What is an ASHP and how do they work?

Why choose an air‑source heat pump?

• Shrink your carbon footprint – Cut home‑heating CO₂ by up to 70 % versus an old gas boiler.

• Tame your energy bills – Tap into cheaper off‑peak tariffs and pair the pump with rooftop solar for even bigger savings.

• Future‑proof comfort – Heat pumps are the norm in chilly Norway and Sweden; the UK is catching up fast.

• £7,500 Boiler Upgrade Scheme grant – Available in England & Wales until March 2026 (first‑come, first‑served).

• Quiet & compact – Modern units hum along at 40–45 dB and need less space than you might think.

Running costs & real‑world savings

Electricity is pricier per kWh than gas, but an ASHP’s high efficiency shifts the maths in your favour. Example:

*Assumes 85 % efficient boiler at 7.9 p/kWh gas. **Assumes SCOP 3.2 at 28 p/kWh electricity. Accurate April 2025.

Switch to an Agile or Cosy tariff and schedule the heat pump to run harder when rates dip, and those figures look even better. Add solar PV and you can harvest truly low‑cost self‑generated kWh in spring and summer.

Monobloc vs split systems

We’ll design whichever layout suits your property, budget and aesthetics.

Grants & finance at a glance (2025‑26)

• Boiler Upgrade Scheme (BUS) – £7,500 off the upfront price if you own your home in England or Wales and have a valid EPC with no outstanding loft or cavity‑wall recommendations.

• Home Energy Scotland Grant & Loan – Up to £15,000 combined support north of the border.

• 0 % VAT on heat‑pump hardware and installation until March 2027.

• Green mortgages & EPC‑linked loans – Many lenders now offer reduced rates for low‑carbon retrofits.

Our team handles the paperwork so you don’t have to wrestle with forms.

From survey to cosy comfort – your installation journey

1. Free phone consultation – We chat through your goals, property and budget.

2. On‑site heat‑loss survey – Precise room‑by‑room measurements to size the pump and emitters.

3. Design & proposal – You receive a fixed‑price quote, BUS grant guidance and predicted running costs.

4. Installation (typically 2–4 days) – Our Heat Geek Elite engineers fit the outdoor unit, indoor controls and cylinder swap (if needed). We keep hot water disruption to a minimum.

5. Commissioning & hand‑over – We test, balance and optimise flow temperatures, then show you how to drive the smart controls like a pro.

6. After‑care – Optional service plan, remote monitoring and out‑of‑hours support for total peace of mind.

Maintenance & lifespan

An ASHP has fewer moving parts than a boiler and no combustion gases to vent. All it really needs is:

• Annual visual check and refrigerant pressure test.

• Quick clean of the coil and condensate drain.

• Filter rinse and software‑update check.

With gentle care you can expect 15–20 years of service before major overhaul, roughly double the life of a typical combi boiler.

Smart control & solar synergy

Pair your heat pump with a weather‑compensating controller or a smart tariff integrator (think Octopus Cosy or Intelligent) and you can pre‑heat the home when prices are low, then coast when the grid is pricey. If you’ve got solar PV, a diverter can prioritise surplus sunshine to your cylinder—free hot water, minimal grid draw.

Quick‑fire FAQs

Will I need bigger radiators? Often, yes—but not always. We’ll model each room and recommend slimline ‘low‑temp’ rads only where necessary.

How loud is it? About the same as a modern fridge—40‑45 dB at 1 m. Your bedroom is unlikely to hear it.

Does it work with under‑floor heating? Perfectly—that’s the most efficient emitter for a heat pump.

Can I keep my gas boiler as back‑up? You can. A hybrid system lets the heat pump do the heavy lifting while the boiler tops up on the coldest snaps.

What happens in a power cut? The pump pauses, just like a boiler with no electricity. We can advise on battery storage if resilience is key.
