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-ferous 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.
