Or only installed in the right situations.

Make it an insurance backed scheme - the premiums will be so high nobody will do it and the message will get home. Possibly somewhat cynical and, given we now broadly agree with him, you may think of it as a good move. I guess I have no problem with him backing what I think long may it continue.

+1 to that. To turn this over we will need more than education because we will be up against capitalism, not a bad thing in itself, which will need careful control if @ProDave's prediction is not to crystalise. As a for instance we could regulate the installers in such a way that they have to guarantee, and pay any difference for the life of the system, the energy input and performance of the house once installed (EG Kw in for 20deg inside at 2deg outside with a wind speed as well.) That would force them to get educated to ensure they put systems in that work and very quickly HMG would realise where this does and does not work in terms of homes.

I guess we are all entitled to change our minds when we discover we were wrong - some may say it was big of him to admit it and move on - I think it is called integrity.

and be prepared for the electric bill! Although you may be able to sell the de-ionised water you will get.

Planners accept a vast array of detail in drawings from Sketches to full blown architects drawings and 3D walk throughs. The things they need are the principle dimensions so they have something to refer back to. In my experience around here they don't even need drawings of consistent scales but the dimensions written are what they take along with relative features of the drawing. So if you show the top of a dormer as below the roof line but put a dimension that would make it higher than the roof line then the drawing not the dimension stands when you build it.

2.3 should be fine, 2.4 used to be the base minimum but now there is no minimum and 2.3 is only 100mm less. The room shapes with be something of a factor. A large room with a low ceiling is more of a problem than a small room with a low ceiling because of the way it feels.

That's the whole idea then!

If you have a signal then it is likely you can get a better one by using a modem with an aerial and / or directional aerial. This one HERE is not massively expensive but has two sim card slots so you can be connected to two providers giving you more certainty of connection. Obvs that means having two accounts but I have an unlimited data 4G package from one of the big providers at £32 PCM, and I find it works very well I can work from it without a problem. Also as we are all with the same provider I can gift up to 100mB a month to my family which works well as they have limited data but I can top it up for them. It does mean we are on the same provider though which is all eggs in one basket!

So you need to work on how to get the views with the minimum of glass or go for high end glazing which may be up to quad glazing and so will limit the light entry somewhat while having good insulating properties. Also remember that the frame of the window is the worst area for heat loss (Sealed unit 3G glass is usually better than the frame) so the more frame you have in proportion to glass the worse the heat loss is U value of the window (Uw) is . On the south side I might try to make the kitchen - dining - living wall more glass to get me some more solar gain and reduce the floor to ceiling glass area (perhaps by having low walls with windows next to the doors). Naturally we cannot see the shading that this wall might have.

Looks like a lot of glass on the north side!

+1, the challenge is realise the difference between the old and the new. Right now, as I would out how we adjust things here at millstone manor for the new electricity price of 21p (We cannot switch for reasons I won't go into but it is not anything we did) and the fat that our LPG contract ends in about 8 weeks, I know I could add a few 100mm more insulation in the loft, we have 300 already, and save a bit but it may be that switching to ASHP but keeping the GAS for DHW or doubling the HW tank capacity (we cannot use a COMBI as water pressure / flow rate is too low) and using the night rate will help as long as I disconnect cap ex from revenue!

They are not good for much but if we fed all the designs for heating systems in and found a metric for measuring how 'good' they were we could get our AI to validate our design in the same way they validate a road sign in a self driving car - classifying is what they are very good at.

I wonder how one would one go about designing a COMBI ASHP for a passive house without a storage tank. IE tiny heating load and relatively large DHW demand from time to time? Two ASHPs!

If the process encapsulated this then why is it a problem. Perhaps an AI could do it?

As you say if common load then it drops out of the equation the problem is that heating load of the building is only one dimension of the requirements, the other is, often, Domestic Hot Water (DHW) and this is where the two heat converters seem, to many, to have different capabilities - IE the combi principle

Nope its just an energy converter like the gas boiler!

But why does this need paying for surely its pretty simple, perhaps we could work out a straightforward process that would lead to a verifiable design and close the loop.

Aspects of this are not quite true. True it will fade, its a powder coating, but it is not true it cannot be repainted although it does take careful preparation, not easy because of the nooks and crannies in the extruded sections, and the right paint, epoxy based is most reliable.

How if it is fed from a ring without a timer? Looks like the call for more info is pressing.

Me too - but not seen that before.

So it can be range "In Italy, Poland and Russia, this notation is sometimes used in engineering to denote a range of values." Wikipedia. The windows are Polish, in origin, so that makes perfect sense - good spot @SteamyTea every day is a school day!

I am fitting some FAKRO windows and they state a couple of dimensions as S + (3 ÷ 5)cm which I would normally take to mean S + 0.6cm (6mm) but other bits of the instructions tell me that I need a 20mm gap and I only have 6mm. I guess the good old Obelus (the ÷ symbol) must have other meanings that I am not familiar with. If I take it to mean 'between' or 'to' then everything seems to work out. Anybody able to confirm my understanding to save me getting on the manufacturers tomorrow.

Some of those stats make interesting reading... over the last 10 years or so the number of residential applications granted has been roughly constant at 75% (ish) it gives the impression of a target. That means 25% or so have not! Similarly the agreed time limit stats which show around 87-88% being done inside the time limit reliably across the last 6 years (Stats prior to that look odd - so assume that the planning portal implementation may have glitched it or some such). Again 12% get delayed. Given the both stats are broadly flat over the period the implication might be that there is no pressure to improve either and so the local planners may have unconscious approaches to maintaining them. So although you expect your application to be granted and in the required time they know that there are some that won't be and there is no pressure on those that are not so long as 75% are granted and 87% are done on time.

Its a systems thing - you squeeze it in one place and it pops out in another. People have gone from thinking now is a good time to start to thinking that now is not a good time to start, probably loads of reasons. Materials shortages, sky high labour costs, spent the money we saved in lockdown, this new normal way of working from a remodeled home is perhaps not all it could be, 'what they want me to back to the office' - what's the point of remodeling, too much hassle. Upsides are: the planners have more time to look at and process applications, the sky high prices will drop as less work about, the material shortage will go away as less demand, oh and commuting was not so bad after all. So relax just put your application in and keep on keeping on.
