European gas heating equipment has long become not only competitive in the world market, but also has taken leading positions in some countries. For example, Czech gas boilers Proterm Cheetah is popular in Europe and the countries of the former USSR.
Operating principle and technical features of the equipment
Gepard boilers are produced with a power of 23 kW, while they are capable of providing heating and hot water small residential buildings, apartments in multi-storey buildings and small industrial enterprises. Heating of water and coolant of the heating system occurs in a heat exchanger made of steel. The plate shape of the heat exchanger increases the absorption area of the heat generated by burning natural gas.Residual products formed as a result of gas combustion are discharged through a coaxial chimney, supplied complete with the gas boiler Proterm Gepard 23 MTV, or purchased separately. The flow of oxygen into the closed combustion chamber is produced by a forced ventilation system through the external channel of the coaxial chimney.
For the necessary monitoring and control of the boiler, a small LCD display is provided, located on the front surface. The display clearly shows the current working programm and additional indicators that monitor the normal operation of all components during self-diagnosis. These include:
- Protection against freezing of the coolant in the boiler, automatically turning on circulation pump and the burner when the temperature drops below the specified parameters.
- Overheating protection helps protect your gas boiler Protherm Cheetah 23 MTV from burnout of the firebox.
- Control of gas combustion in the combustion chamber, automatically turning off the gas supply if the burner goes out.
- A draft sensor that turns off the gas supply to the boiler in the event of absence or unstable draft.
The modulation burner makes it possible to smoothly regulate the heating of water and coolant; the load on both circuits can be changed separately. An increase in power and switching of boiler operating modes to DHW occurs as soon as the tap opens hot water. The boiler is capable of supplying up to 11 liters of water per minute, heated to a temperature of +60C, provided that the temperature of the incoming water is around +30C.
If necessary, Protherm Gepard 23 MTV wall-mounted gas boilers can be equipped with a climate control system and weather-dependent equipment that can automatically change the heating temperature when environmental weather conditions change.
Advantages and disadvantages
There are practically no disadvantages to wall-mounted gas boilers Proterm Gepard23 MTV. The only thing is that, like other similar equipment, Gepard 23 is not able to work without electricity. Heaters have many more advantages: - Natural or household gas is a relatively cheap type of fuel, available in any region through central gas distribution lines or pumped into cylinders and.
- The level of harmful emissions is minimal and mainly consists of carbon dioxide.
- The compact dimensions of the equipment allow it to be installed in rooms with limited space.
- Full automation of work processes makes it possible for equipment to operate without human intervention for a long time.
- Built-in safety systems ensure reliable operation of the boiler throughout all operational periods.
Simplified model
A cheaper model of equipment can be considered the gas wall-mounted boiler Protherm Gepard 23 MOV with an open combustion chamber and natural removal of combustion products. This design eliminates the need for installation complex system With forced draft in the firebox and makes it possible to connect boiler equipment to a conventional low-temperature chimney pipe, and not to a coaxial steam exhaust duct. Otherwise, MOV series boilers do not differ from high-quality, technologically advanced boilers of the PROTERM MTV brand.Wall-mounted gas boiler Proterm Cheetah, owner reviews of which help all potential buyers better decide on the choice of attachment gas apparatus, firmly occupies a high place in the ratings of heating equipment.
Modern design and quality of materials, compact dimensions and a maximum range of all necessary functions have made the “Gepard” model a kind of flagship in the line of mounted double-circuit gas boilers from the Slovak company “”.
I propose to look in more detail at the design and differences between models, technical characteristics and prices of gas boilers Protherm Gepard 23 MTV and MOV, the operating instructions for which will help us review the devices of the Slovak manufacturer.
Features of wall-mounted double-circuit gas boilers Protherm Gepard MTV and MOV
Like any European manufacturer of mounted gas boilers, the Proterm company produces several models in the Gepard line. Let's figure out how they differ and what makes them special.
Gas boilers Proterm Gepard
All Gepard boilers have two circuits and two heat exchangers for each of these circuits: the main copper one for heating, and the secondary one for hot water, made of stainless steel. Important distinctive feature boilers of this series are fast heating running water(no more than 2 seconds) in the secondary plate heat exchanger.
Double-circuit gas boilers "Gepard" are produced only in Slovakia and only in two versions:
- With closed camera Gepard MTV combustion;
— with an open chamber (atmospheric) Gepard MOV.
Until 2015, devices in this series had a display small size, and the power of the produced boilers was 11 and 23 kW. Since 2015, the company has modernized wall-mounted boilers Gepard series, replacing the digital display with a brighter and more informative one, installing a new hydraulic group made of higher quality composite materials and an improved SIT gas valve.
In addition, the power of the new boilers became 12 and 23 kW. For example, the Protherm Gepard 23 MTV gas boiler is a double-circuit gas boiler with a closed combustion chamber (with a turbine) with a power of 23-24 kW, and the Protherm Gepard 12 MOV boiler is a double-circuit gas boiler with an open combustion chamber (natural draft) with a power of 12 kW.
