dirty Boiler
when servicing a gas boiler , we will clean out the filter as long as its accessible and not buried behind your kitchen units as some are, here is a Magnaclean filter we cleaned whilst servicing a Viessmann gas boiler in Leverstock Green, Hemel Hempstead.
As you can see there is quite a bit of sludge trapped in the filter, we cleaned it off, refitted, and tested the operation of the boiler and central heating with a system walk.
