I have 12 kW. This is hell, given the fact that 16.5 kW is brought into the house. An idiotic model that does not have the ability to limit the load in kW on the heating element, and the ingenious solution to rotate the heating elements 100% will give you a wonderful phase imbalance in your network. Of course, you can't turn this off. Ordinary boiler. Because of the boiler, the machine constantly knocks out.  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). |
