Reviews
User reviews of Proterm Skat electric boilers are positive. But not everyone can understand all the features of electric heating equipment, expecting more from it. You will find detailed information in the reviews.
When we bought a summer cottage, we didn’t even suspect that we would want to live on it almost permanently. We often come here in winter, so last year we decided to install normal heating in the house. Having installed a Protherm electric boiler, we spent a lot of money, but we received the long-awaited warmth. What can we say? It heats properly, we don’t even touch it, there are no leaks or breakdowns, nothing rattles, stinks or rattles. Yes, the bills for electricity turn out to be substantial, but this is the only way to heat the dacha, the nearest gas pipe from which is 10 km away. But it is simply impossible to heat with wood and diesel fuel - the system will freeze while we are in the city.
I work as a sales consultant in a store and sell heating equipment. There are many small settlements near our city that still do not have gas. Therefore, the sale of Protherm electric boilers brings the store good money. Why Protherm? Yes, because this company makes really excellent devices, and not poor crafts in the form of metal pipes with wires. Excellent layout, built-in automation, excellent appearance - what more does the consumer need? Yes, the price is a little steep, especially due to the unstable dollar exchange rate, but this is the only solution for those who do not want to bother with heating, but just want to warm up in their country house.
When I was choosing an electric boiler, I wanted to take a simple Russian model. The devil pulled me to buy a Proterm boiler. I didn’t see the vaunted efficiency, but I spent a lot of money for the equipment. The good news is that I didn’t have to buy a harness, at least I saved on it. So, electricity bills turn out to be astronomical, despite the fact that the winter this year was relatively warm. What will happen then in the cold winter? No, there are no complaints about the equipment itself, it works well. But why do the manufacturer and sellers talk about some mythical efficiency? Here are the gas ones - yes, economical. But what I saw in the bills for electricity was pure horror.
Where gas heating is not possible for safety reasons or due to the lack of a gas main, it is advisable to use electric heating. This is especially useful in places where there is cheap electricity. One of the best in its field is the Proterm electric boiler.
Technical characteristics and appearance
The Proterm electric boiler will fit into any interior due to its small size and wall placement.
As befits good equipment from a well-known brand, Proterm electric boilers are housed in neat, compact housings. Thanks to this, they can fit into any interior, even the most sophisticated. Case dimensions – height 740 mm, depth – 310 mm, width – 410 mm (dimensions are identical for the entire Skat model range). Inside we will find everything you need for the heating system to work:
- Circulation pump;
- Automatic air vent;
- Expansion tank 7 liters.
There is no need to worry about installing the piping - just connect the pipes and radiators, fill the system with coolant, after which you can start testing.
Models with a power of 6 kW and 9 kW can operate from both single-phase and three-phase networks. More powerful ones are three-phase. The equipment is not afraid of power surges and does not cause overloads on the network - a stepwise increase in power is provided here. The maximum current in the circuit when the heating elements are operating is up to 50 A. The maximum coolant pressure in the system is 3 atm, the temperature is up to +85 degrees.
When connecting Protherm electric heating boilers to the electrical network, you must ensure that the cross-section of the wires corresponds to the power consumption.
Layout of inlets for Proterm electric boilers, as well as their dimensions.
Protherm electric boilers are equipped with convenient control panels. They contain LED indicators and liquid crystal displays. Self-diagnosis systems are provided - error codes are displayed on built-in screens. Thermostats are used to create a comfortable atmosphere. Safety systems include an overheating sensor, frost protection, a pressure sensor, a safety valve and an anti-blocking system for the circulation pump.
An interesting functionality is the ability to connect external storage boilers, which are purchased separately.
Popular models
The electric boiler Protherm Skat 9 KR 13 is the most popular. Used to heat rooms up to 90 square meters. m.
As we have already said, electric boilers from Protherm are represented by the only Skat line. Therefore, all equipment has similar characteristics, differing in electrical power and current consumption - all other data is identical, down to dimensions and weight. As for the most popular models, they are designs with a power of 9 kW, 12 kW and 21 kW .
Proterm Skat (RAY) KE 14 connection and configuration.
I consider Protherm RAY (slope) 14 KE to be one of the best electric boilers today in terms of price/quality ratio.
Despite the external similarity to version 13, it has many useful changes.
In this article I will focus on the main points that I consider quite important and to which the instructions for the boiler did not pay attention or did not pay enough attention. Well, as always, we will correct translation inaccuracies).
General description.
When buying a boiler Skat 14 version, you get, as always, an almost complete heating product.
The boiler is already installed:
- Expansion tank
- Circulation pump
- Security group
- Air vent
- Ability to control an indirect heating boiler.
- Possibility of controlling the maximum boiler power, starting from 2 kVA. And if the boiler is connected to a 3-phase network, you can set a power limit both for all and for a specific phase.
- Possibility of controlling a 3-way valve for heating DHW.
- Additional automation options.
I will add that I advise using either antifreeze or prepared water as a coolant, since sediment on electric heating elements quite quickly leads to their failure.
It turns out to be pretty decent functionality for the money.
Heating connection.
The boiler has the ability to connect an outside temperature sensor, a room thermostat, or a boiler sensor. devices via E-BUS and expansion module VR 40 for connecting additional devices.
Let's look at connection options for different heating systems:
Connecting an indirect heating boiler
Rarely will anyone use this function on an electric boiler for three, at first glance, obvious reasons:
- There are electric and combined (indirect + electric heating) boilers.
- Few people use an electric boiler as their main boiler. As a rule, this is a backup heating option.
- Well, it seems stupid to first heat water in the boiler, and then use this water to heat the boiler when using electricity as fuel.
PROTHERM 14 KE board
But, despite the above, heating options have repeatedly been encountered that work only with electric boilers.
Using a heating element for constant heating of water entails the deposition of scale on the heating elements and, as a result, their rather rapid failure.
On the left is a photo of the boiler board indicating what is connected where.
So, we connect the indirect heating boiler to the SKAT 14 KE boiler.
When the boiler switches to the boiler heating mode, the supply temperature increases to 80 degrees. For this reason, it is necessary to turn off the heating supply from the boiler, and direct all the heat to heat the hot water supply.
To do this, you need to install a 3-way mixer, a 220v mixer drive and a boiler sensor (also known as a storage tank loading sensor). The sensor has the original number 0020174087.
Please note that other items will not fit this boiler.
You can buy it in our store. We produce the sensors ourselves, and they are in no way inferior to the original ones, and in some ways they are superior)).
If you bought an indirect heating boiler with a built-in thermostat, you can connect it without a boiler sensor. True, some functions will be unavailable, for example, “boiler temperature”, “freeze protection function”, and the adjustment will be rougher.
The boiler sensor, as well as the contacts of the thermostat built into the boiler, are connected to the same connector (X16), but to different contacts. On the connector itself there is a marking indicating which sensor should be connected where.
The boiler sensor 0020174087 is connected to the X16 connector contacts marked “Tank sensor” and “GND”, the boiler thermostat is connected to the “Aquastat”, “GND” contacts.
The 3-way mixer drive is connected to connector X15. There are also markings on the chip itself. Connection to the “LA” and “LB” contacts of the X15 connector depends on which direction you need to “turn” the three-way valve.
It works like this: when operating in heating mode, the three-way valve allows coolant to flow into the circuit of the heating system and heated floor. The boiler maintains the manually set heating temperature or automatically maintains it according to the equithermal mode schedule (if an external temperature sensor is installed). After the water temperature in the boiler drops, the boiler receives a signal from the boiler sensor, transfers the coolant flow through a three-way mixer to the boiler heating circuit and increases the coolant temperature to the maximum.
After the water has reached the set temperature, the boiler switches the 3-way mixer to heating mode and lowers the supply temperature to its previous values.
I note that the boiler power for heating and hot water preparation can be adjusted independently of each other. The boiler power in heating mode is adjusted in point D.000, and the hot water preparation power in point D.077.
Additional connections Protherm Ray 14 KE.
Proterm 14 KE has several useful features. It’s strange that the manufacturer, having made them, did not find it difficult to describe possible options for their operation and application.
Additional module VR40
The VR40 module is a set of 2 relays with contacts and isolation for connecting additional functions. The module is installed inside the boiler and comes with a set of cables for connecting to the main board. The module is controlled in points D.027 and D 0.028 diagnostic codes. The functionality is small, but sometimes useful.
The module has the original number 0020017744.
Useful little things)
As always, Proterm wrote diagnostic codes and status codes, but did not write how to get there.

Construction of electric boilers
The Skat boiler is equipped with all the necessary modules to ensure a complete heating process:
- Cylindrical heat exchanger made of copper.
- Also copper heating elements. Their power is different to create a multi-stage heating system.
- Expansion tank, volume 7 liters. Performs the function of compensating for the expansion of coolant in the system.
- To carry out forced circulation of coolant in the system, the design has a special pump with three speeds.
- The air accumulated in the system is automatically removed through a special air vent.
- The hydraulic group also has a pressure relief valve to maintain a maximum pressure of 3 atmospheres.
- Thermostat.
- A group of sensors that protect the device from freezing, overheating, and blocking the circulation pump.
Main models
The Skat model range is quite wide due to the different boiler capacities. Such a spread is necessary to fully meet the heating needs of any premises: from small rooms to large industrial premises.
Wall-mounted options are mainly single-circuit devices (but there are also double-circuit ones with the possibility of supplying hot water), created for heating apartments and residential buildings. They are simple and easy to use and install.
Important! Power ranges from 6 to 24 kW. Wall mounting eliminates the need to equip an additional room for a heating system.
Scat 6 kW
A boiler with a production capacity of 6 kW, with proper configuration and a well-thought-out heating system, is capable of heating a house with an area of up to 60 square meters. The power is divided between two blocks of heating elements of 3 kW each. The multi-stage adjustment step is 1 kW. The mass of the modification is 34 kilograms. This makes it possible to install the boiler directly on the wall. Operating voltage 220 or 380 V (works from three-phase and single-phase networks). The equipment has its own simple software, which makes it possible to independently regulate the heating of the coolant.
Electric boiler skat 9 kW
In terms of power supply, this model is also universal: it can be powered from a single-phase network with a voltage of 220 V or from a three-phase network of 380 V. The power of 9 kW between two blocks of heating elements is not divided into equal parts: one of them is 6 kW, the second takes on the remaining 3 kW .
In proportion to the power, the possible area for heating also increases - for this modification it is already 90 square meters. A display is installed on the boiler panel. Which displays basic data about the system and the condition of the coolant.
12 kW
This option operates exclusively on power from a three-phase 380 V network and has two separate blocks of heating elements, each 6 kW.
This boiler provides heating for a home up to 120 square meters. Despite its fairly high power, it is a wall-mounted model.
24 kW
Power mode - from a network with a voltage of 380 V. Heating is provided by four blocks of heating elements of 6 kW each. The largest heating area is 240 square meters. Equipped with a display on the front panel, which displays detailed data on the status of the heating system and the environment. The boiler is also equipped with sensitive step-by-step power adjustment. This allows you not only to select the appropriate temperature regime, but also to ensure significant energy savings.
It is possible to connect an additional circuit for heating DHW to devices of any power and model. For equipment of any modification, the manufacturer provides a warranty period of one year.
Important! To save money on electricity bills, it is recommended to purchase two electric meters for night and day tariffs (if separate payment is provided)
How to put the Protherm Skat boiler into operation?
To start the boiler, you must follow the instructions below.
- The electric boiler is installed by a specialist in accordance with the design documentation.
- Before starting the equipment, a professional provides instructions on the principles of operation of the electric boiler.
- Before turning on the boiler, you should connect to the network , open the taps on the heating circuit and note the pressure level (1 or 2 bar).
- The display shows the settings options.
- The required temperature of the heating system, when connecting a boiler - water supply circuit, and power is set by the consumer himself.
When the pressure is low, the “bar” light starts flashing on the display. To correct the situation, add water to the system. If in this case the pressure decreases, then you need to contact a specialist.
If you need to stop the operation of the Protherm boiler for a long time, you need to disconnect it from the power supply and turn off the taps. If shutdown is necessary in winter, the system must be drained to prevent freezing.

Consumer Reviews
Consumers note that Protherm Skat provided an opportunity where gas connection was problematic or completely impossible. When the power grid is stable, many people refuse to connect to gas, saving considerable amounts of money. In addition, an electric boiler is used in parallel with a gas unit, connecting them to a single heating system. This find allows you to significantly save money on resources by alternating them with each other during the heating season.
If you connect a water heater to Protherm Skat, consumers have the prospect of using hot water. Many people note the perfectly designed design of the boiler, which fits well into any room interior. It can be successfully installed in living rooms; thanks to its silent operation, it will not cause increased attention.
The disadvantages are that when using only a boiler that runs on electricity, there are no alternative heating options when it turns off. Therefore, before purchasing a Protherm electric boiler, you should make sure that there are no problems with electricity. Experts recommend using a voltage stabilizer to ensure normal operating conditions for the Protherm Skat boiler.
In addition, the increased energy consumption of an electric boiler causes negative emotions among the population, since paying bills takes a toll. If we compare the costs of gas and electric heating, the Protherm electric boiler is a little more expensive, with identical heating parameters. From the above, we can conclude that this electrical equipment is chosen by those who do not have the opportunity to connect to network gas, as well as by those who care about the environment and see it as a source of environmental consumption.
Instructions for use
When installing and configuring the device, you must follow safety regulations and use protective equipment. Boilers are installed in a dry place, away from flammable structures, emergency exits, air conditioners and other electrical appliances. Installation in places where water may enter the equipment is not allowed . Also, operation in freezing areas is not allowed.
Mount the equipment on solid walls, taking into account the weight. Heating pipes must fit smoothly and without distortions. Connection to the electrical network is carried out using wires of suitable cross-section, directly to the electrical panel, through additional RCD circuit breakers. To protect against electric shock, the equipment must be grounded. You also need to make sure that the supply voltage complies with the established standards. External components and modules are connected in accordance with the instructions.
Table for calculating the required wire cross-section and fuse rating depending on power
Ideally, the installation should be carried out by certified specialists, but if you follow the instructions and follow the safety rules, nothing bad will happen.
During equipment operation, it is necessary to monitor the temperature in the system and respond to possible errors. If the equipment is working properly, users can only set the desired temperature. The temperature of the heating circuit and the temperature in the external storage boiler (if equipped) are selected using the buttons on the control panel - parameters and errors are monitored using the LCD display.
