The Aira Air Source Heat Pump

The Aira Air Source Heat Pump is designed for high efficiency and modern UK homes, using advanced technology to extract warmth from the outside air, even in temperatures as low as -25°C. It comes in three sizes (6kW, 8kW and 12kW), operates quietly at 46 to 51 decibels and holds an impressive A+++ energy rating (that's the highest energy class rating in the industry).

You’ll be able to access smart control through the Aira Home Energy app and thermostat, which lets you adjust heating, monitor savings and set modes for daily life easily. With natural R290 refrigerant, a sleek Scandi-inspired design and automatic learning features, the Aira Heat Pump is one of the best air source heat pumps on the UK market.

How the System Works

With the Aira Air Source Heat Pump, your heating system works by pulling free heat from the outside air and turning it into warmth for your home and hot water using just a small amount of electricity. It’s made up of an outdoor unit, an indoor unit, a buffer tank to store hot water and a modern thermostat, all connected to an easy-to-use app. Together, these components keep your home comfortable and energy-efficient while learning your schedule and adjusting automatically for more savings over time.

The outdoor unit gathers heat from the air and sends it indoors. Inside, your buffer tank makes sure there’s always enough hot water for radiators, underfloor heating, showers and taps.

The Aira app shows exactly how much hot water you have left in minutes, while you control your preferred settings and get heat pump maintenance reminders.

For ease, here are numbered steps on how an Aira air source heat pump works:

1. The outdoor unit pulls in free heat from the outside air, even when it's cold.

2. A special liquid refrigerant absorbs that heat and evaporates into a gas.

3. The compressor raises the temperature and pressure of the gas to make it hotter.

4. The hot gas passes through a condenser coil inside your home, transferring heat to your central heating system and hot water supply.

5. The refrigerant cools down as it moves through an expansion valve, turning back into a liquid so it can repeat the cycle.

6. Your indoor buffer tank stores hot water for radiators, underfloor heating and taps, ensuring steady warmth and supply.

7. The smart thermostat and app let you control temperatures, monitor energy use and activate special modes like extra hot water when you need it.

What Have Customers Said?

"EXCELLENT: from start to finish. Professional throughout: the initial assessment was straightforward, as was the more detailed second one; the installation - whilst somewhat disruptive - was carried out swiftly and efficiently by the Aira Team, ably lead by Andy Manning and comprising Reece Taylor, Robert Speed, Louise Stout, Mark Gumm and Jack Date. GREAT WORK: thank you. As for the final outcome: DELIGHTED, absolutely delighted. Warm house and plently of hot water. I would thoroughly advocate an air-source heat pump, and have no hesitation whatsoever in recommending an Aira installation." - Trustpilot

"Outstanding communication from beginning to end, from Sales, Planning, Installation and Aftercare. Adaptable installation over the week and despite unforeseen plumbing anomalies which complicated the install, these were overcome with planning and inclusion of us to possible solutions. James Chudleigh in sales demonstrated unparalleled communication from beginning, through sales and after, more than would expect from a salesperson. Since installation the water heat and power is vastly improved and better than we dreamed of. The app is intuitive and user friendly, looks great and has no overly complex bangs and whistles. Plumbers Paul, Ian and Billy could not have worked harder to get the job done and involved much extraction work of the old system. Very pleased aftermath researching we went with Aira rather than other local or national quotes and site visits." - Trustpilot

"I had a few hiccups with the system about 6 months after installation. Just needed a change of filter. The customer after care was brilliant. Zeke from Aira was punctual, polite and efficient. The problem was rectified quickly and I felt fully supported." - Trustpilot

"Heatpump installation by Aira last week and pleased with both the experience and result. The Aira team (Paul, Iain, Liam & Andrew) were knowledgeable, friendly and thoroughly professional and completed the job with minimal disruption and ahead of schedule. System appears to be working well and my neighbours have all taken a keen interest. Happy to give Aira a five star review and recommend them to others." - Trustpilot

Is the Aira Heat Pump Right For My Home?

When determining if an Aira air source heat pump is right for your home, it’s important to think about your specific heating needs and property type. Aira heat pumps are an excellent choice if you want an energy-efficient, low-carbon way to heat your home and hot water.

However, they work best in well-insulated homes. If your home currently has traditional radiators, you may need larger or new radiators to get the most from the heat pump, ensuring your home stays comfortably warm at lower temperatures compared to conventional boilers.

Aira Heat Pumps are also best for small to medium-sized properties due to their available heat pump sizes.

Ultimately, we always recommend that you have a professional assessment to check your home’s layout, insulation and heating system before deciding.
