Thanks, interesting reading. I like the manifold straight out the top of the UVC, simple and effective. KR wes

Thanks for the tips NFW. 🙌

Thanks, thats really helpful. They say, a little knowledge is a dangerous thing, and thats all ive got at the moment so places like this are really useful for asking some of the finer details. If i go for the HRC i'll go 15mm and control it so that its not on all the time.

@Nickfromwales apologies for resurrecting an old comment on an old thread but... Am just embarking on my own H&C installation and have landed on a manifold system as the preferred option, have also settled on the fact that three of my hot outlets may or should be on a HRC as they are some way off from the manifold setup (and id like hot water to come out of the taps fairly quickly), those being two bathroom sinks and the kitchen sink (all roughly 15m). If you don't mind, my general questions on the HRC are: - Firstly is it actually necessary, then... I would be installing in hep2o and am fairly sure that the HRC is ok to be done in the same barrier pipe, is this correct? Flow and return both in 10mm hep2o or should the flow be larger? does it matter? My design for this set up would be to feed the whb's and sink from the main hot manifold but reduce to 10mm, have the HRC come back via 10mm to a return manifold specifically for these three returns, then from manifold run to an isolation valve, followed by a non return valve, then my secondary pump, a final isolation valve and then into UVC somewhere in the upper portion of it if at all possible. Is this logical. To save faffing on any technical controls, run the HRC from a programmable pump. Hopefully I've explained my intentions correctly and would really appreciate any guidance you could offer. KR
