Frequently Asked Questions
- How do I choose the right output for a BOSCH electric boiler? As with gas boilers, base your choice on the calculated heat loss of the building to be heated. For electric boilers it is also crucial to check whether the capacity of your electrical connection to the house (flat) allows it - higher outputs (from roughly 12 kW upwards) usually require a three-phase 400 V connection and a correspondingly sized main circuit breaker, which will be confirmed by a revision technician or directly by the electricity distributor.
- Is an electric boiler worth it compared to a gas or solid-fuel boiler? An electric boiler has the lowest purchase price and the simplest installation (no flue gas extraction is needed, since it burns nothing), but operating costs for electricity are usually higher than for gas or wood/coal for the same amount of heat delivered. It is particularly suitable where gas is not available, as a supplementary/backup source, or for a building with low consumption (well-insulated new builds, cottages, flats).
- How does an electric boiler regulate output? Most models switch individual heating elements on/off gradually (in stages); some more modern models also allow smoother output modulation - this affects the smoothness of heating and, to some extent, the service life of the switching components.
- Can I install this electric boiler myself? Connection to the electrical network, inspection and commissioning must be carried out by a person with electrotechnical qualification in accordance with the applicable standard STN 33 2000 and related regulations - DIY installation is not permitted, either for warranty or safety reasons.
- Can this electric boiler also heat domestic hot water? For many models, yes, usually in combination with a separate domestic hot water tank and a switching (3-way) valve, which switches between the heating circuit and heating the tank - the exact possibility and required accessories for this particular model can be found in the technical parameters above, or consult our customer service.
This particular BOSCH model has an output of 6 kW - as a rough guide, this corresponds to an electric current considerably higher (with a three-phase connection) than you would expect from a typical household appliance, so it is necessary to check the capacity of the house circuit breaker and connection in advance.

For more than 125 years, we have been supplying the market with efficient, easy-to-operate and at the same time reliable equipment that creates warm and cozy homes for people. Bosch Thermotechnology today offers its customers worldwide solutions for room climate, hot water and decentralized energy management.
Since 1932, the brands Junkers and Bosch have been united by a strong partnership. The merger enabled the combination of traditional craftsmanship with the most modern technology. Under the Bosch brand, we now focus on the future with intelligent building technology, in which thermal technology plays an important role.
The traditional brand Junkers continues, because history, tradition and experience are still embedded in every Bosch-branded product. Junkers means more than 120 years of proven technology and the highest quality for us; we proudly created a memorial for this brand with its own museum. At the company in Wernau, we present the continuation of the history and the life's work of the founder Hugo Junkers.
History
In 1886, Robert Bosch founded the "Workshop for Precision Mechanics and Electrical Engineering" in Stuttgart. This was the beginning of today's globally active company. From the very beginning, innovation and social responsibility were characteristic of the company.
1886 - 1905 - The history of the Bosch company begins with many first steps. Steps toward independence, into the automotive market, into markets outside Germany and into the main production hall.
1906 - 1925 - The company's first astronomical global upswing was brutally interrupted by World War I, after which the Bosch company had to transform and focus on innovation to cope with its consequences.
1926 - 1945 - The Bosch company coped with the speed of the economic crisis and the dictates of National Socialism through the power of innovation and perseverance, until World War II brought enormous challenges once again.
1946 - 1959 - At the end of World War II, the Bosch company lost its international branches for the second time. A large part of its production facilities lay in ruins. The following two decades were devoted to reconstruction, but also to entering new business areas.
1960 - 1989 - The period between the 1960s and 1980s was marked in the Bosch company by a transformation that turned it into a diversified group of independently managed divisions, a global company and a market leader in the field of automotive electronics.
1990 - 2016 - The Iron Curtain fell, new markets emerged in Asia and software opened up new opportunities for Bosch. The last three decades brought rapid economic change, which the company had to face head-on.
