Energy-Saving Pool Equipment Choices

While the pump is usually the center of conversations about pool equipment energy savings, other equipment choices also play important roles.

Filter types, for example, have an impact on energy consumption because they place different levels of resistance on the system. Resistance is related to energy efficiency because of its impact on flow. Of the three types of filters (cartridge, DE and sand), cartridge filtration offers the least (i.e., most favorable) resistance to flow. This is partially because cartridge filters do not require a valve, while filters that are routinely backwashed do need them. Multiport valves create so much resistance to flow that California's Title 24 has banned 1.5-inch multiport valves. (Newer backwash valves have been designed to add less resistance to the system.) On a related note, backwashing consumes water, so using a filter that does not require backwashing conserves water and the chemicals in that water.
