The boiler and all pipework rads etc are 5 years old , the boiler is needing to be pressureised three times a day , there are no leaks on any rads , valves etc . The expansion pipe is not dripping at all . It seems to lose pressure when the hot tap is being run which would point me at the dhw heat exchanger , worcester tech help think it will be the main heat exchanger is faulty and the water is coming out of the condensate pipe , how hot should the condensate water be . They say it wont be the dhw heat exchanger because then it would overpressurise. Any advice gratefully recieved as I dont want to get the main heat exchanger changed when the part costs nearly £500 unless I am certain it is that part . Cheers

I'd be inclined to agree with the WB guy, when the boiler is off, and cold, does water still discharge through the condense pipe. There have also been numerous people on here insist the prv is good when it actually discharges all the water from the system in a single shot instead of a continual drip.
