This recent spurt of steamy weather got me thinking about taking a nice
cold shower, but it seems our electric shower has other plans. With the

water through a constantly 'on' heater who's power is crudely controlled
by the 'high/low power' buttons, and the temperature of the water is
increased by reducing the pressure with an adjustable valve thus causing
it to flow through the heater more slowly allowing it to heat up for
If so, would it even be possible to get a cold or cool shower with no
