sorry, more info:
the combi also supplies the existing bathroom/kitchen DHW so for instance, when the bath is being used, theres no real pressure on any of the other hot water taps. Hence, this would mean that the new en-suite shower could not be used at the same time as any of the other hot...
Hello,
we currently have a combi providing all the hot water and heating for a 4 bed house.
i've just added new empty en-suite (shower and sink) and would like to ideally have mains pressure hot water in there for a multijet shower system (so electric heater does not seem appropriate?)...
