Wall mounted gas boiler Proterm Cheetah, owner reviews on which help everyone potential buyers it is better to decide on the choice of hinged gas apparatus, firmly occupies a high place in the ratings of heating equipment.
The modern design and quality of materials, compact dimensions and the maximum set of all necessary functions have made the Gepard model a kind of flagship in the line of hinged double-circuit gas boilers from the Slovak company "".
I propose to analyze in more detail the device and the differences between models, specifications and prices for gas boilers Protherm Gepard 23 MTV and MOV, the instruction manual for which will help us to 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 for heating, and the secondary for hot water, made of stainless steel. important distinctive feature boilers of this series is fast heating running water(max. 2 seconds) in the secondary plate heat exchanger.
Double-circuit gas boilers "Gepard" are produced only in Slovakia and only in two versions:
- with a closed combustion chamber Gepard MTV;
- with an open chamber (atmospheric) Gepard MOV.
Until 2015, the devices of this series had a small display, and the power of the produced boilers was 11 and 23 kW. Since 2015, the company has upgraded wall boilers of the Cheetah 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 has become 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.
Gas boiler Prothem Gepard 23 MTV: instructions and device
This unit with two heat exchangers includes a reliable two-speed circulation pump Grundfos, pneumatic gas valve SIT, the gas burner of the boiler is made of chromium-nickel steel, a membrane expander tank of 5 liters.
We look at the photo diagram of the device and the connection of the gas mounted boiler "Protherm Gepard 23 MTV".

2 - water pressure sensor;
3 - hydraulic group of the boiler;
4 - electric unit with an electric board;
5 - burner ignition electrode;
6 - control electrode;
7 - gas burner of the boiler;

9 - turbine (fan).
Dual circuit mounted boilers heating Protherm Gepard 12 and 23 MTV with a closed combustion chamber and forced draft can be used either with a 60/100 mm coaxial pipe "pipe in pipe" through the wall, or with a separate pipe system through a chimney channel separator - adapter 80/80 mm.
The modern LCD information display reflects the temperature set by the user in the heating and DHW circuits. In addition, it shows various codes errors in case of malfunctions or breakdowns of the device. It is possible to turn on the Eco mode on the control panel, in which the temperature will not exceed 50 degrees, as well as the "warm floor" mode.
A room thermostat for setting the operating mode of the unit depending on the air temperature in the house is not included in the “wall-mounted” package, but is an option that can be purchased and connected separately.
The circulation pump has an automatic air vent and a post-circulation function to protect the pump from jamming. The hydraulic group of the boiler "Gepard 2015" is made of more quality materials than the devices of the previous series. Let's look at it in detail.
Hydraulic group of the boiler Proterm Gepard
1 - safety valve for 3 atmospheres;
2 - pressure sensor in the system;
3 - plate secondary heat exchanger for hot water from stainless steel;

Designations of wall-mounted gas boilers PROTHERM Cheetah:
11
- boiler power.
MOV– open combustion chamber, hot water heating in flow mode.
MTV– closed combustion chamber, hot water heating in flow mode.
European gas heating equipment has long been not only competitive in the world market, but has also taken a leading position in some countries. For example, Czech gas boilers Proterm Gepard are popular in Europe and the countries of the former USSR.
The principle of operation and technical features of the equipment
Boilers Cheetah are produced with a capacity of 23 kW, while they are able to provide heating and hot water small residential buildings, apartments in high-rise buildings and small industrial enterprises. The heating of water and the heat carrier of the heating system takes place in a heat exchanger made of steel. The lamellar form of the heat exchanger increases the area of absorption of heat produced as a result of burning natural gas.The residual products formed as a result of gas combustion are removed through coaxial chimney supplied with the Proterm Gepard 23 MTV gas boiler, 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 control and management 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 the circulation pump and the burner when the temperature drops below the set parameters.
- Overheating protection allows you to protect the gas boiler Protherm Cheetah 23 MTV from burnout of the furnace.
- Control of gas combustion in the combustion chamber, automatically shutting 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 a lack or unstable draft.
The modulating burner makes it possible to smoothly adjust the heating of water and coolant, the load on both circuits can be changed separately. The increase in power and the switching of the boiler operating modes to DHW occurs as soon as the hot water tap is opened. 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, wall-mounted gas boilers Protherm Cheetah 23 MTV can be equipped with a climate control system and weather-dependent equipment that can automatically change the heating temperature when the weather conditions change.
Advantages and disadvantages
There are practically no drawbacks to wall-mounted gas boilers Proterm Gepard23 MTV. The only thing - like other similar equipment, Cheetah 23 is not able to work without electricity. The advantages of heaters are much more: - 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 mounted in rooms with a limited area.
- Full automation of work processes makes it possible to operate equipment without human intervention for a long time.
- Built-in security systems ensure reliable operation of the boiler throughout all operational periods.
