Quick Function Test
Observe the main electricity meter when the heater is on (i.e.: red light
‘On’) and then observe it again when the heater is in the standby mode
(i.e. amber light ‘On’) The test should show that the meter is recording
more electricity being used by the heater when the red light is ‘On’. It
is impossible for an electric heater to waste energy, if it is drawing
power then that power will be turned into heat that will be transferred
to the water.
Accurate Function Test
If a more accurate test is required to confirm that your heater is delivering
the specified heat output, two electricity meter readings will need to be
taken from the properties main electricity meter, at one hourly intervals
(i.e. take one-meter reading and then a second reading exactly one hour
later) By subtracting the first reading from the second reading the number
of units (kilo watts kW) consumed can be calculated. Note that your
heater is also rated in kW hours.
The pool pump and heater will need to be running continuously during
the test (i.e.: with the heater red light ’On’) To avoid inaccurate results
when performing this test, it is important to refrain from using other high
current consuming appliances in the property (such as tumble dryer,
showers, cookers etc.). A large domestic pool pump of 1 horsepower will
draw less than 1kW in a one-hour period. The conclusion of the test
should prove that for example a 6kW heater and a ½ horsepower pump
will draw between 6.3- kW ~ 6.5- kW in one hour.
