BATH TUB HEATERS ARE A AID IN MAINTAINING WATER TEMPERATURE AFTER HOT WATER IS IN THE TUB. NOT AS A HEATER FOR COLD WATER IN THE TUB.
The PH101-15UP bath heater is a universal, in-line heater primarily used in jetted bathtubs and whirlpool baths, rather than large outdoor hot tubs. It is a 1.5 kW, 120V low-flow heater manufactured by Hydro-Quip.
Because it is a highly versatile and compact aftermarket or OEM part, it is used by numerous manufacturers, but often listed as a replacement for specific models:
Jacuzzi: The PH101-15UP is a direct replacement for several older or specific Jacuzzi® bathtub heater models, including part numbers like 90-221105P and C3B5340-E002JUP.
American Standard: The product is sold as a compatible or similar replacement for some of their E-Z-Install whirlpool heaters.
Hydropool: The heater assembly is available as a specific part for their jetted bath lines.
Vita Spas: Vita Spas is a brand that utilizes Hydro-Quip components and parts in some of their systems.
Other Manufacturers: Due to its "universal" design, it can be used in jetted tubs from many other manufacturers who use standard 1-inch or 1.5-inch plumbing connections, as noted by part suppliers who market it as a fit for "most jetted tubs".
The universal nature of this heater means it's a common, non-exclusive part across the jetted bath industry.
