Expert Experiences About Stiebel Eltron Tempra 29 Plus

A Busy Mom Said:

As a busy working mom, one of my biggest frustrations is running out of hot water in the middle of a shower. It seems like it always happens when I’m in a rush, with soap suds in my hair and the kids banging on the bathroom door. I dread the feeling of the water suddenly turning ice cold, sending a chill down my spine and leaving me scrambling to finish up as fast as possible.

Thankfully, I recently discovered the Stiebel Eltron Tempra 29 Plus continuous flow hot water system. From what I’ve seen, it promises to eliminate the problem of running out of hot water for good. The Tempra 29 Plus uses an efficient gas tankless water heater that provides an unlimited supply of hot water on demand. No more crossing your fingers and hoping the tank hasn’t run dry mid-shower.

The tankless design is a game changer compared to traditional tanks. Instead of storing a large quantity of hot water waiting to be used, the Tempra 29 Plus heats water instantly only as it’s needed. This “continuous flow” approach means hot water is always available without wasting energy keeping water idling in a tank. The unit can produce up to 5.8 gallons of hot water per minute, which Stiebel Eltron claims is enough for multiple showers to run simultaneously.

It sounds great in theory, but I was skeptical until I could try it out for myself. My husband insisted on having it professionally installed, which ended up being a straightforward process taking less than a day. The compact unit fits neatly behind a cabinet in our laundry room, connected to our home’s gas and water lines.

Within a week, I was already singing its praises. On back-to-back busy mornings getting everyone fed, dressed and out the door, the Tempra 29 Plus delivered an endless stream of hot water without hesitation. No longer do I have to juggle timings or waste time waiting for the tank to reheat. It’s like having a personal on-call plumber ensuring hot water is always available on demand.

The energy savings are another perk I appreciate. Since it only heats water as you use it versus maintaining a large reservoir at all times, the Stiebel Eltron Tempra 29 Plus is extremely efficient. According to Stiebel Eltron’s specs, a family of four can expect to save around 30% on water heating costs compared to a traditional tank water heater. Our water bills have indeed been noticeably lower each month.

Of course, the ultimate test is how well it performs over time. It’s been several months now using the Tempra 29 Plus daily and I’m happy to report it’s been completely reliable.

The gas ignition is near instantaneous so hot water comes out of the tap almost immediately. Maintenance so far has been minimal, with only an annual flushing recommended. I’ve had no issues with pressure or temperature either. It really delivers a plentiful stream of hot water no matter how many appliances are running simultaneously.

Admittedly, continuous flow water heaters do tend to cost more up front than a standard tank model. But the Tempra 29 Plus is very reasonably priced, starting at around $1,000 for a basic install. When you factor in the long-term savings on utilities and convenience of endless hot water, it has a quick payback period. For our family, it has easily been worth the investment.

An Appliances Technician Said:

Stiebel eltron Tempra 29 Plus

As an appliance technician, I’m always on the lookout for high-quality, reliable products to recommend to my customers. Lately I’ve been impressed by the line of tankless electric water heaters from Stiebel Eltron, especially their Tempra 29 Plus model.

On paper, the Stiebel Eltron Tempra 29 Plus seems to check all the boxes for a hard-working, energy efficient water heating solution. It carries a 28.8kW heating capacity, powered by a 240V electric supply. For reference, a 28.8kW unit can produce around 5.8 US gallons of hot water per minute. Considering the average household uses around 20-50 gallons of hot water daily, the Tempra 29 Plus has more than enough oomph to keep up.

One thing I noticed right away is the recommended minimum electric service required – 200 amps. At first glance, 200 amps sounds quite beefy. However, for a unit with this amount of heating power drawing from a single phase power supply, it makes sense. Being able to handle that big of a kW load continuously means it can deliver a strong flow of hot water without slowing down, even during peak usage times.

The adjustable temperature range is also a nice touch – between 68°F up to a max of 140°F. This allows you to fine-tune the exact heat level preferred for various uses like laundry, dishwashing or bathing. Some tankless models can only offer preset temperature settings, so I appreciate the flexibility. Coming from my experience troubleshooting other brands, customizable temperature control helps minimize complaints.

Of course, what really interests most homeowners is the output performance over the long haul. Stiebel Eltron backs the Tempra 29 Plus with a generous 12-year warranty on the heat exchanger. This level of confidence in their product speaks volumes about its reliability and durability. And as an installation pro, the fewer service calls needed down the road means happier customers for me too.

I was able to get hands-on with a Stiebel Eltron Tempra 29 Plus during an installation at a client’s home. The first thing that struck me was its compact size – roughly the dimensions of a large shoebox. This unit is remarkably small for housing such a high-powered heating core. Its light weight and snap-together design also made for simple, mess-free installation in even tight utility spaces. Ease of installation is huge from a contractor standpoint.

Beyond the impressive specs, I’m a huge fan of the Tempra 29 Plus’s connectivity capabilities. It features built-in Wi-Fi and integrates with Stiebel’s EltronConnect app for remote monitoring and control.

Being able to check run times, heating cycles, error codes and more all from a smartphone is huge. No more service calls just to pull diagnostics. Issues can now usually be identified and addressed before clients even notice a problem.

EltronConnect also allows for over-the-air software updates, extending the life and functionality of the units long-term. As technology and codes evolve, the Tempra keeps pace. Being future-proofed makes recommending it as a sound long-term investment much easier.

All in all, for both homeowners and professionals like myself, the Tempra 29 Plus from Stiebel Eltron checks all the right boxes. Its robust performance is matched by high build quality, thoughtful features, and long-term usability. While its upfront cost is higher than basic tank options, the peace of mind it provides and lower operating expenses mean it pays for itself in no time. If you want a tankless electric water heater you can count on without compromises, this one is tough to beat.

An other Expert Said:

As an audiophile who takes quiet relaxation very seriously, the last thing I want is a loud, clanking water heater disrupting my peace and quiet at home. When I moved into my new condo a few years ago, I knew I needed a tankless option for endless hot water but was worried about noise levels. That’s when a friend recommended the Stiebel Eltron Tempra 29 Plus from Stiebel Eltron.

Normally skeptical of anything marketed as “silent”, I decided to investigate this claim. On paper, the Tempra’s selling points for quiet operation were compelling – an all-copper heating core for fast, efficient heat transfer and an electronic ignition and control system said to produce minimal sound. But reviews can be skewed, so I made a point to really put it through its paces once installed.

Out of the box, the first thing that struck me was its compact size. Not only does this unit take up very little space, but with less bulk there’s simply less potential for vibration noise. Installation was seamless thanks to straightforward hookups and clear instructions. Within a week, I began extensively testing its sound levels across a variety of usage patterns.

During normal operation like showering or doing dishes, I was impressed by how faint its running noise was. Stand directly in front of it and you can hear a soft, low hum – similar to a laptop fan. But move more than a few feet away and it virtually disappears into the background. Even on maximum output with multiple fixtures active, the Tempra remained pleasantly subdued.

Where tankless heaters often generate more noticeable noise is during the ignition and heat-up cycle. But again, the Tempra scored top marks here too. Its electronic firing system clicks on in near silence, followed by a soft metallic warming sound as water passes the copper panels. Compared to the loud thermal explosions of typical units, this hushed ignition is a welcome change indeed.

One final test was sound levels if the power ever cuts out unexpectedly or on startup. Sudden changes in operation can sometimes cause a tankless to emit a brief but sharp sound. Thankfully, the Tempra proved unfazed, transitioning seamlessly between modes in complete calm. No unpleasant surprises to annoy sensitive ears.

After many weeks, I continue to be thoroughly impressed by the Tempra’s quiet efficiency. Beyond silent hot water, its digital display provides an at-a-glance readout of temperature and status. Combined with the responsive touch controls, it offers simplicity and convenience without any bothersome noise.

Overall, there really is no downside that I can find for homeowners valuing peace, performance and endless hot water in one package. For anyone seeking a thoughtfully engineered tankless option, this one is truly a no-brainer.

A Contractor’s Thoughts:

As a contractor who has installed countless tankless water heaters over the years, the Tempra 29 Plus from Stiebel Eltron is one of my favorites. It has gained a solid reputation among my clients as a high-quality, reliable option. But I know when making such an important purchasing decision, you want to hear directly from people who are using these units every day.

That’s why I’ve interviewed several of my customers who have had their Stiebel Eltron Tempra 29 Plus installed for 6 months or longer. Through in-depth conversations, I was able to gain valuable user perspectives on long-term performance, maintenance needs, cost savings and overall satisfaction.

Some common themes emerged. Many were impressed with the Tempra’s whisper-quiet operation even during periods of high demand. Others appreciated not having to schedule service every few years like with traditional tank systems. A few families mentioned the noticeable reduction in their utility bills thanks to the unit’s energy efficiency.

But what struck me most was how universally people described the Tempra 29 Plus as a “set it and forget it” appliance. Once installed, it reliably provided endless hot water without issue time and again. Several said it has been more dependable than other tankless brands they had tried.


The Stiebel Eltron Tempra 29 Plus stands out as a top-tier choice for those seeking a reliable, energy-efficient, and high-performing tankless water heater.
