Gas boilers Immergas: design features, range and recommendations for use

The Italian manufacturer Immergas has its plants in 15 countries. Gas boilers of this famous manufacturer are sold throughout Europe, and he also has Russian representative offices. The Immergas company produces boilers of the “new generation” - condensing. They use not only heat that is released from gas combustion, but also heat from steam. This means that fuel costs are reduced by almost 35%.

You can find about 80 models of Immergas products, but not all of them are delivered to our country, but only those that are adapted to domestic climatic conditions. About them will be discussed in our article.

Products from Immergas has always been focused on its pricing policy for any man in the street.From an extensive range, you can easily pick up both economy-class products and technologically advanced boilers at a higher cost.

The design consists of such units and parts as:

• gas burner with electric ignition;
• circulation pump from Grandphos;
• bypass (to protect the heat exchanger from overheating);
• reed sensor (to measure the temperature of the coolant);
• the “anti-freezing” mode (when the temperature drops to 4 degrees, the product will automatically start, after which it will be constantly maintained at 40 degrees);
• outdoor thermostat.

The latter have the highest efficiency of 100%. The company manufactures products with both one and two circuits. If you just need to warm your dwelling from time to time, a single-loop variant will suit for this purpose. If, in addition to heating the building, you also need to heat up the liquid for domestic needs, then you can purchase a dual circuit unit. Combustion chambers in products can be either open or closed.

Some elements for boilers are produced only in enterprises located in Italy. This, for example, is a boiler for water accumulation, in which the heat exchanger and the pipeline of the device are located.

Because of its convenient parameters and low weight, these products are easily placed in a small kitchen. For Immergas equipment, you do not have to allocate a separate room for installation.

Each device has a heat exchanger with either natural or forced circulation type. If you sometimes leave home, then it is better to opt for a design with circulation of a forced type, because such a system will be able to work independently without any problems.

They can connect the control system using the remote. So using the units will be much easier. High-quality technical characteristics of any product will allow you to easily select exactly the boiler model that will fit most perfectly into your heating system.

Immergas wall products do not connect to the chimney. A coaxial pipe is connected to them so that it removes all the combustion products through a special wall hole.

When choosing a gas device Immergas, be sure to specify the methods of heating water, as they can be carried out:

• in the usual scheme with two circuits, but without the use of a boiler;
• according to the scheme with a boiler;
• according to the scheme with an external type water heater.

In some samples that work in the usual way, the Aqua Celeris system is used. It guarantees a quick supply of heated water when needed.

Gas units from Immergas have strapping. They contain pumps for circulating water, safety valves and expansion tanks. Some products have special tanks for long-term preservation of heated water. In some models, there is a whole speed control system using frequency modulation to reduce fuel consumption for operating a home heating system.

In products Immergas can be found:

• weather-dependent automation (it will control the microclimate of the dwelling depending on the outdoor weather);
• independent type of contours (in products that will have rather high power);
• automatic equipment called Superior (it will make control of boilers easier);
• increased heat exchangers (they do not allow clogging);
• remote control systems.

The main advantages of Immergas heating equipment:
