One of its standout features is the ability to provide on-demand hot water, which means no more unexpected cold showers. With a flow rate of up to 9.5 gallons per minute, it can serve an entire household, making it ideal for families or homes with high water usage needs.
In terms of energy efficiency, this unit is a strong contender. Its sleek design not only saves space but also incorporates auto-modulation technology to minimize energy use when hot water is not needed. This makes it a great eco-friendly choice for environmentally conscious consumers. The silent operation further enhances its appeal, as it won't disrupt your home environment while in use.
The Tempra 29 Trend requires a significant electrical service of at least 200 amps, which may necessitate an upgrade to your home’s electrical system if it currently does not meet this requirement. Additionally, while it has a good warranty (7 years for leakage and 3 years for parts), some users may still worry about the initial installation costs and the need for professional setup. The digital temperature display is a convenient feature, allowing users to monitor their water temperature easily. It's compact at 16.63 inches wide and 14.5 inches high, making it suitable for various installation spaces. Potential buyers should verify that their plumbing can support a tankless unit effectively.

The Stiebel Eltron Tempra 24 Plus is a well-designed electric tankless water heater that’s great for providing continuous hot water throughout a home. Thanks to its Advanced Flow Control technology, it keeps water temperature steady even if multiple taps are in use, which means fewer interruptions during showers. This model has a strong 24kW power rating and requires a 240V, 150A electrical service, so it's important to ensure your home's wiring can support it before installation.
Its temperature range (68° to 140°F) can be adjusted easily with a digital display, and it even offers preset temperature memory, making it user-friendly. The compact size and wall-mounted design save space and eliminate the need for venting, which helps in smaller homes or apartments. It's also energy efficient with auto-modulation that adjusts power based on demand, potentially lowering electricity bills, and it includes a monitor to track savings.
