It was definitely calling for heat. Motorized valves opened, CH pump was running. Same with HW, there’s no HW in the cylinder so turning on the HW opened the MV but the boiler didn’t fire. Turning the boiler and burner off and on again seems to fix it. There is no burner lockout light as far as...

I put the cover back on, turned power back on and now it’s fired up. Been running 15 mins so it’s hopeful.

Here’s a photo with the cover off. Other threads say try firing it up with the photocell removed, should I try that?

I have a warmflow oil boiler with Riello burner. It’s a regular setup with 2 tanks in loft. The CH was running last night when it stopped firing. The CH pump kept running but the Riello never fired up again. This morning, from cold, it still won’t fire up. Same issue with HW and CH. the...

I let him know about the airlock problem and absent NRV so he's going to work on that instead of the service.

I emailed the manufacturer before posting here and they got back to me: The valve pictured in your email below is a pressure safety valve which was offered by Pegler prior to 2010, before it was discontinued due to changes in legislation which required safety valves to discharge to a drain and...

Thanks all. I think it’s a red herring then. There is an air lock in the HW circuit and I think it’s near that valve but the valve is not related to the problem. I will drain and refill HW. The valve was 5 quarter turns open so I have left it at that.

This is the cylinder. The system has worked fine for years. The gravity HW has always been a bit slow, but not as bad as it currently is. The problem started after I removed an old radiator so it's highly likely there is air or sludge in the HW circuit. The boiler fires up but there is a big...

Its a regular boiler on an open vented system (2 tanks in loft). The CH has a pump but the HW is gravity only. The cylinder is in the room above. It doesn't make sense to have a pressure release valve on an open vented set up does it? Gravity systems need a non-return valve usually.

Anyone know what is valve is and what the nut is for? It says Pegler England on it. I have gravity HW and this valve is on the flow side just after the boiler. I guess it's a non-return valve? The HW is not working well and the temperature before the valve is currently 60C but after the valve...

The tiles won't sit flat because extra bits of batten have been nailed on top of the purlins. This may have been done to install the weird gutter made out of lead. I'll try removing them but it will require removing quite a few tiles and rain is due.

Yes, I have blocked up the roof hole and they have nested elsewhere. I live in the countryside so there's no need for them to nest inside asbestos roofs. Never seen a section of roof lift up like that. I'll try taking the tiles off and putting them back again to see if they settle correctly.

They are waking us up at 4am. If they didn't make such a racket we'd never have noticed them. There are plenty of other nesting spots around the house.

I have blue tits trying to make a nest in the roof. There is a massive gap which I have blocked up for now. The rows of nails looks suspicious. Normally there is one or two nails near the top of the slate whereas here it looks like someone has tried to close the gap by nailing the slates down...

I was wrong about the driveway. The 'under drive' is solid concrete and has a decent slope away from the shed and towards the stream. Maybe its flowing to the left but the low wall on the left is stopping the drainage:
