how did the water leak show CO leaking?
After the repair he did a CO test and it showed a leak.
pressure... a flush will do fuck all
Thanks. I think I might have miss remembered and the flush was due to the shower getting cold. Logic being scale reducing flow and then making the boiler think the water is hotter than it is.
leak advice
Cheers. That's appricated
leak in the Heat exchanger and its leaking into the condensate
This sounds quite likely give how much is then flowing out of the pipe into our garden.
It's a Worcester (not bosch) boiler fwiw.
We dont just go out and suggest new boilers willy nilly
Sorry if I was unduly negative.

So ive seen your 2nd comment, how did the water leak show CO leaking?
In terms of loosing pressure a flush will do fuck all, so that engineer was a clown. You need to find the source of the leak first, it could be a rad valve but if your having to top it up that much it'll not be that.
There is a pressure vessel in the boiler, they tend to go flat and should be charged on a service, they do burst tho and that could cause it or there could be a leak in the Heat exchanger and its leaking into the condensate so you'd never find it. Could also be a leak under the floor too. If you have over pressurised it and the PRV has opened they close but usually never fully seat again and that could be another point of the leak.
We dont just go out and suggest new boilers willy nilly but depending the age sometimes your throwing good money after bad money and it can work to your advantage changing it.
Boiler age your looking at around 10-15 years for a boiler these days they certainly aren't built to last 20/30 years thats for sure. 15 if your doing really well out a combi.
People will change there car 5x over than change a boiler even though you probably use it more than a car.
