Static pressure 3.0 bar.
Flow from cold outside tap ~17l/min.
Accepted that there will have to be flow restriction on the cold taps in the house to prevent loss of hot water pressure.
Just looking at mixer valves.
"Water minimum flow rate For best performance within the specified running pressure range a minimum flow of 8 litres per minute should be available to both inlets."
Now does this mean that you need a total flow of 16 litres per minute evenly distributed between the hot and cold?
In which case it is just in spec. with a 17litres per minute total flow.
Or does it mean 8 litres per minute shared between the two outlets which is well within spec.
I think it is total flow of 16 litres per minute, but just double checking.
