Bath/shower valve filler, flow rates - is 12L per min 2 low?

[djkay1982]

just looking into this triple consealed valve I have.

manufactorers - Vado.

the flow rate is 13l per minute, they say that will realistically be 11/12 litres per minute, which they say should be fine for the showers, but not right good for the bath?

what are your views?

im going to fill a bucket with existing taps on bath tonight to compare. but if its defo not going to be any good. im going to have to get a new one ordered today!

depends on what pressure you have, did the manufacturers say at what pressure the flow rate would be 12 ltrs per minute ?

 

[djkay1982]

he quoted at pressure of 1.5 bar (combi boiler max) at that it would be 13.5 litres per minutes.

so he said in a real world 11/12 L per min

think you will find its the boiler thats the limiting factor and not the shower, if the boiler is set to give 12ltrs per minute then thats all you will get, you wont fill a bath any quicker whatever bath filler/shower valve you use.

flow rate is really dependent on the delta T across the boiler. You might find in summer you get a marginally higher flowrate than in winter - as the water is colder.
