condensing boiler leak

JBaill · 10 Apr 2009

I'm losing pressure in my wet underfloor heating system but have no sign of leakage. However I have noticed that the condensate drain line from the boiler has a flow of around 70 drips per minute and probably fills a pint jug in 5 or 6 hours. Is this normal or could this be the source of the leak across the condenser heat exchanger? I'm not sure how much liquid drop out is normal. This line is purely for the condensor and not the safety valve which seems to be holding OK. Condensate just looks like warm water and wouldn't imagine that much moisture in the air. It is a large system covering 300M2.
Any thoughts would be helpful.

try turning system off, when it's cold check the condensate pipe, if it's still dripping chances are the h/ex is leaking.

What boiler is it? Some have a combined prv and condensate outlet.
