Can worcester greenstar 30i combination boiler support shower and hot tap at the same time?
Hi I have a small two bed flat, just got this Worcester Greenstar 30i Combination Boiler fitted one week ago.
I noticed each time when I take shower, if anyone use the tap for hot water, the shower water just gone, depends on how much hot water the other end using, the shower can change anywhere from "almost totally gone" to "turns to be quite hot". There is a thermo control on shower so the temperature should stay still but it is not. I think this boiler I chose should be powerful enough for my small flat, just for shower and maybe another person wash some dishes at the same time? any advise, please?

Hi
It sounds like your boiler is powerful enough but your water pressure is not as it is the pressure that is dropping when in the shower.

The bigger KW output of the combination boiler, the better flow of hot water that can be achieved. But this is obviously capped by the flow of your incoming mains water.
Pressure will also be dictated by your incoming main.
Make one of the showers an electric item! You'll thank me when the boiler breaks down!
