To be honest bud I think you'd be thoroughly disappointed in that content. Uk Manufacturers are generally just sales branches and pretty clueless imo. They do have hidden gems ofcourse.

@@HeatGeek Just the hidden gems would do.👍👍

@@HeatGeek in most tech spaces in the UK the structure tends to be that the UK entity buys the kit and sells it (usually to distribution) for a commission. This allows the manufacturing location to ‘manage’ the local UK profit and therefore how much foreign tax is paid. As you allude to, this is often packaged with ‘need to know’ levels of technical product knowledge and also very limited access to software and firmware details. As the software and firmware is the core of the competitor edge this is hardly a shock as security is key. Hence UK tech support staff are often really more marketing and simply can’t answer deeper questions. Both V brands are examples of the latter (my opinion and no offence to the local guys who only know what they’re allowed to know).

@Steve Chambers absolutely bang on 👏

@@stevechambers8869 Vaillant has apparently just opened a heat pump factory in Belper, not product development but must have some techs with deep knowledge, and if you include ground source Kensa are wholly UK based.

That was very nice to read this morning. Thanks 😊

Solar matching is very much the future, run longer on low power (for free using excess solar) during the day to pre heat the house reduces the need to run flat out during the evening demand peak with everyone else.

Hello, you need to contact an installer, the issue we have there are only a few so does depend on location. As long as the installer has an account with Daikin or one of the wholesalers they can purchase accessories if it is still available.

…it’s more like +12 months lead time, in Central Europe….

@@adrianbotos2819 Wow! If it gets further delayed I think I will cancel and try another vendor like Viessmann, or are they all the same?

Viessmann and Vaillant are the same (8-12 months). But that is in Hungary, Romania. I dont know if in the Uk the situation is the same. I know Panasonic has ussually on stock Ashp.

Ammonia R717

@Clip the Apex are you saying that's the most efficient? Or you'd like more info on it?

@@TC-V8 As far as I know, an overall best for the time being. Has the best enthalpy over most refrigerants, it's natural so 0 ODP and 0 GWP. Runs at lower pressures than the HCFCs, CFCs and most HCs, which is important when it comes to running costs (less pressure, less power consumption) The problem comes with it being toxic and flammable.

Daikin make one called a "multi plus" the efficiencies aren't as good as either air to water or air to air.

@@Macro_Abuser That isn't the UK market specific model due to be launched?

@@avivscrewvalla Not going to be released in the UK anytime soon. Plus it is only any good for a 1-2 person property (small hot water tanks only). Yes...I was VERY interested as well!

About half. Yes it will reduce your efficiency alot unfortunately. Always listen to the engineer.

If it does increase then i now dislike the modoka unless you can set min run times.

@@HeatGeek I had the same issue (works more like on/off but uses the weather curve) via Octopus Energy Daikin A2W HP install in Sep. 22. on a complete open system comprising large rads and ~450m of UFH pipework (Octopus also removed UFH blending valve and UFH pump 👌 - I had already removed all UFH controls and actuators). CoP was still pretty good to be fair however. Moved to pure weather compensation, and I would say runs longer and is weirdly able to modulate a little lower (run at lower minimum power draw to the HP). Trade off is zero room compensation/modulation, so for installers where users will not want to/be able to return to adjust weather comp. curve, this will likely work "better". Can now just adjust flow temp +/- 10C (moving the curve up/down) at any point. There are weird things on the thermostat like turn up the temp by 0.5C (where existing measured temp is say 20.5C and previous target is 20.5C), and the HP goes off!! Had to "wait until room dropped to ~0.5C below setpoint before HP kicked back in again. What is that about! (hysteris is too brutal/harsh would be my guess)

@@stephencrown82 How did you find Octopus for installation. I've had a survey done and am considering the quote. Just wondering what your overall experiance has been.

​@@richardpacker7514 Pretty good on the whole. Very very good on price. Really nice people, prompt, good communications. I had a 2018 Mixergy cylinder, and they ultimately allowed me to keep it (rather than replace with a Daikin) and integrate. They were not prepared for this at install time, so this was a let down, but got sorted in the end with Mixergy helping out. Believe they should know what to do now as I think they've done a few now. Really poor insulating of external pipework (including clipping the pipe to the wall *before* insulation, meaning they cut the insulation to bits to get round the clips!). I re-did this myself, but I could have reported this to get sorted, and other people should. Heat loss calculation came in way too high (from my own measurements), meaning initially a higher output heat pump was chosen, along with higher flow temps (~5C higher on the curve) than needed (they did leave the config in weather compensation mode with room influence and a 5C +/- modulation of the flow temp, so likely mitigating the higher flow temps mostly. They did remove all controls, zone valve, mixing valve and dedicated pump for the UFH (brilliant and as per Heat Geek design guidance best practice), but let themselves down as they didn't adjust/check the balancing of the loops (or rads in the house), so I balanced it all myself! They also didn't put a Low Loss Header/LLH or Buffer, but instead put in a Volumizer on the return - again a best practice to avoid higher flow temps needed for buffer/LLH I've no doubt a "Heat Geek" design and install would be better (no-one in my area anyway), but its probable that the law of diminishing returns will apply, and would likely be higher price. A few months on, things may be better to be fair, but I would go in with "don't let perfect be the enemy of the good" mindset, and understand a big company approach they are scaling up for deployments will have limitations, drawbacks

@@stephencrown82 Thanks for the reply. I really need to do my own heat loss calculation to double check theirs. I'm also going to be improving the insualtion in the floors better windows etc over time so need to factor that in too. Really intersting you've got a Mixergy cylinder as I was going to ask them about using an alternative to their quoted one. How do you find them (Mixergy) seems like such a good idea don't know why I wouldn't go for one. Is there a way to find you online would be great to carry this conversation on off KZfaq if possible.

Almost the same, it's only equipment improvement that make the difference but you would only likely be small, it certainly wouldn't pay back to replace it. But 16 years old I'd certainly start putting funds to one side to possibly replace in 4 years or until it fails.

You can, it would be easy to pump it, this can go through a plate heat exchanger, so vented stove side with a heat dump (other methods available). A system pump and a interlock to stop the heat pump. A clever buffer with certain tappings at certain heights is also a good idea for distribution, twin coil tank, one for hp the other for the stove. Hope this helps.

@@wobnoway5692 Cheers mate for the response , grateful for your advice and expertise. Will probably get a schematic layout drawn for my plumber to setup this as he is modern day plumber that doesn't like back boilers or boiler stoves Thanks again !!
