But first lets look at the history and credibility of Stiebel Eltron Tempra tankless water heaters.

History of Stiebel Eltron Tempra

Stiebel Eltron began its operations in 1924 in Germany with Dr. Theodor Stiebel being the founder. At first, the primary concern of the company was in the manufacturing of electric water heater whose target market was the German population.

This all started with the invention and eventual manufacturing of coil immersion heaters at his backyard in Reichenberger Straße. It was followed later with the production of the first tankless water heater.

From the late 1960s after the death of its founder, the company began diversification of its products to manufacturing products that utilized renewable energy. Such products included the famous nigh storage heaters.

These heaters could store heat during off-peak and release it during peak periods. Development and manufacturing of the first fully electronic storage heater took place in the late 1970s.

These storage heaters had the ability to supplies precise hot water when needed. The limitation of these heaters is that you couldn’t control the temperature of the hot water.

Once you have set a particular temperature, it meant that the temperature would remain like that. Subsequent innovation has led to the development of an efficient tankless water heater that works at your convenience.

Today, the company prides itself as being a pioneer of advanced Stiebel Eltron electric tankless water heaters with the Stiebel Eltron Tempra model being the most popular and well received in the market and hence this Stiebel Eltron Tempra review below.
