We have recently had a new Vaillant ecoTec boiler and central heating
Whenever the system is on, a stream of water drips from the flue
What is likely to be causing this and is it easy to sort out?
Much of it does, however, they don't extract _all_ of the water
vapor, and the exhaust is continues to cool as it goes thru the pipe
and hits outside yet colder air. Meaning condensation continues
to occur right to the flue outlet.
Basically, whereever the exhaust is colder than the dew point
w.r.t. humidity, condensation will occur. The drainage lines are
for those portions of the exhaust path _inside_ the equipment,
the plastic flue acts as drainage for the portion of the exhaust
path outside of the equipment (path from the equipment to outside).
