Why Oreland, PA's Old Pool Motors Have Been Overpaying PECO Rates
The electricity savings case for a variable speed pump upgrade is not the same at every pool. It depends directly on what the existing motor is, how many hours per day it runs, and how many technology generations separate it from current variable speed units. On an Oreland, PA pool from 1958 still running its original single speed motor, every one of those factors produces the widest savings gap available in our service area.
Original single speed motors from the late 1950s and early 1960s were designed around the technology and efficiency standards of that era. Efficiency requirements for residential pool equipment did not exist in any meaningful form at the time these motors were installed. Each successive generation of pump design after those originals introduced improvements that made the previous generation progressively more expensive to run by comparison. A pool from 1958 in Oreland, PA that has not had its pump upgraded since installation has been on the losing side of that efficiency progression for the entire period between then and now.
At current PECO rates, an original 1960s single speed motor running at full output for eight to ten hours per day across a standard swim season uses between $350 and $550 in electricity. A current variable speed motor programmed to run slow overnight filtration cycles and higher speed daytime circulation uses between $60 and $120 at those same rates. The $350 to $430 annual saving at Oreland, PA is the direct result of ending a 60 year pattern of paying full motor output rates for filtration that does not require full motor output for most of the hours the pump runs. The assessment visit is where we calculate that saving specifically for the motor actually running on the pool rather than using a generic range.
