About Stiebel Eltron

The history of the company began in 1924.

Theodor Stiebel is the founder of Stiebel Eltron. Theodore was not only a businessman, but also an engineer who, in 1924, invented and patented a cylindrical electric boiler that could be immersed in water. Its wall thickness was 3 mm. The invention struck by the speed of heating and cooling.

In 1928, the world saw a small water heater with a power of 1000 W and 2 operating modes, created by the company. Next, a flow heater with a capacity of 3 liters was invented. The device had 2 heating elements, each with a power of 500 W.

Already in 1932, Stiebel Eltron held an exhibition at which they presented their inventions - water-heating tanks with a volume of 3 to 600 liters.

Every year there were more and more products. For the period of 1938, 4,050 water heaters, more than 200 thousand electric boilers and 620 automatic boilers were manufactured, which were used in various industrial sectors.

In the post-war period, Stiebel Eltron was engaged in the production of: pots, pans, stoves for the kitchen, drying and reverberating ovens, electric heating pads and sprinklers. The company also manufactured a flow-type water heater - DH18.

In 1952, Stiebel Eltron entered a new industry - passenger aircraft. The company manufactured water heaters, coffee machines, and aircraft kitchens.
In 1958, a 5-liter boiler was made.

After Theodor Stiebel's death, the company was taken over by his sons. Stiebel Eltron began to produce convection ovens, ironing presses and electric heaters of a new type.Solar systems, solar collectors and heat pumps were also manufactured.

1997 was a successful year, thanks to the creation of System Control Technology. This is a sensor fuel system that was able to control various types of gas, which was located in European countries.

In 2000, Stiebel Eltron introduced the LWZ 303 system. She dealt with the integration of heating systems in an apartment.

In subsequent years, new heat pumps, photovoltaic modules, adsorption chillers and other heating equipment were manufactured.

It should be noted that the company manufactures all the necessary components for water heaters. And factories have a certificate of quality.

At the moment, Stiebel Eltron is in the "Best Water Heater Manufacturers" ranking.

Criterias of choice

Water tank type

1. Principle of operation instantaneous water heater consists in the contact of water and the heating element in the flask of the device. Water heating is carried out immediately after opening the hot water tap.
2. storage water heater involves heating water in a specially designated container of different volumes - a tank.

What are the heating elements?

The following heating elements can be built into the water heaters:

1. Spiral The heating element is characterized by high efficiency, highly precise temperature control and the absence of possible scale formation.
2. Dry heater, has a high level of protection against scale, thanks to a special flask in which it is located.
3. Wet heater quickly heats water, but due to insecurity is prone to scale.

Water heating method

There are such options for heating water:

1. Indirect - heat from another source is taken to heat water.
