Types and operating instructions for boilers Protherm Skat

In places where there are no water and gas supply networks, electric heating equipment is used to heat the dwelling. Among the market offers is the Proterm Skat boiler. The unit is wall-mounted, small-sized, does not require a chimney, and is powered from a 220 or 380 V. It is represented by a number of models that differ in performance.

Description of the boiler Protherm Skat

The electric boiler Proterm of the Skat modification is designed for heating rooms up to 280 sq. m

The Slovak company Protherm produces heating equipment. The Skat modification refers to electrical units. These are single-circuit systems capable of heating 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 - boiler Skat 6K and 9K, 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 supply, the installation of a boiler is required. When using it, the boiler is switched from heating mode to water heating mode.

The display shows the temperature of hot water and heat carrier, a lit lamp indicates the operating mode, a red indicator warns of equipment malfunction.

Features and characteristics

Initially, the Protherm Skat electric boiler is three-phase, however, 6 and 9 kW devices can be powered from a single-phase 220 V. Structurally, the Proterm 9 kW electric boiler and other modifications of the brand consist of the following elements:

  • Cylindrical heat exchanger.
  • Heating element block with multistage switching.
  • Compression expansion tank with a volume of 7 liters.
  • Circulation pump.
  • Safety valve.
  • Automatic air vent.

A temperature sensor and a device for protecting the equipment from overheating are installed on the heating circuit line, there is a protection system against freezing and against turning off the circulation pump.

Advantages and disadvantages

For a single-circuit boiler, a hot water boiler is connected

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 possibility of connecting additional equipment;
  • operational reliability.

Among the shortcomings, we note the following:

  • there are no models with a boiler for heating water for domestic consumption;
  • lack of a thermostat included;
  • it is unacceptable to use non-freezing liquids as a heat carrier.

The disadvantages are not significant, they can be ignored in accordance with the positive qualities.

Installing and starting up the boiler

Boilers with a capacity of 6 and 9 kW can be connected to a single-phase network

The equipment is hung on the wall with screws. Connect the pipes to the heating pipeline. When the boiler is additionally installed, a three-way valve is installed at the point of its connection.They are connected to an electrical network of 380 V. A switch is installed at the input, which interrupts the current supply. A separate power cable is laid for the power supply. All connection points are grounded.

Electric boiler Protherm Skat 9 kW and 6 kW can be connected to a single-phase network using a connecting bridge included in the equipment set. It connects the phases of the wires on the terminal block. To start the unit, open the water supply tap, bring the pressure in the system to 2 atm, the temperature value will appear on the display and the light will turn on.

More details about the operation of the boiler, about setting up various operating modes can be found in the instructions for installation and operation of the Skat Protherm boiler.

Boiler malfunctions and methods of their elimination

The self-diagnostic system detects errors and displays them on the monitor

Proterm boilers are equipped with an automatic system that responds to malfunctions. This data is reflected on the display, each error has its own code. Decoding:

  • F00, F10, F13, F19 - temperature sensor malfunction;
  • 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 a relay or contactor;
  • F63 - no communication with EEPROM;
  • F73 and F74 - malfunction of the water sensor;
  • F73 and F74 - water freezing in the boiler or boiler.

If the sensors and indicators fail, replace or check their connection to the cable line.

If the display shows an error about "dry" start of the boiler, regulate the water supply by opening the valve, increase the pressure in the system. When airiness is formed in the pipes, the water is drained from them before the air comes out.

If the contacts of the sensors are sticking, this can be eliminated by alternately turning the button on / off. If the error is not cleared, it is possible that information about it has been saved in the system memory. You need to reset the settings to factory settings.

In case of serious boiler malfunctions, call the service department to eliminate them.

The lineup

Boilers with a capacity of 12 kW or more are connected to a three-phase network and heat rooms up to 150 sq. m

This line of equipment is represented by units with a capacity from 6 to 25 kV. The boilers in the complete set of the plant are equipped with everything necessary for simple 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 6 kW single-circuit boiler. It is used for heating rooms up to 80 m2. The consumed current is 10 A, the efficiency is 99.5%, the heating temperature is regulated from 25 to 85 ° C. Emergency shutdown is performed at 95 ° C. To provide hot water, an additional boiler connection is required.

Skat 9K
