The flow rate will double if you have 2 pumps inline , if the flow rate increases the DT across the system will change , higher flow rates increase noise and erosion inside the system aswell, CCT’s or low loss headers will stop pumps affecting one another your not trying to increase flow rate your trying to overcome resistance in the system
The pump in the boiler is having to overcome the resistance through the heat exchanger so doesn't leave enough head for the system. The secondary pump doesn't have that so has more available head.
Nice job Steve could you explain sometime how you wire the boiler and controls to work with the primary loop and zone vales please
Nice design and neat work. Respect.
Really nice, seen a lot of your servicing/breakdown vids but this one made me sub, more please!
A very nice looking job 👍👍👍👍
How do you control this system mate?
Lovely work by the way.
great job mate,
Quality work right there 👏
Looks good enough to eat ur dinner off it
I dont know mich about close coupled tees, but if the secondary pump is the same size as the pump inside the boiler wont the flow rate be the same?

I'm impressed at how you keep the pipework so shiny? Especially after touching it?
Well it surely has to be lagged
Superb
Thank you buddy ❤️
Quality 👍
great job mate
Thank you buddy ❤️💯
