Who is the manufacturer
The international company Protherm was founded in 1991 in the Czech Republic. The original production line was located in a plant in Prague and specialized in the production of electric boilers.
Proterm produce quite a few modifications of boilers
The high popularity of the products forced the management of the company to increase production, so the company moved its workshops to the Slovak city of Skalica.
The rapid growth of production led to the fact that already by 1993 the Bear concern occupied 65% of the market for electric heating boilers in the countries of Eastern Europe.
A year later, Proterm begins production of boilers operating on liquid fuel and using two types of gas: liquefied and mains. In 1997 the company acquired the European quality certificate ISO 9001 and started exporting boiler equipment to England and Germany.
At the same time, the company launches a production line for the production of solid fuel and condensing boilers, as well as boilers for heating and storing hot water. In 2013, Protherm starts manufacturing solar collectors.
Since 2010, the Protherm brand has been part of the red brands group of the Vaillant Group trading company, which has thoroughly redesigned the corporate identity of the boilers.

Reviews about Protherm Bear
Protherm Medved is a very well-known brand of gas boilers in Russia, buyers who with the prospect of purchasing these sources of hot water heating, first of all, expect from the model reliability, efficiency in ensuring thermal modes and durability.
Over the course of a number of years of operation, many have not been disappointed with their choice and are happy to share their reviews on the Internet, while not forgetting to emphasize the negative aspects of the device.
Before purchasing any boiler, the user needs to read such reviews in order to take into account all aspects of the unit when buying.
The most typical user reviews for Protherm Bear:
- The Protherm "Bear" KLZ model was purchased before the last heating season. Very convenient design with an additional 90 l tank. The boiler was supplied by the manufacturer as an assembly; during installation, almost no special assembly processes are required, it was simply delivered, unpacked and connected. In terms of time, the installation of the heating system together with radiators and piping took about 2 days. The disadvantage can be attributed to the lack of a system for water purification from scale and suspended solids, therefore it is better to install an effective water treatment system.
- Protherm Medved 40 klom is a sound choice in terms of the balance of functionality-quality-price. The powerful unit reliably and fully supplies the whole family with hot water through an external boiler. Boiler control is very accessible - a row of keys and a large LCD display. For two years of use in different temperature conditions - not a single gripe, although the boiler is still under warranty and is serviced by service specialists.
Description of the floor-standing boiler Proterm Medved
Proterm has been on the market for more than a decade, during which time the company has managed to distribute its products to more than 25 countries around the world. Most users note the high quality and reliability, and this is exactly what you need if you decide to purchase a Protherm Medved 40 klom floor-standing gas boiler. But big sales cannot be achieved without a wide range of products.
Today we will talk about the Protherm Medved 40 klz and 25 kW gas floor standing gas boiler, but in addition to it, the company offers customers a number of expensive devices and a good middle price segment. If in premium technology it can lose to more eminent opponents, then traditional boilers of the Bear series are the best choice in their class. Finding non-Chinese products costing less than 60 thousand rubles is not an easy task. And so that at the same time its creators adhere to their own ideology and high quality standards, something completely unusual. Buying a floor-standing gas boiler Protherm Medved 40 plo and other series, you get:
- High quality products assembled with user care. The Protherm 40 kW gas floor standing boiler, when unpacked, will not creak and crumble on hands, as its competitors in the low price segment can do. And the materials used in the manufacture are the main reason for the durability of the structure. There is stainless steel, cast-iron cooling, and strong metals in the case, and not aluminum, like competitors. Herself .
- High safety standards. The boiler is not only an expensive but also an extremely dangerous asset. In the event of any breakdown, it can fill your entire home with gas.And since single-circuit floor-standing boilers of the Medved series (less than 60 kW) are taken mainly for apartments and small houses, without allocating ventilation and a separate room for them, this can end in an extremely deplorable way. Proterm presents you with the best protection for your money. As soon as the flame goes out, the gas supply will immediately stop, and thanks to protection against short circuits and other trifles, the device will really last for decades.
- Extensive product range. Even the Bear series presents you with up to 12 devices with different power, configuration and scope. The basis of the line is single-circuit floor standing boilers, from 24 to 50 kW of power. Accordingly, you can choose a device that suits your needs and not overpay. But be extremely careful and remember: when using calculators to calculate a suitable device, it is worth throwing 20 percent of the power consumption on top. Otherwise, at peak loads, the AOC (autonomous heating system) will not be able to deliver the required amounts of heat, and "cold zones" will appear.
- Fuel selection. The boilers run on natural and liquefied gas, which allows them to be used not only when connected to the mains, but also, for example, in the country, where you already have to carry a bunch of gas cylinders. And everyone who has been to a suburban area in winter, imagine how much good AOS is needed there, because a standard stove or fireplace is unlikely to save you.
- Economical consumption of resources. In the devices of the company there is a mechanical adjustment of the pressure of the supplied gas. But even without it, the efficiency of Proterm boilers is one of the record in the low price segment. Thus, the devices pay off in just 3 seasons and literally start making a profit, saving you from unnecessary heating costs.

All this looks extremely attractive, but the series also has a number of disadvantages:
- Lack of electronic control, be it a panel or connection to a smartphone. Of course, for such a price it is more of a nitpick, but when compared with boilers that are 10-20 thousand more expensive, there is a desire to save up and switch to electronics. However, do not forget that standard boilers are still better, because they do not depend on electricity and, if it is turned off, they will continue to work without problems.
- The next minus directly emerges from the previous one - the impossibility of spot temperature regulation in the room. The devices have the ability to build up the gas pressure, making the heating weaker or stronger. But it is possible to adjust the warmth of the room more precisely only by trial and error, which clearly does not save the owners of time.
When we have disassembled the products in detail, it is worth discussing the proposed list of models of the Bear series.
Error and Fault Codes
Proterm boilers are very reliable equipment, which is confirmed by more than ten years of experience in using units in Russia and the CIS countries. Almost the majority of failures are caused by disturbances from the outside, in external engineering networks: water, electricity and gas.
Errors in Bear boilers are easily removed
Malfunctions occur in the control unit due to violations in the grounding system of the boiler equipment. The boiler software complex has a good diagnostic system that will not only detect malfunctions in the operation of components and mechanisms and inform the user about them for taking corrective measures
Based codes of malfunctions in the Proterm boilers:
- F00 - the line of the primary sensor NTC2 is open, the temperature of the supply pipe.
- F01 - the line of the primary NTC5 sensor is open, the temperature of the return pipe.
- F10 - short circuit in the line of the primary sensor NTC2.
- F11 - short circuit in the line of the primary sensor NTC5.
- F20 - high temperature of the coolant in the supply circuit above 90 C.
- F22 - low pressure in the heating circuit.
- F23 - high temperature difference between direct and return.
- F24 - low circulation in the heating circuit.
- F25 - flue gas leak in the room.
- F27 - separation of the torch from the burner.
- F28 - low pressure of gas fuel.
- F33 - low air supply to the furnace.
- F49 - low voltage in the mains and at the Ebus terminal block, less than 15 V.
Solid fuel boilers of long burning series KVr and COMFORT are intended for heating various premises, ranging from 50 to 450 m2, suitable for open and closed systems, both with natural and forced circulation. Due to the "top-down" burning method (according to the candle principle) and the large volume of the furnace, a long burning duration is achieved.

A coolant is heated between both cylinders, the temperature and pressure of which is controlled by a thermomanometer. The structure has an opening for loading firewood and an opening for ash removal, closed by upper and lower doors, and a chimney for exhausting flue gases. There are also nozzles for supplying and removing the coolant. To improve the quality of combustion and heat transfer, an air heating chamber is installed in the upper part of the combustion chamber.
There is an opening between the heating chamber and the walls of the boiler through which the flue gases enter the heat exchange cavity.
A telescopic air supply pipe is placed in the chamber, consisting of sections, at the end of which an air distributor is attached. In the upper part of the chamber there is an air inlet and a device for regulating the air supply. On the left side of the boiler, next to the doors, there is a rope for lifting the telescopic air supply pipe. The purpose of the air distributor is to correctly distribute the air in the heat generation zones below, next to the air distributor, as well as in the combustion zones, which are located next to and above the distributor.The air distributor rests on the wood and goes down as the fuel burns.
