Overview of Wolf gas boilers

Thanks to the Wolf gas boiler, the problem of space heating is solved. German technology keeps the quality bar, fully meeting the expectations of consumers, moreover, equipment for autonomous heating systems is considered the best in the world, and the Wolf brand is a clear confirmation of this.

About company. Wolf GmbH is a German company founded in 1963. It became the first owner of the ISO 9001 certificate in its segment. It specializes in climate technology, the main share of which is hot water boilers. The brand introduced the first wall-mounted units in 1994, and in 2005, high-performance condensing models were released – a new word in the field of heating equipment.

The range of gas boilers “Wolf”

Wolf offers gas heaters in various capacities. Low-power are designed for heating housing: houses and apartments. Units of medium and high power – for heating industrial buildings.

Varieties:

  • Condensing wall type – FGB and CGB-2 series;
  • Classic wall-mounted, differing in the design of combustion chambers – atmospheric and turbocharged. Comfort Line – CGU-2, CGG-2;
  • Floor. Function Line Series – FNG and NG-31E.

The manufacturer also offers combined models CGG-1K, condensing series CGS (floor), CGW, CGB and CGB-K (wall). The Function Line and Comfort lines differ in design, the presence of additional options.

The most demanded model

In the CIS countries, the Wolf CGG 1k 24 modification is the most popular. Design features, specifications:

  • Thanks to a well-thought-out layout and high-quality materials, the CGG 1k 24 is quite reliable and has a high efficiency;
  • Convenient design makes installation of equipment extremely simple. There are no problems with access to working nodes;
  • There is no need for free space near the side walls – thanks to the insulation, there is no heat exchange with the space.
  • In the event of a problem, there is the possibility of computer diagnostics;
  • Extremely simple control is carried out by a computerized unit and special software;
  • Flare burner controls the intensity, stability of the flame. The ignition of the burner is electronic. This allows you to save fuel;
  • The boiler can operate on various types of gas;
  • The model has a closed firebox, the air for gas combustion comes from the street;
  • Thanks to a powerful circulation pump, the coolant flows freely through the system;
  • Due to the lamellar structure of the heat exchanger, heat losses are minimized;
  • Due to the programmer, you can program the operating mode for the day ahead;
  • The power of the device is 24 kW. This is enough to heat the area of ​​most apartments and houses, which is about 70% of all housing;
  • Heating and hot water are independent of each other. The water gets hot in seconds thanks to the quick start system;
  • All combustion products are discharged to the street through a turbocharged chimney.

How much are

The products of the German concern are quite accessible to the Russian consumer. The price of an average Wolf boiler is 70-100 thousand rubles. The cost depends on the power and design. The most expensive wall-mounted boilers are condensing.

Features of operation and management

Double-circuit boilers combine two functions. It is convenient and profitable, besides their price is relatively low. It happens that they are used even in houses with a centralized water supply – it turns out to be more profitable than paying bills for hot water consumption.

Both floor and wall-mounted boilers are convenient and reliable. The method of installation does not affect their operation and characteristics in any way. Mounted units are more compact, and floor-mounted units have greater heat output.

Despite the wide functionality, Wolf boilers have extremely simple, intuitive controls. It is not difficult to understand its nuances, but if some points are not clear, there is an instruction in which everything is described in detail. Adjusting the parameters allows you to choose the optimal mode – modern gas appliances maintain the temperature set by the user themselves, without requiring constant attention. Its stability is maintained by a thermostat – it is connected to a sensor located in a heated room.

Automatic system control

All modern heaters, including Wolf, automatically maintain a comfortable temperature even in the absence of the owners. Despite the multi-stage security system and automation, the device needs to be controlled by third parties – neighbors or relatives. If, for example, an emergency shutdown occurs, the heating system may fail. There are many reasons for shutdown:

  • The voltage in the network has dropped;
  • The electricity was turned off;
  • The section of the chimney has decreased due to ice;
  • The gas pressure has dropped;
  • The torch went out because of the wind.

In each of these situations, certain actions must be taken.

Maintenance and service

Any gas equipment requires regular service, namely:

  • Troubleshooting;
  • Checking the level of gas pressure, voltage in the network;
  • Cleaning the burner and chamber;
  • Checking the system for tightness;
  • Automatic adjustment;
  • Setting burners.

Reviews

CGG-1K 24: Viktor E., Togliatti

I doubted my choice. Little has been heard about this brand, there is practically no advertising. Satisfied with the work. Simple, economical, quiet operation. Inside, on each device, there are stickers that indicate the number, the country of manufacture. I recommend buying a single-circuit apparatus with a boiler in addition. Regardless of the pressure in the pipes and the number of open taps, there is always stable hot water. The boiler recirculation works – so you do not need to wait until cold water runs through. I have a 110 l boiler – you can take a bath, and there is no cooling, as the water is rapidly warming up.

CGG-1K 24: Natalia G., Engels

There are no benefits. Service too. After a year of installation, the boiler remains unconfigured. At a minimum, the water is heated to 55 degrees – not even suitable for washing dishes, not just for bathing and showering. The service department set up – according to the heating area. At first the water was too hot, the master called – they reconfigured it several times. As a result, once again they could not connect the module and turned to the importer. So far the issue has not been resolved.

Wolf heaters — one of the best in the world market. Thanks to the variety of models and a wide range of capacities, each consumer can find the right option for their needs. Among other things, the company can change the configuration at the request of the client.
