Gas boilers heating vilant: detailed product description

It is noteworthy that gas coppers of heating VAILLANT completely correspond to their name, because this expression is translated from French as valiant or heroic, but the company name uses two words from different languages ​​- French and English - VAILLANT GROUP, which can be translated as a valiant group.

Such a multilingual phrase that defines the name of a company is quite justified, but more on that below. In addition, we will pay attention to the manufacturer’s products, which have proven themselves excellently all over the world, and watch a video clip on this topic.

VAILLANT

About company

In the European production gas boilers VAYLANT take second place and this is not for nothing - the VAILLANT GROUP company has been on the market for 140 years and is very well acquainted with the demand and needs of customers. The production and research centers of this organization operate and flourish in Germany and in France, Spain and Italy, Slovakia and Great Britain, China * and Turkey.

Subsidiaries have settled in more than 20 countries of the entire miter, and products of this manufacturer are exported more than in 60 countries.

*Note. Products manufactured in the PRC are intended exclusively for this region and are not supplied to the European market.

If we talk about gas boilers, then you can buy them in retail stores in the Russian Federation. At the same time, they will differ not only in power, but also in the method of installation - on the wall (suspended) or on the floor (floor); they can be either single-circuit or double-circuit heating boilers. In addition, there are differences on the principle of heating the coolant - convection and condensation, but we will tell you about this below.

Of course, the company owes such popularity not only to the production of gas boilers - these are a variety of energy-saving systems, such as heat pumps, using the thermal energy of the Earth, solar installations powered by solar energy or hybrid systems that work with any equipment for heating.

Note! You should know that the branch of VAILLANT GROUP in Russia LLC Vayant Group Rus has about 50 wholesale outlets across the country, but not a single online store that sells retail. Consequently, if you find VAYLANT heating boilers in Russian online stores, then this is either a fake or a direct fraud.

Examples of convection boilers

VAILLANT atmoTEC plus VU single-circuit heating gas boilers are an excellent solution for those who do not have to connect a hot water supply system (DHW). The modulation of the power of this model, depending on the modification, can be either 9.6-24.0 kW or 10.9-28.0 kW, although in any case it is regulated by a modulating burner, there is an integrated three-way valve.

Both one and the other variant is equipped with a copper heat exchanger (this is the best material for such an appliance), it is possible to connect indirect heating to the boiler.

The model atmoTEC pro, turboTEC pro has a built-in DHW circuit, a vent (natural) for gas combustion products into the atmoTEC chimney, and a turbocharged turboTEC duct for exhaust gases. Modulation of the power of this model, depending on the modification, can be either 9.6-24.0 kW or 8.1-24.0 kW, although in any case it is regulated by a modulating burner, there is an integrated three-way valve.

Both one and the other variant is equipped with a copper heat exchanger (this is the best material for such an instrument), it is possible to automatically switch to the DHW function mode at a flow rate of 1.5 l / min (with less consumption, the burner does not turn on - so says the operating instructions ).

Examples of condensing boilers

Condensing gas heating boilers VAILLANT ecoTEC plus VU OE has a lot of power, depending on the modification it can be 80 kW, 100 kW and 120 kW, with a heat exchanger capacity of up to 24 liters - this model has a heat exchanger design characterized by low hydraulic resistance.

The modulation of the burner allows you to vary the power of the unit from 20% to 100%, which means that such a heater is excellent for both high-temperature and low-temperature circuits, or both. The average level of efficiency for this modification is 109%.

The condensing gas heating boiler VAILLANT ecoCOMPACT has an average capacity, depending on the modification, it can be 19 kW, 24 kW and 30 kW, with an expansion tank capacity of 12 liters (the unit price is less).

Modulating the burner allows you to vary the power of the unit from z0% to 100%, which means that such a heater is excellent for both high-temperature and low-temperature circuits, or both at once. The average level of efficiency for this modification is 109%.

The main differences between convection and condensation gas boilers

• Natural or bottled (liquefied) gas flows to the burner, where, burning, heats the heat exchanger, and the combustion products are removed by natural or forced means.. The optimum mode of operation is in the range of 60-80? C, since the point of condensate formation is 55-57? C and regimes with a lower temperature adversely affect the heat exchanger (acid steam destroys the walls).

• In condensation units, heat from the combustion chamber (its temperature reaches 150? C) is not displayed outside, but is used for secondary heating, until it reaches the critical point of condensate 55? C. Acidic condensate is discharged from the chamber through a special channel, where it is filtered and only then discharged.

Conclusion

In conclusion, I would like to say that if you make a heating circuit and mount the boiler with your own hands, then after that you must invite a specialist with a license for an examination. This will allow you to have a starting point for the warranty period from the moment of installation, and not from the date of sale of the unit by the store.
