Stiebel Eltron Tempra 24 Plus Tankless Water Heater Review Energy Efficient Performance

Description

Highlights of the Stiebel Eltron Tempra 24 Plus Tankless Water Heater

Testing out the Stiebel Eltron Tempra 24 Plus was quite an experience. This German-engineered marvel boasts a compact, sleek white design that easily fits on a wall without demanding much space. The unit delivers continuous flow hot water using patented advanced flow control technology, which automatically adjusts water flow to maintain a steady temperature. This means no more cold water shocks during showers, even when multiple taps are running. The digital LED display and preset temperature memory buttons make controlling the water temperature straightforward and user-friendly. My family appreciated the consistent warmth, especially during busy mornings when everyone needs a hot shower without interruptions.

• Continuous flow with automatic temperature regulation
• Compact and space-saving design
• User-friendly LED digital control panel

Drawbacks to Consider Before Buying

While the performance is impressive, this tankless water heater isn’t without its quirks. Installation requires a fairly heavy-duty electrical setup, specifically a minimum recommended electric service of 150 amps at 240 volts, which might demand an upgrade of your home’s electrical panel if it’s outdated. This could add unexpected costs. The unit also weighs about 21 pounds, so mounting it securely on the wall requires some effort. Although the heater provides hot water for up to two simultaneous showers in warm climates, it might struggle a bit during colder months or in larger households demanding higher flow rates. Another thing I noticed is the lack of a battery backup, which means power outages will leave you without hot water unless you have an alternative heating source.

• Requires 150 A electrical service, possibly needing panel upgrades
• Heavy unit at 21 pounds, mounting requires sturdy support
• Limited simultaneous hot water output in colder climates
• No battery backup for power interruptions

Performance and Features in Everyday Use

The self-modulating technology inside this water heater is a real game-changer. It adjusts the electrical input based on the demand, which means it only uses as much energy as necessary to heat the water. This feature translates into energy savings of up to 34% compared to traditional tank heaters. The solid copper heating element feels robust and durable, and I noticed the water temperature remains stable even when multiple fixtures are in use. The temperature range can be set from 68°F to 140°F, with a safety limit option at 109°F to prevent scalding—ideal for households with kids or elderly residents. Noise levels are minimal; the heater operates almost silently, which is a nice bonus.

Installation and User Experience

Installing this heater was a bit of a project. Its wall-mounted design means you’ll need some DIY skills or a professional plumber and electrician to get it set up correctly. The unit does not require venting, which simplifies things, but the electrical requirements are strict. Once installed, operation is surprisingly easy. The digital temperature display provides clear feedback, and the preset buttons allow for quick switching between favorite temperature settings. My spouse found this especially convenient after adjusting the water for the kids’ baths. The energy savings monitor is a nice touch, showing how much you’re saving, which adds to the satisfaction of using an eco-friendly product.

Value Assessment: Is This Worth the Investment?

Considering its advanced features and energy efficiency, this tankless water heater offers strong value for the price. It’s positioned higher than many basic models but justifies this with its patented temperature control, durable build, and consistent performance. If your household demands steady, on-demand hot water and you’re prepared for the upfront installation effort, this heater could pay off in reduced utility bills and endless comfort. Comparing it to traditional storage tanks, the lack of standby heat loss alone makes it a smart spending choice in the long run. However, if your home’s electrical system isn’t ready for the power draw, the initial setup costs might be a drawback.

Product Comparisons with Market Rivals

Looking at competitors, this tankless water heater stands out for its German engineering and patented flow control technology. Brands like Rinnai and EcoSmart offer similar tankless solutions, but the Tempra 24 Plus feels more refined in terms of temperature stability and quiet operation. Some rivals provide more compact or lighter units, which might appeal to those with space constraints. However, many lack the energy-saving auto-modulation feature that makes this model efficient. In contrast with some gas-powered models, the electric design avoids venting issues and emissions but requires a solid electrical infrastructure. Overall, this heater excels in eco-friendliness and temperature precision, although it may fall short if instant high volume hot water is needed for a very large household.
