Multifuel boiler has water in flue

[Anne lund]

I have a single thickness flue on my multi burner but even though I have a good size hat I still get loads of water in the bottom part you can take off to clean the flue.

My son took it apart last week end because of the black smelly stuff coming from the joints so he sealed them and by rights it should not now drip but today the bottom was full of water.

The coal I have been using is very wet, will this be the problem? Or am I not burning it hot enough. I need advise please.

You should never burn wet fuel. It can cause excessive corrosion and the deposits produced increase the risk of a chimney fire. Natural coal shouldn't be used in any case, only approved manufactured smokeless fuels such as anthracite should be used in multifuel stoves

If the chimney cowl is keeping most of the rain / snow out, then run your stove with the dampers open to really raise the temperature.
The wet coal won’t help either.....shovel it from the top of the pile.
