Wall-mounted gas boiler Proterm Cheetah, owner reviews of which help all potential buyers better decide on the choice of a mounted gas appliance, 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. An important distinctive feature of boilers in this series is the rapid heating of running water (no more than 2 seconds) in a 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, devices in this series had a small display, and the power of the boilers produced was 11 and 23 kW. Since 2015, the company has modernized the Gepard series wall-mounted boilers, 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.

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 expansion tank of 5 liters.

Let's look at the photo diagram of the device and connection of the gas mounted boiler "Protherm Gepard 23 MTV".

A modern information LCD display reflects the user-set temperature in the heating and hot water circuits. In addition, it shows various error codes in case of malfunctions or breakdowns of the device. It is possible to enable the economical “Eco” mode on the control panel, in which the temperature will not exceed 50 degrees, as well as the “warm floors” 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 that protects the pump from jamming. The hydraulic group of the Gepard 2015 boiler is made of higher quality materials than those of the devices of the previous series. Let's take a closer look at it.

This equipment is inexpensive, high-quality, and also belongs to the middle class and has European quality. You can verify this by reading the characteristics presented below.

Characteristics

Gas boilers "Gepard" of a double-circuit type are used for heating and providing housing with hot water supply. The liquid is heated separately, sanitary water goes to the radiators and the bathroom, while drinking water goes to the kitchen. The system has a built-in water heater, the volume of which can range from 30 to 60 liters. If there are several water intake points in the house, then a larger volume of liquid is consumed, in this case it is best to install the second option.

Single-circuit gas boilers "Gepard" have a maximum flow rate of heated water without unnecessary load. The designs use room temperature controllers, and the heating fluid and water supply system are heated separately. Among the manufacturer’s popular models is the Protherm “Panther 25 KTV”. This is a wall-mounted equipment with a maximum power of 24.6 kW. The device has a closed combustion chamber and costs 33,600 rubles. If we are talking about the Protherm “Cheetah 23 MTV” model, then its maximum power is 23.3 kW, and the cost is 27,600 rubles. The Cheetah series is represented by both closed and open combustion chambers. The first version of boilers can be installed in a room where there is no chimney. This is ensured by a coaxial system, through which gases are removed.

Reviews of the boiler "Proterm Gepard 23 MTV"

If you are interested in Cheetah gas boilers, then you can pay attention to the characteristics of the model mentioned in the subtitle. Installation in an apartment will take a minimum amount of time and money, the equipment will be able to maintain a comfortable temperature. Heating is carried out within the range from 38 to 60 °C for hot water supply, and from 38 to 80 °C for the heating system. According to buyers, the design reacts quite sensitively to hard water, so it is best to take care of the cleanliness of the liquid. For this purpose, a filter is installed. Buyers also like the fact that this equipment is sold without markups, so they can purchase devices at a minimal cost.

Boiler installation

The ceiling height should be 2.5 m. The door width should be equivalent to 80 cm, the unit should be illuminated through openings. The presence of window openings is also stipulated by the rules. For every 10 m2 of room there must be at least 0.3 m2 of windows. When installing a Proterm Cheetah gas boiler, it is important to ensure good ventilation in the room, because gas combustion is ensured by fresh air. The area of ​​the opening for oxygen intake should be equivalent to 8 cm 2 for each kilowatt of power. The pipes through which gas will be transported must be made of metal. Flexible hoses are used only for connecting consumers.

The equipment's power supply system must have a circuit breaker with thermal protection. Gas equipment must be located in the basement of a private residential building. If we are talking about a multi-storey apartment building, then a gas boiler cannot be placed in the basement. The Proterm Cheetah gas boiler must be equipped with a meter. It should be kept at least 20 cm away from it, this also applies to flammable materials. Depending on the power of the equipment, the distance between the wall and the boiler can be from 30 to 50 cm.

Boiler structure

The gas boiler "Gepard 23" consists of a housing, inside of which there is a combustion chamber. The outside of its walls are covered with insulating material. At the bottom there is a gas burner device and an igniter. On top is the main heat exchanger made of heat-resistant steel or cast iron, through which the coolant passes. The secondary heat exchanger is located outside the combustion chambers. An automatic element is installed in front of the burner, which includes a gas valve and a thermostatic regulator. To mix and distribute water flows, it is used. In addition to the main equipment, the device is equipped with a circulation pump, an expansion tank and a fan for forced supply of fresh air.

Main boiler malfunctions

The Cheetah gas boiler, the price of which was mentioned above, may encounter some malfunctions during operation. For example, error f28 on the display indicates that the ignition attempt was unsuccessful. The injectors should be blown out and the gas supply checked. After this, you need to try to re-ignite. But if you see error f75 on the display, this indicates a repeat of the error checking the pressure level. In this case, you should call a specialist to inspect the condition of the heating system.

Conclusion

After installing the Gepard gas equipment, the first settings must be performed by a company specialist. This is required in order to select the most suitable pressure level for the heating system and set the temperature indicators at the desired level. Otherwise, the equipment may not be covered by warranty.

Protherm Cheetah 23 mtv

Let's take a closer look at the Protherm Cheetah 23 mtv boiler. This is one of the most popular models of wall-mounted gas boilers. They are in demand both among owners of private houses and apartment owners in the city.

This boiler attracts attention due to its excellent technical characteristics and relatively low cost in comparison with other Protherm products. . Technical characteristics of the product Protherm Cheetah 23 mtv:

Technical characteristics of the product Protherm Cheetah 23 mtv:

  • installation type: wall-mounted;
  • hot water supply: yes;
  • maximum power: 23.3 kW;
  • combustion chamber: closed (mtv).

As for the combustion chamber, they are either closed or open. Closed chambers are designated in the name of the boiler by the letters mtv, and open chambers by the letters mov.

Gepard series boilers come in both types. However, the greatest convenience is caused by the combustion chamber - mtv, because it allows you to install the device in any room. The fact is that the closed type of chamber does not have a chimney. This is achieved using a coaxial exhaust gas system, that is, a double pipe is used here. This allows you to simultaneously draw in air from the street and remove combustion products.

Install the wall-mounted or wall-mounted model Protherm Cheetah 23 mtv - it's very inexpensive and quick, because it is a flueless boiler. For hot water supply, water is heated in the range of 38–60 degrees, and for heating in the region of 38–80 degrees. If there is a problem with water hardness, the product can quickly become clogged, which will lead to an unexpected shutdown, loss of hot water and knocking. Therefore, you should immediately install a filter.

The cost of the Protherm Cheetah 23 mtv product is not much more expensive than economy class heating equipment. However, he distinguished by good assembly and service life, and also subject to repair. An important point is the installation of the unit, since incorrect self-configuration can lead to a malfunction in the system. Therefore, it is better to seek help from a specialist.

Efficient gas boilers Protherm and features of their installation

After purchasing the boiler, you must check that there is no external damage to the body and that the supplied product is complete. The instructions directly prohibit connecting the gas double-circuit wall-mounted Protherm Cheetah boiler yourself. The installation has the right to be carried out by licensed specialists, so you cannot do without calling a specialist to connect the boiler. The initial start-up of the device and connection to the heating network must be carried out under the supervision of a specialist. You can read how to legally connect individual heating in an apartment.

Attention! Violation of the rules for installing and connecting the boiler may lead to the manufacturer's warranty being revoked.

The Gepard boiler has two smoke exhaust modes

The line includes two heater models:

  • with natural smoke exhaust 23 MOV;
  • with forced smoke exhaust 23 MTV.

This information about the Proterm Cheetah boiler can be found in the instructions. In units with natural draft, the combustion chamber is open type, that is, not sealed. The air for the flame in such heaters comes from the room in which it is installed (more precisely, hung on the wall, since they are all wall-mounted). This is neither good nor bad. You just need to ventilate the room more often. Such boilers require a stationary chimney. About, how to install a chimney for a gas boiler, We already wrote, so we won’t repeat ourselves.

It doesn’t matter if it is not possible to install a stationary chimney, because... for units with forced smoke removal it is not needed (see chimneyless boilers). Such Gepard boilers are called coaxial. Smoke comes out through coaxial pipe. She is taken outside directly through the wall, which is very convenient. The advantage of a coaxial chimney is that it not only removes smoke, but also supplies oxygen to the combustion chamber. By the way, it is sealed in such units.

Considering how much 1 section of a cast iron battery weighs, you need to take care of its secure fixation.

Steel is much lighter, but it also accumulates heat worse.

The circulation of gases in the coaxial chimney (in both directions) is forced. A fan installed above the combustion chamber is responsible for this. It operates from the network, so such boilers consume more electricity.
