Impressively efficient. Equally quiet.
Equipped with modern technology, the outdoor unit is engineered for efficient performance, low maintenance and quiet operation.
A+++ energy rated
The Aira Heat Pump is so efficient that it boasts the industry's highest possible energy class rating (A+++).*
Industry-leading SCOP rating of 4.7
There's a product rating called SCOP (Seasonal Coefficient of Performance) which looks at a heat pump's performance over a year. A rating over 3.5 is good. And the Aira Heat Pump? An impressive 4.7.
Whisper quiet (56-57 dB)
The outside unit is designed not to disrupt and makes a gentle running sound similar to that of the fridge in your kitchen (56-57 decibels).
Uses natural R290 refrigerant
The Aira Outdoor Unit uses the R290 refrigerant. It's natural, efficient, non-toxic and free of ozone-depleting properties.
Distinctive, beautifully designed and timeless, the Aira Outdoor Unit is styled to fit naturally into its surrounding environment.
While the exterior design is crafted for longevity, it also enhances performance. The angles of the ribs on the front are crafted to maximise the amount of air entering the unit, while the back is engineered to minimise icing issues during winter.

Where should the outdoor unit be placed?
During our free home energy assessment, our Aira Clean Energy Experts will recommend the best location for your outdoor unit. If you have a specific location in mind, we will do our best to make it possible.
Upon installation, your Aira Technician will provide further advice on location, maintenance and usage.
How much noise does the outdoor unit make?
When in operation, the Aira Outdoor Unit makes a gentle running sound measuring between 56 and 57 decibels. This is a similar noise level to your fridge.
What is the expected lifetime of the Aira Outdoor Unit
With the Aira Comfort Guarantee, we promise that the Aira Outdoor Unit will continue to provide a cosy indoor temperature for the next 15 years. Or we'll come out to fix it. And, if you want to extend your cover when your 15 years are up, that’s easy and affordable.
Can I install my own heat pump?
The installation of a heat pump must be carried out by a trained professional. Our Aira Technicians are MCS-certified and will install your Aira Heat Pump. They will also provide expert advice on heat pump location, maintenance and usage.
Can the Aira Heat Pump be used for heating & cooling?
Your Aira Heat Pump can work alongside an air conditioning system, but it can also be adapted to function as its own cooling unit. With some installation adjustments, like installing fan coils, the exact same technology that heats your home can also cool it down in summer. Contact Aira Customer Support to learn more.
How is the outdoor unit protected from bad weather?
Our air source heat pumps are sealed units designed to withstand all weather conditions. They have built-in safeguards, like an automated de-icing cycle, to protect against extreme weather.
Will I need to use my heat pump in summer?
Yes. You will still need to use your heat pump for hot water production during the warmer months, but it will use much less energy than in the winter because it will not be heating your home.
Indoor units
Water heated by your outdoor unit is stored and distributed by two components installed inside your home; the Aira Indoor Unit and Buffer Tank.
Aira Intelligence
Your Aira system is full of smart, connected features which heat your home and hot water with optimal efficiency. It's called Aira Intelligence.
15 Year Comfort Guarantee
The Aira Heat Pump is covered by our Comfort Guarantee, which means any parts and labour required to ensure the function of your product and installation are on us for the next 15 years.
