Or enough heat to heat my whole house, squashed into one small room.

What is the ceiling heights of the raised and dropped areas?

Sounds like a catch all to cover conventional flue boilers? Or is it to allow convection for cooling?

Not convinced by that. at 230V and 2500Kohms the leakage is 1mA, that won't trip an rcd. I would power it up temporarily without an rcd, run it for a few minutes and then repeat the IR tests as soon as you can after turning it off.

At least you have a diagnosis, even if it is not the one you want. I take it it's out of warranty? What sort of readings did he get?

Someone's maths is a bit suspect. If they estimate you will save £304 per year, then after 25 years, that would be £7,600 saved. They are saying £19,456 so they must be calculating a BIG increase in electricity prices, but giving you no figures to scrutinise what assumptions they may have made. Also, if you are saving 1941kg CO2 per year, after 25 years that would be 48,525 so why are they saying only 37,850? Are they factoring in a drop in performance over that time?

You can do EXACTLY the same for the environment by doing as I did and spending as little as possible (£1500 in my case) to DIY install a 4kWp solar PV system. I might add battery storage at some point when that too becomes cheap enough to DIY install.

That's a new slant on project fear that I have not heard before.

I will let someone else do a spreadsheet. But it will shorten the payback time obviously. At the end of my example 29 years, your electricity price would have nearly doubled. To counter that argument, if you had instead put your £12,920 into the best savings account you could what would that have compounded up to?

SW did give us a quote okay, And when pushed for an "all works" quote, turned out to be the cheapest way to get a road crossing done.

I was working in a house where they did the opposite. Dropped section in the middle with LED lights around it, leaving the perimeter at the original 2400 height, and it did not feel as though the ceiling was too low.

Assume you will generate 3200 kWh per year, and because you have batteries you will use it all (ignoring losses in charge / discharge) and your electricity costs 14.8p per kWh. Then you will save £473 per year off your electricity bill. So to just repay the £12920 install cost will take you 29.6 years. It will be worse than that, as there are scaffold costs to be added to that quote. In that time you will probably have to replace the inverter at least once, and I doubt the batteries will last the 29 years. So you will be throwing money at it to repair / maintain it, even before it has repaid it's cost. There is no longer any FIT payments and you won't be exporting anything so the export payment scheme is irrelevant. Sorry to rain on your parade, but it makes no sense to pay anything like that much imho.

No such problems with our wet room. Perhaps the "non slip" porcelain tiles could be a bit less slippy? But we are aware of them so use them within their limits. The whole point of it being a wet room is that it does not matter where the water goes. If you have a bit where a pubble forms or it runs away from the shower, it has been done wrong.

And didn't a Grand Designs house use it for just about everything, inside and out?

Why is it not enough? I know you are somewhat taller than me, but what finished headroom do you want to achieve? I have seen similar arangements achieved with a 100mm drop so you would have a ceiling height of the lower bit of about 2300mm.

It's looking like gmail is the one she prefers, so I might simply set up forwarding at the source to forward her proper email to the gmail account.

In something like 30+ years of using computers I have only ever had an AV program find ONE threat, and that was in an email that I would never have opened anyway because it looked so suspicious.

So would the gmail app also have done the "proper" email?

I guess so? it's just called "mail" and is the default application for that loaded. Anyway all sorted now, proper email on "mail" and gmail using the gmail app.

Don't forget to cover you hinges in masking tape to keep all the sealant, goo or whatever off them.

As @Jeremy Harris pointed out, if you do walls first with multipanel, and then tile the floor you risk the detail of water running down the wall and sitting in a channel and soaking into the wooden backing of the multipanel unless you seal it absolutely perfectly. A LOT easier to floor first, fit the multipanel onto the floor with a very small gap sealed with CT1 etc.

we have a squegee on a long pole so we can dry the floor without bending.

gmail app sounds better to keep them separate.

One more question, to save me endless grief and frustration. This has set up her email based on the house name domain name. She also has a @gmail account How can I add that also to the ipad email app?

Thank you. As I said, I am a dumb user used to "normal" computers like windows, linux etc. I was looking for settings relating to an email program. I expected to find the settings somewhere within the email program like on every other platform. I didn't expect them to be hidden away in some centralised settings application. It was as I suspected a fat finger / tiny keyboard typo. All working now.
