Classic close coupled tee layout.

Close coupled tees used to solve residual pump head issues.

I have a 111 with a non-touch LCD screen and was wandering if it would invalidated the warranty with Viessmann if I were to install flat face unions instead of the supplied valves? Also where did you get yours from (I think the 111 flow/returns are 3/4")?

Old video I know so may be going over something that’s already been asked so appolgies if that’s the case. Wanted to know if using this set up, with a combi and cct’s, if I set it up after the cct with a pump for radiators and a connection to the flow to ufh manifold without a pump. Does it matter if the return from that manifold is tee into the central heating return? It would be the last tee on the return if that makes any difference? Just can’t get the return it self back to the boiler cupboard easily

I've noticed on a couple of your videos you don't like Magnacleans....... What is your preferred filter?

[@andrewmillwardwatford9410]

I think they are all a waste of time.

[@igorchuchro4991]

Ideally you'd Install branches in this order first dhw then radiators and ufh at the end am i right?

[@andrewmillwardwatford9410]

This is close coupled tees at the boiler so any order after will receive the same flow temperature. You are thinking of primary secondary layout with multiple cct's. I have other videos covering this.

[@cypher2166]

Do you prefer closely spaced T’s over a low loss header for hydronic separation?

[@andrewmillwardwatford9410]

No. Each method has advantages and disadvantages. Ccts are compact, cheap and effective. A llh adds volume for boilers with poor modulation, adds air and dirty separation. A plate heat exchanger offers total protection of the boiler from contamination. A plate is really my preference but it's very high cost, bulky and looses some efficiency. You have to.pick a method most applicable.

Awesome, thanks for the reply!

Magna leak 😂 very true

Andy, you mentioned UFH in this video without a pump. Would UFH with a pump be ok? I was contemplating this arrangement but my UFH manifold has a pump @Andrew Millward

[@andrewmillwardwatford9410]

The pump if on a normal ufh manifold is ok but no pump from the cct.

[@stuarthughes6530]

@@andrewmillwardwatford9410 cheers Andy, so just for clarity. If the branch for the UFH is after the CCT but before the pump which feeds the CH, then a UFH manifold with pump will be fine?

[@andrewmillwardwatford9410]

@@stuarthughes6530 almost all manifolds will pull water. A few few will not.

@@andrewmillwardwatford9410 awesome, appreciated

[@smgroves26]

Would you still control UFH and radiators with zone valves. And wire them like an s plan. Trying to get my head around a job to makes sure it's going to work the best it can with what the customer already has.
