BATH TUB HEATERS ARE AN AID IN MAINTAINING WATER TEMPERATURE AFTER HOT WATER IS IN THE TUB. NOT AS A HEATER FOR COLD WATER IN THE TUB.
The PH101-10UP bath heater is a universal, in-line heater manufactured by Hydro-Quip. Because it's a standard and versatile part designed to fit "most jetted tubs and whirlpool baths," it is not typically tied to a specific major hot tub brand but rather used as a component or a replacement part across many different systems.
This part is primarily used in jetted bathtubs and whirlpool baths rather than large portable outdoor spas, as it is a 1.0 kW, 120V low-flow heater.
While Hydro-Quip supplies equipment to many OEMs and the aftermarket, specific manufacturers who may have used this part include:
Jacuzzi: The PH101-10UP is listed as a potential replacement for certain Jacuzzi® bathtub heater models.
American Standard: The product is sold as a compatible or similar replacement for certain E-Z-Install whirlpool heaters.
Various Whirlpool Bath Manufacturers: Due to its universal and compact design, it is used by numerous other brands of jetted bathtubs, often as a non-branded original equipment manufacturer (OEM) part.
To confirm if this part is in your specific unit, it's best to check the manufacturer's manual for your bath or look for a label on the existing heater unit itself.
