Hi,

I have two questions I hope people can help with. I have a pressurised
heating / hot water system consisting of glowworm boiler unit and
megaflow pressurised tank upstairs.

1) I remember that some time ago an engineer explained to me that once
ever year or so I need to release some air by opening a valve on the
megaflow tank upstairs but I can't remember how to do it. Can anyone
tell me how to undertake this ?

2) Our boiler is below our bedroom, in the garage. Every morning when
the system comes there is a lot of noise through the floor from (I
think) the circulating water through the system. We tried replacing
the pump, which didn't make a great deal of difference. The noise is
really pretty loud and it sounds like there is water in it. Does
anyone have any ideas how to fix this ?

Thanks and best regards

Leon
