Nice; 2kW of heating for 7p/hour 
The socket for our washing machine and dishwasher stopped working a few weeks ago.Not an unqualified success. After a couple of hours I realised the plug on the secondary extension lead I was using to get the power all the way into the living room was overheating and the fuse would probably have blown if I'd left it any longer. The basic concept is sound, but that extra extension lead is not good. The actual VtL adaptor and the heater plug into the other end of the problem adaptor were both fine though. Some warming on the latter but nothing to get alarmed about.
I'll remove the problem plug and fit a new, heavier-duty one and give it a shot while monitoring the situation more closely.
Fuel stations in the early days were not govt subsidised though.This sounds a lot like the early days of EV adoption, did they have fuel stations before they built ICE powered cars? No, the adoption of a car that could travel further than a weekend hobby toy for the rich and started to replace the horse, the town store and town stables became fuel suppliers and mechanical workshops.
Likely quite a high resistance connection resulting in heat build up, which in turn increases resistance. It does not take much, a slightly loose or partly worn socket or pin, dirt, corrosion.Hmmm. The hot live pin of the plug has caused a bit of damage to the plastic plate of the extension lead socket where it was plugged in. It seems to be superficial and just cosmetic, but I think I should have it checked by an electrician and probably get that plate replaced before I try anything heavy-duty again.

Had an electrician around yesterday who traced it back and found that a connector for the wires on the circuit had melted/burned. Left black marks on the wall above and below.
Now fixed and working. Waiting in trepidation for the invoice from the electrician, though. He was here for several hours so it will be over £100.
Serious stuff, electricity.
