Why Glenside's Oldest Pool Stock Produces Widest Technology Gap
The electricity savings a variable speed pump upgrade produces are real, but they are not the same for every pool. They depend directly on what the existing pump is and how many technology generations separate it from current variable speed units. A pool whose pump was replaced in 2015 with a single speed unit is starting from a narrow gap with correspondingly modest savings. A pool whose pump has been running continuously since 1963 is starting from the widest possible gap available in our service area.
Understanding why requires a brief honest account of what happened to pool pump technology between the early 1960s and 2026. The original single speed pumps of the 1950s and 1960s used basic motor designs with no electronic controls, no ability to vary output, and no efficiency standards to meet because energy efficiency requirements did not yet exist for residential pool equipment. Each subsequent technology generation after those originals introduced meaningful efficiency improvements over the previous one. The current electronically controlled variable speed units represent the cumulative result of every one of those generational improvements stacked on top of each other. A Glenside pool from 1963 sits at the far end of that entire progression.
The filter side of the same story is shaped by Glenside’s specific organic environment. Pools throughout the 19038 area face the heaviest organic input of any community we service, from generations old residential canopy at one of the highest population densities of any older suburb near Philadelphia.
