Features of Proterm boilers

To make the operation of Slovak gas equipment Protherm comfortable, it is necessary to connect and configure it correctly. Maintenance must be carried out annually; the instructions included with each piece of equipment will tell you more about this. The kit also includes a technical data sheet and connection diagram. The main competitors are Czech THERMONA boilers; they are comparable to the Slovak brand in terms of price and functionality.

Single-circuit versions heat areas up to 350 m². Double-circuit ones are in great demand - they can be installed in apartments. All models have a circulation pump. Wall-mounted versions can be with any type of chamber (except for Jaguars - they have a closed firebox). In turbo models, a standard 60/100 mm coaxial chimney is installed for smoke removal - it must be purchased additionally.

Advantages

A wide range of models, differing in parameters and design, can be selected for any area.
Affordable price - in comparison with German analogues.
High efficiency.
Availability of built-in boilers.
Adaptation to domestic conditions. Detailed Russian-language instructions.
Environmental friendliness - Protherm is installed even in children's and medical institutions.
Universal - can be used for heating residential and industrial premises.
Automation and self-diagnosis are the basis for comfortable use.

Principle of operation

For example, a wall-mounted 2-circuit turbocharged device “Gepard”. Works for heating and hot water supply. The water is heated in a plate-shaped steel heat exchanger. Combustion products formed during fuel combustion are discharged through a coaxial chimney. Oxygen comes as a result of forced injection - from the street. Monitoring and control is carried out using the display and buttons. On the screen – display of current parameters.

To improve the performance of a closed heating system, a circulation pump is connected. Thanks to the modulation burner, smooth adjustment of the heating of water and coolant is ensured. When you open a hot water tap, the power immediately increases and operating modes switch. When connected, parameters are configured, which can subsequently be changed automatically or adjusted mechanically.

Advantages of Protherm boilers for the home

To heat your home, you can use not only gas, but also diesel fuel. When today you need to purchase a boiler that runs on diesel, but in the future you plan to switch to gas heating, then it is not necessary to purchase two units, since Proterm heating boilers are available for sale.

Despite the fact that the models of this manufacturer have different power levels, this parameter compares them favorably with heating devices produced by competitors. The fact is that the Proterm gas boiler for heating a private house is capable of heating a building with an area of about 270 square meters.

In addition, all products from this Slovak company are characterized by simple and safe operation, as well as simple installation, since boilers of this brand comply with European and world standards.

All heating devices in the Proterm line are characterized by an unusual fuel combustion process. Even experts with extensive experience note its environmental friendliness.

When a Proterm boiler is made, low-temperature cast iron is used - a material that, when heated, minimizes heat loss as efficiently as possible.

Another advantage of these boilers is the presence of special regulators that allow you to independently create the most favorable microclimate in the premises of your home. Owners of a private house can change the heating power using a special temperature sensor. Since the above-described advantages that the Proterm heating boiler has are very significant, the choice of heating equipment by consumers is obvious.
