How the Alternatives Compare

Stiebel Eltron Tempra 29 Plus 28.8kW Tankless

The Stiebel Eltron Tempra 29 Plus uses 28.8 kW of power, which is slightly less than the Tempra 36 Trend’s 36 kW output. This model measures 16.6 inches wide and weighs 19 pounds, offering a compact footprint for tighter installations. It targets homes with 200-amp electrical service, providing steady hot water without the higher power draw of the 36 kW unit. You get preset controls instead of digital adjustment, simplifying operation. This option suits buyers who value brand reliability and simple functionality over maximum flow rates or smart connectivity features.

WINTEMP 36kW Electric Tankless Water Heater

The WINTEMP 36kW model matches the Stiebel Eltron Tempra 36 Trend’s 36 kW output but adds WiFi connectivity for remote monitoring and control. It weighs 36.1 pounds and measures 21.1 inches tall, making it bulkier than the Stiebel unit. The gray finish and larger dimensions reflect its internal components designed for high-capacity performance. This heater is ideal for large homes with robust electrical systems that need smart features. You gain app integration and safety certification, though you may sacrifice the silent operation and copper heating system found in the Stiebel model.

WINTEMP 36 kW WiFi Tankless Water Heater

The WINTEMP WM36V also delivers 36 kW of power with WiFi capabilities, similar to the other WINTEMP option but with different dimensions. It weighs 38 pounds and stands 19.4 inches tall, offering a slightly more compact profile than the WN36 model. This unit is designed for high-flow homes with strong electrical capacity, providing reliable hot water on demand. You get smart app integration for remote control, which the Stiebel Eltron lacks. The trade-off is a larger physical footprint and potential complexity in installation compared to the straightforward, silent operation of the Stiebel Tempra 36 Trend.

VEVOR 36kW Touchscreen Electric Tankless Water Heater

The VEVOR JN36 provides 36 kW of heating power with a touchscreen interface for precise temperature adjustments. It weighs 34 pounds and measures 5.31 inches deep, offering a slim profile that saves wall space. The black finish and digital controls cater to users who prefer modern aesthetics and easy-to-read displays. This model emphasizes scale resistance, making it suitable for areas with hard water. You gain digital control and a sleek design, but you give up the solid copper heating system and silent operation of the Stiebel Eltron Tempra 36 Trend.

Atmor 36kW 7.03 GPM Tankless Water Heater

The Atmor AT-36N-XTP delivers 36 kW of power with a focus on precise temperature control, achieving up to 7.03 GPM flow. It weighs only 18.2 pounds and measures 23.2 inches long, making it one of the lighter options on this list. The gray finish and compact design suit homes in warm climates or those with limited bathroom counts. This unit is ideal for users who need exact temperature settings without the bulk of larger models. You get precise control and lightweight construction, though you may miss the silent operation and copper heating elements found in the Stiebel Eltron model.

Rheem 36 kW Electric Tankless Water Heater

The Rheem RTEX-36 offers 36 kW of electric heating power with a straightforward design. It weighs 24.4 pounds and features a silver finish, providing a durable build for standard installations. This model is designed for users who prefer manual controls over smart features, simplifying daily operation. It is ideal for those who do not need app-based management or remote monitoring. You gain a reliable, no-frills unit with external temperature control, but you sacrifice the silent operation, copper heating system, and digital display of the Stiebel Eltron Tempra 36 Trend.
