My valiant ecotec 831 boiler is only a few months old, need pressure topup everyday! My plumber hasn't a clue what is the cause! A valiant engineer has come and checked and he said the boiler is fine, suggesting that there is a leak in the system. I have done a pressure test to the boiler and noticed that while the boiler and the central heating are isolated 20 hours , the boiler itself dropped by .6bar. Does that mean the leaks is in the boiler itself not in the system.
I have checked the relief pipe and the bottom of the boiler, didn't see any leaks there. I have also checked the valves of all the radiators, no sign of leaks there either. I have checked all the ceiling, can't see any wet patches anywhere. Someone suggested that might suggested a fault in the heat exchanger, but how can I tell if this is the case?
In fact, the pressure problem started right after the installation. At the beginning, we have to top up the pressure like every week. After a few weeks, the problem disappeared, it's working beautifully for 3 months or so until a month or so ago, it needed topping up everyday!
Please, I badly need some advice here; I am afraid neither my plumber nor the valiant engineer are able to solve this mystery eventhough the boiler is newly stalled and is under manufacturer guarantee.
