Brand Overview
German Engineering, Over 100 Years of Tankless Innovation
Stiebel Eltron is the international pioneer and leader in electric tankless water heating technology, with more than 100 years of development and over 20 million tankless units manufactured worldwide. Founded in Germany in 1924, the company's engineering and manufacturing tradition delivers some of the most advanced electric tankless water heaters available in North America.
Unlike most tankless brands that focus primarily on gas-fired units, Stiebel Eltron specializes exclusively in electric tankless water heaters. This singular focus has allowed them to develop proprietary technologies like Advanced Flow Control and precision self-modulation that no competing electric tankless manufacturer can match. For Houston homeowners considering an electric tankless water heater -whether as a whole-house solution or a point-of-use supplement- Stiebel Eltron represents the gold standard in the category.

Why Houston Homeowners Choose Stiebel Eltron Tankless
- Patented Advanced Flow Control™ (Tempra Plus): Stiebel Eltron invented Advanced Flow Control and holds German patent DE 3805441 C2 for the technology. If hot water demand exceeds the unit's capacity, the system automatically reduces flow slightly to maintain the set temperature- you never get a cold surprise.
- Self-Modulating Energy Technology: Every Tempra model continuously monitors incoming water temperature, flow rate, and output temperature through multiple sensors. A proprietary microprocessor engages heating elements in stages, using only the minimum energy needed to maintain the desired temperature.
- Ideal for Houston's Warm Climate: Electric tankless water heaters perform best where groundwater temperatures are higher. Houston's warm groundwater means Stiebel Eltron units can serve whole-house needs with lower kW models, maximizing efficiency and minimizing electrical infrastructure requirements.
- Completely Silent Operation: With no mechanical switches, no combustion, and no venting, Stiebel Eltron electric tankless water heaters operate in complete silence- a significant advantage over gas-fired tankless units.
- No Venting Required: As electric units, Stiebel Eltron tankless water heaters eliminate venting entirely. No PVC runs, no roof penetrations, no combustion air concerns- simplifying installation and reducing costs.
- Compact, Space-Saving Design: Tempra units are roughly the size of a briefcase and can be wall-mounted close to the point of use, freeing up valuable floor space and reducing the wait for hot water at the tap.

Installation Notes
Stiebel Eltron Tankless Water Heater Installation in Houston
Installing a Stiebel Eltron electric tankless water heater requires careful evaluation of your home's electrical capacity. Whole-house Tempra models require dedicated circuits with appropriate amperage- ranging from 50 amps for the Tempra 12 up to 150 amps for the Tempra 36. Our licensed Houston electricians and plumbers work together to assess your existing electrical panel and determine whether an upgrade is needed before installation.
The good news for Houston homeowners is that our warm groundwater temperatures (typically 70°F+) mean lower-kW Tempra models can effectively serve whole-house needs, reducing the electrical infrastructure requirements compared to northern climates. A Tempra 24 Plus or Tempra 29 Plus is often sufficient for most Houston households.

Some common issues with tankless water heaters include insufficient hot water supply, fluctuating water temperatures, and mineral buildup. Regular maintenance and proper sizing can help mitigate these problems, ensuring your unit operates efficiently and effectively.
Tankless water heaters work by using powerful heating elements to warm water as it flows through the unit. When you turn on a hot water faucet, cold water enters the heater, and the heating elements activate to provide hot water instantly. This process eliminates the need for a storage tank, allowing for a more compact design and continuous hot water supply.
Tankless water heaters typically have a longer lifespan than traditional tank heaters, often lasting 20 years or more with proper maintenance. This longevity can make them a more cost-effective option over time, as they may not need to be replaced as frequently.
Switching to a tankless water heater can lead to significant energy savings. Because they only heat water when needed, they can reduce energy consumption by up to 30% compared to traditional tank heaters. This not only lowers utility bills but also reduces your carbon footprint.
Frequently asked questions about tankless water heaters often include inquiries about installation costs, energy efficiency, maintenance requirements, and how they compare to traditional tank heaters. Addressing these questions can help potential buyers make informed choices.
Installing a tankless water heater may require specific modifications to your plumbing and electrical systems. It's essential to consult with a licensed professional to ensure that your home meets the necessary requirements for safe and efficient installation.
Regular maintenance is essential for keeping your tankless water heater running efficiently. This includes descaling the unit to remove mineral buildup, checking the filters, and ensuring the vents are clear. Most manufacturers recommend annual maintenance to prolong the lifespan of the unit and maintain optimal performance.
Reading reviews from other customers can provide valuable insights into the performance and reliability of different tankless water heater models. Look for feedback on energy efficiency, ease of installation, and customer service experiences to make an informed decision.
Choosing the right size tankless water heater is crucial for meeting your household's hot water needs. Factors to consider include the number of fixtures that will be used simultaneously and the temperature rise needed.

Tankless water heaters are ideal for various applications, including residential homes, commercial buildings, and even recreational vehicles. Their ability to provide hot water on demand makes them versatile and suitable for a wide range of hot water needs.
The primary difference between tankless and tank water heaters is how they store and heat water. Tank water heaters store a set amount of hot water, while tankless models heat water on demand. This results in tankless heaters being more energy-efficient and providing a continuous supply of hot water, but they may have higher upfront costs.
Most tankless water heaters come with a warranty that covers parts and sometimes labor. Warranties typically range from 5 to 15 years, depending on the manufacturer and model. It's important to read the warranty details to understand what is covered and for how long.
A tankless water heater, also known as an on-demand water heater, heats water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, where it is heated by either gas or electricity. This means you can have a continuous supply of hot water, making it an efficient choice for many households.
