I live in a tiny ex-council 2.5 bed flat that barely gets cold enough to turn the heating on (we haven't had it on yet) and 1 bathroom. I don't think we need to worry too much about two showers at the same time, when this boiler was working at 100%, the hot water pressure and consistency of temperature delivered was satisfactory so I'm happy to replace like-for-like in terms of kW and L/minute.
