Heating & Heat Loss
- Reduce heat loss by using a pool cover. According to the U.S. Department of Energy, savings of 50% – 70% are possible.
- Fencing, hedges, landscaping, and cabanas that shelter your pool from prevailing winds will further reduce heat loss.
- If your pool heater is more than five years old, chances are a new high efficiency gas heater could quickly pay for itself in utility bill savings.
- A pool heat pump can save up to 80% in energy usage compared to a gas heater. Check with your pool professional to see if a heat pump is appropriate for your region.
- If you use your pool only on weekends, reduce your heater or heat pump thermostats settings by eight to ten degrees during the week.
- When leaving for vacation for more than a week, turn off the pool heater or heat pump, including the pilot light. Please use caution in freezing conditions.
- According to the National Swimming Pool Institute and the American Red Cross, the most healthful swimming temperature is 78 degrees. Reducing your heater or heat pump thermostat to maintain a 78 degree or lower temperature will also help conserve energy.
- Install a timer or a control system to automate the hours of operation.
- When reopening your pool, make sure your heater or heat pump is working properly.
- Replace your pool pump with a more energy-efficient model.
- New variable speed pumps with permanent magnet motors and digital controls can save as much as 90% in utility costs compared to one- or two-speed pumps with induction motors.
- If using an energy-efficient one- or two-speed pump, make sure your pump is sized to your pool’s requirements.
- Reduce run time or speed to reduce energy use.
- If using a one-speed pump, reduce filtration run time. In general, water needs to be circulated through the filter once every 24 hours.
- If using a two-speed or variable speed pump, use the lowest speed to appropriately circulate the water. Reducing speed saves more energy than reducing run time.
- Run your pool’s filtration system during off-peak hours when electricity demand is lower, generally between 8 p.m. and 10 a.m. Install a timer or a control system to automate the hours of operation.
- Keep intake grates clear of debris. Clogged drains require the pump to work harder.
