Why Two Pools Generations Produce Two Different Equipment Conversation
Ambler spans housing built across several distinct eras. Ambler Borough has a median construction year of 1954 with 34 percent of homes built before 1940. The pools added to these properties during the 1960s and 1970s are now 50 to 65 years old and carry equipment from the same era. Lower Gwynedd, Maple Glen, and Spring House within the same zip code contain newer homes with newer pools and more current equipment baselines. Applying the same equipment recommendation to both conversations produces numbers that are wrong for at least one of them.
For an Ambler Borough pool from 1972 still running its original single speed pump, the technology gap between what is installed and what current variable speed units deliver is the widest available in our service area for this zip code. The electricity savings on this specific upgrade are the largest because the starting point is the furthest behind. A pump that has been running at one fixed speed regardless of what the pool needs at any given hour, drawing full motor current every hour it runs, produces a meaningful electricity cost every season that a variable speed unit programmed to run at lower speeds during low demand hours substantially reduces.
For a Lower Gwynedd pool installed in 2015 with a builder supplied single speed pump, the starting point is closer to current technology. The savings are real and the upgrade still makes sense, but the payback calculation looks different than it does on the 1972 borough pool. Presenting the same savings figure to both homeowners is the kind of generic approach that a 19002 area homeowner with a median income of $143,600 will see through immediately.
