Outdated Product
This compact boiler can serve as a good solution for apartments or cottages up to 68 m2. First of all, let's pay attention to the fact that the device uses electricity as an energy source — the installation is designed to be connected to a 220V / 50Hz household power supply network. At the same time, the efficiency is at the level of 99.5%. The model is single-circuit, that is, it is intended exclusively for heating, but it is possible to connect a boiler for preparing hot water. Among other things, we note: the control panel is equipped with a display; an extended list of setting codes is provided to adapt the boiler to user requirements; implemented remote control of power supply from the tariff metre; modern set of necessary protection systems.

Very well automated boiler. Powerful and easy to use
1 February 2016 
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.
great model, love it

I spent a long time choosing a boiler for the country house and settled on the Protherm Skat model. We don't have gas, and I'm tired of dealing with wood or searching for fuel pellets. I want to arrive at a warm house, not run around adding wood. A colleague recommended Skat to me. I looked at similar options: they are either fire hazardous, lacking in features, or extremely overpriced. But this boiler is an "all-in-one" type. Clear pros include frost protection; we hardly visit the cottage in winter, so there's no need to worry. It's easy to adjust, very compact, and heats water quickly. We've been using it for over two years without replacing a single heating element, even though we have standard voltage relays on each phase at the house entrance. The service is somewhat expensive, but at least the boiler works well.

First of all, the Protherm Skat 9K electric boiler is designed to work in heating systems. But the ability to connect an indirect heating boiler to it makes the model suitable for organizing hot water supply in the house.

Soft start

The boiler supports operation at capacities from 3 to 9 kW with an increase step of 1 kW. During the first 100 sec. after start-up, the device operates with a minimum power, which allows you to extend the life of the heating elements. The load is distributed on the heating elements of the boiler evenly, as a result of which their equal wear is ensured.

Control

The efficiency of the boiler during the heating season is estimated by high efficiency, the value of which reaches 99.5%. The operation of the model is controlled in two main ways: on its board there is an electronic panel with a display for displaying temperature data and error codes, and among the interface connectors there is an output for connecting a room thermostat. In addition to it, you can install an outdoor temperature sensor, with which the heating intensity will automatically adjust to changes in the street temperature.

Leadership positions

Protherm Skat 9K deservedly occupies a leading position in the electric boiler market. It combines excellent performance, high reliability of all elements, flexibility in control and ease of maintenance, as well as an attractive appearance. And although the reviews about it may seem too flattering, in fact these words are fully confirmed, which makes it possible to call the model one of the best options for everyday use.
