Energysaving Tips Cut Summer Pool Costs

As summer temperatures rise, swimming pools become essential retreats for cooling off. However, the electricity bills from continuously running pool pumps can quickly dampen the enjoyment. Pool pumps, while crucial for maintaining water quality, are significant energy consumers. Implementing smart strategies can help reduce energy consumption without compromising water cleanliness.

Choosing an appropriately sized pump is the first and most critical step in energy conservation. Contrary to common belief, larger pumps don't necessarily provide better filtration and often lead to unnecessary energy expenditure.

Determining pool capacity is fundamental to selecting the right pump:

• Rectangular pools: Length × Width × Average Depth
• Circular pools: π × (Radius)² × Average Depth (π ≈ 3.14)
• Irregular pools: Divide into regular shapes and sum their volumes

For most residential pools, a 0.75 horsepower (HP) or smaller pump typically suffices. Oversized pumps increase both initial costs and ongoing electricity consumption.

Reducing hydraulic resistance through plumbing improvements allows for smaller, more efficient pumps:

• Install larger filters to increase surface area
• Use wider diameter pipes to minimize friction
• Reduce unnecessary bends and connections
• Select smooth pipe materials

ENERGY STAR certified pumps incorporate advanced motor technology and hydraulic designs that significantly reduce energy use. While these models may have higher upfront costs, the long-term savings in electricity bills often justify the investment. Some regions even offer rebates for ENERGY STAR certified pool equipment.

Optimizing run times is another key strategy for energy conservation. Continuous operation is typically unnecessary for maintaining water quality.

Most pools only require 6 hours or less of daily filtration. The filtration system primarily circulates water and distributes chemicals, with extended operation providing minimal additional benefit. Adjust run times based on actual pool usage and water conditions.

Programmable timers allow for multiple shorter filtration cycles throughout the day rather than continuous operation. This approach maintains water quality while minimizing energy use. Both mechanical and digital timers are available, with digital models offering greater precision and flexibility.

Proper maintenance reduces pump workload and extends equipment life, contributing to energy savings.

Regularly remove debris from skimmer baskets and pump intakes. Blockages force the pump to work harder, increasing energy consumption.

Frequent skimming and vacuuming reduce the filtration system's workload. Less debris in the water means the pump doesn't need to work as hard to maintain clarity.

Filter maintenance is crucial. Backwash sand or DE filters when the pressure gauge reads 8-10 psi above normal operating pressure. Excessive backwashing wastes water, while insufficient cleaning strains the pump.

Implementing these strategies—proper pump selection, optimized operation, and regular maintenance—can significantly reduce pool-related energy costs. With careful planning and consistent practices, pool owners can enjoy refreshing swims without the shock of excessive electricity bills.
