    If anybody's interested, the government have published a new document "domestic hot-water use"

    https://assets.publishing.service.gov.uk/media/65f43b919d99de001d03df8a/domestic-hot-water-use-insights.pdf

    They seem to have collected a bunch of data from people who have "intelligent" boilers and maybe other things. Some interesting and some scary data.

    Also see

    higher water pressure seems to result in shorter showers and less water use overall.

    (Not in this data but I wonder how much this makes flow rate restriction ineffective)

    "Also see

    I would if I could but the site just says "For full functionality of this site it is necessary to enable JavaScript. Here are instructions for enabling JavaScript in your web browser." Even after I enable JS and turn off my addons. Current FF ESR.

    It worked on my chromebook..interesting it said people want to get a particular experience in the shower.
    Two things which I think havent helped with water use are combi boilers,so there is no tank to drain thus you can have a shower indefinetly.
    The other one is single lever mixer taps.

    Nope. Doesn't work in chromium either.

    Does that page contain the actual content or can you download a PDF or whatever?

    Is there an email address I can complain to? edit: I found support@osf.io in the source of the page, so I've complained there.

    I find the first sentence staggering.

    'England is projected to face a water supply shortfall of 4 billion litres daily by
    2050, mostly due to population growth and increasing climate-driven
    droughts and flooding.'

    To put it in perspective, the largest reservoir in the SW has a total capacity of 36 billion litres.

    I got a response to my complaint, along the lines of "works for me" but with no indication of what browser etc they were using. :( But the site works this morning, so I suppose they had a problem with their CDN or somesuch. It seems to be a puff-piece for the "smart timers" they used. There are some links at the bottom to further information, I see.

    There's a government article at https://www.gov.uk/government/publications/a-review-of-englands-draft-regional-and-water-resources-management-plans/a-summary-of-englands-draft-regional-and-water-resources-management-plans that is worth reading.

    Sorry djh but I am hijacking this thread as the site won't let me start a new one and at least this is about hot water so...

    I have a gap down the back of my hot water tank that I would like to insulate to further improve the retention of heat. It is too narrow and uneven to push rockwool insulation down so I though I could pour insulation beads down it to fill the void. Just wondering if there would be any reason not to do this and also if I go ahead, what would be the best product to use?

    Thanks for any advice.

    We did this. Our 200l solar tank is in a built in square cupboard, with maybe 200mm gap between the round tank and the cupboard walls. I fitted some bits of XPS I had around the tank, nice and snug to the wall, used a bit of expanding foam to make it secure. Then poured eps beads in the void - they were from eBay, intended for a bean bag. I’d already tried leaving them in boiling water-nothing happened, so I figure they were fine even though our tank did sometimes get extremely hot as it had solar thermal back then. I foam fitted an XPS lid on top, so the beans don’t blow about.
    This was all 10 years ago - haven’t had any trouble with it. Of course we have no electrics in the bit I’ve insulated.
    Added bonus is that socks drying over the tank don’t fall down the back now :-)
