Description of Protherm Cheetah

The Cheetah gas boiler is manufactured by Proterm. In principle, it has proven itself well in the Russian market, but at first there were problems with these devices. Some boilers had problems with the software and the work of the "brains". Over time, manufacturers took this into account, and now the occurrence of errors is rather an exception to the rule. There are no complaints about the components, their quality does not raise questions.

Boiler Cheetah - double-circuit

Let's start with the fact that the Cheetah gas boiler is double-circuit. This means that this unit can simultaneously heat the coolant for the heating system, as well as water for hot water supply. This is possible thanks to two heat exchangers.

Heat exchangers are installed in the combustion chamber above the flame - these are coils through which water flows. They are made of copper, to increase the heat exchange area on the coil there are fins. Therefore, in the short time that the liquid is in the heat exchanger, it has time to heat up to the level set by the user.

For heating, the temperature of the heat carrier in the entire system is set, and for DHW, the degree of heating in flow mode. The maximum allowable water temperature for hot water is 65 degrees. At a flow rate of 11.4 l / min, the temperature delta is 30 degrees.

For example, if the make-up from the water supply comes with a temperature of 15 degrees, then the boiler can produce 11.4 liters of water per minute with a temperature of 45 degrees. Boilers Cheetah are equipped with a hot start function. In just 2 seconds, the device heats running water to the required level. That is, when opening the tap, you do not need to drain the water that has not had time to heat up.

The Cheetah boiler has two modes of smoke extraction

The line includes two models of heaters:

with natural smoke extraction 23 MOV;
with forced smoke extraction 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, that is, leaky. The air for the flame in such heaters comes from the room in which it is installed (more precisely, it is 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. For such boilers, a stationary chimney is needed. About, , We have already written, so we will not repeat ourselves.

It does not matter if it is not possible to install a stationary chimney, because. for units with forced smoke extraction, it is not needed (see). Such boilers Cheetah are called coaxial. Smoke comes out through . She is taken outside right 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 hermetically sealed in such units.

Considering, you need to take care of its reliable fixation.

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

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

Complete set and technical characteristics of boilers Cheetah

The gas boiler Cheetah, regardless of the model, is connected to the mains. Wherever you live, power surges or blackouts always happen. Therefore, in order for the operation of heating and hot water to be uninterrupted, it is recommended to install (an uninterruptible power supply). The package of the boiler Cheetah includes:

two-stage circulation pump;
expansion tank 5 l;
microprocessor with the ability to connect an external temperature sensor and an eBus connector;
electrical protection IPX4D.

P, according to the law, is prohibited. The project needs to be redone.

There are different types: manual and automatic.

For DHW there is a make-up pipe. It can also be used to fill the heating system. On the front part there is an LCD display. Specifications:

power: min. 9 kW, max. for 23 MOV 23 kW, and for 23 MTV 24.6 kW;
Efficiency for 23 MOV 89.5%, and for 23 MTV - 91.1%;

Reviews about the product «Wall-mounted double-circuit boiler Protherm Cheetah 23 MTV turbo»

There are no reviews for this product yet. Your review will be the first!

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

Cheetah boilers are produced with a capacity of 23 kW, while they are able to provide heating and hot water to 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 a 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 work program 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.

To improve technical performance and the ability to work in closed heating systems, the Protherm Gepard 23 MTV boiler is equipped with a built-in circulation pump. To remove air from the system, the pump has a bleed valve that automatically eliminates air pockets. The pump has an additional option to protect the circulation pump from shutdown or blockage.

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.

Simplified model

A cheaper model of equipment can be considered a gas wall-mounted boiler Protherm Cheetah 23 MOV with an open combustion chamber and natural exhaust of combustion products. This design eliminates the need to install a complex system with forced draft in the furnace and makes it possible to connect boiler equipment to a conventional low-temperature chimney, and not to a coaxial steam outlet. Otherwise, MOV series boilers do not differ from high-quality, technologically advanced boilers of the PROTERM MTV brand.
