Advantages of boilers from ServiceGas

Automation makes the use of boilers of the Ulyanovsk plant comfortable. Heat consumers completely shift the task of maintaining a given mode to the electronics. Advantages of all modifications "Ochag":

• Economical gas consumption. The developers have provided a stabilizing device in the design - to equalize the fuel pressure. Thanks to the stabilizer, gas consumption is reduced by 30%.
• Environmental friendliness. Minimal emissions of harmful substances. In this respect, ServisGas equipment is not inferior to European counterparts, which is quite unusual for domestic gas equipment.
• Accuracy of temperature control.
• Three steps of safety:

- protection against unexpected extinction of the flame in the burner;

- shutdown in the absence of traction;

- protection against lack of gas in the system.

• Steel heat exchanger. High efficiency.
• Simple yet stylish design. Fits well into modern interiors, does not look like a foreign body, bulky and ugly.
• The design uses innovative technologies. High technical equipment.
• Low price. Simple and cheap service.
• No additional energy sources needed.
• Good build quality. Multilevel quality control.

Device

Their feature and advantage is the ability to adapt to any heating system. The user can:

• reinstall the front door, depending on the need - on the right or on the left;
• bring the coolant from the side convenient for it - from behind or from the side, thanks to two return lines.

Consists of constituent elements:

• hulls;
• automation;
• heat exchanger;
• the second circuit (provided that the boiler is double-circuit);
• security systems.

Construction in three parts:

• The lower part contains a combustion chamber, which is closed from the lateral and rear sides with a water jacket. Above the firebox there is a heat exchanger. Thanks to the flame tubes of the latter, the efficiency of heat transfer and heat exchange between the exhaust gases and water is ensured.
• The upper part contains a fume extractor and a built-in draft stabilizer.
• The middle part has a baffle that ensures stable operation regardless of the ambient temperature.

The tandem of the smoke extractor and the heat exchanger makes the boiler intellectually self-sufficient - it can function without any consumer intervention, without the need for manual adjustments. Stability of work in case of unstable thrust is provided by the stabilizer thrust.

In the firebox there is a burner manufactured by ServiceGas. Components - front panel, burner pipes, safety sensors - flame and draft, control unit SABK AT. Under the pipes there is a lattice damper supplying secondary air to the burner.

Important! The installation of the device in the room should be carried out with free air access through the lower part of the device to the burner pipes.

How to ignite?

The sequence of ignition is carried out by turning the control knob clockwise. Further procedure:

• You need to turn the knob until the mark is directed to the pointer.
• Then press and hold the "Start" button.
• The piezo ignition button must be pressed until it clicks. The pilot ignites.
• Keep "Start" pressed - waiting for the thermocouple to warm up. On the igniter, the gas block operates in auto mode.
• Turn the knob counterclockwise to the required temperature.

Immergas S.p.A

Immergas S.p.A - no more than 1000 employees and 2 assembly plants (in Italy and Slovakia). With such a base, the Italian manufacturer has been supplying gas boilers to 43 countries of the world since 2002. The competitiveness of products in the Russian Federation is explained by the combination of a long (declared 10 years) service life and low gas consumption. For convection models, efficiency is achieved by increasing the area of ​​the heat exchanger and automatic preparation of the gas-air mixture. Condensing boilers have an improved heat extraction scheme and more functions. The equipment is not demanding on the characteristics of the water and gas supply. The manufacturer gives a 1 year warranty for each model. A network of service centers located in more than 100 Russian cities is responsible for the maintenance of boilers.

How to choose?

Options for the material for the manufacture of a heat exchanger - a container where the heat carrier is heated:

• Steel. Good ductility minimizing thermal stress cracking. Used in budget models. Service life is short - due to susceptibility to corrosion.
• Cast iron. Great weight. They are more expensive than steel ones. Minus - they react to temperature changes. They do not rust - a plus. They serve for about half a century.
• Copper. They weigh little. Resistant to corrosion. They are usually found in wall-mounted versions.

Trust but verify

There is an opinion about the logic of choosing time-tested equipment. But, under the brand name of each brand, both improved "classics" and fundamentally new models appear. The idea that it is justified to purchase the most budget models from renowned manufacturers does not stand up to criticism either. Without proportional consideration of the serviced area (with water points) and the declared potential of the heating boiler, it is impossible to make the right decision. Analysis of problem situations, in 80% of cases, reveals errors in the selection and operation of heating devices.

Designations

When designating heating devices, an alphabetic abbreviation is used. Each letter contains specific information:

• K - boiler.
• D - the set includes gas-burning equipment.
• T - can be used as a solid fuel.
• C - steel.
• M - installation of heating elements and an extended firebox is provided.
• B - there is a water heater.

Knowing the meaning of the letters, the user by the abbreviation can decipher the basic information about the proposed options.
