I have 12 kW. It's a hassle considering that 16.5 kW is supplied to the house. It's a ridiculous model that doesn't allow limiting the kW load on the heating element, and the "brilliant" solution of having the heating elements work alternately will definitely give you a significant phase imbalance in your network. Of course, you can't turn this off. Regular boiler. The circuit breaker keeps tripping because of the boiler.  Dmitriy Prisyazhnyuk: use Bosch Tronic Heat 3500 9 few months |
Gas heating is now an expensive thing, so I will decide to change my old, failed gas boiler to an electric one. Just using the example of the previous boiler, I was convinced of how important it is to make the right choice and not to strive for cheap models. That is why Bosch was my choice. Already one mention of this company inspires confidence in the reliability of the equipment produced by it. An electric single-circuit boiler is simple and reliable. This model has a power of 12 kW and is designed for heating not very large areas. It heats 92 square meters for me, and it must be borne in mind that last year I spent a lot of time, effort and money on wall insulation. But now I save on electricity. It already has a built-in circulation pump and expansion tank. And it is also equipped with an advanced adaptive heater control system that automatically adjusts the number and power of the included heating elements depending on the frequency of operation of the room thermostat. In addition, the electronics independently practice the scheme of alternating switching on of the heating elements, which prolongs their service life. The system is really cool, the Germans know a lot about heating systems) All electric heating is entirely dependent on the availability of electricity. We seem to be stable with this case, but I still had some doubts. Another problem can be the delicate modern electronics of the controller. From the experience of a friend, I know that with the instability of the supply voltage and its strong drawdowns, it is better not to rely on such smart boilers. And yet, be prepared for the fact that you need to supply power to it with a separate three-phase cable of a rather large cross section (8 square millimeters per core). |
Adaptive only in name. Did not live up to expectations. The decision to make the three-pole circuit breaker technically difficult to access, as well as the temperature limiter button (had to cut a corresponding hole in the protective outer casing), is questionable. Adaptivity doesn't work if the radiators get blocked upon heating, and underfloor heating doesn't handle large heat capacity; the boiler starts switching off the heating elements one by one but fails to prevent overheating, leading the limiter to trip and shut off the internal circuit breaker. The display is not informative at all, even compared to Protherm. The method of mounting this display is at the level of cheap China. Declared innovation of adaptability Technical imperfection use Bosch Tronic Heat 3500 24 more than year |

Question about Bosch Tronic Heat 3500 9 Ошибка er11. Как самим можно устранить?
Не понятно почему выскакивает ошибка ер11. Моргает несколько секунд, потом снова нагревает и так по кругу. Батареи греют. Но при поставленом 55 градусах доходит до 60 и тут выскакивает эта ошибка. У меня бош троник 3500 12квт.

Everyone knows firsthand about the high build quality and reliability of Bosch equipment. And indeed, to present any significant claims to the products of the German brand will not work, even with a strong desire. The Bosch Tronic Heat 3500 9 electric boiler is a clear confirmation of this.
Heat source
Often the model is used as the main source of heating in places where electricity is the priority source of energy. Less commonly, the device acts as a backup source of heat supply, replacing gas or solid fuel boilers in which case. With a power of 9 kW, the model can effectively heat an apartment or house with a total area of about 70 m².
Functionality
An alternative function of the electric boiler is the preparation of hot water for the water supply system. For these purposes, the owner of the model will have to acquire an indirect heating boiler. An even higher level of functionality of the boiler is revealed together with a number of additional accessories: a room thermostat, a GSM module for remote control of the device via the Internet or via SMS messages, a thermostat for controlling the operation of underfloor heating, etc.
Equipment
The equipment of the model includes a three-speed circulation pump and an expansion tank of 7 liters. But there is a modification without these components (Bosch Tronic Heat 3000 9), on the purchase of which you can save a little. Both versions of the boiler support connection to 220/400 V power networks and are armed with a useful self-diagnosis function. As a result, Bosch Tronic Heat 3500 9 is a very good, albeit expensive choice for creating a home heating or hot water system.
