Overview

The 8-year old Lochinvar CopperFin pool heating system failed in January 2017. Initially, the repairs were focused on replacement of the failed heat exchanger. A replacement heat exchanger was procured, and crews arrived to perform the replacement. When the heater was opened up to replace the heat exchanger, the sheet metal housing was found to be compromised. The entire heater required replacement.

The heater replacement consists of an upgrade to an indirect heat exchange system. The Lochinvar Aquas XPN1502 natural gas indirect swimming pool heating system comes factory-ready on a skid-mount, with a 1.5 million Btu boiler with Smart System touch screen controls, 2 million Btu cupro-nickel heat exchanger with bronze tubes and shell, CPVC pool water connections and 2 primary boiler water circulating pumps.

This upgrade represents an improved water heating efficiency from 89% to 97%, resulting in decreased gas consumption. Annual maintenance costs are also decreased due to the indirect nature of heating: the Lochinvar Aquas is an indirect fired heat exchanger system; therefore pool water does not circulate directly through the boiler, eliminating costly repairs and component replacements due to water chemistry fluctuations. In addition, due to the indirect heating system, the service life of the Lochinvar Aquas XPN1502 is twice the life expectancy of a direct-fired pool water heater.
