Hi Please excuse me if this has been asked 1000 times before, did a search but didn't find anyting on Wiki. There are 4 of us in the house ( bungalow ), shower room and separate bathroom but bath is very seldom used, family use the shower in the morning. I currently have a combi boiler and electric shower. I'm going to re fit the shower room and want to fit a shower with some decent pressure behind it. What is the best method to get good water flow , do I have to fit a hot water tank in my loft ? Thanks. Kenny.
