Brilliant Video, I design systems using this kit as I'm a Cad draughtsman's / engineer for a HVAC company, you have such a informative and down to earth way talking through the system, and its refreshing for someone like me that don't get hands on with the kit itself!
Thanks for the video it amazes me how so far ahead you guys are in the UK compared to North America in the whole energy savings systems. There was a point when Daikin was selling Altherma units here in Canada then stopped because of the lack of understanding of how they work. Those system are not for the faint of heart and are very technical. I would love to come over to the UK and do some training on those systems. The market here is wanting this kind of option. Thanks again.
Thanks for your comments. It’s a shame Daikin stopped the Air to water range in Canada. It’s a great product and once you get your head around them, their not much different to a boiler to be honest. Thanks for watching and free feel to share, you never know, you may create an interest and Daikin may start supply to Canada again. 😀👍
@@ecobubl That would be a great Idea only problem you are 50hz and we are 60hz. If you can get 60hz its would be great. Where I live there would be alot of interest in doing these systems just need to educate the consumer. Thanks take care.
Here in Finland all new houses and significant part of the older ones are equipped either geothermal or air source heat pumps (if district heating is not available). If and when a new house is equipped with ac unit/mechanical ventilation then a heat recovery unit is mandatory. Heat recovery is becoming more common also with waste water systems. Oil is taxed to the maximum.
Propably because energy costs are way higher here (I'm from The Netherlands, bit more expensive than the UK I believe). Those systems aren't that technical though. Many hobbyists install their own, as did I (not Daikin but Panasonic).
If you have a gas boiler with an indirect tank already, installing a monoblock heat pump is simple. There is nothing terribly technical about 2 water lines, 2 antifreeze valves and a 240 volt power supply. All of your existing pumps and piping can still be used. The problem in Canada is the government is technically illiterate or they would promote this technology. The 240 volt, 60 hz, compressors for R32 already exist from several of the top tier manufacturers. The only large monoblocks that you can purchase in Canada are R410 and are less efficient and have a much higher GWP than R32/ R290 or R744.
Here in Macedonia , it's quite expensive for our standard to implement heat pumps. I got a quote on Daiki Altherma system for 200m2 and hot water around 15,000 euros.
@@ecobubl Superb retort young lady, told My wife who roared with laughter and is full support. Being married to me, a gas fitter, she knew exactly where you were coming from, best wishes.
Nice job! I'm getting this heat pump installed but with the Daikin HW cylinder, also having my gas supply capped off at the same time and looking forward to being a carbon neutral household.
We have a 2500 sq ft house over 3 floors, good airtightness and good insulation. We have underfloor heating on ground and first floor and radiators in the attic conversion. Any idea approx what size heat pump we’ll need. We are thinking of a daikin air to water heat pump.
In the outdoor unit the 4 wires are connected to X5M to pin 11, 12, 15 and 16. However I am not 100% concerning the pins in control panel. If the panel is open there is a green part with 4 points to connect the wires. I think the 1 pin is the lowest one then the 2nd, 3rd and the 4th. It is shown on page 65 left side in the manual.
Out of interest why do you need both a 3kW "immersion" heater in the sunamp and a backup 3kW heater in the heat pump. If the heat pump does not function (I presume in very cold weather) - isn't it more efficient to run off the sunamp heater directly? Or is the backup heater just for keeping the water flows defrosted in the heat pump?
Hi, You didn't appear to do anything about managing condensation - no soakaway. How confident are you one isn't needed? We're having a 3M installed soon(ish) and groundworks isn't part of the contract so I need to arrange a soakaway if they're required. Thoughts?
What thread size for service, such as evacuating and filling with refrigerant is common for this Monoblock with R32? Split air conditioning systems have 1 service connection, which is 5/16 inch. But that is quite sufficient. Is this also the case with this R32 monoblock?
The flow temperature needs to be 58dc, the heat pump runs for 45 mins and then the internal immersion heater kicks in and takes the battery temperature to 65dc, so these batteries are now suitable for the R32 Daikin and Samsung heat pumps.
very interesting and informative video ! Antifreeze valves are new thing for me! what stops to drainage all the system??? And how does the system fills up with water when antifreeze valve closes after ambient temperature increases ?? Via automatic valve or ... ? And secondly - why do you use flexi hose???
I have been installing heatpumps for a while. I did think it was bizarre that the older monobloc prepiped cylinder had the buffer on the return but I guess that's just a volumizer for the defrost. Kenza say to pipe the buffer with 2 pipes across the flow and return. Do you install buffers on all underfloor systems because of the flow rate and zones shutting down?
Hi Mike Yes if there is another pump on the UFH manifold that could pull water through the heat pump, then you definitely need a hydraulic break buffer tank. Think it’s best to use a 4 port buffer on most installs, you get great flow rates and high efficiency
@@ecobubl I've just had my first 2 Altherma monoblocs and was a bit annoyed that all the wiring has to get dragged out to the heatpump, wish they had a indoor board as a option. Plud Id rather run a larger cable for the backup heater and compressor, seems daft. Other than that it looks great and plumbing side is fairly easy.
In my country Daikin instillers telling me that they don’t put buffers any where that they instal pump? How is in Poland and your experience? Isn’t that bad for short cycle for compressor? Thx
I thought the Sunamp needed a flow temp of 65deg to recharge and that the Daiken couldn't provide that. That would mean the Sunamp would only charge on direct electricity which would be dear. Am I worng and if so what is the flow temp for charging?
Hi Yes really great product, very fast heat up times. Defrost mode is a little louder. I was disappointed with the sound level compared with the Daikin HT, which is so quiet Many thanks for watching.
Hi, is it possible to have a multi zone set up with this heat pump? Ideally i'd like two regions on thermostats that allow me to turn different radiators on / off - or would this heat pump work with smart TRVs?
It would be practical and easier for installers if manufacturers integrates a separate circuit for DHW cylinder without having ESBE valve as that can be way too complicated . That can also be used as defrosting cycle for ASHP only going by my understanding how this equipment works 🤷♂️
Thanks. Maybe you can explain why a 25liter buffer-tank is necessary with underfloor-heating ? With underfloor-heating the temperature should stay high enough to defrost the heat pump ? Or am I wrong ?
if you have pumps on the under-floor heating manifolds, you need to install a hydraulic break, if not the heat pump will fault on CO fault, it thinks the internal pump is running when it shouldn`t be. You also need a minimum 20 litres of water volume for defrost mode
The ESBE valves give you more flow rate through the valve compared to a standard zone valve with a ball joint inside. it also stops heat leaking into the heating system, as the valve is totally sealed shut. Daikin supply them with all heat pumps.
Yes, thanks for the video. Like many, I'm now putting effort into researching heatpumps, heatstores and etc. Watching your video over morning wake up coffee one thing that jerked me awake was the poor construction of the Daikin heatpump casing. Scotland is wet and I'm 30 miles west of Glasgow so not really in the worst of it. When you removed the casing to proudly show off a couple of electronic boards my first and only thought 'well that's not going to last one week here'. Just had four dry days in last 4 weeks and boy! it rained. Global warming is here - we know this. That Daikin casing is unsuitable for driving rain and for an electrical unit designed for exposed external installion it is rubbish. I'm wondering how it got type approval. No worries - early days yet. Good equipment will come along. Liked your video !!!
They seem to fare ok here in Finland, and we're no strangers to rain here either. Not to mention snow, ice, sleet, temperatures flailing above and below zero... ;)
Hi. I’ve just installed the 11kw version and just curious how people are finding its performance cost wise? This is my first heat source pump and have just cut off my gas to the house so this set up needs to work and help me save money (and planet) but so far the running cost seem pretty high:(
@@ecobubl hi there and so appreciate an answer. I have TADO SRV’s for rads upstairs and HEATMISER room stats for downstairs UFH. with regards to hot water I’m scheduling the water at night when OCTOPUS ENERGY are 5p a KW but I think I discovered today that if outside it’s zero degrees outside or lower the heating will take priority and therefore I wake up and the waters not heated up!!! I had a 6 yr daughter and 10 yr disabled son so this scenario isn’t great:)
@@ecobubl I have a daikin EBLA09 and currently have a hive thermostat controlling a heating pump which switches a relay to turn the heat pump on. This wiring was actually taken from your video. My question is are you finding any better way to maximise efficiency. I did try the moloko thermostat but couldn't really get on with it.
you have 25 l buffert tank , is this standard because i read daikin monoblock wants 100 l to have a good run or whats the number or how do i know how big buffert tank i will need? size of house, floorheating? kw on pump?
Hello, Since 2 days I operate the daikim Altherma 3 M. Concerning the settings, I have 2 questions. Is there a setting to limit the compressor starts in 1 hour. Is there a setting to limit the flow of the water to 20 or 15 liter per min. At the moment the flow is about 28 liter per hour. Thanks for helping
Hi Martin You can’t limit the compressor starts. You also can’t limit the flow rate, as the pump modulates accordingly to the require flow temperature. Cheers
@@ecobubl yeah theyre for refrigerant but from the look and the tool its pretty similar, ill guess the only difference are the o-ring materials which on ZoomLock max would be HNBR or other material meant to handle refrigerants
@@dganatra11 sorry didn’t explain. We sell monobloc heat pumps (everything is external) or split units, where you have an outdoor unit and an indoor unit. The small monobloc units 4kw,6kw &8kw are up to 25metres between the cylinder and outdoor unit, the large monobloc 9kw,11kw,14kw and 16kw are only 10 metres between cylinder and outdoor unit. The split unit can go 30metres between indoor and outdoor unit and then 10metres from indoor unit to cylinder, thats for sizes 4kw,6kw &8kw. The larger split units 9kw,11kw,14kw &16kw can go up to 50 metres between indoor and outdoor and 10 metres from indoor unit and cylinder
Thank you, once again, it's clear now. If the large monobloc is installed at a distance of approx 20mts from the hot water cylinder tank, would it be detrimental? I would like to know if it's ok? Look forward to your thoughts.
@@dganatra11 that’s Daikins specification, the problem you will have is flow rates to the cylinder, pipe work should be 28mm from outdoor unit to the cylinder. If you don’t have the flow rate then the heat pump will fault during defrost mode.
Two further questions, if I may. I will be using the heat pump only for heating, not for DHW, and intend to incorporate a buffer tank. I noticed that you used a 25 L tank for the installation of the Daikin Altherma 3 M R32, I imagine that size would be adequate for my needs also. I'm concerned regarding the use of antifreeze valves. I will be constructing a small roof above the heat pump, so as to avoid any snow or rain collection. Furthermore, the pump will be on continuously during the winter months, hopefully, the continual movement of the DISTILLED water in the heating circuit to the buffer tank will obviate any chance of freezing. If antifreeze valves are essential surely the circuit could be drained, during the night, for example, and I wouldn't even know until the morning. Then there is the process of refilling the circuit. By the way, I chose the Mango heat pump partly because of the low noise generated, 42 dB at one meter.
Hello, I have the same plan, I also bought the Daikin Altherma Monoblock with 6 kw last week, I am also considering buying the 25 L or 50 L buffer tank, since the monoblock needs the buffer tank water for defrosting, I think that I take the 50 L variant!
Hello, I have the Daikin Altherma 3 M but there is a problem that I can not solve. The power supply of the compressor and the supplement heater is fixed at the machine. The 4 wires to connect the indoor operating panel is also fixed. If I switch on the power the screen shows the sw version it is 6.6.0 After some seconds the display change and shows synchronising the indoor unit. But nothing happen. How an I solve that problem. The machin is ok to operates no indoor unit. I connect direct to the floor to heat the house.
The machine comes with a control panel having 2 to round buttons to turn and press and between there are 3 buttons including a home button. I have in addition Madoka unit. Right now the Madoka is not connected to the system
@Mick G But you can get a 50% grant up to £6000 which helps quite a lot. Insulating/airtighting the building first so it needed a much smaller heat pump would also make a lot of sense (more expensive up-front but much cheaper in the long run). I did see a bit of PUR going onto the building in this case so it looks like they are doing some of that.
Hello this is Mike from Amsterdam Holland I'm a mechanical engineer just like you and yesterday I placed the same daikin for the 1st time in the Netherlands but now I've got a fault code u4-00. End daikin helpdesk Can't help me out the coat means there's no communication between the controller and outdoor unit All the wires are correct in functional do you maybe ever solution or can help me thank you
It could require a Software up date, also double check the voltages on X1M and continuity on the wires, you may have a break in the cable, or no neutral to outdoor unit.
@@ecobubl Yes I have all the 4 wires are connected correctly I can adjust to controller the time the date I can let the pump run to do his program and after the program is finished Denny pops in to default any says no communication with the outdoor unit End Daikin the Netherlands Don't know what the trouble is because it's a brand new Product here in Holland please can you help me???
@@ecobubl Hello no I'm using a 3rd party and I configuration in the MMi foreExternal control I collennan run is automatic air program and when then it's finished he will stop and say no communication with the outdoor unit order controller What everything works the display he says the pressure inside the system the temperature the only gets an alarm U4-00
Hi Andrey The back up heater is fitted to a lot of heat pumps, this kicks in when unit enters defrost mode and helps maintain the system water temp, it’s only on for a short period.
@@ecobubl Here in Finland they are equipped with 200-300 liter boilers. Heat pump benefits until -20 or even -25 celsius and those few even more frosty days it's constant defrost cycle/all electric heating. Heat pump covers roughly 95 % of the days yearly.
Hello again, I've messaged in the past, please could one of your team contact me. I like you to install an air source heat pump please. Regards Gary Gray
Oh you miserable bugger :-). OK it's a bit cheesy, but I don't think we should cavil about an attempt to add a bit of levity to what is an otherwise solidly technical video.
First let’s get married and make babies together. Then we can look at renewable technologies and maybe get a Daikin heat pimp thingiemajig and then do snuggling on our sofa in the modest overpriced warmth it provides ❤❤

Hi, I'm English but live in the Czech Republic. I need someone, like you, to install my heat pump, (Mango 11kw), and a heat battery which I do not have. This is a serious enquiry to have a technician visit, supplying the heat battery and undertake the installation for me. Please contact me and I will provide complete details. I would, of course, accommodate feed and pay for the flight.
Hi Geoffrey Thanks so much for your comment, unfortunately we wouldn't be able to travel to Czech Republic or supply equipment to another country, but thanks for your kind offer. all the best.
