Just put on a gas central heating boiler after about a year being unused. There is a constant drip of water from the main gas burner assembly when the gas is lit and it does not seem to get less as things warm up. It is obviousely condensate (its 2 degrees C outside) but it will rot the boiler casing if not stopped. Boiler running very well otherwise. Very puzzled by this!

Drips are very much less now the boiler has been running several hours.

Could be a cracked heat exchanger

Good idea, tks. Cannot however see a water flow from the heat exchanger onto/into the burner tube. If it were a cracked heat exchanger then the high heat would reduce the leak by expanding the iron and closing any crack.
Will switch off and look closely again at the heat exchanger as it cools.

I am surprised that no one has pointed out that water dripping onto a gas burner is classed as IMMEDIATELY DANGEROUS !!!
Us CORGIs have to turn it off and issue a warning notice!
Householders can blow them self up!

Have found the problem - a weep at the LHS of the heat exchanger where the sealant between the two halves finishes. Have sealed the spot with Gun Gum and if that does not work then its a new boiler I guess!
If it is a new boiler then what is a good replacement (5 radiators and hot-water)?
Edit: Thanks Tony, your warning is appreciated

you can buy internal seals for this boiler, its a messy job but if thats all thats wrong it can be fixed. On the other hand its not as efficient as a condenser .
As advised above the HE can be taken apart and resealed.
I presume that there are some bigish nuts holding the sides together. You may find re torqueing them may help.
I thought gungum was for car exhausts?
