Its amazing what you can do with photoshop or some AI deep fake system. Oh - I get it that's where the microwave came from as well - respect!

Bonkers or what!

Hi - and Welcome to THE forum for people like us.... This may be another one of those occasions where the designer has not understood your build ups correctly. To get an accurate calculation do what @Thorfun suggests. The spreadsheet is here: https://forum.buildhub.org.uk/applications/core/interface/file/attachment.php?id=62325&key=a181232df44762993cdfe81c623c7c47 I think..

There are loads of them at graduate level anyway. I am involved with three of them in Engineering across a range of large corporations and SMEs. The students need good A levels including Maths and the ones I know work very hard and are very capable.

Looks clear enough to me and it must apply everywhere because it points up what MCS must do and MCS does it. Have a look here: https://mcscertified.com/installers-manufacturers/becoming-certified/ It is very much a close shop there but any other body could set up to do the same thing and be able to certify.

Someone needs to draw up multiple cause and influence diagrams for this systems problem based on the discussions above. This whole discussion is, in the end, a soft systems problem.

Not sure this will do it. We need a better technical education system, properly invested in AND to change mindset about what is and what is not an acceptable profession for "middle Englands" (all other UK territories also) children.

This topic seems not have been mentioned much since this initial discussion. The several other places include: and So I thought I would poke it now as I have to decide on which circuits to fit Arc Fault Detection Devices (AFDDs). The 18th regs seem to mandate them on sockets in all buildings not just the tall ones or HMOS etc, as 'recommend' is to be interpreted as 'should' the way I read it. AFDD devices have moved on a bit in the 3-4 years since the OP and you can now get single unit combined double pole with AFDD, RCD and MCB for around £120 (I have been looking at those from LEWDEN but others seem to be similarly priced.) So if I put them on the five radial (we won't be having any rings) 13A socket groups I am into £600 and then I wonder about the 5A lighting sockets, these are sockets after all, but as they are all fed via a DMX dimmer it is not obvious how and AFDD might respond to such a situation. Anyone any thoughts to add to this question and the wider AFDD debate four years on?

That's a mess then ... The word 'Design' implies PI insurance and ISO 9001 (or equivalent) surely! Lets all get together on here and build an app that does the design, does not appear to rocket science, and give it away.

Shouldn't you be using frame anchors rather than going directly into the Brick work, you need to avoid splitting the bricks I would have thought!

Welcome to the FORUM for people like us... except I am no fan, as in I love to see it done but don't enjoy doing it, of painting, decorating and tiling so great to have your wisdom aboard.

Are you proposing a final answer to your original post or just thinking out loud here. No choice implies just that, no choice, but thinking out of the box might imply some choice at least and hope dies last.

Same with help to buy and many others, feels like a quick win to HMG for two reasons: 1. They can say they are actually doing something and 2. they ensure they put public money into the pockets of their core supporters. Why wouldn't you do it?

Sorry, I get that, no I meant exploit the science for their own ends by being selective, looking down the wrong end of the telescope etc.

which can be exploited for good and bad as well remember - many instances and it does not always agree with itself. (This is not to say I don't believe in most of it because AFAICS it is still the best understanding we have.) History tells us and Einstein knew he was wrong sometimes, thought he was in the case of gravitational waves, ripples, but decided, rightly as it turned out, that he was right. Doubt is a key part of progress in the same way mistakes are. Science is only as good as the people who make it and those who exploit it.

Welcome to BH. There is another factor you may need to consider here. You are definitely in the right to crack although I do worry that the new single storey permission may have had some clause closing the previous two storey one. The additional factor is how long you intend to live in the property. When you come to sell it you will have to declare any issues you have had with neighbours, in England anyway. If only a few years after build this may put off purchasers who do not want to be landing in a still raw battle zone.

Sadly from my perspective it feels like the usual closed shop approach, to do heat pumps you need to be registered with both the Plumbing and Electrical registration bodies - that is a tough ask for the sole trader and so a restriction to trade even in the trade. This is not the case for Gas boilers as I understand it. It is interesting that HMG feels we need such strong regulation in such relatively simple technologies but none in the complex ones - eg AI, IoT and Social Networks (coming I know but decades too late for many with serious well being issues because of it). I appreciate that many do not have the confidence to do it, manage it and/or evaluate options (other than in money / personality terms) for themselves and that is a failing of our education system and indeed our whole investment system.

Interesting read - not everything is well in the state of MCS - looks like more than 50% of the installs they looked at did not have the correct Legionella controls and the estimation of how good the home's insulation was seems often to have been woefully subjective rather than objective. It also seems that systems designers, those given the authority to say what was correct - and therefore what you should buy and HMG should subsidies, did not use consistent approaches so your design could have been different from two different suppliers. There seems much that is positive however.

Very true - in fact the S curve is the pattern of everything BUT (could have used AND but I cannot be bothered) the S-curve is for a single technology. What people don't get is the changeover from one to another and the nature of that changeover. Stone age people got very good at knapping flint, so good in fact that we cannot replicate how good they were with todays technology, in getting good they engineered a whole society around it. People who mined the flint, people who gathered the wood to make arrows, people who knapped the flint to make the arrow heads and cutting implements, people who took the arrows and plunged them into woolly Mammoths, people butchered the meat with flint knives, people who cooked it. Anyway when the Bronze wielding hoards came over the hills at them they needed to defend their way of life strongly as their society was built on flint! Ever since, and somewhat before for other technologies, there have been two sides in every transition from one S-curve to another. The attacker, in the present case the ASHP, and the defender - the gas boiler. Our whole way of life is being challenged here, it is not just a technology switch. In general the attacker needs first to create a crude product that enough people in a particular niche of the market (that's people like us) will like and purchase (in my view this is about where are). They can then grow into other aspects of the market as their technologies improves - but improve it must and gather around it a band of followers in vanguard of the early adopters who can persuade others of its efficacy, if it does not achieve all these things it will wither and die. Meanwhile the defender needs to make an array of mistakes to be overthrown; misreading the market, not understanding their customers, thinking they are big enough to withstand the onslaught and that they are able to react fast enough not to be displaced. If the attacker wins then they become the defender and while this whole thing is going along another S-curve starts up some place that makes both the S-curves we have been discussing redundant. Systems thinking 101! (Mostly after Foster, R N, Innovation the attackers advantage, 1986) And my first mobile phone also of 1986 cost £1500 to purchase (£4K at todays prices) - people told me it would never catch on!

That's an interesting read....

Welcome to the THE forum for people like us. Great to have you aboard.

They are an abomination that is for sure.

Still an opportunity then - does it need continuous modulation or would occasional set and forget be an option I wonder?

Market opportunity then - IoT rules....

This should be solvable with software that gathers the data and adjusts settings - not sure why this not already an option.
