Heating boilers "Bear": design features of various models and functionality

There are a great many modifications of gas heating equipment on the market. But even with a significant number of competitors, the “Bear” boiler from Protherm takes one of the leading positions. This is largely due not even to the advertising campaign, but to the ability of Czech engineers and specialists to perform the task properly.

Floor-standing gas boilers from Protherm show themselves equally well in country houses and city apartments. Judging by the reviews of the owners, the control panels are quite ergonomic, and the automatic control of the parameters satisfies the most stringent requirements.

They also have such advantages as:

• the strictest environmental safety;
• possibility of prolonged action without adjustments;
• compactness, that is, the ability to use the device in a limited area;
• a wide variety of models, allowing you to choose the best option for yourself;
• carefully thought-out security measures that almost completely eliminate gas leaks;
• outstanding reliability and stability of action.

The TLO version can have power from 18 to 45 kW. In comparatively small houses and cottages, the 30 TLO system became widespread, providing hourly output of up to 30 kW of heat. This unit is able to supply both heating and water supply, and indirect heating boilers. There is a pipe through which the liquid will go to the remote heat exchanger. This design, according to information from the manufacturer, can be applied in heating systems with a gravitational course of water.

Even more in demand variations KLOM 20, 40. They optimally manifest themselves in heating and in the production of hot water. Productivity is quite high, manufacturability meets the needs of most consumers. It is quite easy and simple to operate the boiler. Product 50 KLOM provides an efficiency of 92%. It is optimized for operation in a closed heating system with pumpingpumping coolant.

For those who prefer stationary heating equipment is designed model 30 KLZ. Inside this mechanism is a boiler, designed for 90 liters of very hot water. The boiler is equipped with a modulating burner, power can vary from 0.7 to 1 nominal. Version 50 KLZ is the most powerful in this line and is ready for use. Such a boiler can be put into operation without the slightest installation work.

The KLOM 50 is equipped with a modern modulating burner. The heat exchanger is made of cast iron and is characterized by increased heat transfer, removal of gaseous products of combustion can be carried out both with the help of a fan and in a natural mode. The scheme is easily adaptable for connecting external boilers, and eutectic automation facilitates seasonal control. To obtain heat can be used both natural and liquefied gas. Designers took care of the reliability of the thread on the screw feet.

The developers paid special attention to the safety of operation of all parts.

There are:

• smoke detector;
• the automatic block excluding an overheat;
• prevention of pump seizure.

The LCD screen informs consumers of all important parameters, but it is not filled with excess information, which would only confuse the matter. The pressure generated in the heating circuit varies from 1 to 4 bar. The greatest warming up of water reaches 90 degrees. The net weight of this boiler is 150 kg.

Product 40 KLOM is equipped with an electric ignition option., it is recommended for installation in residential and country houses, and also in small production and office premises. The adjustment of the generated power is made smoothly. A fan can be supplied pumping out flue gases. With a mass of 130 kg, the device is equipped with an open gas firebox and is designed for a nominal pressure of natural gas of 130 mm. waters st. (for liquefied - 300 mm. water. Art.).

Cascade bundle of these boilers is not provided. Installed 5 sections.

From automation there are:

• thrust meter;
• means of preventing freezing;
• anti-lock knot on the valve with three strokes;
• fire observation;
• overheating protection.

The PLO variation, as reported by the manufacturer, is equipped with a traction force sensor and a device that controls the fire. Floor-standing cast iron boilers can produce from 17 to 49 kW of thermal energy. Power control has one or two stages of switching forces in various modes. The 20PLO subspecies is capable of operating on liquefied gas, but it does not accept diesel and solid fuels (like other versions in the line). Injector-type burner, with no modulation of the flame.

Three sections allow you to get 17 kW of heat with an efficiency of 90%. Working pressure ranges from ½ to 3 atm. Indication of temperature and pressure is provided, Exabasic functions, Exacontrol also work stably. The switch from winter to summer mode is thought out; Electrical protection category - IP20. In all PLO boilers, the plug-in circuit must have a diameter of 1 inch.

In KLZ17, the differences between the versions are relatively small: the 20th version has 3 sections, the 30th has 4, 40 KLZ17 has 5 sections, and 50 KLZ17 has all 6. It does not affect the efficiency - it is 90% everywhere.The recommended expansion tank capacity is 10 liters. Systems are equipped with built-in fault indication, there are functions Thermolink P, S.

Returning to the KLOM system, it should be noted that its preference by many consumers is due precisely to the broad functionality:

• built-in thermometer and manometer;
• simplified ignition in the automatic version;
• gas control and protection against overheating (freezing);
• warming water from 45 to 85 degrees;
• connection to a single-phase network of 220 V;
• two compatible water heaters (giving out 25 and 46 liters of water in 60 seconds).
