HOW YOUR WATER HEATER WORKS
A VERY SAFE SYSTEM
Water is stored in a copper tank containing a copper heat exchange coil. Water in
the tank is heated by an electric heating element. As cold water passes through
the heat exchange coil it is heated by the transfer of heat from the hot water in
the tank to the cold water in the coil. The mains pressure water in the coil, now
hot, is then delivered to taps in the home.
Water delivered from a heat exchange system gradually reduces in
temperature during the course of prolonged draw off and you will find the
need to make small adjustment to the hot and cold taps or your lever mixer to
maintain an even flow at the temperature which suits you. After a short time
this will become an automatic and unconscious response. This does not mean
you are running out of hot water.
MAINS PRESSURE
The internal copper coil heat exchanger is designed to operate at mains pressure
for connection to the mains water supply. If the mains supply pressure in your
area exceeds that shown on Page 11 ‘Water Pressure’, a pressure limiting valve
must be fitted.
ELECTRICAL SUPPLY
•
Continuous electricity supply.
This type of supply is required where the unit is operating at maximum
capacity.
•
Off peak or controlled electricity supply.
This type of connection will only allow heating to occur during certain set
hours and requires larger capacity units. A volume of water sufficient for the
day’s total use is heated and stored. This type of supply is more economical.
THERMOSTAT
The thermostat automatically controls the electricity supply to the heating
element, maintaining a constant temperature. The thermostat is mounted inside
the junction box cover of the water heaters.
Do not switch off the water heater when it is not in use, except for extended
periods. The thermostat is fully automatic and only uses power when heating is
required.
