Here's a challenge for anyone man enough to try and solve!
We have an 11 year old, Alpha CB24, two weeks ago, we noticed dripping from the bottom of the boiler, and the pressure gauge was well over 3bar. I then drained some water from the system, this reduced the pressure.
Everything was fine until yesterday. I woke up at 7am water all over the floor and the pressure gauge over 3bar again. So again I drained the system (down to the green zone). I turned the room thermostat down to minimum, turned off the central heating at the programmer. By 9am the pressure was back up to 3bar+............WTF?
We've had a plumber round who suggested the expansion vessel had gone and suggested we change the Pressure release valve. Does this sound reasonable? I can understand the pressure increasing while the central heating warms up, but the fact that the pressure increased even when the system was off/cold makes me wonder if the heat exchanger could be split or perforated?
Any thoughts? Thanks in advance....
