• 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 Ruud 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 Ruud Electric Spa heater comes standard with 1-1/2" NPT 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 Ruud 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
    Ruud 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 Ruud 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
