I did move to Octopus with their EV tariff, very little difference in cost of off-peak and peak to British Gas, 8.50p and 30.51p, 68.34p/day standing charge, but now get paid for export 15p/kWh. As a result, end of April to date, net cost around zero. I will be paying any day now, the battery...

A MCB is two devices in one, the thermal trip will take time to work, and the magnet part is B (3 to 5 times thermal) C (5 - 10 times thermal) and D (10 - 20 times thermal) the magnetic part is required, so the supply will open within the required time, should there be a direct short, so with a...

Waterproof IP68 is costly, in the main we go water resistance, which could be simply a plastic box over the plug and socket, done that to charge car when one extension lead not long enough, was only connected overnight, plug and socket on a brick, so surface water could not reach it, and the...

A LED is a current dependent device, so it needs a driver to convert them into being a voltage dependent device. A white LED is around 3 volts, and a red one around 1.2 volts, so if running from say 12 volts, one can use a resistor to convert to voltage from current and have 3 LED's and a...

Remote now working Sky and TV, so that bit sorted. The satellite slowly removing the encrypted and god and sex channels, so becoming useable. But never really thought that changing a TV set would involve so much, was the extra few inches worth it? I was finding it hard to read the guide on the...

Yes, but need some time while wife is not watching TV to try and set things up. With info already given.

Sorry, box was not to hand, I looked for details on the instructions, and they were not shown. I am slowly masking all the useless channels on free to air, but as yet failed to get Blu-ray player to work. And the Sky remote is not controlling volume, and can't remember how it is done. I am sure...

Confused, looked at the manual and it says it has 3 amp contacts so it will not take to load to storage radiators. Unless it only powers a fan, and then a thermostat would still work. Seems I have missed something. So basics, something turns heaters on overnight for 7 hours. Power goes into...

I have not used a programmer in years, when the tungsten light bulb went, I found wanted the heating higher in the evening than through the day, as no inferred from the bulbs any more. So I moved to programmable wall thermostats and TRV heads, as each room independently controlled, the standard...

Old TV 42" new TV 55" both cheap Black Friday deals, new one Sharp Aquos, three HDMI leads, satellite lead, terrestrial aerial lead, and connects to Wi-Fi and Bluetooth. It says mini AV, I assume I need some special cable? I have a composite video/audio cable to SCART, but not what looks like a...

I have two instant electric showers on a 60 amp supply. DNO fuse has not blown while I have been in the house (5 years) and I note the inverter takes some of the load now, most times they are used. I don't think this is ideal, and in parent's house will had a power shower, which got around the...

@plugwash has said what I also consider the problem with an EICR, each edition of BS7671 has two things, one is new rules, and two is clarification of old rules. New rules can state if this then that, like 2008 with bathrooms, so if you fit an RCD you don't need to bond, or they can take account...

I do wonder if the SUNVIC motorised valve actually fitted? I was at first thinking the same, until I realised this is a unique valve type, These diagrams show how these valves work, it is motored off and well as on. I have never seen one of these in the flesh so to speak, seems a good idea...

I am the same, I blame dyslexic problems, I know what I want to say, but it does not read the way I intended. That's the whole thing with a forum, someone proofreads what one has said. Seems I made an error also, it is 8 volt AC. Thanks to @opps for finding the instruction set.

I did my central heating in the summer, so loads of time to correct any problems, be it a larger connection block, or tools, in your case likely a junction box next to the boiler so only a single core into each connector in the boiler. I had the same thermostat end, they call the junction box...
