Exploring Stiebel Eltron Hot Water Systems

With a legacy steeped in German engineering, Stiebel Eltron has been delivering hot water solutions since 1924. Their range of products is designed with the modern consumer in mind - whether it’s a compact apartment or a large family home, Stiebel Eltron has a hot water system that fits.

We shall now examine the various types of Stiebel Eltron hot water systems.

Instantaneous Water Heaters

Stiebel Eltron water heaters, particularly their instantaneous water heaters, are a testament to the company’s commitment to energy efficiency and innovation. Using advanced technology, these heaters provide instant hot water at precise temperatures, eliminating the need for a bulky tank and the accompanying energy losses.

Moreover, their compact design allows them to be installed near the point of use, ensuring convenience by reducing the distance hot water needs to travel through pipes. This not only ensures quicker hot water delivery but also conserves energy, making Stiebel Eltron’s instantaneous water heaters an excellent choice for environmentally conscious households.

Compact Storage Water Heaters

For those in need of a hot water solution for spaces where storage is limited, Stiebel Eltron offers compact storage water heaters. These models are designed to efficiently supply hot water and can be ideally installed under a bench for multi-point use.

One standout model in this range is the SNU 10 unit, featuring a safe tray. It offers a recovery rate of approximately 1 litre per minute, making it an ideal choice for users with high hot water demand. Stiebel Eltron’s compact storage water heaters provide hot water as needed, without taking up excess space.

Under-Sink Water Boilers

Stiebel Eltron’s under-sink water boilers are another testament to the company’s innovative approach to hot water solutions. Designed for compact spaces, these boilers are an ideal choice for residential homes and commercial settings such as office break rooms.

These water heaters cater specifically to single points of use, such as a kitchen sink, and can be operated with one open vented sink mixer, providing immediate hot water for tasks like dishwashing or handwashing. However, they are not intended for boiling water necessary for making tea or coffee, but they efficiently heat water for everyday use.

Readily available at top plumbing stores, these under-sink water boilers offer a handy hot water solution for diverse settings.

Energy Efficiency and Electronic Control in Stiebel Eltron Systems

Apart from offering a wide array of hot water solutions, Stiebel Eltron distinguishes itself through its dedication to energy efficiency and precision control in its systems. Leveraging German engineering and innovative technology, Stiebel Eltron systems provide durable and consistent heating with fast heat recovery and effective regulation during temperature changes.

Intelligent i Technology

Stiebel Eltron’s intelligent i technology is a key component of its systems’ superior performance. This technology comes in various levels—2i for electronic open-loop control, and 3i and 4i for electronic closed-loop control.

The 4i technology is particularly noteworthy. It employs three sensors and a motorised valve to accurately deliver hot water at the set hot water temperature, enhancing energy efficiency. By eliminating the need for manual blending of cold water, it promotes user comfort by delivering consistent hot water temperatures, while also improving air circulation in the system.

Closed-Loop and Open-Loop Control

Stiebel Eltron’s advanced electronic technology ensures precise water delivery temperatures in their instantaneous water heaters. This is achieved through a combination of closed-loop and open-loop control methods.

Electronic open-loop control, or 2i technology, allows for:

• Manual temperature adjustment by mixing in cold water

• Optimized energy efficiency at the selected temperature levels

• Providing the user with a degree of control and flexibility.

On the other hand, closed-loop control, as employed in 3i and 4i technologies, provides continuous monitoring and adjustment for stable and efficient hot water delivery.
