Gas boilers from Immergas

Immergas was established over fifty years ago in Italy. Over the course of its operations, the company has created a number of gas boiler models that are distinguished by their performance, compact design, and high efficiency.

We started with the most popular contemporary designs, added our own modifications, strengthened certain areas, and improved the strength and functionality of the most important parts.

Consequently, several model lines that can operate in challenging environments and carry out designated tasks even in the presence of unstable power, gas, and water supplies have been acquired.

Presently, Slovakia is home to factories making equipment for Russia and Eastern European nations, while Italy is the primary location for Immergas boiler production. This move has greatly enhanced logistics and lowered retail prices.

Kinds

Immergas provides a comprehensive list of all available design and functionality options to its clients.

Different kinds of gas boilers can be conditionally combined based on different requirements.

According to the mode of execution:

• Wall mounted. Installed on strong load-bearing walls, they are compact, small in size and limited in power.
• Floor-standing. Installed directly on the floor or on a special stand. May have increased strength, power and size.

In terms of feature set:

• Single-circuit. Designed only for heating the coolant (heating the house). However, most models can be connected to an external indirect heating boiler, which significantly expands the capabilities and allows you to increase the functionality of the equipment to the maximum.
• Dual-circuit. Capable of simultaneously heating the coolant for the heating system and preparing hot water for domestic needs.

According to the kind of heat transfer:

• Convection. Heat transfer is carried out in a standard way – from the flame of a gas burner.
• Condensation. The coolant is preheated from the energy obtained from the condensation of water vapor from the exhaust smoke. Increasing the temperature allows you to reduce gas consumption, make the heating mode softer, which increases the service life of the heat exchanger and burner.

Crucial! Condensing boilers cost two to three times as much as conventional models, but they can only operate to their full potential on low-temperature heating systems, like underfloor heating, and with an air temperature differential of no more than twenty degrees between the outside and inside of the room—conditions that are unfeasible in Russia.

According to the kind of combustion chamber:

• Atmospheric. Combustion air is taken directly from the room, smoke is removed using natural draft.
• Turbocharged. The combustion chamber is sealed, air is supplied and flue gases are removed using a turbocharger fan.

Another division is made based on the kind of heat exchanger:

• Separate (primary – copper, for heating the coolant, secondary – stainless steel plate, for preparing hot water).
• Bithermal (combined). Made according to the "pipe in pipe" principle, simultaneously heats the heating medium and hot water.

The user’s desires and preferences dictate which particular model they choose.

Series and models related to them

There are various series in the Immergas boiler lineup.

Boilers installed on walls:

• Nike. The series consists of several lines Mythos, Star and Mini. Dual-circuit models with a capacity of 24 and 28 kW. The Star line is equipped with a bithermal heat exchanger, which automatically increases the requirements for water quality. The remaining lines have a standard separate type of heat exchanger. Burner type – atmospheric, with natural draft of the furnace type.
• Eolo. There are Mini (separate heat exchanger) and Star (bithermic heat exchanger) lines. Turbocharged combustion chamber, dual-circuit design allows for heating and hot water supply.
• Avio/Zeus. A series of gas boilers with an integrated 60 liter water boiler. They are distinguished by their increased dimensions and ensure an uninterrupted supply of hot water in any quantity.
• Maior. Increased power boilers 24-32 kW. Double-circuit models with turbocharged burner.
• Victrix Pro. Professional series of gas boilers with a maximum power of 120 kW. Capable of cascading with a total power of 600 kW.

Series of floor-standing boilers:

• Hercules. Double-circuit boiler with a power of 32 kW with an integrated tank of 120 l.
• Ares. Single-circuit boilers with a power of 22-60 kW.

Let’s look at the most widely used Immergas gas boiler model, the 24 kW Eolo. The Eolo Mythos and Eolo Star units are part of this group. The kind of heat exchanger separates them from one another.

Mythos line models feature a separate heat exchanger, which improves dependability and slightly lowers water quality requirements.

Because lime deposits form quickly, the bithermic heat exchanger in the Star line is susceptible to hard water.

On the other hand, the absence of a three-way valve in this line lowers the unit’s failure risk and boosts its dependability.

Other than that, sales data confirm that the boilers are identical.

Device

There are not many differences between the general layout of modern heating units and the design of Immergas gas boilers.

The primary heat exchanger and burner are the key components that work together to heat the coolant (HC).

After exiting it, the heated liquid enters the secondary plate heat exchanger, which is used to prepare hot water (DHW).

The coolant then passes through the three-way valve, where it is released into the heating circuit after reaching the temperature determined by the settings.

A circulation pump drives the OV’s movement, and turbofans handle both the air supply and smoke exhaust.

A control board with a sensor system (self-diagnosis) keeps an eye on how each boiler system is operating.

They alert the owner right away to any malfunctions or failures by constantly checking the state of important components and assemblies.

Every detail you require to understand these heating systems is covered in our comprehensive guide on "Immergas Gas Boilers."
