The No-Fault® Heater—No Worries.

Hot Spring leads the industry in advanced heater technology. The heater is typically the most vulnerable component of a hot tub, due to the combination of high heat, water and spa chemicals.

Our unique No-Fault heater's elements and housing are made of titanium for unmatched corrosion resistence. Unlike other spa warranties, your No-Fault heater warranty is valid for five years—regardless of water chemistry.
