  • Longer Life
    Because all waterways are corrosion-free copper and bronze - not aluminum. And, SpaPak features large size, heavy duty Incoloy heating elements that lasts far longer than ordinary water heating elements.
  • Troublefree
    Because SpaPak has extra quality and safety built-in - a pressure switch to prevent operation without water flow, a high limit temperature control to prevent overheating and a dependable quality thermostat.
  • Easy to Install
    With a compact design that fits into small spaces. Standard size, full flow 1-1/2" inlet and outlet connections are conveniently located. External current leak protectors are not required.
  • Two Year Limited Warranty
    Against defects in materials and workmanship (see written warranty for details). In addition, every SpaPak is thoroughly tested before shipment.
  • Sizing Guide
The following table shows the heating capability for each model in temperature rise per hour with a given amount of water. For example, the 11kw unit will raise the temperature of 450 gallons of water 10 degrees Fahrenheit in one hour. To determine the gallonage of your spa, multiply the surface area x average depth x 7.5.

Always cover your spa or hot tub when not in use to minimize heat loss and evaporation, and to decrease the time need to heat water.
