    Learning about myself :-)

    I remember a homemade washing machine where the drum did not turn. We used the ships lathe, with a starting handle in it, and half an oil drum at the end, with soapy water in it, and we tied the overalls to the starting handle and set the lathe slowly turning, dunking them in the soapy water...

    Aqara Radiator Thermostat W600 Review – Quiet, Accurate Smart Heating what about the rest?

    I did not restart this, I got an alert. I do remember with parents home, the central heating was not used as the sole source of heating, and my dad would switch it on/off manually. And there is northing wrong with this approach, it does not need automating. We had fires like this for years...

    What is electrical equipment and what is an electrical installation?

    Yes, some odd names have been invented, so we can have an overload device which does not create a circuit as can't really have a final final circuit. I see your point, portacabins, caravans, and narrow boats all can be plugged in, main point is TN-C-S is not allowed, but within the caravan or...

    Oh dear, must change that. I remember looking to get more info on the family tree, and it directed me to a copy of my own website.

    Aqara Radiator Thermostat W600 Review – Quiet, Accurate Smart Heating what about the rest?

    Not sure why I have just received thanks for this. I have just started a thread saying how it is now outdated. There are two ways to control central heating, and a lot more items, up/down or on/off, in some cases we turn it on/off that rapid it works similar to up/down, other times the mixing of...

    Portable air conditioning units.

    Fans slowly loose they advantage as the temperature climbs to 36°C and make the situation worse after that point. So today living room at 24°C with the AC running, and from the amount of condensate I have poured down the drain, also a lot drier. The flat is built into the side of the hill we...

    Happy Brexit Anniversary??

    Rest in peace Terry Pratchett. Well in spite of all that extra money we were told was going to the NHS we still here they want more. Some things have gone up in price, I noted the eQ-3 TRV heads which I got for £15 each now doubled in price, but others have dropped in price, and the others...

    Replace analog timer?

    Today very different, AC been on most of the day, I looked at use, and 3432 watts, tried to work out what, 755 watts for the AC, but due to AC, DHW heating came on late, it uses excess solar, so started to heat it at 11:26, and just finished at 12:12 but a 3 kW, that's just 2.3 kWh and likely...

    What is electrical equipment and what is an electrical installation?

    How can it be a fixture and not a fixture at the same time?

    Replace analog timer?

    A long way from me, I am afraid. 11 hours return according to Google. There is only any point in a timer if you are on a split tariff, as water holds the heat for a long time even three days after turning the immersion off, there is still warm water. The immersion uses so little not worth...

    Will bonding cause an MCB to operate?

    Yes, but the hot leg method normally has a centre tap on one winding, the TBM in Hong Kong did not have that, it was an IT system. I have also seen some strange earthing methods with a Honda generator, where to earth we had 57.5 - 0 - 172.5 volts. It was due to trying to make the generator...

    horny cable or SWA ?

    Have you got an option, I assume moving means re-gassing etc, so likely you have no say in the matter.

    Interest only, at what point is it better to use electric water heating over gas and oil?

    In the main, looking for if worth having a local DHW supply in the kitchen. To wash hands, likely electric is the best option, and to run a bath possibly oil may have the edge, but cost of electric is not easy to work out, as I am working with three prices, 8.625p/kWh off-peak, 12p/kWh loss of...

    Will bonding cause an MCB to operate?

    I don't know the earth requirements for a DNO supply. I know it took between 3 and 8 x 1.2 meter earth rods to get an 8 Ω reading in Point of Ayr gas terminal so for most homes we are likely looking at around 60 Ω but even with a 0.5 Ω earth mat, to work out current one would have to add the...

    Steps, cement or not, and what to put under them.

    Think I will leave it for a time, the steps are finished, the handrails in place, and patio is down, will need to relay steps once settled, but all useable as it is.

    Will bonding cause an MCB to operate?

    Bonding is so multi faults will not cause two exposed metallic objects from have a voltage between them. If the supply on feeds one item for example a shaver then it would be safer not to have bonding. But most transformers supply many things, so we use bonding to cause auto disconnection in the...

    Replace analog timer?

    I had the same, swapped it for Nest at ½ hour per day seemed too much, at ½ hour 4 days of the week warm water not hot, the boiler is 20 kW so at ½ hour per day it only actually runs for 20 minutes, as return water too hot, so that's 186 kWh per lunar month. My solar diverter (iboost+) measured...

    Replace analog timer?

    So easy bit first, L to L and N to N. L1 to 4 L3 to 3 But then it gets a bit harder, the existing timer has the option to change what it does. They were sold as 10/16 programmable controllers, and they counted off as an option, but the internal switches changed it from 10 to 16, and it depended...

    Combi with hot water tank - no HW

    Motorised valves have micro switches, which do fail, idea is valve opens before it fires the boiler, but in the main they stick on rather than off. As to what valve is fitted, is anyone's guess, I have motorised valves on my C Plan system, and with electronic TRV heads they are not really...
