True, but it will for all of the none resistive loads.

I would say that the resistive loads are the ones that use the most
power. So hair driers, cookers, kettles, immersion heaters etc.

I only fitted the thing because the customer wanted it. I am happy with
my 253V supply:-)

I'm not happy with my 245 to 256V supply. I use a 1kW 1500VA UPS for my computer, so when I get 1 or 2 second brownouts, it doesn't crash and corrupt the disk. When I lost quite a few LED bulbs in a short time, I tried running the lighting circuit from it. It has a built in automatic voltage regulator (it changes the tappings itself). The bulbs last about 4 times longer.

No, that is wrong.

A kettle will use MORE eletricity due to MORE losses due to the longer
time it takes to boil. Ditto immersion heaters. Cookers that have
thermostats to reach a particular tempeartuire will use no less
electricity. Hiar driers that fail to fry will use moire as it will take
longer..

Meaning women will take even longer to get ready.

Run away now.

With all our heaters now off, I'm getting 222V in the lab 214V in my office.

With saving like this we can employ more administrators :-/
