical UK home:
- Average COP (Coefficient of Performance) for air source heat pumps: 3.0–3.5.
- Average COP for geothermal units: 4.2–5.0.
- Seasonal Performance Factor (SPF) in real world: geo systems often maintain a higher SPF through winter cold snaps.
In short, geothermal wins on pure efficiency—but air source is no slouch. If you’ve got modest space and want a quicker install, air source might be your cup of tea. If you’d like maximum savings over 20+ years, geothermal gives a larger return on investment.
Installation Costs: Upfront Investment
Here’s where wallets twitch:
Air Source
– Typical install: £5,000–£12,000.
– Similar to a high-end AC installation.
– Ideal for tight budgets or smaller gardens.
Geothermal
– Typical install: £12,000–£25,000.
– Involves digging trenches or vertical boreholes.
– Higher initial outlay, bigger long-term payoff.

Operating Costs and Long-Term Savings
A big slice of your savings comes after installation:
- Air source pumps can cut heating bills by 50–60%.
- Geothermal models often deliver 60–70% savings on energy.
Megawave systems use smart controls to optimise run-times. You’ll see fewer spikes on your meter. And with R290 refrigerant, you’re using a system that’s kinder to the planet—not just your pockets.

Space, Lifespan and Maintenance
Think long-term:
- Air source heat pumps last 15–20 years.
- Geothermal loops can serve you for 50 years; units last 20–25.
- Both need an annual service—changing filters, checking refrigerant levels.
Megawave’s maintenance support packages keep your heat pump humming. No surprises. No sudden breakdowns.
UK Grants and Incentives: Lowering the Tab
Unlike US tax credits, UK homeowners have access to:
- The Boiler Upgrade Scheme: up to £7,500 off an air source heat pump.
- Local authority grants (varies by region).
- Potential VAT reductions on renewable tech.
Palmetto’s US-based programme offers leasing and tax credits—but they don’t apply here. At Megawave, we guide you through every step: grant paperwork, eligibility checks, even liaising with your local council. That’s how we turn a big purchase into a smaller, manageable one.
Why Choose Megawave: Closing the Gap on Palmetto
Palmetto’s model—leasing heat pumps on a flat monthly fee—works well stateside. But in the UK, we’ve got a different playing field. Megawave’s edge:
- Utilising R290 zero-carbon refrigerant for minimal environmental impact.
- Expert design, seamless installation and end-to-end maintenance.
- Flexible finance options plus government grants to lower upfront costs.
- Local expertise, rapid response and a team that knows British building regs inside out.
We’re not just shifting heat. We’re reshaping how you experience comfort—efficiently and affordably.
