This bit, from the same page, was interesting. https://www.theguardian.com/artanddesign/article/2024/jun/04/plumbed-bath-diy-diehards-affordable-homes

My system is vented, and I have a shower pump. Worth having one but there has to be a way to make them quiet, so no plonking them under the bath, the noise though the floor is too much.

Yes it is. I lectured for a few years, some things student do is quite tame, other things opened my eyes quite a bit. One thing they do, well did pre COVID/Brexit is travel a lot more.

Any chance it is condensation?

Go and take a bit for testing. My place is a 1987 build. Thermally quite good, and still with the original timber windows, though I have made up some secondary glazing that makes it triple glazed.

Couple of things. I had a flat when I was at college (the first time). Wish it had been a top floor one, noise from above, below sides and stairs was horrible. What is the rest of the building like thermally? I use 'old fashioned' E7 heating and hot water. Really not that bad price wise to run in my small house, and it is very reliable, and quiet. But then I am in a much sunnier and warmer place.

As a rule, PV slates are expensive and of lower efficiency than normal modules. They are a pain to wire up as well. Unless it is the only way (planning constraints), best avoided.

@RenovateHouse May be worth getting a cheap Lidl laser level, then you can play in the dark and see how far out things are.

Only going to be a temporary ban on the ban. Just political shuffling really.

Not really. The chemical formula may similar, but the processing is different i.e. limestone is compressed in a high CO2 atmosphere for at least 500 million years (Precambrian era. So not mixed up by a builder. The Egyptians used clays and gypsum before the Romans were using lime mixes. They pyramids are still there, and there is a lot of evidence to suggest that they are not carved stone, but castings. That is more to do with local geography than material properties though.

Buy the cheapest ones you like the look of. Even the soft delabole slates down here last a few hundred years. But have a look at the integrated PV, it may work out cheaper than slating.

Pictures like that, which was probably staged anyway (the plane flying though the hanger was) never used to bother me, until I took up rock climbing. Now they give me the willies.

I think the problem was that when Andrew (used to contribute to this forums predecessor) got a marketing company involved, proper development stopped. It never really moved from a preproduction to production.

Just teasing a bit here. https://scitechdaily.com/eco-friendly-fibers-may-pose-a-greater-threat-to-the-planet-than-plastics-concerning-study-reveals/

Are you sure? There is a lot of info about SAs on here.

So he lets the generator run in a shed/garage without proper exhaust extraction. What a twat.

Won't the pipe expand and contract during the heating season, so short of something quite flexible, not much will stay stuck to it.

Only if it not 40 years ago.

Do they have milk and alcohol? Only Dr I ever needed

I think the OP @Selina has run away.

The comments are interesting.

It is a bit, but it comes down to the Ideal Gas Law and Fluid density changes. Actually it is entropy, the state of disorder. A liquid has lower entropy than a gas: it is more ordered. All that means is that when a fluid is in the gaseous state, it is easier (takes less energy) to increase the temperate, mainly because the colder molecules, or atom in an ideal gas, are slower moving, so easier for the photons (which are the particle that transfer the energy) to hit (raise the energy level of some of the electrons). (that is a crude 'mechanical' model, but easier to understand than the quantum model, well the sums are easier)

There is a point, and it varies with other material properties, where increasing the outside area because of thicker insulation, actually increases the losses. Might just be for pipes though, corners make thermal modelling tricky, why I use the simplified method of adding the wall thickness area to the exposed area. Makes sense to me. So take a simple wall that is 5 metres wide, 5 metres high and 0.25 metres thick, normally the exposed area would be 25 m2, but because of 'edges and corners' it is actually 30 m2. It over estimates the losses, on thicker walls, but that is the better way than underestimating. Shared edges/corners can have a reduction, so half wall thickness.

4 quid gets you a sign for the path.
