You can spare valuable energy and maintain optimal swimming pool temperatures by using a compact, high efficiency pump and by operating it less often.
In a study of 200 pools by the Green Energy Conservation at The University Of Texas-Arlington, many pool owners saved as much as 80% of their original pumping costs when they applied these energy conservation tactics.
THE SIZING OF THE PUMP
The bigger the pump, the higher your overall pumping and maintenance expenses. Therefore, you want to use the smallest scale pump available for your swimming pool. When selecting the proper size pump, you should always take time to research a pool builders design chart. Using the chart, line up the hydraulic characteristics of the pump to both the piping and the pool’s flow schematics. For an advanced solar heating system, you also need to consider the need to pump the pool’s water to and inside the collector.
OPERATING THE PUMP
Pool pumps often run longer than needed. Constantly circulating your pool’s water keeps the chemicals mixed and removes nasty debris. However, as long the water circulates while chemicals are present, they should typically stay mixed. It’s really not necessary to recirculate the water everyday to take out the debris, most debris can be removed using a vacuum or skimmer. Additionally, more circulation doesn’t necessarily reduce the rapid growth of algae. Alternately, using chemicals in the water and scrubbing the pool walls are considered the best practice.
Reduce your filtration time to 8 hours per day. If the water doesn’t appear clean, increase the timing to half-hour increments until results are achieved. In the Texas study, most people who reduced pumping to less than 3 hours per day were still satisfied with the water’s overall quality. On average, this saved them 65% of their electricity bill for pumping.
You can easily install a programmed timer to handle the pump’s cycling. If debris is an issue, use a timer that can activate the pump for multiple short periods over the course of the day. Running the pump continuously for, say, 4 hours leaves the other 20 hours a day for the pool to collect debris. Short cycles are more effective keep the pool cleaner throughout the day.
Make sure to keep the intake grates free of debris.Drains that are clogged up require the pump to work harder, which expends more energy.Also make sure to backwash your filter appropriately. Backwashing too often wastes water, while not backwashing wastes valuable energy by forcing the pump to work harder.
