My central heating flue in the loft, which I though was to allow water to escape, is actually sucking air into my central heating system, any suggestions why this might be, I constantly having to bleed the radiators.
 
Pump speed too high, or incorrect design of pipework. First thing to do is reduce the speed of the pump if you can, some pumps have a three-speed selector switch on the side.
 
Thanks for the reply. The pump and three way switch are both new, the pump is set to number two of three which was fine until recently. If I set it to one the upstairs radiator don’t warm up.
