I understand that its normal for output flow from a combi to reduce when the inlet cold water flow is reduced (when other outlets are opened) but is there a method/process/configuration that can be adopted to minimise the effect in the the drop in flow and in doing so, provide a priority flow?
It jumps to mind that having a storage tank to feed the combi would provide a solution but as I've never seen this in any property, I'm guessing its not an answer (but would love to know why)
If I replaced the 15mm cold feed to the combi with a 22mm pipe and then had a connection (tee) from this pipe to a 15mm take-off for all other outlets and positioned this tee as close as possible to the combi inlet, would this provide a priority flow rate of any discernible value?
How about reducing the flow in the existing take-offs, is this what you do? (and by how much to make a difference)
Or is there another option that my non expert mindset has yet to consider?
