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 can be immersed in water. Its wall thickness was 3 mm. The invention was striking in the speed of heating and cooling.

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

Already in 1932, Stiebel Eltron held an exhibition, where it presented its 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, the Stiebel Eltron company was engaged in the production of: pots, pans, stoves for the kitchen, drying and reflective ovens, electric heating pads and sprinklers. The company also manufactured a flow type water heater - DH18.

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

After the death of Theodor Stiebel, his sons took over the company. Stiebel Eltron began to produce convection ovens, ironing presses and electric heaters of a new design. They also produced solar systems, solar collectors and heat pumps.

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

In 2000 Stiebel Eltron presented the LWZ 303 system. It was involved in the integration of heating systems in an apartment.

In the following years, new heat pumps, photovoltaic modules, adsorption refrigerators and other heating equipment were manufactured.

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

At the moment the company "Stiebel Eltron" is in the rating "The best manufacturers of water heaters".

Criterias of choice

Type of water heater

1. Principle of operation instantaneous water heater consists in the contact of water and a heating element in the flask of the device. The water is heated 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 heating elements are there?

The following heating elements can be built into water heaters:

1. Spiral the heating element is characterized by high efficiency, high-precision temperature control and no possible scale formation.
2. Dry heating element, has a high level of protection against scale, thanks to a special flask in which it is located.
3. Wet heating element heats water quickly, but due to insecurity it is prone to scale.

Water heating method

There are such options for heating water:

1. Indirect - to heat the water, heat is taken from another source.
2. Gas - gas is used for heating. A water heater with the ability to operate on reduced gas will save the consumed amount of gas.
3. Electric - power supply is required for heating.
4. Combined - indirect and electrical heating.

Water connection and installation

Eyeliner can be installed from the top, bottom or side. Depending on the place of installation and dimensions of the device.

Installation can be wall-mounted (horizontal, vertical), built-in or floor-standing.
