Probably paid £30 plus for the 200 watt heater. shoukd have just bought the cheap 1000watt heater and had it on for 1/5 of the time.

Get a storage heater without the convector or keep this turned off as this is will run on the normal 24 hr electricity price and not the cheap off peak night time electricity

You could use 35mm boxes and screw straight into the wall and tell the dot dabbed to bring the board out to the level of the box.

You are correct, boxes should ideally be a few mill behind the plasterboard. you can buy extension boxes that screw onto the original box to bring it out to the depth, these are a pain. don’t let them use long 3.5mm screws and have a gap.

Or an expensive fan with a backdraft shutter as part of the design, vent axia do them. Can’t remember make and model.

Yes a normal consumer unit can be fitted inside an IP rated enclosure.

Not crazy at all quinetic receivers and wireless switches will give you a normal looking install!

Google the numbers on the fitting, it’s the model number for a JCC fitting.

If you have a modern boiler it may have a modern pump that along with the boiler modulates down so it then makes it harder to get heat to these further radiatiors when the rest f the house is satisfied.

Did you try my suggestion?

Only if you run the pumps and check operation in a regular basis. Register for flood alerts from your environmental agency, that’s helpful. pumps controller with sms autodiallers that text you when you get high levels/ trips etc. Temp pump, and never use lay flat hoses they are rubbish..

Turn off all the other radiators on the TRV and get that radiator on fully open on the TRV. put the heating to max/30 deg to make sure it’s pumping out max and try again

You will need your own earth too, as you cannot be sure that the fault hasn’t taken out the network earth.
