About the manufacturer

After more than 40 years of manufacturing heating equipment, WOLF GmbH has become known as a reputable and high-quality German brand. Under the name Wolf Energy Saving Systems Ltd., the business is represented in the Russian market. Boiler purchases were made at your own risk not too long ago because the only places to find installation and maintenance professionals were in Moscow. On the other hand, the service structure has evolved so quickly in recent years that you can now rely on high-quality service in vast areas. In general, a lot of people frequently comment on how well the hot line works.

This brand’s gas boilers are known for their classic design and closed combustion chamber, which minimizes problems. Modulating burners and copper heat exchangers. While more expensive models almost silently operate, more affordable models produce some noise. Every model has automation with auto-diagnostics and all the contemporary safety features, like water filtering, auto-ignition, circulation pump stopping, and protection against freezing and overheating.

The absence of a programmer is a well-known drawback of practically the whole model range, which is typical of analogs in this price range. Although most boilers only support control via the eBus protocol, there is always the option to connect external control. This implies that the control unit should only be purchased from reputable retailers at a high price that not all customers can afford.

Although voltage fluctuations do not affect Wolf boilers, it is still advisable to connect them through a voltage stabilizer. In the event of a breakdown, voltage fluctuations typically cause the electronic board to fail. If not, all gas models can be considered virtually trouble-free; compared to many of their analogs, there are very few instances of service calls. Even the budget models are fairly expensive, but this is standard for any manufacturer’s boiler in this category.

Reviews of owners about gas boilers Wolf: advantages and disadvantages

Since it is impossible to generalize across the entire model range, many features are model-dependent. However, we have outlined the general benefits and drawbacks that apply to each model after examining installation and operation experiences as well as a number of owner reviews.

The best and most famous models: characteristics and prices

Wall-mounted

FGG-K-24

The least expensive model in the gas boiler lineup and one of the best-performing models overall. This boiler has a closed combustion chamber and is a two-circuit convection boiler. Copper serves as the main heat exchanger because it is more heat-conductive and resistant to corrosion. 2.1 m 3 of gas can flow per hour at maximum. featuring an integrated expansion tank. The average DHW circuit capacity of 11.4 l/min is sufficient for two to three points of consumption.

The manufacturer declares stable operation at a voltage drop in the network up to 160 V and pressure in the DHW circuit up to 0.5 bar. However, problems with electronic board breakdowns do occur. Also, in severe frosts, the boiler often displays error E51, which indicates insufficient draught. This is most often caused by ice on the chimney headband. This is the only boiler in the Wolf lineup that works with the OpenTherm protocol, with which most third-party room thermostats work. Perhaps the only disadvantage, apart from the lack of a built-in programmer, is the limited choice of capacity. The model is available only in a version with a heat output of 24 kW.

How to pick a room thermostat to reduce your monthly heating expenses by up to 30%

CGG-1K

Its construction is nearly identical to that of the FGG-K, with a few minor differences. First off, there are new controls, a 2 liter larger expansion tank, marginally bigger dimensions, and quieter operation. Second, working with liquefied gas in addition to natural gas is feasible. Thirdly, there is a version that has a capacity of 28 kW in addition to 24 kW. Among the few models that are assembled directly in Germany is this one.

Other than that, it is a closed combustion chamber gas boiler that is mounted on a two-circuit system. But given that it costs nearly twice as much, we believe this model is not the best option and is not as good as other models in the Wolf gas boiler line in terms of "price-quality."

FGB

Gas boiler with closed combustion chamber that operates on a single circuit and condenses. The additional heat extraction from the waste gas condensate implied by the condensing principle of operation greatly boosts efficiency (but also increases the cost of the design). Models with the prefix "K" have an efficiency of 100%, a copper primary heat exchanger, and the ability to operate with both natural and liquefied gas. The boiler is spared the well-known issue of poor draught caused by ice on the chimney because the condensing principle of operation prevents it from forming at lower temperatures of the exhaust gases.

The boiler has a water filter and all the contemporary safety features. When an optional interface module is present, smartphone control is possible. There are no drawbacks to the boiler other than its price. The ignition electrode’s failure is the only known issue, so the boiler needs to be cleaned and maintained on a regular basis. available in versions of 24, 28, and 35 kW.

Every aspect of condensing gas boiler operation and selection criteria

CGG-3K

One of the greatest gas boilers Wolf for heating a private residence is the most advanced two-circuit model from the third generation. Its high efficiency—92,2% efficiency factor—is what makes it stand out. This is a very unique technology where the return line is cooled with coolant to minimize wear and tear. The heat exchanger is copper, and the burner is modulating and water-cooled. Generally speaking, the boiler’s design prioritizes the most resource-efficient and gentle mode of operation. Nevertheless, there are no statistical data on reliability available due to the novelty of the model.

DHW capacity is 11.7 l/min, which is above the market average. Owners often note absolutely silent operation of the boiler (only 38 dB, which is quieter than the average air conditioner or fan). From the disadvantages, again, in the basic set lacks an important programmer, which is available in many analogues of this price segment. The organization of programming the boiler operation for the next day or week, as well as weather-dependent control is realized only through the proprietary module Link Pro, the cost of which is about 30 thousand. rubles. During the years of presence on the market no serious service calls are known. Also an advantage is the availability of a low-power version with an output of 18 kW. In total, the boiler is available in versions with heat output: 18, 24 and 28 kW.

Floor standing

MGK-2

Wolf currently offers a limited selection of floor standing gas boilers, with this model being the only standout option. The condensing single-circuit MGK-2 is intended for heating large homes or businesses because its least heat-producing version has a power of 130 kW. The boiler’s construction is optimized for maximum resource utilization, featuring a closed combustion chamber, aluminum-silicon durable heat exchanger, and a modulating burner with a 17% range. Working pressure allowed is 6 bar; liquefied and natural gas can both be used.

You can use a smartphone to operate the boiler in its basic configuration thanks to automation, which includes auto ignition and all safety features. Installers observe how simple it is to control multiple boilers from a single unit and combine them in a cascade. It is noteworthy that the large capacity is operated in an almost silent and quiet manner. available in models with 130–1000 kW of heat output.

Starting price: 490 000 rubles.

Known faults of boilers Wolf

The number and frequency of failures are the same for Premium boilers as they still occur over time. The control board, ignition electrode, and turbine are the most common failures, based on statistics from service calls. It is important to think about the most common malfunctions separately, which aren’t always related to a breakdown:

First and foremost, one must inspect the system for leaks (in the boiler interior as well as all communications) if the pressure in the heating circuit drops. The front panel must be removed in order to inspect the boiler inside. The heat exchanger, three-way valve, and all connections need to be examined closely. The most frequent error code indicates a potential leak in the make-up tap.

Every potential reason why home gas boilers’ water pressure might decrease

First things first, make sure the water filter is clear and the heating system taps are open if the boiler does not respond in any way when turned on. In most cases, the boiler’s indicator flashes green when one of these reasons happens. When a flow sensor fails, which is the most frequent cause of failure, the indicator typically flashes red. Less frequently, a voltage drop could cause the entire control board to fail.

The most frequent error codes

Every model of Wolf gas boiler has an auto-diagnostic feature and up to 70 error codes, allowing you to quickly and precisely identify the problem.

Insufficient air movement. The most common cause of the issue is icing of the chimney headband; this can be fixed by carefully clearing the ice and then taking additional care of the chimney’s insulation. In many cases, resetting the boiler also helps. If the issue persists, the turbine (clogging, damaged blades) or pneumorelay (thrust sensor) are the most likely culprits.

Issues with the ignition of the burner. The most typical issue is an ignition electrode that has failed or become clogged. Prior to anything else, though, you should confirm that the mains pressure is within normal bounds and that the gas supply shut-off valve is unblocked. In the event that injector adjustments are required, calling a master is preferable.

Error Eeprom. Resetting the boiler and the settings is usually sufficient. The error is less frequently a sign of a malfunctioning electronic control board.
