Stiebel Eltron Tempra 24 Trend Review: Is This 24kW Electric Tankless Water Heater Right For Your Home?

Hey everyone! I know a lot of people in our group have been asking about ways to upgrade their home’s efficiency and comfort, especially when it comes to hot water. Well, after some extensive research and looking at what our community finds valuable, I wanted to share my thoughts on a product that keeps popping up: the Stiebel Eltron Tankless Water Heater – Tempra 24 Trend.

If you’re tired of running out of hot water, dealing with a bulky tank, or just want to reduce your energy bill, a tankless water heater might be on your radar. And this particular model, made in Germany, promises a lot. Let’s dive in!

Overview

The Stiebel Eltron Tempra 24 Trend is an electric, tankless water heater designed to provide endless hot water on demand. Unlike traditional tank heaters that store and constantly heat a large volume of water, this unit heats water only when you need it, as it flows through the device. This approach is not only incredibly convenient but also significantly more energy-efficient, as there’s no standby heat loss.

What immediately caught my eye, and what many members of our community appreciate, is its “Made in Germany” label. Stiebel Eltron has a long-standing reputation for quality and precision engineering, and the Tempra 24 Trend seems to uphold that standard. It’s a 24kW unit, which means it’s quite powerful and capable of handling hot water demands for a typical household, depending on your climate and water inlet temperature.

I’ve been looking into this for a while, considering how many of us are trying to declutter our utility spaces and cut down on utility bills. The compact, sleek white design of the Tempra 24 Trend is definitely a plus, allowing it to fit into tighter spaces where a traditional tank simply wouldn’t. It’s built to be eco-friendly, focusing on efficient operation to save energy and, by extension, money.

Pros & Cons

As with any product, especially something as significant as a water heater, there are always two sides to the coin. Here’s what I’ve gathered from community discussions and product specifications:

Pros:

• Endless Hot Water: This is arguably the biggest selling point. No more waiting for a tank to refill or worrying about the last person using up all the hot water. It’s truly on-demand.
• Significant Energy Savings: By eliminating standby heat loss, tankless heaters like the Tempra 24 Trend can lead to noticeable reductions in your energy bill over time. This is a huge win for long-term homeowners.
• Space-Saving Design: Its compact size is a game-changer for homes with limited utility space. You can reclaim valuable square footage.
• Precise Temperature Control: The digital display and advanced flow control mean you can set your desired temperature and expect it to be maintained, offering a more comfortable and predictable hot water experience.
• Longer Lifespan: Tankless units generally last longer than traditional tank heaters (often 20+ years vs. 10-15 years), especially with good maintenance, offering better long-term value.
• Reduced Risk of Leaks: Without a large tank full of water, the catastrophic damage from a burst water heater tank is virtually eliminated.
• German Engineering & Quality: The “Made in Germany” aspect provides confidence in its durability, reliability, and precision, which is something our community often values in appliances.

Cons:

• High Electrical Requirements: This is the most crucial consideration for the 24kW model. It requires significant electrical service (typically 240V and multiple dedicated 40-50 amp breakers, depending on the exact configuration). Many older homes, or even some newer ones, may require an electrical panel upgrade or additional wiring, which adds to the initial installation cost.
• Higher Initial Cost: Tankless water heaters, especially high-quality electric ones, have a higher upfront purchase price compared to conventional tank heaters.
• Installation Complexity & Cost: Due to the significant electrical demands, installation often requires a licensed electrician and plumber, making it more complex and expensive than replacing a standard tank heater. It’s definitely not a DIY project for most.
• Flow Rate Limitations (in extreme conditions): While 24kW is powerful, if you live in a very cold climate where incoming water temperatures are extremely low (e.g., 40°F or less) AND you try to run multiple high-demand fixtures (like two showers and a dishwasher) simultaneously, you might experience a slight drop in flow rate or temperature. It’s important to size correctly for your specific needs and climate.
• Potential for Temperature Fluctuations (rare): While its advanced flow control is excellent, in rare cases of unstable incoming voltage or highly fluctuating water pressure, some users might experience minor temperature shifts, though this is far less common with premium models like the Tempra Trend.

Who Is It For?

Based on its features and our community’s needs, the Stiebel Eltron Tempra 24 Trend is an excellent choice for:

• Homeowners Seeking Energy Efficiency: If reducing your energy consumption and lowering utility bills is a priority, the tankless design is a major advantage.
• Those with Limited Space: If your utility closet is cramped or you want to free up space in your basement or garage, its compact footprint is ideal.
• Families Tired of Running Out of Hot Water: Large families or households with multiple bathrooms will greatly appreciate the endless supply of hot water, especially during peak usage times.
• People Looking for Long-Term Value and Reliability: The German engineering and longer lifespan mean this is an investment that should pay off over many years, reducing the frequency of replacement.
• New Construction or Major Renovations: If you’re building a new home or undertaking a significant renovation, it’s easier to plan for the electrical upgrades required for a unit like this.
• Environmentally Conscious Individuals: Its eco-friendly, on-demand heating aligns well with a sustainable lifestyle.

However, it might be less suitable for those on a very tight initial budget or in homes with severely outdated electrical systems that would make the upgrade prohibitively expensive. Always consult with a qualified electrician to assess your home’s electrical capacity before purchasing.

FAQ

Here are some common questions our group members have asked about electric tankless water heaters like the Tempra 24 Trend:

Q1: What are the specific electrical requirements for the Tempra 24 Trend?

A: The Tempra 24 Trend is a 24kW unit, meaning it typically requires three dedicated 40-amp double-pole breakers (for a total of 120 amps at 240V). This is a substantial electrical load. It’s crucial to have a qualified electrician assess your home’s electrical panel and wiring to ensure it can support this demand, or to determine if an upgrade is necessary.

Q2: How much hot water can it provide? Can it handle multiple showers at once?

A: The amount of hot water (flow rate) it can provide depends heavily on the incoming water temperature and your desired output temperature. In warmer climates or with typical incoming water temperatures (e.g., 60-70°F), a 24kW unit can often handle 2-3 showers simultaneously without issue. In colder climates with very low incoming water temperatures (e.g., 40°F), it might comfortably handle 1-2 showers. Stiebel Eltron provides sizing guides that are very helpful for making sure it meets your specific household needs.

Q3: Is the installation a DIY project?

A: No, absolutely not. Due to the high electrical demands and the need for proper plumbing connections, installation of the Tempra 24 Trend should always be performed by a licensed and qualified electrician and plumber. Incorrect installation can be dangerous and void your warranty.

Q4: How does it save energy compared to a traditional tank heater?

A: Traditional tank heaters constantly heat and reheat a large tank of water, even when you’re not using it. This is called “standby heat loss” and accounts for a significant portion of their energy consumption. The Tempra 24 Trend, being tankless, only activates and consumes energy when you turn on a hot water tap, heating water instantly. This elimination of standby loss is the primary way it saves energy.

Q5: What kind of maintenance does it require?

A: Tankless water heaters generally require less maintenance than tank units, but they do benefit from periodic flushing to remove mineral buildup, especially in areas with hard water. This helps maintain efficiency and prolong lifespan. The frequency depends on your water quality, but typically every 1-2 years is recommended. Stiebel Eltron provides guidelines for this.

Final Verdict

Alright, so after digging into the Stiebel Eltron Tempra 24 Trend, I’m genuinely impressed. For those in our community looking for a modern, efficient, and reliable hot water solution, this unit checks a lot of boxes. The promise of endless hot water, significant energy savings, and a space-saving design are incredibly appealing, especially coming from a brand known for German engineering.

However, it’s crucial to go into this with open eyes, particularly regarding the electrical requirements. The upfront cost for the unit itself and potential electrical panel upgrades can be a barrier for some. But if your home’s electrical system can handle it, or if you’re planning an upgrade anyway, the long-term benefits in terms of comfort, energy efficiency, and durability make it a very strong contender.

Our community values products that perform well and offer real solutions, and the Tempra 24 Trend definitely falls into that category for the right household. It’s an investment, but one that promises to deliver consistent, on-demand hot water for years to come, all while helping to reduce your carbon footprint and energy bills. If you’re serious about upgrading your home’s hot water system, this is definitely one to consider seriously.
