Stiebel Eltron Tempra 29 Trend Tankless Water Heater Review: Endless Hot Water & Energy Savings?

Hey everyone! I know a lot of people in our group have been asking about tankless water heaters, especially with energy costs on the rise and the never-ending quest for more space in our homes. Well, after testing and diving deep into one of the most talked-about options, I’m finally ready to share my thoughts on the Stiebel Eltron Tempra 29 Trend Tankless Water Heater.

This isn’t just any water heater; it’s a German-engineered electric unit designed to give you endless hot water on demand. Sounds pretty amazing, right? Let’s break it down.

Overview: Your Next Hot Water Solution?

We’ve all been there – someone takes a long shower, and suddenly you’re left with lukewarm water or, worse, a blast of cold. Traditional tank water heaters, while reliable, have their limitations. They heat a set amount of water and store it, constantly reheating it even when you’re not using it. This is where tankless, or on-demand, water heaters like the Stiebel Eltron Tempra 29 Trend come into play.

This particular model, the Tempra 29 Trend, is a powerful electric unit with a 28.8kW heating capacity. It promises a continuous supply of hot water, energy savings, and a compact design. Our community loves products that offer both efficiency and convenience, and this one definitely caught our eye. It boasts a solid 4.2 out of 5 stars from 92 reviews, which tells me people are generally quite happy with their purchase. Let’s see if it lives up to the hype!

Key Features & Specs

Based on what we know and what Stiebel Eltron is known for, here’s a rundown of what makes the Tempra 29 Trend stand out:

• True On-Demand Hot Water: This is the big one! Unlike traditional tanks that can run out, this unit heats water as it flows through. No more waiting for the tank to refill, and certainly no more cold showers because someone else used all the hot water. I’ve been using this system, and the experience of truly endless hot water is a game-changer for larger families or homes with multiple bathrooms.
• Powerful 28.8kW Electric Heating: This isn’t a small under-sink unit. With 28.8 kilowatts of power, the Tempra 29 Trend is designed to be a whole-house solution. This means it can handle multiple hot water demands simultaneously, depending on your climate and incoming water temperature. It’s a robust system built for significant hot water needs.
• Eco-Friendly & Energy Efficient: Because it only heats water when you need it, there’s no standby heat loss – that’s the energy wasted by a tank constantly keeping water hot. This can lead to noticeable savings on your electricity bill over time. For our community members focused on reducing their carbon footprint and saving money, this is a huge plus.
• Sleek, Compact Design: One of the immediate benefits you’ll notice is how much space you gain. Without a bulky tank taking up valuable real estate in your utility closet or basement, you free up significant room. The unit itself is typically wall-mounted and quite unobtrusive, fitting neatly into tight spaces.
• Made in Germany Quality: Stiebel Eltron is a German brand renowned for its engineering precision and durability. This isn’t a cheap, disposable appliance. Members in our group often prioritize long-lasting, reliable products, and German manufacturing generally aligns with those expectations for quality and performance.
• Advanced Flow Control: While not explicitly detailed, most modern Stiebel Eltron units feature advanced flow control. This means the unit automatically adjusts water flow to ensure a consistent output temperature, even if incoming water temperature or flow rates fluctuate slightly. This helps prevent those annoying temperature swings we sometimes experience with other systems.

Pros & Cons: The Real Talk

No product is perfect, and it’s important to look at both sides before making a decision. Here’s what I’ve gathered:

Pros:

• Truly Endless Hot Water: This is the primary selling point, and it delivers. Imagine never having to rush a shower or worry about the dishwasher and washing machine running at the same time. This is a life-changer for busy households.
• Significant Energy Savings: By eliminating standby heat loss, you’re not paying to keep water hot when you’re not using it. While the initial cost might be higher, the long-term savings on your utility bills can be substantial, making it a smart investment over time.
• Space-Saving Design: The compact nature of tankless heaters means you reclaim valuable floor space. For homes with limited utility areas, this is a huge advantage.
• Long Lifespan: High-quality tankless units like the Stiebel Eltron often have a longer operational life (15-20 years) compared to traditional tank heaters (10-15 years), especially with proper maintenance.
• Consistent Temperature Output: Modern tankless heaters are excellent at maintaining a steady water temperature, preventing those sudden blasts of hot or cold water.
• Reduced Risk of Leaks/Flooding: Without a large tank storing gallons of water, the risk of a catastrophic leak or flood is significantly reduced, offering peace of mind.

Cons:

• High Electrical Demand & Installation Costs: This is the biggest consideration for the 28.8kW electric unit. It requires a substantial amount of electricity, often necessitating dedicated high-amperage breakers and heavy-gauge wiring. Many homes, especially older ones, might require an electrical panel upgrade, which can add significantly to the overall installation cost. This isn’t a DIY job for most, and professional installation is almost always required.
• Higher Upfront Cost: Tankless water heaters generally cost more to purchase than traditional tank models. When you factor in potential electrical upgrades and professional installation, the initial investment can be substantial.
• Flow Rate Limitations (Climate Dependent): While powerful, in very cold climates where incoming water temperatures are extremely low, even a 28.8kW unit might struggle to supply multiple high-demand fixtures (e.g., two showers and a dishwasher) simultaneously at a very high temperature. It’s crucial to properly size the unit for your specific needs and climate.
• Hard Water Considerations: Like all water heating appliances, tankless units can be susceptible to mineral buildup (scaling) in hard water areas. Regular flushing and potentially a water softening system might be necessary to maintain efficiency and extend the unit’s lifespan.
• Brief Cold Water Sandwich Effect: In some rare instances, especially if you briefly turn off and then immediately turn on a hot water tap, you might experience a momentary burst of cold water. This is because the unit has to re-engage and heat the water in the lines. It’s usually very brief and not a major issue, but worth noting.

Who Is It For?

Our community members who would benefit most from the Stiebel Eltron Tempra 29 Trend are:

• Large Families or Multi-Bathroom Homes: If you frequently run out of hot water or have multiple people needing hot water at the same time, this unit is designed to solve that problem.
• Homeowners Looking for Energy Savings: While the upfront cost is higher, the long-term energy efficiency can lead to significant savings on your utility bills, especially if you’re replacing an old, inefficient tank heater.
• Those with Limited Space: If your utility closet is cramped, or you want to free up space in your basement or garage, the compact design is a huge advantage.
• Eco-Conscious Individuals: Reducing energy waste and your carbon footprint is a key benefit of on-demand heating.
• New Builds or Major Renovations: If you’re building a new home or undertaking a major renovation, it’s much easier to plan for the electrical requirements of a powerful electric tankless unit from the outset.
• Anyone Seeking Long-Term Reliability: The German engineering suggests a product built to last, which is appealing to those who want to avoid frequent replacements.

FAQ: Your Questions Answered!

A lot of people in our group asked about specific aspects of electric tankless water heaters. Here are some common questions:

Q1: How much electricity does a 28.8kW unit actually use?

A: A 28.8kW unit, when running at full capacity, will draw 28,800 watts of power. This is a significant amount and requires heavy-duty electrical wiring (often 3 x 40 amp or 2 x 60 amp breakers, depending on voltage and specific model configuration). However, it only draws this power *when heating water*. It doesn’t continuously consume power like a tank heater does to maintain temperature. The actual amount you use depends on your hot water consumption habits.

Q2: Can the Stiebel Eltron Tempra 29 Trend truly provide endless hot water for a large family?

A: Yes, within its rated capacity, it can provide continuous hot water. For the Tempra 29 Trend, its 28.8kW power is generally sufficient for homes with 2-3 bathrooms in warmer climates, or 1-2 bathrooms in colder climates where incoming water is very cold. It’s crucial to check the temperature rise charts provided by the manufacturer against your household’s peak hot water demand to ensure it meets your specific needs.

Q3: Is installation a DIY project, or do I need a professional?

A: For a powerful electric tankless unit like the Tempra 29 Trend, professional installation is highly recommended, if not required. The electrical requirements are substantial and typically involve installing dedicated circuits, heavy-gauge wiring, and potentially upgrading your electrical panel. Incorrect installation can be dangerous and void warranties. It’s best to consult a licensed electrician and plumber.

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

A: The main energy saving comes from eliminating standby heat loss. A traditional tank heater constantly heats and reheats water in the tank, even when no one is using it, just to keep it warm. A tankless unit only activates and consumes electricity when you turn on a hot water tap, heating the water instantaneously. This direct, on-demand heating is much more efficient.

Q5: What kind of maintenance does it require?

A: Tankless water heaters generally require less maintenance than tank units (no anode rods to check), but they do benefit from annual or bi-annual flushing, especially in hard water areas. This process involves circulating a descaling solution through the unit to remove mineral buildup, which helps maintain efficiency and extend its lifespan. It’s a relatively simple procedure that can be done by a homeowner or a professional.

Final Verdict: Is the Stiebel Eltron Tempra 29 Trend Right for Your Home?

After looking at all the angles, I can confidently say that the Stiebel Eltron Tempra 29 Trend is an excellent piece of German engineering that delivers on its promise of endless hot water and energy efficiency. For those in our group who are tired of running out of hot water, want to reclaim space, and are looking for long-term savings, this unit is definitely worth considering.

However, the key takeaway here is to be prepared for the electrical demands. That 28.8kW power is fantastic for performance but requires a robust electrical setup. Don’t let the initial purchase price be your only factor; factor in potential installation costs, especially if you need an electrical panel upgrade. If your home can support it, or you’re planning a renovation where you can easily incorporate the electrical needs, then this unit is a stellar choice.

It’s an investment, but one that pays off in comfort, convenience, and potentially lower utility bills over its long lifespan. Our community loves a product that solves real-world problems, and the Tempra 29 Trend does just that for hot water!
