In places where there are no water and gas supply networks, electric heating equipment is used to heat the home. Among the market offers is the Proterm Skat boiler. The unit is hung on the wall, small-sized, does not require a chimney device, is powered by a 220 or 380 V network. It is represented by a number of models that differ in performance.
Description of the boiler Protherm Skat
The Slovak company Protherm produces heating equipment. Modification Skat refers to electrical units. These are single-circuit systems that can heat a house with an area of up to 280 m2. They are connected to single-phase and three-phase current.
Protherm models differ in performance. Low-power - Skat 6K and 9K boiler, more powerful Skat 12K, 14K and 18K, 21K, 24K and 28K.
Single-circuit systems are used to heat water in the heating circuit. For hot water installation of a boiler is required. When using it, the boiler is switched from heating mode to water heating mode.
The display indicates the temperature of the hot water and the coolant, a lit light indicates the operating mode, a red indicator warns of equipment malfunction.
Features and specifications
Initially, the Skat Protherm electric boiler is three-phase, however, devices with a power of 6 and 9 kW can be powered from a single-phase 220 V network. Structurally, the Proterm 9 kW electric boiler and other modifications of the brand consist of the following elements:
- Cylindrical heat exchanger.
- Block of heating elements with multi-stage switching.
- Compression expansion tank, volume 7 liters.
- Circulation pump.
- Safety valve.
- Automatic air vent.
A temperature sensor and a device to protect the equipment from overheating are installed on the heating circuit line; there is a frost protection system and a shutdown of the circulation pump.

Advantages and disadvantages
Electric boiler Skat 12 kW Protherm and other modifications of this brand have advantages and disadvantages. The advantages include:
- a large selection of models in terms of power;
- reliable security system;
- Efficiency 99.5%;
- high-quality assembly of elements;
- modern design;
- the ability to connect additional equipment;
- reliability during operation.
Among the shortcomings, we note the following:
- no models with a boiler for heating water for domestic consumption;
- lack of a thermostat in the kit;
- it is unacceptable to use non-freezing liquids as a coolant.
The disadvantages are not significant, they can not be taken into account in accordance with the positive qualities.
Installation and start-up of the boiler
The equipment is hung on the wall with screws. Connect the pipes to the heating pipe. With additional installation of the boiler, a three-way valve is installed in the place of its attachment. They are connected to an electric network of 380 V. A circuit breaker is installed at the input, interrupting the supply of current. A separate power cable is laid for power. All connection points are earthed.
The electric boiler Protherm Skat 9 kW and 6 kW can be connected to a single-phase network using the connecting bridge included in the equipment set. With its help, the phases of the wires on the terminal block are connected. To start the unit, open the water supply tap, bring the system pressure to 2 atm, the temperature will appear on the display and the lamp will light up.
For more information on the operation of the boiler, on setting up various operating modes, see the instruction “Installation and Operation Manual for Skat Protherm Boiler”.
Malfunctions of boilers and methods for their elimination
Proterm boilers are equipped with automatic equipment that responds to faults. Data on this is displayed, each error has its own code. Decoding:
- F00, F10, F13, F19 - malfunction of the temperature sensor;
- F20 - the emergency temperature sensor or thermal fuse does not work;
- F22 - air in the system or low water pressure;
- F41 and F55 - jamming of the relay or contactor;
- F63 - no communication with EEPROM;
- F73 and F74 - malfunction of the water sensor;
- F73 and F74 - freezing of water in a boiler or boiler.
In case of failure of the sensors and pointers, it is necessary to replace or check their connection to the cable line.
If the error on the dry start of the boiler appears on the display, regulate the water supply by opening the valve, increase the pressure in the system. With the formation of air in the pipes, drain the water from them until air escapes.
If the sensor contacts stick, it can be eliminated by turning the button on / off alternately. If the error is not deleted, it is possible that data about it was saved in the system memory. You need to reset to factory settings.
In case of serious boiler problems, call for service to resolve them.
The lineup
This line of equipment is represented by units from 6 to 25 kV. The boilers in the plant configuration are equipped with everything necessary for easy installation and connection. The system is equipped with automation, which ensures operation and shutdown in an emergency.
Electric boiler Proterm Skat 6K
This is a single-circuit boiler with a capacity of 6 kW. It is used for heating rooms up to 80 m2. Current consumption 10 A, efficiency 99.5%, heating temperature adjustable from 25 to 85 0C. Emergency shutdown is performed at 95 0С. To provide hot water, an additional boiler connection is required.
Slope 9K
