Compare feature to feature with any other electric spa heater, and
you’ll see why Raypak's 'Spa-Pak' sets the standard for performance. All
waterways are corrosion-free copper or bronze, not aluminum, which will
provide a longer, more dependable heater life. The 'Spa-Pak' features a
large size, heavy-duty incoloy heating element that far outlasts
ordinary water heating elements. The 'Spa-Pak' is easy to install with a
compact design that fits into small spaces. Full flow 1-1/2 in. MIP
inlet and outlet connections are conveniently located.
