10.2 Swimming Pool Energy Saving Tips
Please review the following recommendations to help conserve fuel and minimize the cost of operating your pool
heater without sacricing comfort.
• The American Red Cross
®
recommends a maximum water temperature of 78°F (26°C). Use an accurate pool
thermometer. A difference of 4°F (2°C), between 78°F and 82°F (26°C and 28°C), 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 8 or 10 degrees
during the week. Reset it to the 78°F (26°C) 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 8.6 and Figure 22 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 account 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.
10.3 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 qualied 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 8.6 and Figure 22.
• Remove the drain plug from the inlet/outlet header and completely drain the heater before the rst frost. See
Section 5.5.1 step “a”
• 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.
