NEW Stiebel Eltron DHX-12/15 Tankless Electric Water Heater, 240V, 14.400 Watts
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
Built for the Long Haul
The DHX-12/15 is manufactured in Germany and assembled in the USA by Stiebel Eltron — the global pioneer of electric tankless water heating with nearly 100 years of engineering heritage. It carries:
- ETL Listed — Conforms to UL Std. 499 / CAN/CSA Std. C22.2 No. 64
- WQA Certified — NSF/ANSI/CAN 372 lead-free compliant
- ISO 9001 Certified manufacturing
- 5-year warranty against leakage / 1-year warranty against defects in workmanship and materials
Ideal Applications
- Residential bathrooms, cabins, and cottages
- Single or dual-shower setups in warm climates
- Sink + shower combinations in moderate climates
- Any point-of-use installation where space, efficiency, and reliability matter
No venting required. Sleek European design. Space-saving installation close to the point of use.
Size It Right
Proper sizing is critical for optimal performance. The DHX-12/15 can support two simultaneous showers in warm-groundwater regions, or one shower plus one sink in other U.S. markets. Contact Miami Water Heater’s support team at 305.633.2656 for personalized sizing recommendations.
