Electric boilers are in demand among owners of country houses, residential cottages and other non-gasified buildings. They are characterized by good functionality and allow you to heat any buildings that are not connected to gas mains. Their typical representative is the Proterm electric boiler - this is a device from a well-known manufacturer, characterized by high build quality and decent characteristics.
Equipment from such a renowned manufacturer really deserves special mention, so we will tell you everything we know about Proterm boilers.
Features of Proterm electric boilers
By installing such an electric unit in your home, you are making an excellent choice. Rather than buying equipment from dubious brands, it is better to overpay a little and take a really worthwhile item from a well-known manufacturer - the performance of the entire system depends on the quality of the boiler used. Moreover, the Protherm company has extensive experience in the production of electric heating equipment.
There is only one model range - Skat.
Heating a home not connected to gas mains is always a big problem. Electric boilers existing on the market are either high cost or cannot boast of sufficient functionality. In this case, you always pay attention to small-sized and neat gas models that operate automatically and do not clutter up the space. The Protherm company is ready to offer owners of country houses similar solutions, but powered by the electrical network.
Protherm electric boilers are a unique solution that is economical. They are installed in both residential and non-residential buildings, regularly generating heat. They are presented in a single model range called Skat - customers can choose from samples with thermal power from 6 to 28 kW. Thanks to this, they can heat rooms up to 280 square meters. m.
What are they good for?
- Simple single-circuit design - if you like simple and reliable equipment, you will definitely like the products of this brand;
- Wide power range – it is possible to choose a device that is suitable in terms of power and price;
- High efficiency - efficiency, according to the manufacturer, is 99.5%. This means that almost all of the expended electricity is converted into heat, without significant losses;
- Absolutely silent operation - even if the equipment is in the bedroom, it will not interfere with a good night's sleep;
- Precise temperature control – create a comfortable and cozy atmosphere in your home;
- Availability of universal models - they can operate from single-phase and three-phase networks with a voltage of 220 or 380 V;
- Easy installation - you can handle the installation yourself, without the help of specialists.
Prices range from 37,900 to 47,000 rubles - this is the official price from the manufacturer as of April 2016. In some other stores it may differ up or down (usually more). But nothing will stop you from buying a Proterm electric boiler in the official online store - this is the most economical and reliable option.
The cost of the equipment may seem high, but Protherm always stands behind the quality of its products.
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 .
In addition, the Skat model range includes models with a power of 6 kW, 14 kW, 18 kW, 24 kW and 28 kW - the maximum heating area depends on the power (calculations must take into account heat loss and the possibility of connecting a 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.
Advantages
The Proterm electric boiler has a number of positive features that distinguish it from devices from other manufacturers:
- High quality components and good assembly.
- Reliable and durable design.
- A wide range with different power options for units for any room.
- Reliable security system.
- High efficiency (up to 99%).
- The ability to be equipped with additional modules, acquiring new options and the ability to perform new tasks.
- The manufacturer has a good reputation among Russian users.
The Protherm electric boiler also has some negative properties:
- Quite a high price (starts from 35,000 rubles).*
- Antifreeze liquid is prohibited for use as a heating system filler.
- The device does not include a compact thermostat for use in a room.
- Despite the wide range of models, there is no factory modification that would provide for heating water for household purposes using a boiler method.
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.

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.
Automation protective functions:
Protection of the boiler from water freezing (at less than +8°C water temperature, the pump automatically starts pumping water)
Protection of the pump from jamming
Remembering set parameters during power outages
Safety valve with opening pressure 3 bar
And this is what a Protherm boiler looks like connected to the heating system. A dial indicator for water pressure in the heating system is also visible.
As an example, I show you a Protherm electric heating boiler fully connected and installed in the basement of a private house.
