We have moved into our current home a few months ago. It's a very old house with relatively haphazard plumbing. Things worked fine until recently when I noticed that the pressure in the sealed system is on 0.5bar and it's not heating the upstairs radiators.
Got a plumber that had done some work on this house before, and he said there was no filling loop, he connected a pipe in the attic to connect mains system to the sealed system and repressurized it.
Looked ok for a couple of days but the system completely failed yesterday, and now when you repressurize it it goes back to zero bar almost immediately (as soon as you close the filling loop).
Plumber says this is definitely due to a leak. I find it a bit strange though, as: a) It has to be an absolutely huge leak if it looses that much pressure instantly, and b)there was no problem with the system and it wasn't losing any pressure (steady at 0.5bar) until he fiddled with it!
Based on that, can anyone think of anything that your man had done to screw it up, or is it really a leak that coincidentally appeared after he did the work a couple of days ago?
There are no signs of leaks anywhere in the house btw, he thinks it's downstairs and wants to dig up the floors!
Any advice would be greatly welcome. Not the best time of year to be left without central heating!
