G'day all!
Up early to investigate the gas sylinder leak problem.
Found precisely one "rubber" type seal in my plumbing stores that'd prolly fit having looked inside my regulator thing for the barbie, so got tools and of to the camper van that they had parked up naughtily next to the footy pitch. They were up, sho nuff they had lost the washer when last changed it, so it took about 1" to fix!
Great!
So back for brekfus where, by giving them scrambled eggs on toast, I cunningly saved 2 croissants.;) They had one each all the same.

They left some time ago for the Loire valley.
Meantime I decided, in a moment of inspiration, to test the cheapo thermostat I bought last year by simply not testing it on the heating, which takes so long to react you cannot be sure of anything, but by simply using a lamp! Duhh!!

The wiring digram inside the outer part of the stat's cover is of the simplest, but there are two symbols in it that I cannot find ont internet.
Each one is in a box.
One looks faintly like an 8 with both circles the same size.
The other looks like a U but with the tops of the bits that stick up touching the top line of the box.
Can anyone please illuminate me with some meaning?
The "figure 8" one has a line off it attached to the arm of the switch, the "U" type one is in a line from the neutral to the switch, so I think it might represent "load".
And of course the switch is the thermostat which is prolly bimetallic. It's got a flat metallic disc connected to the dial you turn to regulate the temp. Maybe the firgure 8 bit just tells you it is the bimetallic bit.

It MAY be possible to photograph the lickle diagram, but it is in an awkward place in the outer cover.
 
So, managed to photograph it, so here tis, help with what is in the two boxes would be very appreciated
Tia.
P means "power" in French which for us would also be positive, N = neutral, pretty obvious.

Another hot day forecast
Doors, windows an blinds all shut, still 25 in house
Not going steam fair, it would be madness at my age to stand in a field with thousands of people, fridges and generators running, tractors and vehicle engines pumping more heat out and no wind to move it all.
Might get some painting done though

My loft is gleaming now. I’m just in the process of spraying down everything with a Dettol solution. I’m not the biggest fan of Dettol smell but it’s an improvement on smelling like burnt hair on a turd. Problem is I go up there, spray and come out soaked as it’s a 1000 degrees in the shade.
 
Possible, but not certain:

The square labeled U: May represent the relay or contactor coil. Which energises a device.

Square with 8: This could indeed be a thermal relay.
Indeed, the square labelled U must be the relay that controls the huge current that an underfloor eletric system uses. And yes, the B or 8 in the box must be the bimetallic bit that changes the switching according to the surrounding temp.

So thanks both of you, this is a big "phew" and makes all of it make sense.
I had the sense to test the stat by wiring it in to a circuit I made with a table lamp in place of the U box. It worked fine.
So now I can go ahead and order a load more of these to replace some of the 11 more complex ones that have gone fubar.
They all seem to have a similar fault so I think once I can get a tame PCB tech to repair one and tell me what was wrong wiv it I'll be able to do the rest. I expect it is just a condenser although someone else said it could be some contacts, which would also make sense.

As you can imagine we, not having air con in the house, have become quite good at keeping the house cool.
We close windows and curtains when the sun is on them but open doors and windows that are in the shade, which means the north facing side and the east facing window in our bedroom when the sun has moved round.
We find that having upstairs windows open promotes a draught in at the bottom and out at the top, which akso helps.
But the house was designed so that in the summer the big double french doors which are south facing are always in the shade. Sure it is still warmer outside there that on the north facing side, but the draught it allows in feels cooling.

In the end we do still have a good fan in the lounge and an excellent 5 speed silent one in the bedroom. It sucks cool air in from the eastern facing window during the night.

We have no idea how much more it would have cost us to have air-con fitted. Back in the 2000s it didn't seem such an issue especially being 600 metres up, which does thankfully make a big difference.

Shame about the steam fair! :(:(:(
 
Just hadda cool baff to cool down. Left the baff room door closed because the sun is about to hit the window. Nice and cool in the hall. Upstairs ok but downstairs is coolerer.
