Won't be as unsightly as an PV and ST set at an angle on your flat room. The noise issue is just not there on modern ones. Planning should not refuse it if follow the MCS installation guidance, the government has set a target to install 600,000 of them a year. I would have thought that you could get a tip top system for a couple of thousand. Just hunt around on eBay to see what the component parts cost. They do take annual maintenance

And little work was done. People often forget that supply and demand is governed by demand. Now while a few people will pay over the odds to get something finished, most won't. If this was not so, we would all be infinitely cash rich with unlimited wealth.

I think you would have a highly compromised PV system. You may be better off, and this may sound odd, with a ST because when the sun does hit it, they can deliver a lot of power. So may well contribute to water heating more. An ST system can be fixed at an optimal angle and will be smaller overall. Though a simple ASHP dedicated to DHW may be more cost effective overall.

Did I not say that if material prices go up, labour prices will drop. All comes down to the money supply. If people only have 100 quid to spend, no good hoping they will pay 110.

The alternative is worse: no development. While I agree that building poor quality is unnecessary, housing people is more important than reducing new housing energy losses. Let the power generation companies clean up that sector and then the problem goes away. No point diverting resources to where it is ultimately not needed. Or just ban combustion technologies. Problem sorted.

Just trying to right a social injustice. Have to declare it every time I go for a teaching job. Can make up any story as no one actually checks it out, as long as it does not involve children and genitalia, no one cares much.

Or The Eagles's Last Resort. Interesting but in bold. She came from Providence One in Rhode Island Where the old world shadows hang heavy in the air She packed her hopes and dreams like a refugee Just as her father came across the sea She heard about a place people were smiling Spoke about the red man's ways How they loved the land They came from everywhere to the great divide Seeking a place to stand or a place to hide Down in the crowded bars out for a good time Can't wait to tell you all what it's like up there They called it paradise I don't know why Somebody laid the mountains low while the town got high Then the chilly winds blew down across the desert Through the canyons of the coast to the Malibu Where the pretty people play hungry for power To light their neon way give them things to do Some rich man came and raped the land nobody caught 'em Put up a bunch of ugly boxes Jesus people bought 'em They called it paradise the place to be They watched the hazy sun sinking in the sea We can leave it all behind sail to Lahaina Just like the missionaries did so many years ago They even brought a neon sign that said Jesus is coming Brought the white man's burden down Brought the white man's reign Who will provide the grand design what is yours and what is mine? Cause there is no more new frontier we have got to make it here Satisfy our endless needs and justify our bloody deeds In the name of destiny and in the name of God (Aaah...) And you can see them there on Sunday morning (Aaah...) Stand up and sing about what it's like up there (Aaah...) They called it paradise I don't know why (Aaah...) Call some place paradise kiss it goodbye... Ah-ah-ah... ah-ah-ah... Ooh... hoo... Ooh... hoo... Ooh... Ooh... Ah-ha... ooh... Ah... ha...

CPS as in closed panel system, is not the same as CPS, that bound me over to keep the peace for 12 months. But no fine, so pretty cheap in comparison.

There are shading issues to consider. Tracking systems are usually used in fields where the modules are spaced apart, so when the sun is below peak altitude, one module does not cast a shadow on another. Shading is the killer for PV performance. You could consider putting a fall on the roof, say 15⁰, this is to let rain flow away and take the buildup of dirt with it. But you still have to be wary of shadows caused by the roof ridge, and nearby buildings. This may be a case where individual module inverters work well. A sketch would help.

Mass and wind loading are the two things that I can think of, this would mean you need a reinforced roof. A sketch of the roof would help.

Are you thinking of laying the modules flat? This may impair their performance.

This is the whole point I am making. It is easy to heat anything up, just pump energy into it. Don't matter where the energy comes from, or what form, the definition of energy does not change. What gets difficult is doing that is a manner that meets all the 'comfort' levels. There is not an SI unit for comfort.

That is purely a case of having a powerful heating system. This is about careful and sensible design from the start. And before you know it, people will tell you all they know about 'thermal mass'.

Right. So like SIPs but without the structural element.

Tried to Google this with no luck. Do you me CLT, cross laminated timber? As for the prices, if that is important, don't self build.

If a company says you can have a 20% discount (the VAT), I automatically assume that the price has already gone up and they are still going to spend all my money.

Can glass fibres (what we used to call choppings) be put into the mix to help reduce shrinkage and the associated cracking.

Not a term used these days, which is a shame as it was very clear what it meant (even if some ply that was stamped with it did not comply). "WBP stands for “Water Boiled Proof”. This is an old British Standard term although people still refer to it. The new terms are EN 636-(1, 2, 3) and EN 314-2 (Class 1, 2, 3),"

You can report that to Trading Standards. Not allowed to be sold unless it is over a fixed amount (can't remember what that is 2 tonne?). But the whole environmental thing is a lot more than just the moisture content.

Surely that depends where you stop measuring the costs. If you take environmental costs (and people that burn timber never do) into account, you may find that there is a lot less value.

No, I the sun is out and my customers have been well fed, for now. I just find it strange that the tolerances on building components is so appallingly bad, it would not be acceptable anywhere else (in catering, we generally buy by mass, not mass plus of minus 250g). The ignorance of new technique is also staggering. Guy who fitted my neighbours new windows did not understand the concept of airtighness, or MVHR. Very few of us on here can agree on the best heating system for a house, and people still talk about woodburners, a 2 million year old technology. Customers have to insist on getting what they want, then the industry needs to step up and supply it.

You may struggle with that. If you cannot get water into the system fast enough, there is no way it can come out fast enough. Try calculating at 10 litre per minute for each shower. One way may be to use two cylinders, of a vented and pumped system. You may be able to use plate heat exchangers as well, they can have a reasonable flow rate and power rating.

It does deliver around 200,000 houses a year. That is really a totally different thing, and is down to legislation, standards and enforcement.

If Durosol made cars or boats, life would be so much better won't it. 15mm gaps FFS, what is that about.

Did I not say earlier that the building industry was total crap. No wonder we can't get houses built at a reasonable price.
