Technical Features - All Models

  • Brass Headers: Brass headers prevent rust stains from harming your pool or spa's surface, giving you years of trouble-free swimming pleasure. They also allow for a corrosion free connection to your spa plumbing, making any future servicing a snap.
  • Copper Water Vessel: The Rheem Electric Spa heater has a completely non-ferrous waterway. The cast brass headers are connected with an all copper water tank. This ensures that the spa water only comes in contact with a rust free environment. This helps keeps your spa rust stain free.
  • 1 1/2" Water Connections: Every Rheem Electric Spa heater comes standard with 1 1/2" NTP male connections to make your installation secure and effortless. No other special connections are required, such as current collectors or heat sinks.
  • Heating Element: The heart of any electric heater is the heating element. The Rheem Electric Spa heater comes with a robust, incoloy sheathed heating element. The top of the element is 3/16" stainless steel, again, ensuring a rust free environment.
  • Contactor: Rheem Electric Spa heaters use commercial grade components. Take one look at the heavy duty power contactor and you know this heater is built to last.
  • Safety: Inside every Rheem Electric Spa heater is a built-in device to prevent overheating. In the event the heater is energized when the water flow is insufficient, a resetable high limit will prevent the heater from operating in an unsafe condition.
  • 240v Operation: Both of the Rheem Electric Spa heater's operate with 240v single phase power. The model 552 draws about 23 amps @ 240v and the model 1102 draws about 46 amps @ 240v.
  • Energy-Efficient: Energy-smart Rheem heaters consistently achieve the highest efficiency ratings. They exceed all federal and state standards.

  • ISO 9001: We are proud to be an ISO 9001 registered manufacturing plant. It's one more reason why Rheem is number one in the heater industry today.
  • End-of-Line Test: Every Rheem electric spa heater is test-fired before it is put in the carton. This ensures that your heater will work right out of the box and continue to give you years of trouble-free operation.
  • UL Listed: The Rheem electric spa heaters are listed with UL and cUL.
