No pressure. No pushy sales. Just honest advice from your local team.

How it works

Heat from the air, even in winter

An air source heat pump extracts heat from outside air and moves it into your home. It replaces your boiler — no combustion, no gas, no oil deliveries needed.

Air is drawn in from outside

Modern units operate efficiently down to –20°C — well below any UK winter temperature.

Heat is amplified via refrigerant cycle

A compressor multiplies the heat energy, the same way a fridge works — just in reverse.

Warmth is distributed around your home

Works with your existing radiators, underfloor heating, or a combination of both. Hot water too.

Why Go Air-to-Air?

Six reasons homeowners and businesses love them

1

Year-round comfort

Heating when it’s cold, cooling when it’s warm — one system does both, so you’re never at the mercy of the weather again.

2

Lower energy bills

Especially effective if you’re replacing electric, oil, or LPG heating. Air-to-air heat pumps are significantly cheaper to run.

3

Eco-friendly

Slashes your carbon footprint by using renewable energy drawn directly from the air. No combustion, no emissions on site.

4

No radiators needed

Ideal for open-plan living spaces, extensions, or light commercial premises where traditional radiators are impractical or unsightly.

5

Fast installation

Minimal disruption to your home or business. Our engineers work efficiently so you get maximum comfort with minimum fuss.

The installation is very neat looking, and all achieved with a minimum of fuss or inconvenience. My biggest praise for the company would be their communications. If they said it was going to happen - it happened, and at the timescale provided.

My parents heat pump system gave up just as the weather turned cold. Big eye watering job, but needed replacing ASAP. Turnaround time couldn't have been quicker, the engineers who did the install were all sound and did a tidy professional job. I'm still blown away by the lagging.. (there wasn't any before) it is artwork😁👌 cheers Eco installer and service ltd.

An exceptional all round experience with Eco Installer starting with my initial service enquiry efficiently handled by Annette. On the day of the service visit Chris went out of his way to educate me about heat pumps which as a life long oil boiler user was definitely needed and appreciated!

Frequently Asked Questions

Are heat pumps suitable for older properties?

Yes, when designed correctly. We carry out full heat loss calculations and assess your existing radiators, insulation and hot water system to ensure suitability. Many traditional properties can successfully run on heat pumps with the right system design.

Not always. During the survey and design stage, we assess whether your current emitters are correctly sized. Some properties require upgrades to maximise efficiency, but we only recommend changes where necessary.

The Boiler Upgrade Scheme currently provides funding towards eligible heat pump installations. We’ll guide you through available grants and confirm whether your property qualifies.

Most residential heat pump installations take a few days, depending on the complexity of the system and whether additional upgrades are required.

When properly designed and installed, a heat pump can significantly reduce running costs compared to oil, LPG or direct electric heating. Performance depends on property type, insulation and system design.

Yes. We provide ongoing servicing and maintenance to ensure your system continues operating efficiently and reliably for years to come.

Heat pumps are our core focus, but we also design and install solar PV and battery systems, along with heating system upgrades that support renewable performance.
