If there really are no other vents, then you already have a problem - that of the gas fire billowing toxic combustion products into the room. Open flue gas appliances require substantial ventilation to allow air in to the room.

Load profiles, and the fact that the majority of homes do not currently have an EV. Just as their export / solar / battery / heatpump and other tariffs are all limited to those who have such devices, and therefore will be a small percentage of the properties they supply. It is - all electricity...

The difference Amazon/ebay is that the vast bulk of what's offered on Amazon is either sold and shipped by Amazon, or sold by a third party and shipped by Amazon from an Amazon warehouse. Therefore you are very likely to actually receive what you purchased in a timely fashion, returns are wholly...

Yes - but only if you remove whatever transformers/drivers/converters/power supplies are there for the old lights, and preferably remove all of the junk and obsolete wiring. New lights require a 230V AC supply.

No idea who or what they are, but it's the usual scam pattern of a free check lasting a few minutes which inevitably leads to the entire installation being condemned as dangerous, and unsurprisingly they can fix it all for a massive price. Very unlikely, and if that really is true it should all...

1 - They cannot force anything, but on the other hand if the DNO won't do anything with the installation then that only leaves the building owner to pay for it, or allow it to fall into disrepair. 2 - They may choose not to install a cutout, or install anything at all, but the lack of one will...

Technically that's correct, however they probably don't exist. When it was installed decades ago it would have all been the electricity board for the area, but today it's all been separated out, and the mythical BNO for the parts between the incoming supply and the meter simply doesn't exist in...

Yes, and have done many times. Likewise with Hager. I have also installed a few others such as Lewden where an MCB was required for the SPD.

Yes, Rawlplastic. However that's not been made for many decades.

That is a summary of 90% of the electrical and other construction industries. All SPDs require overcurrent protection. What that is depends on the specific SPD and where it is installed. When SPD operate due to overvoltage, they essentially short out the supply either L-L, L-N or L-E. It's...

If you want more range, then forget about lead-acid and use LFP or similar, example of capacity with physical dimensions: https://vi.aliexpress.com/item/1005008704595225.html

The screw is more than 4mm, even compared to that crude measuring device. Left red line to the green line is 4mm. Screw extends to the second red line, which is pretty near 4.5mm In any event, the actual dimensions are irrelevant. What matters is that the screw and plug result in a secure...

It does, but the most common buck-boost transformer arrangement will not provide an isolated output. Neither would an autotransformer, although that would be an unlikely choice as it would be significantly larger and more expensive. A ferroresonant transformer would be an isolated output but...

This: https://assets.new.siemens.com/siemens/assets/api/uuid:c71a9710-04c8-4e30-afb1-80bb72e4efbc/rwb2e.pdf which shows the mopre recent model, but the only difference is the four buttons are in a different location.
