12 kW • 240/208V • Intelligent Whole-House Tankless Performance with Self-Modulating Control
The Stiebel Eltron Tempra 12 Trend (Part #239213) is a precision-engineered whole house electric tankless water heater designed to deliver continuous hot water, exceptional energy efficiency, and consistent temperature control across multiple fixtures. Built for 240/208V applications, this unit is ideal for residential homes, apartments, and light commercial settings where reliable, on-demand hot water is essential.
Advanced Self-Modulating Technology
At the core of the Tempra 12 Trend is microprocessor-controlled self-modulating technology, which automatically adjusts power usage in real time based on flow rate and incoming water temperature. This ensures the system uses only the energy required to maintain the set temperature, delivering optimal efficiency without sacrificing performance.
Unlike conventional tank heaters or basic tankless models, this intelligent system provides smooth, stable temperature control, even during fluctuating demand.
Whole-House Hot Water Without Limits
With a 12 kW output at 240V (9 kW at 208V), the Tempra 12 Trend is designed to supply continuous hot water for multiple low-flow fixtures simultaneously, depending on climate and usage. It eliminates the need for a storage tank, providing endless hot water without recovery time.
High Efficiency with Reduced Operating Costs
Operating at up to 99% efficiency, the Tempra 12 Trend converts nearly all electricity into usable hot water while eliminating standby heat loss. This results in:
- Lower energy consumption
- Reduced utility costs
- Improved overall system efficiency
The result is a cost-effective and environmentally responsible hot water solution.
Digital Temperature Control for Precision
The unit features an intuitive front-facing digital display, allowing users to set and maintain water temperature with precision. The system ensures consistent output across varying flow rates, enhancing user comfort and reliability.
Compact, Space-Saving Design
