high-quality Czech copper heating elements. in addition, to extend their service life, there is a soft start system - the first minutes after switching on, the boiler operates at a minimum. reliable heat exchanger made of high quality stainless steel. smooth power adjustment. multi-stage power variation is possible with an advanced semiconductor control system. it can turn off individual heating elements or smoothly adjust their power. in a built-in two-speed powerful circulation pump. the maximum working pressure of the pump is up to 5 meters and at the same time it is so quiet that you need to listen to hear it. moreover, when the heating elements are turned off, the pump does not stop immediately, but works for some time in the overrun mode, providing cooling of the heaters. Another plus is that a deaerator is built into the pump. it is possible to link the operation of the boiler with the weather. you bring the sensor outside and the control system will work according to the external temperature. built-in 7-liter expansion tank. there is frost protection. expensive. still, production in the Czech Republic and Slovakia is good in terms of quality, but in terms of price, the option is not the best. like all electric boilers with programme control, you need a good voltage stabilizer. Otherwise, you may lose your warranty. use Protherm Skat 18K month or more |
super boiler! for wealthy retirees "-- former State Duma deputies" after 4 years of operation I am still happy. 3-phase for 18 k.v. heats an area of 160 sq.m. at the night rate so that there is enough heat for the whole day, even in frost of 20-25 degrees. Very satisfied . I definitely recommend it. If you are not "bothered" by electricity bills of 10-15 thousand rubles per month (in winter), then there are simply no disadvantages.  Petr: use Protherm Skat 18K more than year |
After turning on, it operates at minimum power for another one and a half minutes. Even then, the power increases smoothly. All boiler operation data is displayed on the screen. I'm not only talking about the current operating mode or water temperature, but also all sorts of errors. This is a plus, of course, but the display itself is very small, and the necessary data, except for the temperature, is displayed as a code that needs to be deciphered using the instructions or the internet. It doesn't make noise during operation, as sometimes happens with boilers. If you connect an outdoor temperature sensor, the boiler can adjust its power depending on the air temperature in the apartment. This slightly simplifies operation because you have to adjust it less often. Single circuit. I understand that I specifically chose this to save money, but if it could be connected to both the heating system and the underfloor heating, it would be priceless. |
