Baxi and Potterton, stipulate that these air ejectors should be on the
combined feed and vent pipe to expel air. They work very well. With
combined feed and vent a very low head can be obtained, so ideal for
loft
fitting of boilers. To alleviate fears of sludge accumulating in the air
ejectors it is best to fit a Maganclean on the boiler return pipe, which
grabs magnetite that causes sludge. The Magnaclean protects the whole
system
too.

There is no reason that this problem should happen or one of these
devices needed as long as the system is correctly dosed with
inhibitor. It is dealing with the problem in the wrong way.

Matt, on a boiler change a Maganclean I would say is essential as
desludger
never gets it all out. If the system is not re-dosed, and 95% are not ,
then the Magnaclean prevents blockages. Got it?

This is bull****.

Matt, again..."If the system is not re-dosed, and 95% are not, then the
Magnaclean prevents blockages. Got it?


I don't buy that either. You are pulling numbers from parts of your
anatomy from whence the sun don't shine....
