Mystery catastrophic combi boiler leak Discussion Thread

Hello, The other week was below freezing weather, so I put the heating on my combi boiler.
The timer was set to come on 15min per hour overnight.

In the morning, I went into the kitchen to find the boiler was dead, about 3 to 5 litres of water on the floor beneath the boiler and the kitchen mains circuit was tripped.

Engineer came out and opened front cover and more water poured onto the floor (imagine a goldfish floating out...

 

Mitras semi buried gas meter box - welded meter outlet fitting Discussion Thread

Hello, I went to a job recently that had a smart meter in a mitras semi buried gas meter box. See pic attached. The meter outlet fitting is a factory made welded fitting that allows the meter outlet to line up with the outlet hole on the box. It is not something I had seen before and I was wondering how one would deal with these if you needed to upgrade the pipe run to 28mm as the fittings seem to be...

Viessman Vitodens 100-W weather compensation Discussion Thread

Good evening,

I have a Vitodens 100-W (Type B1HC, B1KC) boiler and I'm considering adding a weather compensation control.

I'd appreciate any insights on the pros & cons.

We spend around £1,200 a year on gas, Viessmann reckons you can save up to 15%, is this achievable?

Regards

What does this debris look like to you? Discussion Thread

We've recently done a power flush on a system that's already been power flushed twice within the last 5 years. System boiler with an unvented HW cylinder and 3x UFH manifolds. Quite a large house. Strainers installed before each manifold - fully clogged.

The stuff we got out of it looks like in the picture below. My guess - the green/yellow stuff is bacterial growth, but some of it feels like sand, which I can't explain.

blisters on flush valve seal Discussion Thread

Had a leaking flush valve in the cable operated Fluidmaster drop dual flush valve in the toilet cistern that initially turned out to be some limescale debris stuck between the flush valve (drop valve?) and its seat.....
After removing the unit and cleaning it all out I noticed what I can only describe as some quite large - about 3 to 8mm - "blisters" on both sides the Silicon sealing washer, I carefully pierced them with a fine needle...

 

POC in flue integrity Discussion Thread

Windy day, wind blowing directly at a fan assisted horizontal flue.

During a flue integrity test O2 is 19% 10ppm of CO

The very next day without the wind the flue integrity is fine.


This is the first time I've ever had this but I would guess its a common issue?

I wouldn't say the flue is particularly susceptible to wind as its opposite the prevailing but a plume management would actually cause more issues with keeping it away from the...

Problem with Kane 458s Discussion Thread

Issues with Kane 458s

Bought unit back end of April 2022.

1st. Problem sent back to Kane on 7th July. After flue sampling it would take 2 minutes to slowly drop coppm. Then hang at 4 coppm for next to 3 to 4 minute's before zeroing in fresh air. Also ratio would jump around.

Kane fitted a new CO sensor.

2nd. Problem sent back to kane on 6/12/2022. On older pre-condensing boilers I'm getting unbelievable clean ratios of.
Example given...
