Effect of Seasonal Incoming Water
Temperature Changes
The required water temperature is achieved by
adjusting the rate of water flow.
The diagram shows the principle involved in
relating temperature rise to flow rate.
The higher the water rate
the lower the temperature
and vice versa.
The temperature of the
water supplied from the
mains can vary
considerably throughout
the year from 5 to 20°C.
This means that in the winter, flow rate will be
less than in the summer to achieve the same
outlet temperature.
In summer the ‘Economy’ (2 x red bars) power
setting may give adequate hot water.
Effect of Other Water Devices on Incoming
Water Supply
Your shower is designed to stabilise
temperature changes caused by water
pressure fluctuations.
These can result from toilets being flushed or
taps being turned on and off.
When this happens your showering temperature
will be held within a controlled band, provided
that the minimum pressure required by the
shower is maintained.
Your shower requires a minimum running
pressure of 100kPa (1.0 bar, 15 psi) at a
minimum flow rate of 8 litres/minute.
( 9 litres/minute for 9.5kW).
At pressures above 100kPa (1.0 bar, 15 psi) at a
minimum flow rate of 8 litres/minute.
( 9 litres/minute for 9.5kW), it will minimise
temperature fluctuations as detailed above.
If the water pressure falls below 100kPa
(1.0 bar, 15 psi) at a minimum flow rate of
8 litres/minute, ( 9 litres/minute for 9.5kW),
it is likely that the pressure switch will turn off
the power to the heating elements, resulting in a
cold shower.

The fitting of Spare Parts must be supervised
