All of the 2.5kW and up units are discounted. Oddly enough, the 2.0kw unit is not, making it more expensive than the 2.0.

Units include installation, except that they require an electrical access point that must be pre-installed. I had this done a few years ago for ~£100 by a local electrician.

Details

The Sensira range by Daikin is a great all round performer, with seasonal efficiency values of A++ in cooling and A+ in heating. These highly efficient systems can both heat and cool a space with ease. Made to be very discreet with a compact, space-saving design, the Sensira is great for many different applications including bedrooms, garden cabins, home offices, garage conversions and many more.

All systems are installed by fully qualified F-Gas registered engineers. A 16 amp power supply must be installed at the location of the outdoor unit prior to installation to enable the engineer a point to wire into (please see the Installation Guide).

The Daikin Sensira range is equipped with many different functions to enhance the environment of any living or working space.

Super Compact Design
The Sensira 2.5kW has a width of just 77cm, allowing for more installation possibilities by reducing the space required in your home.

Whisper Silent
The Sensira indoor unit operating noise has been designed to be as quiet as possible. In fact, the ‘Silent’ button on the remote control lowers the operation sound of the indoor unit to 20dB(A) for a comfortable night's sleep.

Different Modes

Econo Mode - Decreases power use so that other appliances that require larger consumption can be used
Comfort Mode - Guarantees draught free operation by preventing the warm or cold air being directly blown on to the body
Powerful Mode - Can be selected for rapid heating or cooling

Features

Vertical Auto Swing - Automatic vertical moving of the air discharge flaps for efficient air and temperature distribution throughout the room

This is my sector; a couple of notes

This type of heat pump (yes it is a heat pump) are very efficient at cooling and heating; as long as you can change some mindset (forced air vs radiant) and ignore the many myths it is far better (and more efficient) than Air-To-Water heat pumps, but of course don't provide hot water.

2.5kw is a small system; it's really only suited for bedrooms (in a standard sized house) as it's there is less heat load during the night, and will be fine for heating in the summer. Any other room (bar possibly the bathroom) I would suggest 3.5kw.

I don't think this is a particularly good deal; it's NOT a bad deal, but a fair price. However, I suggest it's going to be better to seek a local installer, who will be best suited to look after you before, during and after install. Costco are subcontracting here, so you're paying a middleman (and granted will have some decent after sales)

A personal note; Daikin is historically is rated very good, and still considered to this day as "premium", and do provide decent warrantee periods to back this up. However, in recent year myself and others have seen an increase of issues with Daikin QC, cheap copper and PCBs, leading us to move away from them in favour of others; myself, I specify Panasonic, and can also recommend Mitsubishi Electric. I can't recommend Daikin any more, despite being my preferred brand in previous years. (edited)

If it's up to 2.5kW these can be wired to a normal 3-pin plug and plugged into a regular socket inside your house, no need for an electrician to do anything extra. At least that's how I have ours installed, the AC company installed the whole system then just left a normal wire with a 3 pin plug that goes into a regular socket. Unless of course you don't have a suitable socket nearby.
16th May
Air conditioning is a fixed appliance, so regulations state it needs to be a fixed supply; the supply on a 2.5kw AC system is relatively small, so can be a fused spur, but ideally wants its own dedicated supply
16th May
I'm thinking of installing a split unit but confused about the power supply. If there is no power outlet outside, can't the power cable be run through the drilled hole (provided it's got the necesseary protection sleeves)? (edited)
16th May
I had 3 units installed 3 years ago and the installers ran armored cable from the inside unit to the outside unit and then back inside each room to connect to a socket. No need for an outdoor socket. I attached power meters to each to track electricity usage and found it to be remarkably low despite the scare stories. I have the AC on my room on 24/7 6 months of the year and it averages to around £2 per week over those 6 months.

PS - My units were 2.5KW Mitsubishi ones and cost £800 each including installation so this may not be a great deal unless prices have gone up significantly since I had mine. (edited)
16th May
For those interested in this, it's much cheaper here installed appliancesdirect.co.uk/hel…ner
16th May
That would be a ElectriQ which I would highly advise against in favour of a better brand. You'll get a better overall system, and after service support.
16th May
My reading of this is that you would need to have an electrician do the electrical before hand. That makes it pretty hard to work out if it's a deal as otherwise a normal contractor would include the electrical work and the gas engineer.
16th May
Ours didn't need an electrician, we have 4 units in our home. As gambiting mentions above, these are pretty low power usage and can be run off a standard socket. You do obviously need an AC installer though.
16th May
With the fluctuations in the weather I would recommend getting an Aircon although we used Panasonic I can't imagine the difference is significant
16th May
Panasonic beats Daikin hands down for reliability and (for installers) after sales support.
16th May
Not sure how good the deal is we had a couple of Mitsubishi units installed in the bedrooms a couple of years ago by a local company, we got quotes from 2, the one we didn't go with wanted £2,500 for both units, the other we went with was £2000 for both units - they both spec'd exactly the same hardware which made it an easy comparison. I've had no issues if i've called for servicing - not had any issues with anything apart from mice stealing some of the insulation off the exposed parts of the pipes - the joys of a rural location i guess.

Great for cooling in the summer (If we leave the two bedroom doors open it will cool down the whole house (Bungalow) pretty quickly, also good in the winter when you only want to heat the bedroom rather than stick on the central heating. The heat is much more instant with the air con units.

The wife uses them on the dehumidify setting too if she has clothes drying in the winter (Cheaper than the tumble dryer)

Being able to get a good nights sleep in the few warm days each year is worth every penny it cost us!

I'd imagine if you have solar these would be even greater value if you can run the cooling off the sun....
16th May
Is that "Mitsubishi Electric" or "Mitsubishi Heavy Industry" ?
17th May
Stupid question, do we need council permission to install air con units?
17th May
Presumably yes if you live in a council house, but no if you don't?
16th May
Why wouldn’t I go with 3.5 kW unit for only 10 quid extra?
16th May
Zero reason - they're inverter driven, so only provides the cooling duty that is required, and not going to draw any more power than required.
16th May
3.5kW for an extra tenner
16th May
Hello experts

Could anyone kindly briefly explain how this would be installed in a front/street facing bedroom? Does the piping go from the bedroom ceiling, through the loft, and then out the back/side of the house?

we live in an end of terrace.

thanks in advance!
23rd May
Your assumption sounds correct. It's similar to how mine was installed. Given yours is end of terrace piping could also be run along the outside of the house.
16th May
what is your opinion on MHI? I have a SRC35ZSP-W 3.5kw. Almost two years old, installer came out yesterday as compressor is making a bit more noise than normal once it gets warmed up. He is going to monitor and if it gets worse, will replace under warranty at end of summer when year 2 service is due. I got a 3yr warranty with it.

It does one bedroom. I am keen to do my other bedroom and lounge on a 2 x system going to one condenser.
I see you mentioned earlier about Panasonic being a good brand. Just wondering what your opinions are and which would offer the best warranty options? Also, rough ideas on cost? My existing MHI is first floor second bedroom, wall mounted condenser on the side of the house and around 1.5-2m of copper pipe.
To do the other bedroom and lounge would involve more copper and power cable and I would prefer to get a new power socket installed by an electrican than use the existing outside one my current AC uses. I have other circuits available, such as kitchen which is directly below the bedroom, would rather spread the load a little bit.

Would really appreciate your thoughts if you have the time. I see you are in Lincoln, I am just south of Cambs so slightly too far for you sadly.
16th May
MHI is a great budget option; I have had very few issues with the ones I look after, although I don't install them. As a budget option, you get the pretty standard 3yr warrantee, but there will be support after that comes to an end.

Panasonic is a premium brand, and comes at a higher price point. Depending on what program the installer is part of, they can come with a 7-year warrantee.

I do feel, as an installer, that there is a noticeable uplift in quality.
17th May
Prices of installed split systems are a bit steep.
Anybody tried to install AC by himself and then get GAS engineer for finishing touches and certification?
23rd May
I did look a few years back and most wouldn't touch any budget systems and those who would think about it wanted near £1k for the pleasure. There are DIY systems out there now which use CO2 or propane as the refrigerant rather than R32 which means you don't need to be F-Gas certified to fit. It does mean they will be a bit less efficient but you'll probably save more on the install costs.
17th May
How long can the pipework between the internal to external units be experts? And does the length affect performance/efficiency?
23rd May
According to the data sheet the maximum pipe run is 20 meters. Anymore and more refrigerant will need to be added to the system
16th May
For the 10 days a year we have a summer its not worth having. Just sleep under a sheet those days. I think you would get more use out of a hot tub.
16th May
That's fine - then it's not for you. For me, having cooling has meant a comfortable environment, as I really do suffer when temperature and humidity starts to rise; so much so it effects my daytime and mental health. This is especially true at nighttime - I couldn't imagine life without AC in my bedroom when we went through the 2022 heatwaves, and last year (a standard UK summer) was on far more than 10 days.

In any case, it's also a cheap source of heat - far more efficient than Air To Water, so not just for summer.
16th May
Congratulations on your 1st deal
18th May
When you think how much this unit costs to run and think of the US size of homes with there combined heating and a/c systems, with some states getting extreme weather, lucky their energy costs are so much less than us.
18th May
Worth noting that running AC in cooling doesn't actually provide any substantial pressure on the grid (or at least, a grid that is set up for allowing for the heights of Winter). Cooling takes a lot less energy than heating, so will be nowhere near peak loads during colder months. Further, because of their function, is actually taking advantage of the solar panels during that time of year.

And this becomes the further we progress towards "net-zero" the less running AC will make any difference at all, because all energy taken will just be excess not normally used (but required for colder months)
16th May
It's been said on here that this is no good for any room bar a bed room. I have a 2.5kw Mitsubishi Heavy Industries (£920) in my lounge and it's perfect. Lounge is about 6m by 4.5m. Will heat it up within no time at all.
It's a little nippy now, so rather than put the underfloor heating on we use this all the time. Even the company selling it told me to go for this as opposed to the 3.5kw.
16th May
Every scenario is different, and can't argue if it works - installers have to make a sound assessment based on nothing being in pace beforehand. Should also note that a correctly sized system works efficiently, whilst an undersized system may work, but harder and be less efficient.

Above all, somebody needs to see your house and room to make that assessment. I very rarely install 2.5kw systems other than in bedrooms because the price difference is small, and rather go that bit OTT to be sure the end result is a system that works.
16th May
Why is this so expensive in the UK?
16th May
In the continent Air Conditioning/ A2A Heat Pumps are far more prominent, so a there is a larger competitive market driving prices down.

Installers are also more of a premium here because of the lack of us
17th May
They are selling Diakin Perfera for £2000 without electrician which I would say is not a great deal. I recently had one put in my bedroom (2.5kw) for £1500 and the electrics (fused spur outside) was like £80. So worth looking into local installers. Life changing though for sleep quality - my bedroom was 28C without the air con on just a couple days ago (south facing well-insulated new build...)! Death!
17th May
Where are you based? Just wondering if your local guy is local for anyone else at that price.
17th May
I installed a ElectriQ 18k BTU myself, as I had to use a pump for the water and bought longer hoses to connect, it cost about £700 all in. Paid someone to vacuum the system and add some gas taking the cost to £775.

The brand isn't as good but it has been working fine for 4 years now so if you don't mind a bit of DIY I would look at going down that route.

Remember the one on offer here is 9k BTU which is half the cooling of what I managed to install for £775

For anyone like me who was wondering...... I already have one unit and my outside condensers to be up high, above head height on the side of the house.
This deal DOES include a wall mounting kit which is helpful to know.

The outdoor unit can be sited on rubber blocks at ground level or on brackets at a maximum height of 3 metres. Rubber blocks or brackets are supplied where required, within this package.

Also, note that outside trunking is NOT provided. That is annoying as it looks much neater with it. It looks as though the condensate pumps would be included in this deal if needed which is good.

The five year parts warranty is impressive. A good deal, I am tempted, just a pain to have to get a sparky in first to get a power point put in. (edited)
17th May
Depends most installers for up to 5 kw can come off a spur if close to condenser or worse case wire the unit from inside to out power wise there’s many ways of getting power to it .
16th May
I'm guessing that these types of heat pumps are not covered by the govn £7500 grant as installers would then be providing good value, air to air would suit us as we don't use hot water and awake to a cold shower even in winter.
16th May
Air to air not covered by the grant sadly.
16th May
Wow, 1.5k for a single head. I got quoted 1.8k for 3 heads and 27000BTU aircon including install from aircon direct. (edited)
16th May
If that is ElectricQ, then good luck with that. The premium paid for better branded systems is cost-effective over the lifetime of the system, with better guarantees and aftersales support.
16th May
Sorry if a dumb question, but are these reasonably quiet?
16th May
Outdoor or indoor?

Outdoor is best described as silent; they "wind up" when there is a high demand, but even then you'll struggle to hear it unless standing next to it.

Indoor noise is subjective but is adjustable, and something you come to live with without noticing.
16th May
I've got Toshiba ac in our bedrooms. I need a small unit for a 2.4m x 4.8m garden office. Aircon direct quoted me £1400 odd. A really simple job too and I have a feed right next to it from when we sold our hot tub
17th May
There are all-in-one units that mount on the wall and need two large holes thru the wall but vast price increase on them, around £800 on ebay, can DIY as gas is already inside it and sealed up.
16th May
Had a Samsung windfree 2.5kw installed for £1200 earlier in the year, so I would say this is fair but not great. Also mine came with the mounting kit, the outside wiring and the ducting. We have a s/west facing bedroom so super hot in the evening in the summer. Actually used it a couple of times for heating during the cold January/February as much cheaper than heating the house. First use to cool during the heat last week and it’s way more effective than the fan we had. It is a luxury in the UK for sure but in my opinion worth it if you can stretch to it.
16th May
Where did you get that from?
16th May
I was looking for something for three rooms. Lounge and two bedrooms. Any suggestions on what I should go for and any suggestions on companies to use for installation?
16th May
Yo experts,

Where would the outside bit for this get installed. Woudldn't want it on the back of the house overlooking the garden as its an eyesore, but not sure if your allowed to have it attached to the side of your house semi-detatched, have a parking spot next to the side of the house).

Or does it sit on the floor? Am half tempted. The "portable" one we have is a godsend but lord christ it's loud. (edited)
16th May
Can be wall mounted.
16th May
"Service AreaPlease Note: At present we can only offer this service within a limited area. We will look to increase this radius in the near future. We can currently cover the following counties: Bedfordshire, Hertfordshire, Buckinghamshire, Cambridgeshire, Northamptonshire."

Is this deal national ?? (edited)
18th May
I think these are the only civilised countries that have mains electricity and running water
16th May
Great deal. Daikin are top notch and the installation team is really good, at least it was when I got a couple of Daikin Perfera in 2022. Note that you need the 16Amp (or higher) power supply connected to a weatherproof 4-pole rotary isolator within 1m of where you want the outdoor unit to go.
16th May
Presumably this is using whatever cheap contractor Costco have managed to sign up so install may vary.
17th May
I never wanted one but after reading comments I think I want one
17th May
does this dry your eyes out like every other AC in the world
17th May
Yes it will lower room humidity from the room but the majority of people's eyes aren't affected.
Ps. As an aside, Daikin are good units (edited)
17th May
I have a Fujitsu one that does heating cooling in my home office studio. It has been excellent and is wifi enabled. So the AirStage app on my phone gives me the temperature and allows me to control it from anywhere internet. It also makes it easier to set up schedules.

Although with inconsistent weather I prefer to put it on manually. So 30 minutes before I walk down the garden to it.
19th May
Nice, what's the construction of your studio - brick?
