Medium Biomass Boiler

[cornish wood burner]

The problem is that the intake is a pig to get to: behind screwed in insulated panel upon which the fan is mounted, a lot of dicking about.

Sounds like something has changed. Either you are using wetter wood or the air flow has been changed or blocked by something. You say your wood is dry so chances are you have a blockage.

Presumably you did your own service. Have you a check list or a service schedule. Might pay to read through any info you have on servicing and see if you missed something.

Things like the fan needs to be accessed for cleaning. Could have clogged with debris.

When you cleaned the heat exchanger tubes did you clean the air intake passages as well? Could be blocked with tar perhaps.

 

We spend several days servicing our boilers, removing and cleaning fans, checking, safety systems, electrical connections, cleaning tubes, air ways and many other bits and pieces.

A view from the other side. Our neighbour who has had similar ongoing problems with smoke (not vapour) billowing out of his installation for hours on end. He didn't take the issue that seriously but is facing a massive bill for the physical cleanup of all the businesses and houses downwind of him. The Council and Defra are the least of his worries; one neighbour alone has lost £30k of fabric stock which now smells like it has been sourced from the bottom of a bonfire.
