Caldera Heaters:
Inside Advantages – Hot Tub Heaters
Inside the cabinet, your Caldera® spa's operating components are designed to perform quietly and efficiently, year in and year out.

The exclusive EnergyPro® heating system on the Utopia, and Paradise Series spas helps ensure that you can always enjoy hot tub water that's warm, clean and inviting, with very little effort.

Advanced materials and engineering allow us to offer an unconditional warranty on your spa's unique EnergyPro heater. If it needs replacement for any reason during the first five years of ownership, the materials and labor will be done at no charge to you.

The EnergyPro pump provides the circulation needed for filtration and heating, the jet pumps serve only one purpose. This significantly increases the life expectancy of the jet pumps, compared to those that must perform double duty in most other hot tubs.

Unlike other spa manufacturers' hot tubs, every 230-volt Caldera spa comes standard with a National Electric Code-required GFCI-protected sub-panel, sparing you the expense of an additional electrical panel.

To more effectively clean the water's surface, a telescoping, floating skimmer weir adjusts to high and low water levels.

SPA FROG cartridges provide a simple approach to water care. Just open the SPA FROG cap, insert the mineral and bromine cartridges, close the cap and let SPA FROG do the rest!

A patented system vents the heat produced by the pump motors out of the equipment area to create cooler operating conditions for the spa's equipment, thus extending the life of the hot tub's components. A special sound-dampening Q Chamber® helps ensure whisper-quiet operation.
