Operating Instructions
The heater will only switch ‘On’ (red heater on light illuminated) when the
following criteria are met i.e.:
• Water circulating pump is ‘On’ delivering in excess of the minimum flow
rate (see flow requirement information - page 5)
• Required temperature is set to a higher value than that of the water (via
the digital thermostat - refer to page 6)
Q:
How long will it take to heat my pool?
A:
Assuming no heat losses
, and a heater sized in the ratio 1.5-kW
per 1,000 UK gallons of water (4,545-litres): it will take 2 days of
continuous running to raise the temperature of a pool from tap
temperature to swimming temperature. Heat loss will slow the heating
process, particularly during periods of cold weather, hence the higher
the water temperature is to be maintained above average ambient air
temperature, the slower the heating process will become.
The only influencing factors are the level of insulation and the location
of the pool with regard to wind shelter.
Useful advice:
To reduce running costs and speed up the heating process; Insulate
the pool wherever possible. A floating solar cover is an essential minimum to retain
heat.
Quick Function Test
Observe the main electricity meter when the heater is on (ie: red heater on light
illuminated) and then observe it again when the heater is in the standby mode
(ie: red heater on light not illuminated) 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.
