Modernization of heating equipment makes it possible to heat the house efficiently and cost-effectively. Modern boilers have high efficiency, they are economical and reliable. The units operate on various types of fuel, making it possible to choose the best option. A popular model of floor-standing boilers is the Bear series from Protherm.
Distinctive features of the Medved boilers
The efficiency of the autonomous heating system is determined by the boiler. The products of the Czech company Proterm are popular among Russian consumers. Boiler equipment of this brand is reliable, durable, offered at an affordable cost. Among the gas units, the Medved boiler stands out for its large dimensions, significant weight and unpretentious operation.
All models of the series are represented by floor-mounted boilers. They are fueled by natural or liquefied gas. It is the most profitable and economical energy resource. The units are equipped with a sectional cast iron heat exchanger. This structural element transfers the thermal energy of gas combustion to the water circulating in the circuit. Cast iron is resistant to corrosion, thick walls of the heat exchanger do not burn out for a long time and do not rust.
Heating equipment is produced in a single-circuit version. It is designed only to heat the house. To increase the functionality of the product, the KLZ model is equipped with an integrated boiler. Tanks for heating water are connected to the rest of the units as an option. The air for gas combustion is taken from the premises. The combustion products are directed to a special collector connected to the chimney. In the absence of draft, smoke accumulates in the upper part of the structure, heating the thermostat. After the sensor is triggered, the gas supply stops.
Protherm offers 4 product lines under the general name Bear. They differ in design features and power parameters. Experts note the high quality of assembly of floor-standing gas units. They rarely break down and go to service centers for repair. The Proterm bear boiler has a significant weight. The mass of models with a capacity of 50-60 kW reaches 200 kg without water. Given their dimensions, a separate room and a solid foundation for the installation of equipment will be required.
Specifications
The main parameters of the equipment:
- maximum pressure - 4 bar;
- noise level - up to 55 dB;
- coolant temperature - 85 ° C;
- average efficiency - 91%;
- power - 20-60 kW;
- protection class against electric shock - IP-40.
The functional burner provides 2-stage power regulation. This allows you to save balloon gas and change the temperature of the coolant in the circuit. For the normal functioning of the equipment, the water in the circuit must have a pH of 7. To prevent mechanical impurities from damaging it, a filter is mounted on the pipe.
Installing an electric ignition simplifies the operation of the units, but models with a piezoelectric element are more relevant with frequent power outages.
Advantages and disadvantages
Proterm products are popular in 25 countries of the world. The demand for equipment is explained by its numerous advantages:
- Strong and durable materials are used in the manufacture - stainless steel and cast iron.
- Eco-friendly heating option does not pollute the environment.
- Equipment operation is controlled by microprocessors.
- The units have a built-in safety system. They provide functions: anti-freezing, protection against blocking of the pump, a sensor for the outlet of combustion products and overheating of the boiler.
- A wide range of models makes it possible to find an option suitable for an individual heating project.
- Availability of management and service. An informative display and a thermostat help to control the processes.
The advantages of the equipment include its versatility. Depending on the power, the models are installed in country houses, apartments, cottages, institutions and industrial workshops.
The disadvantage of the units is the inability to connect control via a remote control. This function is available only for the more expensive Proterm models. Another drawback - free space is required to place the boiler.
Installation and maintenance rules
The Protherm Bear gas boiler is installed on a solid and non-slip base. Its installation is carried out in accordance with state requirements and standards, as well as taking into account the manufacturer's instructions. The room where the structures are located must be well ventilated. The recommended temperature in the boiler room is at least 5 ° C. If the models do not have their own built-in expansion tank and safety valve, then the equipment is installed in the heating system.
Before starting, the water pressure is checked on the pressure gauge, then the gas supply valve is opened. By turning the pilot burner knob, the boiler is put into operation. Its work occurs automatically, according to the set parameters of the thermostat. If the unit shuts down, the burner must be extinguished. Maintenance is carried out once a year before the start of the heating season. The condition of the burner, emergency thermostat, the integrity of the chimney system is checked, the heat exchanger is cleaned. The owner must measure the water pressure in the circuit once a week. If the indicators fall, it is necessary to pour liquid into the system.
Installation and adjustment of heating equipment must be carried out by a specialist. Only then will the manufacturer's warranty be recognized.
Varieties of models of boilers Bear
Heating equipment under the Medved brand is produced not only by the Czech company Proterm, but also by the Russian concern. The domestic manufacturer offers solid fuel boilers for houses with a water heating system. They have a high efficiency of 91%, which is not typical for solid fuel units. In the catalogs of companies or specialized stores, you can choose the best option.
Gas
Floor-standing gas boilers Protherm Bear in the company's catalog are presented in four series.
In line KLOM 4 models from 20 to 50 kW. The stationary boiler is equipped with a sectional cast-iron heat exchanger and a burner that allows you to adjust the heating level. A boiler can be connected to provide the home with hot water. The removal of the gas from the combustion products is natural, but when the turbo attachment is installed, it becomes forced. Convenient electronic ignition system. The units are controlled by buttons or from the display.
Aggregates of the series KLZ designed to operate on main and liquefied gas. They feature a built-in 90 liter boiler. The modulating burner smoothly regulates the power of the equipment. The maximum heating circuit temperature is 85 ° C, DHW 70 ° C. The unit is equipped with a self-diagnosis function, flame control, an electronic ignition system. If the owner wishes, control from an external temperature sensor is connected. There is a water heating timer and a function to turn off the equipment when the set parameters are exceeded.
Boilers Proterm 40 PLO and other modifications of the line are non-volatile.A piezoelectric element is installed for ignition. Models with two-stage power regulation. The boilers are used in private homes and small production halls. They are equipped with a set of thermostats to control the operation of the circulation pump. The unit can be used to heat water if an external 80-200 liter boiler is connected to it. The cast iron heat exchanger ensures long-term operation of the equipment.
Boilers Protyerm Bear series TLO are low temperature units. The models are non-volatile, piezo ignition is installed for the burner. The power of the units is 20-50 kW. The cast iron heat exchanger has 3 to 6 sections. Due to the inertia of the metal, it slowly cools down. Due to its resistance to corrosion, it has a long service life. The boiler is easy to operate, combustion products are discharged naturally. Water is used as a heat carrier.
The manufacturer prohibits pouring antifreeze into the system.
Solid fuel
Long burning
Universal solid fuel boilers for long burning will provide stable heating of the coolant with minimal human intervention. They are capable of functioning on one fuel load for up to 5 days. Continuous operation is possible thanks to top-down combustion technology. Series units Comfort-G and KBp-G are presented in a range of capacities from 8 to 40 kW. The long-burning boiler Bear gives an efficiency of 90%. Due to the use of various types of available fuels (coal, firewood, sawdust), the equipment quickly pays for itself. The use of durable steel in production ensures long-term operation of the units.
Medved gas and solid fuel boilers are economical and reliable in operation. They belong to the middle and budget price segment.
