Benefits of operation
Installation of a floor-standing chimney boiler
If for other brands of boiler equipment produced earlier, it was mandatory to install a chimney and a separate room for a gas boiler, now such requirements are not relevant. The design of modern units produced by Proterm initially includes a coaxial chimney. And they can be located anywhere in the living space.
Important! Changes in gas pressure in main pipelines are controlled by special automatic devices. They prevent gas from entering the room if the burner goes out
Boilers can have different power levels, so they can heat both small houses and spacious mansions and cottages.
In the designs of heating units of previous times, only atmospheric burners were used. And gas boilers had to be installed in separate rooms with a chimney and its own exit to the street.
Currently, gas equipment is produced with burners of a completely different type, for which such requirements are not imposed.
Proterm heating gas boilers are equipped with all the attributes of safe operation. Despite the fact that gas equipment is manufactured outside of Russia, namely in Europe, it is adapted to Russian conditions - especially to uneven pressure in main networks. Therefore, calls to use only domestic gas boilers have no basis in reality.
Price range
Convection models of Lynx boilers have been discontinued, so it is almost impossible to see them on sale.
Modern types of boilers have a condensing type of design, which significantly increases their cost.
The price range is between 60-65 thousand rubles. depending on capacity and delivery region. Price fluctuations may occur due to logistical requirements.
NOTE! When planning to purchase a boiler, you should add to its cost the costs of delivery, the purchase of additional devices and the conclusion of a warranty agreement. All this will require considerable expenses, for which you need to be prepared in advance.

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. We have already written about how to install a chimney for a gas boiler, so we will not 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. The smoke exits through a 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.
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.
