I have a 3 bedroom terrace house built in 1988. The central heating rads and pipes were put in when new, except for one additional radiator in extension about 10 years old. New condenser boiler and pump fitted 2 years ago and its a gravity fed system.
Yesterday, with no warning and with the central heating having been working as normal for 2 hours, the central heating system system just emptied itself completely in about 30 minutes. Fortunately the boiler stopped by using its safety valves etc. There is no water showing anywhere and trying to fill up the header tank again fails as the water just runs out continuously.
The piping downstairs is buried in the concrete flooring.
I have called our plumber who is as mystified as I am and is coming tomorrow to look at the piping for the extension as a first move, but this does mean taking up some of the concrete floor.
Anyone had experience of this sort of problem? Where has the water gone? And what's the best way forward? Any advice would be welcome. Thank you.
