Hi guys, I would like to add: if the water colour in your system is black,
thats hydrogen deposited as sludge in your system once the water has become
over saturated and released as much as it can as hydrogen gas. You may have
bled the radiators thinking it was air. A good de-sludging non de scaling
agent, X100 or furnox will do. If the water colour is orange or red, thats
due to air entering the system via the header tank for the heating system. The
desludging agents mentioned will have little affect on this. You need to have
the system power flushed and this can take up to a day or so. The €śpumping
over€ť is mainly due to a low pitched roof which prevents the header tank to
be installed at the correct heigh. The Fill and Vent should not be installed
by the use of tee fittings. A Myson airseperator or a Tower Air separator
should be installed correctly and the distance between the exit of this peice
of equipment and the first pump valve is crucial. If the €śpumping over is
the main problem, before you spend money, check for a blocked cold feed from
the tank to where it enters your system. It really is a professional job yet
be ware of rip off merchants. Also when this work is done take care of your
system and do not trust the nationals out there who are only out for your
money. Kindest regards.
