Having your own heating system allows you to get significant savings due to more effective use equipment, reducing fuel consumption and using equipment only when it is needed.

In European countries, the advantage of this type of heat supply has long been understood, so the production of heating boilers is widely developed there.

Gas boilers, the range of which is quite wide, are recognized as the most rational in terms of economy and ease of use.

The company's products belong to the middle price segment.

Gepard series boilers are for heating and DHW supply to private houses or apartments of sufficient space.

Manufactured in Slovakia, the units fully comply with all European quality and safety requirements.

Gepard boilers are manufactured only in a mounted () version and have separate heat exchanger from of stainless steel and a complete self-control system. They are capable of simultaneously providing power to the heating circuit and supplying hot water, which represents maximum convenience for homeowners.

Attractive appearance and compact dimensions allow the units to be installed in the kitchen or other rooms where they do not stand out among other pieces of furniture.

Types of boilers

There are two models of Gepard boilers:

• Atmospheric (with an open combustion chamber and natural smoke exhaust).
• Closed or turbocharged (a fan is used to supply air to the combustion chamber and force the exhaust gases out).

Models with an atmospheric burner are not recommended for installation in the kitchen due to the possibility of a smoke odor due to external factors impact. For example, strong wind or icing of the chimney can cause a decrease in draft, fraught with smoke in the room.

It is advisable to install atmospheric units in separate chambers with high-quality ventilation.

Turbocharged boilers are completely safe and can be installed in residential areas or in the kitchen.

They are guaranteed to remove exhaust gases, allowing you to maintain clean indoor air..

Both options have a full-fledged self-diagnosis system that constantly monitors the status of all nodes and immediately notifies of the occurrence of emergency situations.

Series models

The Gepard model line is represented by two types of installations:

• Protherm Cheetah 23 MTV.
• Protherm Cheetah 11 MTV.

The choice of one option or another is tied to the area of ​​the house or other premises to be served.

The power indicator approximately corresponds to the area divided by 10. Using this method, you can calculate the most successful indicator for yourself and choose the optimal type of unit.

There is no need to purchase a boiler “for growth”. Excessive power of the unit causes a violation of the operating mode, which quickly disables the components and elements of the boiler. We must strive for maximum correspondence between the power and the size of the room.

Specifications

Let's look at the parameters of the Protherm Gepard 23 MTV boilers:

Device

The design of the Protherm Gepard 23 MTV boiler has a basic composition of components and structural elements that is typical for most convective installations of this type.

The main components of the unit include::

• Gas burner made of chromium-nickel alloy.
• Primary heat exchanger made of copper.
• A hydraulic group that includes a three-way valve, water replenishment and discharge devices, and other elements.
• Secondary heat exchanger made of stainless steel.
• Circulating Grundfos pump.
• Turbocharger fan.
• Expansion tank with a capacity of 5 l.
• Electronic control board with microprocessor attached to external panel with display.
• A system of self-monitoring sensors that continuously monitors the condition of all boiler elements and signals the occurrence of errors.

The boiler operates according to typical scheme. The coolant enters the heat exchanger, where it is heated to maximum temperature.

It is then removed and enters a secondary heat exchanger where hot water is heated. After this, the liquid enters the three-way valve, partially mixes with the return flow and acquires the set temperature corresponding to the set heating mode. After this, the OB goes into the external heating circuit.

Heating is provided by a gas burner, which automatically starts or turns off when the specified coolant temperature limits are reached.

The air supply for optimal combustion is provided by a fan, which simultaneously creates draft to remove gas combustion products. Air intake is made from the external compartment of the coaxial chimney, purchased separately.

The operation of all components is monitored by a system of sensors that monitor the presence of flame, gas or water pressure, and signal any failures or malfunctions. The occurrence of any problems is immediately displayed on the display with an alphanumeric code indicating a particular error.

A complete list of codes is available in the user manual.

Instructions for setting up, connecting and starting

After delivery of the boiler, it is installed on a pre-selected surface. The delivery set includes a special bracket that is mounted on a solid wall. Installation on surfaces covered with plasterboard, thin or temporary partitions with low load-bearing capacity is not allowed.

After installation, all relevant pipelines are connected:

• Gas supply.
• Forward and return lines of the heating circuit.
• Cold water supply.

Work on connecting all communications must be carried out carefully, in compliance with all technology requirements.

Connections gas pipes Check for leaks using a soap solution. After this, the boiler is connected to the power supply network.

It is necessary to control the correct connection of the phase to the corresponding electrode, otherwise the boiler will not start.

Filling with water is carried out until the nominal pressure is obtained, which is shown on the display.

The feed tap opens and the system is slowly filled with water so that air has time to escape. After this, the air pockets in the boiler itself and radiators are released, after which the pressure is adjusted again.

The first start of the boiler is a short-term switching on of the unit to check the functionality and correctness of the connection and settings. Detected malfunctions are immediately eliminated, loose connections are carefully sealed.

Sometimes the first launch is immediately interrupted with the appearance of . This is a consequence air lock in a pump or other component.

The error is cleared and the attempt is repeated again.. Sometimes the first start must be repeated several times until the air leaves the pump. .

NOTE!

Connection and first start-up must be carried out by employees service center, which will correctly set the boiler system settings. Self-configuration and starting the boiler will automatically cancel the warranty agreement and service will be refused.

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 examine in more detail the device and the differences between models, technical characteristics and prices for gas Protherm boilers 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 Cheetah

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 a closed combustion chamber Gepard MTV;
— 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 the wall-mounted boilers of the 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 gas valve SIT.

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.
