When we talk about the most effective way to reduce a pool’s energy consumption, the focus typically turns to the pump, because it consumes more energy than any other piece of pool equipment, outside of a heater or heat pump. Did you know that a variable speed pump, more communally known as a VSP can reduce the energy costs of running a swimming pool by up to 90%
Historically, pool pumps are equipped with induction motors that run at only one speed and use more energy than is required to circulate pool water. That is because a pump that can run at only one speed must be powerful enough to do the pump’s most demanding job (e.g., running a waterfall or pool cleaner). However, it takes far less power to simply keep water filtered—a difference single-speed pumps cannot address. Also, in the early stages of development, VSP pumps were 240 Volt only and that sometimes became an issue for a replacement of an existing pump that did not have that higher voltage available at the equipment pad. Today, 120 Volt VSP pumps that can develop 1.5 HP are available for new installations or retrofit older single speed models.
