I will be refurbing two upstairs bathrooms and want to boost water flow to the (currently gravity fed) showers. What factors should I consider in choosing between (a) box-on-the-wall thermostatic units with integrated pump - which seem quite neat - and (b) a separate impeller pump to supply both showers?
I have an ordinary (non-combi) boiler. Cold water tank is in the loft and HWC next door to one of the bathrooms.
Thanks
Adrian
