Whole-House Power in a Point-of-Use Package

The DHX-12/15 is a game-changing electric tankless water heater engineered for residents of warm-climate states like Florida, Texas, and Southern California. Capable of delivering up to 3 gallons per minute (GPM), it can simultaneously serve a bathroom sink and up to two showers — delivering unmatched versatility in an ultra-compact footprint.

Exclusive Technology. Unmatched Comfort

 With the proprietary Direct Coil™ heating system, the DHX-12/15 delivers:

• Self-cleaning limescale resistance — reducing maintenance needs and extending product life
• Rapid heat-up and response — so you're never waiting for hot water
• Electronic self-modulation — using only the electricity required, maximizing energy efficiency at 99%

More Hot Water. Same 60-Amp Breaker

The DHX-12/15 is engineered to do more with the same electrical infrastructure. The same 60-amp breaker that powers a smaller 13 kW competitor unit can run the higher-kW DHX-12/15 — meaning more hot water to more fixtures, at no additional electrical cost.

Smart Display. Total Control.

The DHX-12/15 features the largest digital backlit display in its class, putting full control at your fingertips:

• Preset temperature memory buttons for quick adjustments
• Real-time capacity monitoring
• Built-in cost savings calculator
• User-selectable scald guard for added safety
• Front-panel control lock-out for peace of mind
