Overview of gas boilers Immergaz

The Immergaz gas boiler is a product of the Italian company of the same name, specializing in the production of wall-mounted double-circuit models. These are reliable devices with a stylish design, for which the manufacturer provides a five-year warranty.

IMMERGAS was founded in 1954. Its slogan is “Two hundred heating horses”. The company promotes the latest technologies, focusing on efficiency and reliability. The model range of mounted devices includes more than 8 dozen modifications. Immergaz’s products are not as widely represented on the Russian market as its competitors Baxi and Ferroli. A limited number of models are supplied to Russia: only those that are adapted to local climatic conditions. That is why there are very few reviews of Immergas products on the net.

Advantages and disadvantages of Immergaz boilers

Pros

  • Compactness. A wall-mounted unit always takes up less space than a floor-standing unit. Does not need a separate room. It fits easily in the kitchen or in a room that meets the requirements for rooms in which gas equipment is installed.
  • Multifunctionality. Italian devices are able to function autonomously, without requiring regular user intervention, they fully control their work.
  • High quality assembly, components, materials.
  • Minimum noise during operation.
  • Availability of service in the regions.
  • Positive feedback from experts.

Cons

  • Price. Equipment assembled in Italian factories is quite expensive.
  • The cost of spare parts. Many components and parts need to be ordered and expected delivery.
  • Inconvenient control – pressing the buttons, you have to make an effort.
  • Response to power surges. The need to purchase a voltage stabilizer.
  • The chimney is not included in the kit, it is bought separately.

What is special about them

Immergaz products are not cheap, but if we correlate the positions in the price-quality formula, this is exactly the option that many people need. The manufacturer offers:

  • Single and double circuit versions.
  • Single-circuit with built-in boiler 40/60 l.
  • Classic and condensation.
  • With open (atmospheric) and closed (turbocharged) furnace.

Condensing machines scare away high prices. Gas in the Russian Federation is cheap, and the main advantage of condensing versions is high efficiency. Fuel savings of 20–30% are not very attractive to our customers, so few people are willing to overpay for a gas boiler. But in Europe, where gas is hundreds of percent more expensive, “condensate tanks” are very popular.

What does Immergaz offer?

Single circuit boilers Nike Mini X 3E and Eolo Mini X 3E only heat the house, they are not designed to heat hot water. The cost of single-circuit versions is slightly lower than double-circuit ones. The first ones cost between 30–000 rubles, with two circuits – 35–000 rubles. The price depends on the power of the equipment and its efficiency.

Dual-circuit options are in high demand: users are attracted by the possibility of providing domestic hot water. At the same time, all single-circuit modifications involve the connection of an BKN (indirect heating boiler).

Eolo series – double-circuit with a closed chamber:

  • “Eolo mini”. two heat exchangers.
  • “Eolo Star”. One bithermic.

Nike Open Fire Series:

  • Nike Mini 24 E. Two separate heat exchangers.
  • Nike Star 24 3R. One copper bithermic.

The Star series has one bithermic heat exchanger, while Nike has two separate ones. One of copper works for heating, the second of stainless steel – for hot water supply (DHW).

Installation and operation

In order for the Italian gas equipment to work properly and smoothly, it must be installed by specialists. They also carry out the setup and the first launch. The device must correspond to the heated area. Each device is accompanied by instructions with a detailed description of the installation process. How to mount a hinged boiler:

  • The device is attached to the wall.
  • They make the grounding of the device – it will protect it during thunderstorms, and connect it to the mains.
  • Install the expansion tank. If forced circulation of the coolant is provided, a pump is installed.
  • Connect to the heating system.
  • They test the system for leaks, this process is described in the instructions.
  • Remove oxygen accumulated in the pipes.
  • When the connection is completed, the first run is performed.

Устройство

Design features:

  • All modifications are equipped with circulation pumps Grundfos (Denmark) – they provide the movement of the coolant, and a gas valve SIT (Italy).
  • The supply pipes (gas and water) are copper.
  • There is an expansion tank of 6 liters.
  • Equipped with a digital screen that displays the set settings – the user can monitor the temperature, pressure, winter / summer mode. It also displays error codes that notify the user of malfunctions.
  • All modifications have NTS temperature sensors, draft sensors and overheating protection sensors.
  • If desired, a remote thermostat is connected, a simple mechanical or “intelligent” one, which allows you to program the operating mode for a week in advance.

All models are equipped with:

  • pump anti-blocking;
  • anti-blocking three-way valve;
  • frost protection.

The principle of operation of Immergas boilers is quite simple, and their management does not require special knowledge. The display shows all information about settings and errors.

How to choose a boiler “Immergaz”

When choosing a wall-mounted double-circuit boiler, the buyer needs to decide on the following points:

  • Power – it is selected based on the heated area. Usually for every 10 m² there is 1000 watts.
  • Type of combustion chamber – open or closed. For apartments, turbocharged versions with a closed firebox are more suitable.
  • The number of contours. Take only for heating, you need one circuit; if you want hot water – two circuits.
  • The method of removing exhaust gases is forced or natural. Forced draft is more suitable for apartment owners, you just need to buy a coaxial pipe. Residents of private houses can install natural draft models, but they need to equip a chimney.
  • Heat exchanger design. The most practical option is two separate heat exchangers. This option allows you to heat water faster and save gas. The secondary plate-type heat exchanger ensures uniform heating of water and avoids overheating.

Reviews

EOLO Star 23kw: Rodion G., Suzdal

Posted two years ago. Before buying, I learned a maximum of information about this manufacturer, or rather, about its products. My apartment is 75 square meters. Heats well, gas consumption is moderate. Water heating is instantaneous, even at low pressure. The temperature of hot water can be set to the nearest degree. Simple control, you just need to set it up correctly, and then everything is monitored by automation. Protected from power surges. Almost silent. Of the minuses – there was a failure to set the temperature of the radiators.

EOLO Mini 24kW: Ilya T., Urjum

Easy installation. Wall. The front cover can be easily removed to clean the burners. Does not heat up during operation, there is a digital interface. I like the self-diagnosis system, all problems are easily deciphered by error codes. The only downside is it’s expensive.

Immergaz boilers have earned the right to be the best among Italian competitors and one of the best on the European market. This is a reliable gas equipment, equipped with the latest technology and adapted to Russian conditions. The company supplies the domestic market with the models most in demand among ordinary consumers – wall-mounted heaters with a DHW circuit, designed for heating houses and apartments.
