    Just been to my brothers new house in Galway. He has a very strange water system. There are no tanks in the attic hot or cold. He as no Hot press and no hot water storage Cylinder. The boiler is fed straight from the mains for hot water and central heating. The hot water is on demand only when he turns on a hot tap in the house the boiler comes on to heat the water he wants and goes off when the tap is turned off. The hot taps are at mains pressure.
    The electric shower and all cold taps in the house are off the mains to. Has any one here ever come across a system like this.

    He has what is called a combination boiler, they are becoming more and more common.

    they have the advantage of almost instant hot water on demand without the losses associated in having a cylinder,
    i.e.if you heat up a cylinder of water and not use then that's wasted energy.

    Disadvantage, flow rate can be quite low so will take a long time to fill a bath and insufficient to run a power shower.

    Mains pressure cold water to all taps etc is now the norm rather than the exception.
