Good evening everyone,
New to the forum, hopefully someone can help with a problem which has just developed with our central heating system.
We have a sealed / pressurised system which has been working pretty much perfectly for many years. Aside from needing to increase the pressure a couple of times a year from say 1bar upto 1.5bar, nothing else has needed attention.
This evening I came home to find our kitchen ceiling looking damp, so a quick run up the stairs to the airing cupboard revealed some issues. The CH pressure gauge was reading 3.4bar, and therefore the PRV had opened and was releasing water down the drainage pipe via the tundish. Unforutnately the tundish didnt line up very well with the pipework and so most of the water was on the floor, and subsequently on the kitchen ceiling.
First thing for me to confirm is that my filling loop is NOT connected!
My next thought was to try and reduce the CH pressure by bleeding some radiators and letting some water out. This had no effect on the pressure.
Next i turned off the cold water supply to the house to see what effect this had. Nothing immediately. I then ran a hot tap, and noticed the pressure on the CH gauge beginning to drop. However as soon as i turn the cold water mains supply on again, the pressure shoots back up to 3+ bar.
I've turned the boiler off of course whilst all this is going on, however obviously this means no heating and no hot water, so i'm desperate for your help!! :confused5::confused5:
Hope someone can reply soon.
Many thanks,
Nigel
