CENTRAL HEATING PUMP

[jlc24uk]

Hi all,

Need to pick your expert brains, I know a small amount about central heating systems, but not too much!! I am having a new system installed - gravity feed.

Plumber has nearly finished it but what I looked at the install so far the location of the pump doesnt appear to be in the correct location.

In the airing cupboard - on the boiler flow there first is a 15mm tee for cold feed then after that is tee for 22mm for vent then the pump, then off to 3 port valves etc.

I always thought it should go - vent cold feed pump

Am i right in saying that the way the plumber has installed it could cause problems of the pump sucking in air.

Will look forward to your replys

Thank you

You are correct.

And may I say you might now more than you realise. I have worked with engineers with 40 years in the industry and most of them had not grasped pipe configuration!

Thank you for a quick reply

Out of intrest is the design fault significant ie in theory it is installed wrong but would it suck air in to cause significant problems?

Thanks again

mmm the vent and feed must be more than 6" apart if he installed it like that.

I would ask him to change it as the chances of that configuration causing probs in the future is high.

Yes it will cause sucking in and constant air in the system will result in early corrosion and failure
