@majordennisbloodnok Err… sorry Major? Your service agent cleans your heat pump casing for you?????!!!😳

Yup.

Not only, of course; plenty of other bits too. I have mentioned them in positive terms plenty of times before on the forum, so that's just another minor hint at why.

@majordennisbloodnok Daikin, take note! (In fact, I have switched my allegiance for my next service) but, I did think a reputable manufacturer would have been reliable! Toodles.

Does anyone else think that the "Pro" is the previous generation Plus in black? https://www.vaillant-group.com/news-stories/vaillant-at-the-ish-2025.html

@marcexec I did look into this black version for my new heat pump.  There is a german spec, reading between the lines I felt it's much the same as the current machine (but I am no expert).  Specification from page 47.

@trebor12345 

Thanks for this.

@marcexec I scrolled through and what sticks out immediately is the extent to which they have shrunk the R290 protective zone (pages 13 on).  I think its also about 3dB quieter.  So they are different. 

They advertised in early blurb new control electronics reducing the number of separate control boxes, I cant immediately tell if that has been realised.

Installer says they're coming in April. Haven't seen this mentioned elsewhere.

So it will actually be available in June, which fits with what Vaillant originally told me last year.

Vaillant is one of the heatpump brands that we are considering. The downside seemed to be the baseline controls were too simple, so I am wondering if this could change it? 

We are not looking to have different temperature in each room, etc.

The Vaillant controls are excellent IMHO, possibly some of the best.  Why do you think they are too simple?  What do you want to do that you think that they cant do?

Oops, I missed your reply..

And I may have got the wrong impression from posts I read a while back! 

For heating, all we should want it to do is to be able to use wc with an external sensor and work as a programmable thermostat with different temperatures for different times of day and also vary by weekday (not necessarily for 7 days, but some flexibility). 

For the hot water, I am thinking we will need to be able to set the target temperature and times of day we will need it to warm the hot water tank to it. And the legionella cycle of course. And to be wired in, without dependency on the cloud during operation. 

And also have the usual holiday and all day mode..

Ideally it would also provide some state on overall consumption, etc. 

I am wondering if the default controls that come with the heatpump would suit or would we need a specific option..

The vaillant controller and app do all of that (and more) natively.  Forget any external controller it's just not necessary.  Seriously you don't even need (and really shouldn't have) a thermostat (and if you need one the Vaillant wireless controller has a temperature sensor).

The app is cloud dependent but you don't need it for any of the above other than easy access to consumption figures (they are available locally but it's not quite as easy).  

I use do HA to get plots of various things for interest, but not for any control which is done purely by the local Vaillant controller.

Seriously you need nothing other than the valiant controller to control, plus ha if you want fancy graphics to monitor.
