What I liked about the "Skat" electric boiler: it's practically silent, compact, and has simple and clear controls. The display shows all the necessary information about the boiler's operation, making it convenient to view. The "Skat" has a high efficiency, and the boiler itself is quite economical. "Skat" solved the heating problem in the house, as it heats both the radiators and the underfloor heating, conveniently. Previously, we had an old Soviet electric boiler, and the electricity bill was almost half as high. "Skat" justified the money spent. silent, economical boiler There haven’t been any breakdowns or problems with it so far; it’s been in use for just under a year and a half. use Protherm Skat 12K 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. |
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 |
The products of the Czech company Protherm are popular in all European countries due to their high performance, compactness and rich functionality. The Skat 12K electric boiler is a profitable equipment for space heating at a price of about $600.
Appearance
The boiler is made in a strict modern design — white colour, a small control panel, a company logo on the front panel of the device. The protective casing is enameled on the outside, so it does not rust, looks good in combination with household appliances, and has thermal insulation on the inside to reduce heat loss.
The size of the boiler 740x410x240 mm is almost the same as that of other models of this class, but the weight is much higher — 34 kg. This is explained by the presence, in addition to the circulation pump, of an expansion tank of 10 liters.
It's a pleasure to use
The unit is equipped with two copper open heating elements with a power of 6 kW each, they can be turned on separately or together, depending on what temperature in the room you need to get. The temperature in the system is regulated from 30 to 85 °C, which allows you to heat a room up to 120 square metres.
Useful extras
In addition to protection against water overheating, the boiler is equipped with power outage protection — after power is supplied, it will turn on automatically without user intervention. When the temperature drops to 5 °C , the ignition will turn on and the system will be protected from freezing of the liquid in the circuit. The water circulation protection function will instantly cut off the electricity supply, and individual parts of the equipment will not overheat. All faults are identified by the self-diagnosis function and shown on the display.
In conclusion, we can say that the Skat 12K electric boiler is worth the money, as it not only does an excellent job of heating rooms, but also does it as safely as possible.
