What Aging Equipment Costs a Dresher Pool Owner Every Single Season
The financial case for equipment replacement in Dresher is different from the case in newer communities because the pools here have been running longer with equipment that reflects an earlier era of technology. When Upper Dublin Township was expanding in the 1960s and 1970s, the pool industry did not have variable speed motors.
Single-speed pumps running at one fixed output were the only option, and they were installed on every pool built during that period. Many of those pumps were eventually replaced, but a significant number were replaced with the same single-speed technology because it was cheaper at the time. Some of those replacement pumps from the 1990s and early 2000s are still running in Dresher backyards today.
A single-speed pump running eight hours a day from late May through early September on a standard Dresher family pool uses between 1.5 and 2.5 kilowatt-hours per hour depending on its horsepower rating. Over a full swim season of roughly 100 days, that is 1,200 to 2,000 kilowatt-hours just for the pump. At current PECO rates covering most of the 19025 area, that translates to $180 to $300 in electricity for the pump alone each season.
A variable speed pump doing the same filtration job at lower RPM during overnight cycles uses a fraction of that power. The annual savings from switching typically run $400 to $800 on a Dresher family pool, meaning the equipment pays for itself and then keeps paying.
