Aira Heat Pump: Stylish Scandinavian Heating

Aira heat pump

Aira has introduced the Aira Heat Pump, a product designed to shift European homes away from gas heating and towards electrification, leveraging advanced smart technology and sleek design.

The Aira Heat Pump is notable for several reasons, including its affordability facilitated by an all-inclusive monthly payment plan, cutting-edge technology and a pioneering 15-year ‘Comfort Guarantee’. The design, inspired by Scandinavian aesthetics, incorporates timeless elements, soft edges, intuitive lighting and a neutral colour palette, ensuring it remains stylish throughout its lifespan.

The product is controlled through a smart app and sleek thermostat, emphasising a digital-first strategy. It also introduces ‘Aira Intelligence’, a smart feature set that adapts to a user’s routine, planning heating and hot water schedules with precision. This system promises up to 40% savings on heating costs and a reduction of at least 75% in CO2 emissions from the outset.

Aira’s offering disrupts the market with its zero upfront cost, monthly payment model, and comprehensive ‘Comfort Guarantee’ covering performance, product and installation. This approach not only makes clean energy technology more accessible but also significantly lowers heating costs and CO2 emissions from day one. The design features ensure the pump blends into its surroundings, complemented by its quiet operation.

With roots in Sweden, a country where heat pump usage is widespread and contributes minimally to CO2 emissions, Aira’s product and engineering teams bring over two decades of experience to the development of this heat pump.

Based on the Aira Heat Pump Fact Sheet, here’s a list of its features and benefits:

I must admit that I was filled with confidence when I read the following line, and also saw that Aira appreciate the benefits of buffer tanks. ☹️ 

Outdoor unit

The outdoor unit draws in and compresses fresh air to heat your home and water. 🙄

@Derek M They wish to impress upon us that the fresh air is free (I’m not so sure about the ‘fresh’, especially after the latest UK government announcement that they wish to build some more gas-fired power stations, Arrrggh) and if HMRC get to know about air still being free – who’s to say how long before new legislation is introduced…?

Hi Toodles, have you been away?

I was more concerned about Aira’s obvious expert knowledge 🙄  of how heat pumps work, rather than whether air is free or not. So if it is only necessary to compress this ‘free’ air to heat your home, why do they bother using a refrigerant gas?

Perhaps Aira staff need to attend one of the MCS training courses?

Of course there will be the need for more gas fired power stations in the future, otherwise we will not have any electrical power when the wind is not blowing and the Sun is not shining.

What is rather annoying is that we as consumers will have to foot the bill for these new power stations, after government policy had forced many of the previous, still operational, gas fired power stations to shut down and be decommissioned.

Highly useful forward planning. 😜

No data sheets or produce literature yet, but a very glossy product launch. It’s a branded Vaillant product, so it should be good. I’m not a great fan of the beige box look of most outdoor monobloc ASHPs, but that Aira washboard front grille, it’ll take forever to keep clean! The beige box wipes clean in 30 seconds. 😉
I share Derek’s concern, the Aira product itself can’t offer any guarantees of efficiency, energy saving and life cycle cost reduction, but here’s another brand doing exactly that via their web site with a few clicks of a mouse. As a system it is only as efficient as it’s weakest part, which for retrofits (and far too many new builds) is the hydronic circuit it is connected to and the competency or otherwise of the installer.
In 10 years time ASHPs will have either revolutionised the European & UK domestic heating market, or become the latest mass mis-selling scandal. Time will tell.

Are you saying the ‘Aira’ heat pump is really a Vaillant, just with a different brand name and a different exterior casing? I know they started with installations using actual Vaillant models, but I did not know the Aira brand replacement is just a white label version. Aira has its own factory in Poland.

@Mars I have them coming to do a survey soon, so I’ll ask the surveyor. In a way, it would be reassuring if it is just a rebadged and reskinned Vaillant, rather than completely new. Though surely you don’t build a new factory just to fit the exterior cladding? Maybe they are assembling the whole thing, using Vaillant designs and, perhaps, components?

@Mars Will do.
I’m hoping they will be a good compromise between Octopus and Heat Geek. Heat Geek are really impressive and I’m convinced would give me a really good system, but they cost £10k more than Octopus. The decision isn’t just about money, but I can’t say money is no object. Although I’d probably save a bit more electric with HG, there’s no way I’d recoup £10k over the life of the heat pump. Octopus are staggeringly cheap, but they have overestimated my heat loss and are specifying a pump that is too powerful, so it cannot modulate enough to be efficient during autumn and spring.
It will be interesting to see if Aria are any better than Octopus. They are certainly slick with the marketing and the product aesthetics, but, as highlighted in this thread, they might be prioritising easy install and maintenance over optimal performance.

@IvanOpinion I suppose that as there are no free lunches in this world, the Aria price has to incorporate likely costs for the 15 years of annual servicing and maintenance contract and I think it is also a hire purchase or lease type of purchase without a great initial outlay isn’t it?

@Toodles I think in the UK you pay for it all in the first year, but spread over 12 months. So the risk is more that you have prepaid for 15 years of maintenance, but if they go bust then you never receive it.

@IvanOpinion I got a very definitive reply from Aira this morning: “The Aira Heat pump is not based on or produced by Vaillant."
Black and white. So it’s their own unit.

Which seems at odds with this article:
By switching to one of its heat pumps, which are currently built by German manufacturer Vaillant, Aira claims that households can save 25% on heating-related costs. The firm said production of its own-brand heat pumps would begin in Poland in 2024.
Mmm..

There’s a lot of “inspired by", “timeless elements", “facilitated by", “leveraging" and “disrupting the market" in this marketing blurb. If I was playing bull***t bingo I’d have called out already.
Whilst I’m aware they want to sell the product, my main issue is that there is a lot of implication it’s a product designed for use in Scandinavia (which would be a good thing considering how robust they need their kit to be) but nothing in there that actually claims it directly. 

“With its roots in Sweden…"
“The design, inspired by Scandinavian aesthetics…"
“Signature Scandinavian design…"
“Ensures a comfortable temperature even on the coldest days…" (how cold is coldest?)

It may well walk the walk too but all I’m seeing at the moment is smoke and mirrors riding in on the coat tails of real Scandinavian ASHP installations. The consumers making up the current UK heat pump market are confused enough already without having to wade through weasel words.

I had a good chuckle at this. 😉 The Aira YouTube product launch was targeting Germany, Italy and the UK markets, as a group launch of branded Vaillant product into those countries. Vaillant is made in Germany. There’s a lot of marketing BS around ‘Scandinavian countries are cold so we know how to make heat pumps work’. The HVAC Engineer in me shouts “it’s all about the absolute moisture content, stupid!" – Cold and dry Scandi weather is less arduous for a heat pump than the milder 100% humidity freezing fog perma-dank we get. The ice maker on my patio is testament to that.
I long to see an ASHP without a parasitic reverse cycle defrost method that robs heat of the hydronic circuit. Ebac has gone half way with a passive defrost feature, but is the only manufacturer I know to do so. I have a 30yr old Ebac CD30 industrial dehumidifier in my garage, still working, on R12 gas. It uses hot gas defrost, which is incredibly quick and efficient. They know a thing or two about this.

I spent 4 years working in Pakistan, not too far from Karachi, on the Arabian Sea coast, where the humidity was so high that after rain there would be remaining puddles of water for several weeks because the water could not evaporate even in blazing sunshine.

The requirement there of course was for cooling rather than heating.

I do believe that the Vancouver area of Canada has a similar climate to the UK.

To be frank, I hadn’t really thought about it like that but it makes perfect sense. That said, I think it perhaps even reinforces rather than detracts from the point I was making about the bandying about of language that implies suitability without actually claiming it. 
In Terry Pratchett’s book “The Light Fantastic", there is a wonderful quote covering this very topic.

“…descriptive writing is very rarely entirely accurate and during the reign of Olaf Quimby II as Patrician of Ankh some legislation was passed in a determined attempt to put a stop to this sort of thing and introduce some honesty into reporting. Thus, if a legend said of a notable hero that “all men spoke of his prowess” any bard who valued his life would add hastily “except for a couple of people in his home village who thought he was a liar, and quite a lot of other people who had never really heard of him.” Poetic simile was strictly limited to statements like “his mighty steed was as fleet as the wind on a fairly calm day, say about Force Three,” and any loose talk about a beloved having a face that launched a thousand ships would have to be backed by evidence that the object of desire did indeed look like a bottle of champagne."

Oh that we could hold Marketing departments to the same standards.

The company are extremely tight lipped about what is inside the case. Their PR is to manufacture an “Aira branded product", so where have a company that owns an energy storage company, a battery cell manufacturer and a steel producer acquired the experience in HP design and manufacture ( since 2015) or is it going to be a Grant/Chofu type OEM clone?  Enquiring minds would like to know, that’s all.

It’ll be a fairly standard R290 ASHP internally I think, covers, panels and grilles might be customised. They all come with serial Modbus comms now, from which 3rd parties can create user or installer control apps for remote control and monitoring, etc. That was what Aira were showcasing in their release video – it was all about the App & not the product. Such is the world these days, but the App is only as good as what it is controlling, the heat pump, which itself is only as good as the installation is. There’s a lot of variables at play – and for Aira to offer a 15 year guarantee means they either have an unprecedented control of the variables, or their guarantee is riddled with get-out clauses, especially the performance and efficiency guarantees. The 54year old cynic in me favours the latter.
I would be very surprised if Aira design & launch a completely new ASHP product from the ground up.

I found the details of the warranty. I don’t see any unreasonable get out clauses. And it is insurance backed. The only issue I can see is that it looks like they don’t guarantee the SCOP.
“The Warranty includes: 
the proper working of the air source heat pump; and  
the air source heat pump’s ability to maintain minimum indoor temperature as follows: 

Room 

Temp. (˚C) 

Living room 

21 

Dining room 

21 

Bedsitting room 

21 

Bedroom 

18 

Hall and landing 

18 

Kitchen 

18 

Bathroom 

22 

Toilet 

18 

 
The air source heat pump’s ability to maintain the above indoor temperature is conditional on the outside temperature not falling below the lowest expected temperature for the location where the air source heat pump is installed. You can find a list of the lowest expected temperatures in the Appendix to these Terms…
…If the air source heat pump fails to work properly within the Warranty Period, you shall contact us to inspect and arrange any necessary repairs. We may also contact you to inspect the air source heat pump system during the Warranty Period if we have reason to believe that there is an issue with it. We shall attempt to fix any identified issue at least three times. We may carry out any repairs or replacements that we deem necessary in order to fix the air source heat pump, which may include replacing the whole or part of the air source heat pump, adding or increasing the size of radiators, or changing pipework. You agree to allow us to carry out any and all inspections, repairs or replacements deemed necessary by us in order to get the air source heat pump working and complying with the Warranty. If you prevent us from doing this, it will invalidate the Warranty. 
We reserve the right to use qualified technical personnel of our own or companies operating in the same industry.  
If you do not report any defect to us as soon as reasonably possible and within two months from the date it was discovered, you shall not be able to ask us to fix the air source heat pump under the Warranty.  
You must not allow any third parties to carry out any repairs or other work involving tampering with the air source heat pump, and if you do, this shall invalidate the Warranty.  
If we are unable to fix the air source heat pump and get it working under the Warranty, we will refund the purchase price to you. 
If you sell your home which has the air source heat pump in it, the Warranty can be transferred to a new owner if you notify the change of ownership to us by e-mail to contact@airahome.com or by sending us a letter in the post. The new owner is then bound by the provisions of these Terms."

Their goal is to elevate the industry’s benchmarks,

How does that square with them using a 40 ltr buffer? I thought that buffers and LLH’s were the villains of the piece? Their marketing is undoubtably flashy and the word salad is second to none but why do I get an uncomfortable feeling that it is all fur coat and no knickers?

@Mars It is a physical and practical impossibility to balance a buffer in all instances and with varying loads, flow rates, temperatures and compressor outputs. It is quite simple really, if you have 1 side fixed, and the other variable, or the 2 side vary independently, there is no chance of maintaining a balance. To balance the buffer, the flow rates, temperatures and load have to be identical, on both sides, all the time without exception. Any variation, causes a reduction in efficiency. Basic Thermodynamics.

They do seem to hit what might be a sweet spot for a chunk of the market. I’ve had 5 quotes for a heat pump and they are cheaper than all except Octopus.
They have specified a buffer in their quote to me, so I’ve asked them to explain why it is better.

Caution everyone, this manual stipulates the installation of a buffer tank, so, the promised guaranty of supplying sufficient heat, may come at a very high price.
The unit is no quieter than any other unit out there (57 DB)
It says it has an “Operation limit temperature (TOL) -10ºC" then says “Operating limits -25°C to 45°C"  Take your pick.
The 10 Kw does not comply with permitted development, it is 0.72 m3, therefore needs planning permission for every installation.
It is not on the ENA database yet so connection may be an issue.
Just pointing the facts out, there is a lot of sales BS out there.
