Update; feed and vent pipes have been combined and air vent fitted - no longer pumping over. Contacted Ideal tech. team concerning the pump on the flow side, as indicated on page twelve of the manual, their reply was, that the pump could be fitted on either the return or flow side.

A Merry Christmas and a Happy New Year to one and all.

Yes Steelmasons, I intended to do just that to combine the feed and vent pipes. I shall refrain from going down the historical path - just in what decade the system layout that I have was deemed to be an acceptable/standard design. As, D. Hailsham pointed out when referring to page twelve of the...

Please ignore the previous post. I had the same thoughts as you ( D. Hailsham ), namely that the water was taking the path of least resistance - thus the pump over. Thank you for your thoughts on the matter. It is nice to have your views confirmed by someone else. I would also agree with Simond...

I have a Mexico HE 15 heat only. Thus the output is 15kw.

Hi, The boiler is a Mexico HE15 heat only - thus the output is 15kw.

Sorry about the somewhat misleading diagram. Ex01 was the nearest symbol available to represent the pump - so the pump is not in the boiler. Will that make a difference the pressure differences ? Ideal does accept combined feed and vent pipes in relation to their boilers.

The long awaited diagram. To reiterate - what do you think is causing a pump over when the system is on C.H. but not when on D.H.W. What do you think of combining feed and vent pipes as a means to overcome the problem of pump over ?

Hugh, your warning is duly noted. I appreciate that if the flow pipe is 'obstructed' between the boiler and vent then the vent facility ceases to function as a safety device.

Thanks for all of your comments and suggestions so far - keep up the effort lads - most appreciated. Terry - I'm working to provide a diagram. The pipework at present is similar to a standard set up apart from the differences I stated at the beginning. It's my understanding that the format...

I wondered what the consensus of opinion is concerning combining the feed and vent to overcome the problem of pumping over ??

I would have ticked thanks earlier but the diagram only appeared this afternoon. I did wonder about the comment ' there ya go ' on its own. It would a

New boiler installed (May) -installer didn't check suitability of pipework - apologised - would return to fix it - still waiting. The main features of the pipework - feed and vent pipes are connected to the HW circuit -return and flow respectively - pump on the return side. So, at present - a...
