Residential pool pumps are used to circulate and filter swimming pool water in order to maintain clarity and sanitation.
Five states (Arizona, Connecticut, Florida, New York, and Washington) have adopted swimming pool pump standards based on standards which California implemented starting in 2006. The California standards included the following requirements:
- Motors shall not be split-phase or capacitor start-induction run type motors, except:
a. the low-speed section of two-speed motors may be capacitor start-induction run type, and;
b. 48-frame motors designed for use with above-ground pools are exempt from this requirement.
- Motors with a total horsepower capacity of 1 or more shall have the capability of operating at two or more speeds with a low speed having a rotation rate that is no more than one-half of the motor’s maximum rotation rate and shall be operated with a pump control with the capability of operating the pump at two or more speeds.
- Residential pool pump motor controls that are sold for use with a two- or more speed motor shall have the capability of operating the pool pump at least at two speeds and shall have a default circulation speed setting no more than one-half of the motor’s maximum rotation rate. Any high speed override capability shall be for a temporary period not to exceed one 24-hour cycle without resetting to the default settings.
DOE is not currently required to set standards for these products.
In warm-weather states where pools are used for many months of the year, efficiency standards have great potential for energy savings and are thus very cost-effective. In warmer climates, pool pumps can be among the largest consumers of electricity in the residential sector. For example, in California, pool pumps consume on average 2,600 kWh per year, an amount equal to 44% of the annual electricity consumption of a typical California household. The standard would cut electricity use by at least about 40% on average, or by about 1,040 kWh per year in the California example. The combination of two-speed pumps and controls is estimated to cost about $580. For consumers using a compliant product in warm-weather states (such as Arizona, Florida or Texas), the estimated savings relative to a basic unit are over 1200kWh/year with a payback period of approximately 3.5 years This analysis does not include peak demand reduction benefits, which can be significant. This standard may also be of particular interest in high-growth states where swimming pools are common with high-end new housing. Based on input from industry experts, ASAP estimates that about 2% of products sold outside of California met this standard in 2009.
