ok just turned all rads off ,went out to burner and it was very noisy like water bubbles our something boiling like a kettle(no steam)can you bleed the system like u can on rads ,their is two pipes at burner one going to bottom ,but the one coming out the top has a pump and a end piece on it with a small black cap (like a tyre valve cap)is this the bleeder valve ?


cheers mitch

sounds like an auto air vent

 

[mitch13]

auto ,forgive me if im wrong but it has no wires or anything coming from it ,i took the cap of and it has an hexagonal key grub screw in it ,i undid it nothing happened for a few minutes then water came out i replaced it and now no matter what position it is in the water still trickles out ,what?since i turned all rads off i now have hot water(boiling hot tap water)now turned all rads on still not hot approx 2 hrs tried to bleed down stairs rads their fine ,upstairs nothing is coming out not even air think i've out done myself on this one ,will go and try upstairs rad again (im taken a cuppa up this time)ok here goes

morning all
i did wonder why the guy in the tool shop looked at me that way .thing is the auto air vent is still seeping since i used the allen key on it (hexagonal)it did let air out ,then water but has not stopped yet,the rads and the hot water are back to normal it took a long time to bleed the rads but i now have hot water plus rads ,is this unit easy to replace what is involved ie do i need to drain the system

kind regards mitch



if it ain't broke dont fix it
