Fitting an “oversize” hot water cylinder won’t make 45-50 degrees of heat pump flow temperature hotter.

To answer in the most simplest way, 3 phase means you get more power, at a lower current and therefore less conductor material required (smaller cables) and so costs are lower. There are technical reasons why 3 phase has advantages over single phase, but for the purpose of discussing EV charging...

If I recall, it means the connector is designed for 0.08-2.5mm2 solid core cable and up to 4mm2 flexible stranded cable.

No, they allege it sits under the tiles but above the membrane or bitch felt and so vents out through the gap between the tiles, membrane and wooden slats (a few piccies attached from the website)

Do these do what they say on the tin? Or snake oil? https://lapventsales.co.uk/product/exhaust-lapvent/

Welcome to the world of arty farty modern light fittings which the designers chose form over function. This is how they all are and yes - they expect you to put all of the other wiring into a terminal block and shove it up into the ceiling void above the fitting.

it’s quite simple, you push the earth sheathing out of the way and grip the CPC and push it in. Once done the earth sheathing will spring back into place. If you can’t, then the sheathing is too long.

Resurrecting an old thread but thought it worth mentioning that I’ve now installed a “backup box” to our solar and battery system which is basically a changeover contactor box that allows off grid usage and disconnects from your the grid. My inverter is capable of supplying 5kw in “off grid”...

The fibreglass isn’t particularly old, at least - the top layer isn’t which is the one I’ve moved out the way. The top layer was done in 2011 by my mother! Must admit, fibreglass doesn’t scare me like asbestos does. Got a mask and disposable suit coming tomorrow so I can get this suspect...

Might be cos of the amount of zoom I used lol. Asbestos scares me to **** to I ain’t getting closer just in case. I’ll try get a better image.

If you click on it, it does open up into a decent res image.

To you experienced builders does this look like asbestos sheet to you? Unearthed after moving some fibreglass insulation out of the way. Wondering why it would have been used in this way if it is asbestos.

On most modern economy 7 installations, with digital or smart meters - as you say, there is no “switching” done. The rate change is done on the meter based on the time and it will display the 2 rates separately. There is no longer a need to fit separate off peak circuits. Your entire dwelling...

No.

The confusion I’m referring to is people saying the top RH item is a wireless receiver for Hive.
