Oh dear :rolleyes: some very passionate replies - thank you for all of them!
We've managed to keep things on by resetting all plugs and switches whenever the boiler didn't fire. So we've at least kept the kids warm!
BG have just been. It was in fact said valve in picture 8 (called whatever...
I'm sorry, I'm not a plumber and am learning as I go here. Just trying to keep the heating on as best I can until Thursday.
Someone further up had mentioned a zone valve and google searches look just like the silver box in picture 8 on my original post
It wasn't empty, but it seemed to need some more water. It was tricky to see in the loft - it's not in an easy-reach place.
We have BG coming out on Thursday, fingers crossed they can sort it
Sorry, also missed this comment!
It was intermittent for a while, then totally dead yesterday.
We kept tinkering with bits and it fired up about 9pm yesterday and has been working well all day today.
Now, about 5pm, it was out again and I've got it going by adjusting the zone valve as above
Sorry, didn't spot this message.
We topped up the small tank in the loft last night, unsure if this is what got the boiler going again, but it'a gone again this evening (see comment just now). Unsure if this could still be the problem?
Scrap that, the boiler just came back to life.
I have the zone valve in "Man Open" rather than "Auto"
Can I safely leave it there, or am I now a human thermostat control?
So the boiler sprang back into life last night after many more "ALT. CTRL. DELETE" and we've had heat and hot water all day.
Just home now and the boiler is off again, but schedule is asking for heat, we've tried to boost manually, but nothing.
In the airing cupboard there's lots of rumblings...
Thanks for replying.
Any idea what it might look like?
Other than the loft, which I've not made it up to yet, there's nothing else other than pipework in the house
Boiler is now off.
Just to add to the fun, we can't use the emersion as it trips the electrics. Another thing on the long list of stuff that needs sorting out.
BG can't get here until thursday. We have standing heaters we can use until then.
Would you turn power off to the boiler until they attend? It does try to fire up once an hour or so (I haven't timed it). Concerned if I leave it on, it's a potential fire risk if it's faulty
