Ivar 3 Loop UFH

[John Carroll]

This setup is apparently working fine for the past 10 years, its set to give a UFH temp of 30C from a oil fired boiler running with a 65C flow temp. I havn't seen it in action yet but just can't figure out how it actually works, the manifold pump is pumping downwards but I can't see how any cold (UFH manifold return) water is returned to the boiler.

I posted all the manuals for this last week (ish). Have a look under underfloor heating section

It's OK that we can see other people

I appreciate all answers John, the nearest arrangement I can find is the one below which makes perfect sense.
