    Recommendation for welding mask (up to £100)

    Unfortunately our Lidl never ever has and sort of welding gear.

    Recommendation for welding mask (up to £100)

    Turns out it's not dead. I had already ordered a battery holder before I decided it was a lost cause. So once the holder turned up I fitted it, for the sake of five minutes soldering. And it works. To start with the same sort of misbehaviour, for example darkening when looking near the...

    Recommendation for welding mask (up to £100)

    I think it's goosed. Wiring in a new battery looked hopeful at first, but it still flickered and now doesn't work at all.

    Recommendation for welding mask (up to £100)

    Thanks. Budget coukd poss8bly be stretched. Can that model take a magnifier? Looking around it seems like the helmets with larger viewing area can't.

    Recommendation for welding mask (up to £100)

    Hi, I'm looking for an auto welding mask, to replace my existing Esab "Warrior" that has now died. That cost £60 +VAT in 2014 so my thinking is that for the same sort of money i should be able to get something better ("true colour" for example). Any recommendations? It would need to have...

    grid meter

    You'd need to meter everything in both directions. You don't get billed on the net amount, even within on 1/2 slot if you export say 1kWh in the first half, and import 1kWh in the second half then these would each be billed and credited. Not cancelled out.

    grid meter

    In terms of the OPs metering arrangements, I don't see how anything else could be done automatically. That would require his meter to charge a reduced rate if the electricity consumed would otherwise have been exported. One possible compromise might be to apply a discount for days where he...

    grid meter

    Octopus offers 15p flat rate, but only if you are with them for import. I believe it's credited month by month.

    grid meter

    Just out of interest what's your export unit rate? Question to both the OP and to ericmark i guess.

    grid meter

    Depends on the relationship, agreement or contract. If everything's metered it's not free electricity as it's reduced your export payments by 5kWh.

    Losing heat through extractor

    A counter current heat exchanger can do a lot better than that. Whether domestic appliances are that sophisticated is another question.

    How do I wire 2-way light switches, please? (Ed. )

    The old wiring in our garage/workshop used twin with no earth, plus various single core sheathed cables to provide enough cores. Earthing for the metal switches was provided by a fly lead from the adjacent power point. Where I retained two way switching I replaced the drop cables with three...

    How do I wire 2-way light switches, please? (Ed. )

    That's exactly what I meant. And regarding terminal blocks for N, grabbed from another site. And I think if feed and light were connected to the same switch, you'd still need one block to connect N ..

    How do I wire 2-way light switches, please? (Ed. )

    Don't they both need at least one connector block for Neutral? I've seen a third method when the supply comes to the light fitting, with 3 core + earth down to each switch.

    Evaluate my smart meter installs

    My reason was to get on a "smart" tariff, currently saving me around 30% compared to standard variable. That might be less of a benefit when (if) we get the solar panels, but then we'd need the smart meter anyway to get export payments. Nobody's doing deemed export for new installs, and the...

    I take it you're not a smart meter fan. Out of interest, why not?

    Duct For Control/Data Cables on my Own Land

    Hi, I need to run a duct from our garage, under the (gravel) drive to the house. Specifically this is for a monitoring sensor needed for our planned solar install, but while doing this I'll also run two or maybe three Ethernet Cat5e cables. So nothing above 48V. Are there any regulatory...

    Camper van electrics

    Unless it's a real fancy battery it will have a really short life if discharged below 50%. And without an equally fancy charger probably won't ever be fully charged. So usable capacity may be more like 30Ah.
