@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.

Heat Geek already has the Pro on offer now:

  • even more quiet than the old ("current") Plus
  • packs more power per size (L-shaped evaporator), but less to select from
  • has a mode where it keeps the fan idling if there were any R290 leaks to reduce clearance requirements (the German new Plus has that, too)
  • Plus in June confirmed as well

I wonder whether that lower noise could make a difference where the ODU is installed in a gap between two dwellings?

I had a go at using the MCS calculator for the Vaillant plus 7kW VWL 75/6, assuming it will be hanging away from the ground (I assumed the barrier would be the wall of the neighbour; is this how it should be filled in?)

Firstly check you are using sound power not sound pressure.  Some manufacturers arent entirely clear and both are measured in dB(A).  From memory the sound power of the current Vaillant 7kW is 55dB(A) or there abouts (I forget exactly).

Assessment position is the most affected aperture (window/door) on an adjacent property (if there are multiple you must do it for all).  Normally the nearest but not always.  You can ignore kitchens (solely used for cooking), utility rooms, stairwells, halls, bathrooms, only 'living' rooms and bedrooms count.  You dont have to calculate the effect on your own property!

Reflective surfaces are any hard surfaces within 1m.  So the minimum possible is 1, unless its cantilevered >1m out from a wall and > 1m from ground.

A barrier is one between the ODU and the assessment point, not one at the assessment point.  

What else is unclear, full and authoritative description as referred to in planning legislation here
