Why Might I Want this Specific Tankless Water Heater?
Simply put, if you are looking for a premium in-home hot water production experience, then the Stiebel Eltron Tempra 29 Plus is for you. This model has taken the best features of many of its competitors—such as a dual chamber heating system and near-perfect energy efficiency rating—and combined them into a single affordably priced unit. Those that previously disliked the old Stiebel Eltron Tempra 29’s analog interface will also be happy to know that this reengineered model makes use of a sleek new digital interface that is far easier to engage with.
Key Specifications and Features to Look for in a Tankless Water Heater
Dimensions & Capacity
For many years, tankless water heaters were difficult to install due their physical size and their necessity for installation space. Modern models like the Stiebel Eltron Tempra 29 Plus, though, are exceptionally sleek and compact, allowing them to be installed with a greater degree of proximity to a high-demand location. This more streamlined design doesn’t affect this model’s capacity, either, because it (like all tankless units) lacks an internal capacity in the first place. For its sleek design and space-saving size, the Stiebel Eltron Tempra 29 earns a 9/10 in our book.
Across the board, tankless water heaters rely on electricity, natural gas, or propane as a fuel source. Each of these fuel types have their own advantages and disadvantages, especially when it comes to installation and ongoing supply costs. The Stiebel Eltron Tempra 29 Plus makes use of one of the most nationally affordable fuel sources, electricity. As such, most homeowners can select this model without spending a ton on installation up front. We give it an 8/10 in this category.
Flow Rate & Water Pressure
A tankless unit’s flow rate describes how rapidly water travels through its core systems, from inlet to outlet. Typically, flow rate is measured in gallons per minute (GPM). Furthermore, it can have a direct influence on an outlet’s water pressure depending on the unit’s proximity to the outlet. The Stiebel Eltron Tempra 29 Plus’ flow rate can reach up to 6 GPM, which is more than enough to maintain water pressure in an extended proximity installation orientation. The Stiebel Eltron Tempra 29 Plus’ Advanced Flow Control feature ensures a constant temperature output no matter how great the hot water demand is in your household. For that, we’re giving it an 8.5/10.
All tankless units include a heating capacity in their listing in order to communicate their core heating capabilities. More specifically, these temperature ranges illustrate the full scope of temperatures to which that unit can heat groundwater during peak performance. The Stiebel Eltron Tempra 29 Plus, for example, features a 68°F to 140°F that remains stable even as demand increases. We’re confident in the Stiebel Eltron Tempra 29 Plus’ capability of providing an endless supply of water with no temperature fluctuations, which is enough to earn it an 8/10.
Energy Efficiency Ratings & Certifications
Many tankless water heaters are built with energy efficiency in mind. The Stiebel Eltron Tempra 29 Plus is a prime example of this, given that it makes use of an industry standard method of communicating a unit’s ability to convert its fuel into heat. In fact, this model carries a 99% efficiency rating, which is remarkable in its own right. Better yet, this model is UL certified, CSA listed, and ETL listed. For its near-perfect efficiency rating, we’re giving it a near-perfect rating of 9/10.
The Stiebel Eltron Tempra 29 Plus’s 3-year warranty for parts is a major added-value feature for this model. That long a coverage is enough to give any user peace of mind, so we’re giving it a rating of 8.5/10.
Of course, you should expect to interact with your tankless water heater regularly. If this process is a hassle (as it often is with analog unit interfaces), you’ll find yourself liking your tankless unit less and less. That won’t be a problem with the Stiebel Eltron Tempra 29 Plus, though, because its digital interface is among the most visible and user-friendly in its class. We’re handing it a 9/10 in this category.
More than its sleek looks and premium materials, the Stiebel Eltron Tempra 29 Plus maintains a low environmental profile with its fully recyclable major components. The solid copper chamber is also burn proof. These things considered, we’re giving it a rating of 8/10.
Different Uses for a Tankless Water Heater
Decentralized In-Home Water Heating
Though the methodology is still fairly new, more and more homeowners are finding that a decentralized hot water production system is well suited to meeting their home’s needs. For example, each module in a decentralized system is easier to install near a high-demand outlet point. This, in turn, cuts down on outlet response times. Also, a decentralized system is easier to maintain due to a decreased reliance on any one appliance for the entire home’s hot water.
Cutting Water and Electric Bills
Every homeowner spends countless hours in search of simple ways to save money on their monthly utility bills. As it turns out, a tankless water heater like the Stiebel Eltron Tempra 29 Plus is a great way to accomplish this goal. The Stiebel Eltron Tempra 29 Plus in particular excels in this category because its patented “Advanced Flow Control” system allows it to more sustainably control its output and hot water production during peak demand scenarios.
Comparing the Stiebel Eltron Tempra 29 Plus to the Competition
Stiebel Eltron Tempra 29 Plus vs. EcoSmart ECO 27
In terms of electricity demand, both the Stiebel Eltron Tempra 29 Plus and the EcoSmart ECO 27 require between 27 and 29 kW on average. However, these models differ when it comes to performance and price. The Stiebel Eltron Tempra 29 Plus is the winner in the performance category due to its 6 GPM peak flow rate, while the EcoSmart ECO 27 comes in at several hundred dollars cheaper than its competitor.
