I love this idea. Developing it further you could have additional ‘designs’ that are variations on this theme to cover likely common requirements. Producing in a ‘workshop’ environment as opposed to punishing old knees leads to better quality too!
Just great. In terms of system efficiency is a plate heat exchanger better or worse than a low-loss header? Is it only because of the need for complete separation that you would choose one over the other? Many thanks!
I think a plate offers lower efficiency if we ignore main hex contamination. The purpose is to prevent that so in theory it's more efficient with a plate. Not proved this though.
Hi Andrew nice video nice set up. Can I ask so i understand Is the sensor on the flow sensing the water after the plate . Would you have another sensor after the mixer sensing the mixed
Looks great 👍. A question:- Why would the Radiator Rtn only flow into the plate and not the Mixing valve AND Plate ? It's a Tee, so won't it try to go in both directions ?
Is the little black box on the distribution header purely just a temperature sensor? Are the 2 pumps the same for mixed and unmixed circuits? Why didnt you use 2 mixed for radiators and underfloor.
Nice and high tec work as usual. Love ur videos as usual Just quick question pls why u use no return valves?! Is it bec u have mixed circuit for underfloor heating? Also if plate heat ex is used for for radiators circuit and hot water cylinders do u still need these NRV. Much appreciated
Would u still put NRV if u have one heating circuit of radiators and one for hot water cylinders (not separate hot water priority scenario) many thanks again
You truly are a plumbing legend......in your own lunchtime!
Very nicely done. Would like to see the whole installation. Thanks to you slowly learning more and more.

I have this plan for the future. 60 this year so knees need help.
Love it. Nothing like working smarter.
Great idea after 45 years my knees are shot. Is this weather comp when it all gets fitted ?
Yes
Great idea pre fabricating your pipework. Working in a bit of comfort then mount it up. Class
Thank you
Love this 👍🏻
As usual. Very interesting.

Yes

The volume of flow into and out of the ufh is the same so no flow can be drawn from the radiator circuit
Is the little black box on the distribution header purely just a temperature sensor?
Are the 2 pumps the same for mixed and unmixed circuits?
Why didnt you use 2 mixed for radiators and underfloor.
Yes it's a temperature sensor.
One because its cheaper than two
how do you like those non return valves, i keep finding faulty ones.
Not noticed an issue yet

The nrv stop reverse circulation when one pump.is on and the other off.
Would u still put NRV if u have one heating circuit of radiators and one for hot water cylinders (not separate hot water priority scenario) many thanks again
@@conand1413 one for each pump unless using zone valves
I thought the same but always its good idea to ask the expert. And not just any expert but the expert, i aspire to be half as his expertise
@@conand1413 thank you
How do work out what authority mixing valve you need?
I think I did an authority video.
@@andrewmillwardwatford9410 yes thanks just watched it. I’m not great with the maths unfortunately.
