19.2 kW • 240/208V • High-Capacity Whole-House Tankless Performance with Intelligent Control
The Stiebel Eltron Tempra 20 Trend (Part #239215) is a high-output, precision-engineered whole house electric tankless water heater designed to deliver continuous hot water, exceptional efficiency, and consistent temperature control for larger homes and light commercial applications. Built for 240/208V systems, this model provides the capacity and performance needed for multiple simultaneous hot water demands without the inefficiencies of traditional tank heaters.
Advanced Self-Modulating Technology
At the core of the Tempra 20 Trend is microprocessor-controlled self-modulating technology, which automatically adjusts power consumption based on real-time hot water demand. This ensures the unit uses only the energy required to maintain the set temperature, improving efficiency while delivering stable performance.
Unlike basic tankless systems, this technology maintains consistent outlet temperatures even when flow rates change, eliminating hot and cold fluctuations.
High-Capacity Output for Demanding Applications
With a maximum output of 19.2 kW at 240V (14.4 kW at 208V), the Tempra 20 Trend is engineered to support multiple fixtures operating simultaneously, depending on climate and installation conditions. Its higher capacity allows for:
- Greater temperature rise in colder climates
- Increased flow capability across multiple outlets
- Reliable performance during peak usage
This ensures continuous, on-demand hot water without recovery time, making it a true whole-house solution.
Energy Efficiency Without Standby Loss
The Tempra 20 Trend operates at up to 99% efficiency, converting nearly all electrical energy into usable hot water. By eliminating standby heat loss, it delivers:
- Reduced energy consumption
- Lower operating costs
- Improved system efficiency
This makes it a cost-effective and environmentally responsible alternative to traditional storage water heaters.
Precision Digital Temperature Control
The unit features an easy-to-use digital temperature display, allowing precise adjustment of water temperature. The system maintains consistent output regardless of demand fluctuations, ensuring reliable comfort and performance.
Compact, Space-Saving Design
Despite its high output, the Tempra 20 Trend features a compact, wall-mounted design that requires no venting. This allows flexible installation in utility rooms, closets, or tight mechanical spaces while freeing up valuable floor space.
