Swimming Pool Energy Saving Tips
Please review the following recommendations to help
conserve fuel and minimize the cost of operating your
pool heater without sacrificing comfort.
•
The recommended maximum water temperature is
26 °C (79 °F). Use an accurate pool thermometer. A
difference of 2 °C (3 °F), between 26 °C (79 °F) and
28 °C (82 °F), will use as much as 40% more gas.
• Carefully monitor the water temperature of your pool
in the summertime. You can reduce heater usage due
to warmer air temperatures.
• Find the proper setting on the pool heater temperature
control and use the Set Point Lockout feature to
discourage further adjustments.
• Set the pump time clock to start the pump no earlier
than 6:00 AM. This is the time when nightly heat loss
balances.
• If the pool is only going to be used on weekends,
reduce the heater temperature control setting by 4 or
6 degrees during the week. Reset it to the 26°C
(79°F) level a day or so before you plan to use the
pool.
• During the winter or when on vacation for longer
than a week, shut down the heater by following the
shutdown instructions found in
Section 8.7 and
Figure 16
. and on the inside of the heater.
• Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other
landscaping, cabanas, or fencing.
• The greatest source of heat loss in a swimming pool
is through evaporation. It can accounts for 50% of
pool systems total heat loss. The use of solar
blankets, automatic covers or anything that limits the
air’s access to the surface of the water will help
reduce this heat loss and minimize evaporation.
9.3
Winterizing
In areas where freezing temperatures occur in winter and
the pool or spa will not be used, the pool should be
winterized by a qualified pool service technician:
• Turn off the electrical supply and the main gas supply
to the heater.
•
Remove the heater access panel.
• Turn off gas supply to the heater following the
shut-down instructions.
See
Section 8.7 and Figure 16
.
•
Remove the drain plug from the inlet/outlet header
and completely drain the heater before the first frost.
• Inspect the gasket on the drain plug. Store the drain
plug in a safe place for winter.
•
Cover the exhaust vent grill with plastic so that snow
will not accumulate and freeze on top of the
combustion chamber.
•
Remove and drain the copper tubing (siphon loop)
for the water pressure switch.

Spring Start-up
When winterized, the heater should be reassembled by a
qualified professional technician in the Spring.
•
Reinstall the drain plug.
• Uncover the vent grill.
•
Reattach copper tubing to water pressure switch.
• Make sure power is supplied to the pump.
•
Turn on the filter pump and circulate water through
the heater for 5 minutes. Check for leaks while
circulating.
• Turn on the main gas supply to the heater at the gas
cock outside the heater jacket.
• Turn on the heater according to
Section 8.7 and
Figure 16
.
