    @Ferdinand interesting, thanks. I use Zeek and get similar or better discounts (e.g., I just bought £150 of M&S vouchers at 15% off). This link gives you an extra £5 discount code [and it kicks back to me as well, so mods please delete if it makes you feel uncomfortable].

    According to Mark Coles, Technical Regulations Manager at IET, fires can be caused because the installers need to "jiggle the wires around to make the connection."

    Just heard on Radio 4 You And Yours that tonight's Watchdog will "investigate" how smart meter installs are causing house fires. I dare say it'll be an intelligent, insightful, in-depth report. And not at all irritatingly specious.

    Thinsulex? Is this the stuff that @JSHarris is (ahem) no fan of? If all you care about is blocking radiant heat, then why not just line your roof with aluminium foil? But it can't possibly keep the heat in your house and stop it from travelling through the fabric.

    But think also about whether you need a heat pump at all. If your key criterion is cost, you could save the vast proportion of the capital cost by doubling or tripling the running cost. If your house needs a very low heat input, why invest in a heat pump? Do the maths.

    cf the memory address decoder chip in the BBC Micro. Acorn tried several "pin-for-pin" replacement chips, but none of them worked. The scary thing is, they concluded they were using the original out of spec, but they never discovered in what way. A subtle manufacturing change to the original part could at any time have made Acorn's sales pipeline grind to a halt.

    This is certainly true with ARM. To hear Steve Furber tell the story, ARM wasn't designed to be very low power, nor mobile. But it was its extreme power efficiency is what put it in so many mobile devices. edit to clarify: the original design objective was less than 1 Watt, but the first test device drew about 10% of that.

    I had an original Mk.1 Acorn Atom, full-loaded with a heady 12 KB of static RAM and the optional floating-point ROM. Phear me. All the chips were in sockets, mounted to the underside of the PCB. Unfortunately, the keyboard was mounted on the top, so typing gradually made the chips fall out. Every week, it would need preventative maintenance (i.e., open the case and push all the chips back in).

    Acorn's biggest problem was the ridiculously huge bet it made on the Electron—a crippled BBC Micro that was also badly delayed, leaving the company with piles of unsold stock too late for Christmas. The ARMv1 architecture first saw the light of day in the Archimedes line, which was the follow-on BBC product. It also had an ARM second CPU board for the BBC around that time, IIRC. Archimedes saw some success worldwide as a real-time on-screen graphics generator for TV (it was used for the National Lottery, for instance).

    OTOH, Sinclair Radionics Ltd. was given NEB public money, but Clive got so fed up with the interference, he trousered the grant, set up a new company—Sinclair Research Ltd., née Science of Cambridge, née Sinclair Instrument, née Ablesdeal—allowing Radionics to whither on the vine, and the government to see no direct return on the investment.

    Thanks, but neither do a plain white-primed version. Todd's oak veneer set looks nice though (but la @Coopers specified white).

    Thanks, but their product is by XL also.

    Thanks. Looks like the only suitable set on that site is from XL ;-)

    We ordered a rebated double-door set from XL Joinery, via Jewson. This is a pair of Pattern 10 glazed, white-primed, solid wood, internal doors. £300 inc. VAT, delivered. 1981 x 1168 mm, pictures at this link. The first set was the wrong size (Jewson's fault). The second had a 6mm gap in the centre of the rebate. The third arrived damaged at Jewson, so they sent them straight back. The fourth is hilariously badly warped. I'd have given up by now, but XL is so incompetent that it sent two replacements to Jewson, so we await the fifth pair... But assuming #5 is also wrong, does anyone have a recommendation for another door manufacturer that knows what the £@!# it's doing?

    Surely part of the problem is that there is no nonce? I'll get my coat…

    We have RAL7016 slates, soffits/facias, and windows. We got Swish Deepflow guttering also in 7016 (bought from Roofline Solutions).

    From one content-marketing spod to another, welcome @SunampBlogger! As if it needed saying, tread carefully ;-)

    Agreed. We got two of these for our new south-west-facing Veluxen: roofwindows.co.uk/blinds/by-type/solstro-sunscreen-awning-blinds-for-velux-roof-windows So far, they seem to work well.

    Best of luck. We're rooting for you...

    What's your alternative?

    Are you sure? Or did you get infinity or 9.999, either of which would indicate an open-circuit. A reading of a few Ohms would say the element is working fine. A reading of zero would say there's a short (unless your meter is set to a high range).

    Similar to the Aquabion, whose website makes much of some independent test results, hidden behind a registration wall. But when one gives up some dummy personal details, it redirects to another site... which doesn't exist.

    "Each Halcyan Water Conditioner patented alloy core is designed and configured with specially foundry blended metals scientifically selected from both the Cathode and Anode end of the Galvanic Scale. Sized correctly, the patented catalytic alloy core changes the crystalline structure of the minerals in water..." https://halcyanwater.com/domestic/wp-content/uploads/2016/03/HalcyanTechnicalOverviewDomesticincFAQs.pdf Forgive my scepticism, but coughbullsh!tcough. Oh, and the smaller whole-house unit is £760...
