Paul,
Why is it that people in the UK prefer to use an Instant Water heater rather than the normal Stored Hot Water Cylinder?.
The savings in power must justify using a stored water cylinder?.
I've installed a few of the Instant Hot water units here (in a Gym shower room) and thought maybe it was because they couldn't get the required fall to get good enough water pressure.
The units I installed here were 7kW each, spread over 3 phases, but the question still lies.
