Stiebel Eltron Tempra 36 Trend Tankless Water Heater - Whole House

In this review of the Tempra 36 Trend electric tankless water heater, the bottom line is simple: this is a high-capacity, whole-house option for homeowners who want uninterrupted hot water while saving space and energy. The Tempra 36 Trend stands out for its continuous flow performance and intelligent auto-modulation, delivering on-demand hot water without a storage tank. It is best suited to installations that can meet the electrical requirements and for users who value precise temperature control and quiet operation.

Key Features

• Continuous flow: Provides an unlimited supply of hot water on demand so multiple showers can run without the tank running out.
• Auto-modulation: Adjusts energy use to match water demand for improved efficiency and lower operating cost.
• Compact design: Small white enclosure saves floor and wall space and requires no venting, freeing up garage or utility room space.
• Quiet operation: One electronic switch starts the unit and it runs silently, making it suitable for homes where noise matters.
• Digital temperature display: Easy-to-read controls let you set output between 68 and 140F for consistent water temperature.
• Durable heating system: Interior solid copper heating elements provide reliable heat transfer and long-term performance.

Who It's For

The Tempra 36 Trend is aimed at whole-house installations in residences with adequate electrical capacity and homeowners who want on-demand hot water without the footprint of a tank. It works especially well in warm climates where its output can comfortably handle three to four showers, and in cooler climates for up to three.

It is not the best choice for homes that cannot provide the minimum recommended 300 A electrical service or for very small apartments that need a lower kW model. Contractors and DIYers should check the sizing guide and local electrical codes before purchase.

Pros & Cons

Cons
