Gas boilers Viessmann. Specifications and customer reviews

The manufacturer Viessmann focuses its activity on manufacturing of engineering and communication equipment intended for supplying target objects with water, steam, heat, etc. Boiler installations of this brand can be called universal, although in this line there is a clear segmentation of the units. Supporting the tradition of manufacturing industrial power systems, the company does not forget about the introduction of new technologies. In modern design, Viessmann gas boilers not only provide high performance, but also are easy to operate. And this is also an incomplete list of qualities that German boilers have on gas fuels.

General information about Viessmann gas boilers

Under the Viessmann brand, gas equipment with various technical and operational qualities, designs and designation is on the market. Most models belong to hot water units, among which there are many condensing versions. In this category, Viessmann gas boilers are provided, which have high efficiency, wide functionality and optimum heat conductivity. At the same time, the company also offers unique optional features. In particular, the proprietary technology of MatriX provides for equipping the structures with special burners with a heat mesh made of a special alloy. This device maintains the stability of the basic function regardless of the temperature effects.

In addition, German boilers differ in the way they are installed. In the line, you can find small wall units, as well as gas boilers Viessmann for floor installation. The first are suitable for domestic use, and the second can provide separate boiler houses that serve industrial or administrative buildings.

Main technical characteristics

In choosing a model of a gas boiler for various needs, it is necessary to determine the requirements for its capabilities. The main indicator of the level of efficiency of such equipment is power. In general, according to the ruler, it varies on average from 2 to 1,400 kW. But this does not mean that one Viessmann gas boiler can cover such a wide range. Depending on the model, gradual gradation occurs with ranges of indicators. For example, there are modifications that have a potential of 2 to 80 kW. The most powerful installation provides a thermal return in the spectrum of 800-1400 kW.

Next, take into account the efficiency. The higher this indicator, the more efficient and economically more profitable the system will be. On average, the efficiency of German models is 90-94%, which is not bad compared to competitive products, but in some versions this value reaches 98% - again, thanks to the MatriX burner. No less important is the consumption of natural gas, on the basis of which such units operate. On average, Viessmann gas boilers consume 3-8 m ³ / h. Individual modifications consume fuel volumes that go beyond the specified range.

Reviews of models Vitopend

A fairly popular line of gas boiler systems, which combines environmental friendliness, functionality and performance. The users themselves point to a successful implementation of electronic control, the panel of which is located at the bottom of the unit. By the way, the Viessmann Vitopend 100 gas boiler assumes a wall installation, which facilitates the maintenance of the unit. This model is also equipped with a burner with electronic modulation. In practice, this means more precise adjustment of the characteristics of the heating circuit. If necessary, the boiler can be used in the operating automatic mode. According to the owners, the operation of the system is stable, and in case of failures it is possible to rely on the diagnostic function.

Reviews about the model Vitogas

If a boiler model is required to serve a private homeowner, it makes sense to consider this option. In particular, the gas boiler Viessmann 100-F GW2 due to the power of 72 kW is able to provide warmth for country cottages of a large area. Owners of the unit note its reliability, economical fuel consumption and a high level of safety. As in the case of the Vitopend family, representatives of this line are equipped with a panel with digital control, which facilitates the convenience of keeping the boiler. But special attention was paid to reliability requirements, since gas equipment is traditionally considered to be the most dangerous. As noted by users, the design is provided with high-strength heating surfaces made of gray cast iron, which are flanked by flake graphite.

Comments about Vitorond model

The Vitorond model has a capacity of 80 kW. Users indicate the efficiency of this unit as the main heating system. In many respects this is achieved due to the special design of the cast-iron heat exchanger, which makes it possible to ensure a uniform distribution of thermal radiation. Like the gas boiler Viessmann Vitopend, this model is safe, from the point of view of ecology, which is also appreciated by the owners of country houses. Complete combustion of fuel provides not only high performance, but also reduces the emission of harmful substances. Many users also operate this boiler as a heating system for water. True, for a full-fledged use of the model in this capacity, it is necessary to separately purchase a water-heating tank.

Conclusion

The German manufacturer is well known for utilities and specialized enterprises that work with industrial equipment. In the company's assortment you can find the Viessmann gas boiler for both public utilities and private needs. In both cases, the products will have a high working life, wide functional content and ergonomic controls. The main thing is to initially calculate the power requirements and evaluate the possibilities for installing the equipment. By the way, the assembly of units includes wide sets of additional accessories that will facilitate both installation work and further maintenance.
