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.
