I guess you mean a Combination Boiler: no cold water tank in loft; no
hot
water storage tank; hot water in taps "on demand".

Although I love my Combination Boiler for the hot water on demand and
low
overall running cost, when they go wrong it is usually more expensive than
a
standard system so if you have a family, a "traditional" system
with timed
water heating (with possible immersion heater supplement) and hot/cold
water
tanks might work out cheaper in the long run.

With a combination boiler, it is usual to use either a simple mixer
shower
or an elecric shower with cold water input only to take advantage of
mains
pressure to provide the power which are usually as good as/better than a
lot
of "power showers". If you do need more power then I think you
need to add a
cold water tank and use a cold feed only for the pump to get the power.
Most
shower systems will indicate in their requirements if they are
compatible
with a combination boiler.

As for X10, if you merely wish to replace the usual master power swtch,
you
just need a module with an appropriate rating to do so. How you turn
the
system on and off is of course open to debate since it could be driven
by
motion sensor, local control, timers etc. It is somthing on my to do
list
and the activation system is the main reason I have yet to implement
it.
