Clearly I'm not an expert - my objective is to a) add storage by eliminating the cylinder and b) maintain high flow in the shower. I read you cant put a water pump after a Combi Boiler so I was hoping there is a way to leverage from the water tanks on the roof. Any idea?
I've been suggested the following: mains flow is about 9-10 l/m so quite low for a good shower. Instead of connecting the boiler to the mains, I can connect the boiler to the roof tanks, add a water pump in between to create higher pressure/flow. The Combi Boiler (36kw) output is 14 l/m so that can then be pushed to the showers and I believe it will be a decent flow rate. Would this work?
