    Don't get me started on which vs. that.

    Colon is correct, because the second part is as a result of the first. You'd use a semi if you had two sentences to join together, but style guides increasingly suggest eliminating semicolons wherever possible. Some style guides have it that you'd capitalise the W if the phrase after the colon was a complete sentence, which it is. But there's no hard-and-fast rule.

    I'm far from an expert practitioner, but I still don't see the problem. As I see it, your mitigating factors are: A metal conduit in screed isn't going to insulate a warming cable, so a 37 A rating at 30 degrees will be conservative, no? 7 kW is less than 30 A at 240 V, assuming a resistive load The 7 kW spec is probably conservative anyway The 37 A rating will be continuous, and even at Christmas you won't draw 30 A for very long (induction hobs modulate by switching the load off and on fairly fast) @Ferdinand's suggestion of a breaker at the hob end seems like good belt 'n' braces if you're worried (32 A?) I am not an electrician, this is not advice. See also this remarkably similar discussion: https://www.electriciansforums.co.uk/threads/28a-in-4mm-cable-6-5kw-hob.122707/

    What is the conduit buried in?

    Isn't a 4mm cable rated at 37A, if ungrouped? That's more than 8kW, surely?

    For conventional construction, it's a good idea to keep it warm enough to keep away dampness. Wet materials have a poorer U value, hence the "paradox" of needing less energy to heat a house for 24 hours with timed thermostats (vs. a conventional controller switching the system off overnight and during the day).

    Cloudflare's main business is protecting websites from denial-of-service attacks, by proxying traffic for them. CF sells the service with a freemium model, so there are countless "undesirable" sites protected by CF that lazy journalists can point to with shock-horror opprobrium. One well-known example is The Pirate Bay.

    Sadly, using network 1/8 is challenging. Many years ago, after the demise of the BBN packet-radio network, it was marked as "reserved," but countless networking people decided that word meant they could use it as a private, unroutable network address (despite there being several ranges such as 10/8 and 192.168/16 set aside for this). Cloudflare is doing its best to fix the problem, but it's a bit like the Augean stables. As an alternative, look into 9.9.9.9, which focusses on threats and has a similar censorship and privacy stance. It's also not controlled by a single commercial entity, being a not-for-profit JV of IBM, PCH and GCA, in collaboration with several others (wonderful as Cloudflare is today, who knows what they'll be in a year or two's time). From the About page:

    I took a passing interest in the furniture at B&M when I was in there last (@Coopers is a big fan of American Payday bars, and I don't know anyone else in this country that stocks them). This is far from an in-depth review, but I very much doubt any of it would "withstand a few seasons of holiday letting."

    Yeah, my point was to plumb it so it opened when not energised. But I missed the point about being temperature sensitive, so dumping even if there's power. But could you do what I suggested but add a thermost that cuts the power if overtemp? It would mean your dump rad would always warm up if there was a power cut, but that could be no bad thing, I guess.
  13. richi
    I'd naïvely assume you can use a normal 2-way motorised valve, capping off the outlet that gets opened when it's energised. Do I win the banana or the wooden spoon?

    How about one of those floor sockets with a sprung, hinged flap?

    Looking at this again, there's this thing called a QuickCharge Aware cable in the newer versions of the standard. Looks like a revolting hack to me. I guess that's what this is. Bloody standards people. USB-C was supposed to make everything simple again, but here we are with another camel.
  16. richi
    That page seems to imply that an A-to-C cable can support UPD, but it's a physical impossibility, because A doesn't have the CC pin. Marketing people are dim. It does imply it's rated for 15W (3A at 5V), so you can at least manage QC2, and perhaps QC3. But you won't be able to, say, charge your laptop at 100W (5A at 20V).
  17. richi
    That's only true for some applications. USB-C is a new, 24-pin standard. USB-A is the old, 4-pin standard. For example, an A-to-C cable won't support the USB Power Delivery standard, so the best you can hope for is 2A, or perhaps QC.

    In this pic, some of the white protective film is still on the window frames. The slates are Eternit Thrutone fibre cement. This is a garage conversion and extension. You can just see the rest of the house through the bifolds (the older part is phase II, which we're still planning).

    All came from a local company, Roofline Solutions, who also supplied RAL-matched guttering.

    BBC R4 PM reporting the "cladding" rainscreen panels used -- Reynobond PE -- were certified below the minimum 'B' fire rating required by the ADs. Some of the panels -- the riveted config -- scored C, and others -- the cassette system -- scored E. http://www.bbc.co.uk/news/uk-43558186

    I wonder how hygienic an over-sized vessel is

    Personally, I estimate our daily usage varies by around ±50% -- not including external taps, which I'd plumb from the pre-softener feed. (And anyway, this is BuildHub; we're obligated to have problems of perspective!)

    I'm far from the expert. In fact, most of what I learned came from @JSHarris. But a simpler, timed softeners regenerate overnight, whether it needs to or not. Whereas a metered softener will skip regeneration if not enough water's been used. (The regeneration process is mumble-something-to-do-with-ions-mumble-resin-squirrel.) Ergo, timed softeners can waste salt, water and electricity. I suspect overuse of salt might also cause excess sodium in the water at the taps, but don't quote me on that.
  24. richi
    Looks like the BWT/Screwfix one is metered, so probably a much better idea.

    Best way to get someone's attention (other than the 1st-level CSC team) is posting at https://community.plus.net/t5/Fibre-Broadband/bd-p/Fibre If your post doesn't get any substantive attention from a Plusnet expert, mention a superuser, such as Townman and ask for an escalation.
