This is much appreciated espeacially the speed in replies. Now it has been confirmed that this is a installation fault the installer has been called and will be round today to answer some serious questions.
Thanks again
Hi - I had this fitted brand new 1 year ago and all seemed fine until 1 month ago (cold snap started) when it started leaking from bottom of boiler it only seems to leak water in morning when heating fires up.
Anyway few days ago the rads did not come on i checked boiler and pressure was 0.6...
