Thanks! Just the info I've been looking for. This and your Why Not To Use LLHs answered some questions, saved me time, money, and some headaches I'm sure!
What about flow against flow of the 2 circuits? Or flow with? Pros & cons to each??
Have you though of knocking up an adaptable test rig, instrumented with flow meters and pressure gauges?
Yep.. got something on the way with that actually...
I would like also to ask question regarding this video if l may. In therm of UFH, where is correct place to put CCT, closer to the boiler, closer to the manifold or somewhere between two of them? Thank you for your answer. Great video again. Cheers
Almost never site a cct near to a manifold. I say almost never because it's ok if it's the only circuit on the boiler or possibly a system with only ufh but multiple manifolds if balancing is possible on such a system. On systems with mixed circuits the hydraulic seperation should be prior to all circuits. The best solution if you need seperation at the manifold is demonstrated by Adam on a video called an alternative to ccts. This video shows the method demonstrated in the Viessmann technical guide and allows the ufh to reuse its own circuit water to limit the impact of the ufh circulator on the flow in the main system.
We have a video out on this now
Thank you guys. Appreciate that
Adam, the _return_ pipe of the close couples tees (on the right), say to a UFH circuit. The water coming out into the primary loop pipe splits - 10 litres/m to the left and 20 litres/min to the right. So water is going against the flow of the loop for a few mm. Also, what is the *flow of water* if it is in reverse? If the primary loop is 30 litres/min and the UFH is 20 litres/min?
If in reverse its 10l/m also.. 30-20= 10..

The short section between the two tees. The flow will be all going one way. No reverse.
@@johnburns4017 it will reverse is the secondary side is faster than the primary side John.
Nice one bruv !
good explanation can the close couple tee replace the low loss header, and add a secondary pump same size a boiler pump so no conflict with each pump
You will still have conflict as they'll be controlled differently and have different resistances
@@HeatGeek if i use a low loss header and the boiler pump 15/60 (42kw cdi), would the 25/80 on the LLH pull to much water away from the boiler.
the house is a old victorian, high ceilings with a loft conversion, some radiator on second floor are just warm to zero . i need to get heat to the loft area worcester-bosch just fob you off . this is why i ask the industry plumbers as a retired plumber i know how difficult problems are to solve. this one baffles me, could i blank off the boiler pump install an external pump with enough head to heat the whole house. the whole system was installed incorrectly with to many bends ect to slow the resistance down many thanks
how far apart can you space 'not so close coupled' Tees before you run into problems?
Too many variables there bud.. we go some way in to answering it in part 2 of the course though.
I've done them in many incorrect formats and had success each time as far as I can measure. I follow the rules whenever I can though.
well, who do I see here :D Nice installation soon with 25-80 on primary so I came to check how much oversized closed couples tee's should be and there you go
By the way I'm in process of buying flat... I'm gutting everything out, and would like to know your opinion on UFH in the flat, if that would be worth. Ceiling height is 2.6m
What's your background Heatgeek ? Are you from an engineering background or have you been involved in the heating industry since you left school ?
Hi Jamie. No i started at about 18.. bit didn't some travelling etc too so had gaps.. im 35 now. This kind of stuff was just picked up by conversing with other engineers on social media.. have a course teaching everything I know being released in two months time! Sign up to the new letter 😁
@@HeatGeek Cheers mate, looking to do the course soon. Goodluck with what you're doing, the course is getting great reviews.
Is this for a low loss header design to pump round boiler.
Its instead of a low loss header bud 👍
@@HeatGeek what do u think is better?
@@scottgas58 each have an advantage and every situation different.. llh also has dirt and air separation properties though

And you going to make things easier to understand for guys like me who don’t have a plumbing degree? 😉
Yes actually!! 🤣🤣 coming soon...
@@HeatGeek I mean I think you’re on to a great idea here....so I’d love to be able to understand it better. Maybe you’re pitching your ideas to a high level of plumber/heating engineer....but please don’t leave us novices out in the cold 😉
@@simonstones1918 yes mate totally understand.. we will be covering from novice to pro.. thanks fornyour engagement.
@@HeatGeek no problem. I’m always hungry to learn. If you’re not growing you’re dying! 💪
I’ve just released a course detailing everything you need to know to become a heating genius! What’s more it’s been recognised by the UK government department BEIS which have offered to heavily subsidised the first 300 spaces!
