The CGS-2L with stratification cylinder
The CGS-2L gas condensing centre is the larger version of the CGB-2 wall mounted gas condensing boiler. Similar benefits are on offer. As was the case with the previous model, the CGS-2L comprises a wall mounted gas condensing boiler with stainless steel DHW heat exchanger and a stratification cylinder. All these parts are assembled into a practical and compact module, which can be split into units of 35 kg and 49 kg.
The CGS-2R - cylinder with internal indirect coil
The Wolf CGS-2R gas condensing centre is ideal for use in regions with high water hardness. Also compact in size, the CGS-2R is not equipped with a stratification cylinder, but with a cylinder with internal indirect coil designed specifically for this purpose. Short heat-up times are assured thanks to the robust internal indirect coil's generously sized heat exchanger surface area. Highly efficient thermal insulation minimises cylinder cool-down losses.
Incredibly quietly, the Wolf gas condensing centre provides cosy warmth and the central DHW supply in detached houses and two-family homes.
The open combustion boiler ComfortLine CGU-2K series draws the combustion air from the room in which it stands.
Now Wolf has been designed the series new.
The boiler ComfortLine CGU-2K now has an advanced equipment and a high efficiency [HE] pump. This means that the devices comply with the new Ecodesign Directive (ErP). And the required minimum standards of energy consumption have been met.
The newly developed HydroTec system allows the hot water generation to start quickly and easily - optionally using fresh water with stainless steel plate heat exchanger for combi devices or, if demand is high, using a hot water tank from the comprehensive Wolf range.
3-way valves and safety valves are fitted to all devices at the factory, saving additional installation work.
Older devices of usual makes can be replaced quickly and economically using the hydraulic and exhaust side system accessories. Accurately fitting accessory sets for fast assembly are also available for initial installations.
The Wolf FGB
The FGB-series comes in two capacities (28 and 35 kW) and is available in a heating and a combi version. The FGB offers everything an advanced wall mounted condensing boiler needs, operating with natural gas and with LPG. Made in Germany.
A stylish casing and the compact dimension offer many mounting possibilities. The internal components are chosen from very robust and durable materials such as copper pipes, cast-aluminum heat exchanger, a glass fiber reinforced polyamide hydraulic block and a stainless steel DHW heat exchanger in the combi boilers. The straightforward design of the monobloc heat exchanger has large and simple water channels. The High-efficiency pump and fan together with the high thermal conductivity of the heat exchanger lets the FGB easily comply to class A of the ErP directive. Additional components like safety valve, condensate trap, expansion vessel, air vent and a flue gas non-return valve (for multiple-floor systems) are already integrated. Installation and maintenance can be done very quickly by a single person due to the fixing and connection design.
TopSon F3-1 is the high-performance flat plate collector from Wolf, manufactured from environmentally-friendly, single-variety materials that can be separated and recycled in the future without difficulty.
The high quality and engineering enable a product guarantee for five years, and provide an expected service life of 20 years. Its newly developed, deep-drawn aluminium collector basin, which is sealed all the way round, contributes to this high durability.
The difficult mitred corners found on frame constructions, which can be the cause of leaks and have to be sealed with silicone, are simply not present. In addition, a special punching process of the robust aluminium basin provides particularly high resistance to distortion.
Solar heating in combination with a Wolf boiler usually leads to an energy efficiency class A+ (package label) for the complete heating system.
Decentralized mechanical air handling unit with heat recovery
The CWL-D-70 is the ideal appliance for retrofitting existing buildings. It combines efficiency and convenience in the smallest of spaces. This is due to its removable plastic cross- and countercurrent plate heat exchanger, which guarantees at least 80 % heat recovery, as well as its particularly low energy consumption thanks to the use of high grade DC fans. It is because of these fans that you hear so little from the new CWL-D-70 – it is the quietest appliance on the market.
The electric preheater coil (275 W), which is integrated into the appliance and features automatic frost protection control and a standard bypass, takes care of supply air preheating in winter as well as the minimum supply air temperature. A category G4 pre-filter continuously provides clean and pollen-free fresh air. The filter service notification is automatically displayed on the appliance.
The white internal panel features a particularly aesthetic design and can even be coated. The external wall hood is available in white (RAL 9010) or stainless steel. The CWL-D-70 is supplied fully wired. It is especially easy to install, thanks in no small part to the wall sleeve included in the delivery.
Building Services Centre - Comfort domestic ventilation CWL-T-300 Excellent
A team only excels when its individual talents complement each other. Accordingly, the new CWL-T-300 Excellent ventilation unit teams up well with a Wolf heat generator.
Together, the ventilation unit and the heat generator form both a visual and a technical entity. With an optional hydraulic reheater coil, the supply air can be heated as required with a maximum heating output of 3000 W. The required heating output is produced and made available by the adjacent Wolf heat generator, e.g. BWL-1S split air source heat pump, CGS-2 gas condensing centre or TOB oil condensing boiler. It therefore supports the conventional heating system in providing comfortable indoor conditions. The mechanical ventilation system can be installed right beside the respective heat generator due to its new "tower" design.
Otherwise, the CWL-T- 300 Excellent offers the impressive benefits of other units in this series: light and compact design, a removable plastic cross countercurrent heat exchanger with up to 95 % heat recovery.
Energy saving, constant flow EC fans and low current draw of only 36 W also ensure low power consumption. A bypass for night ventilation in summer and a 1000 W electrical preheater coil are included as standard. Equally typical for Wolf: Fully wired unit for quick and easy installation and commissioning. It can be positioned against a wall to save space and serviced quickly and easily from the front.
This building services centre can be controlled easily and conveniently with the BM-2 programming unit, your key to the "smart home" – networked, intelligent and mobile
control for the entire heating and ventilation system.
The advantages of the Wolf BSP stratification cylinder at a glance:
As end units become more complex and more technically subtle, the controller also faces more difficult challenges.
Optimum regulation of temperature zones in a house throughout the year is only one of the challenges solved by the Wolf WRS control system. It is true strength lies in the coordination and control of complete heating systems.
The WRS optimizes and synchronizes even the extended modes of operation with components such as integrated solar technology or air-conditioning equipment.
Yet in spite of these stiff technical challenges, Wolf remains true to its basic principle:
"Smart Home" is the keyword for intelligent, networked building management. The new BM-2 programming module is the key to effective control over heating, solar thermal and ventilation systems.
This convenient device can be used in all appliances belonging to Wolf's new range of condensing boilers, as well as in split air sources heat pumps. The BM-2 programming unit can also be used as an external remote control, fitted in a wall mounting base. For example, the CWL Excellent range of mechanical ventilation systems also interacts seamlessly with this unit because all installed HRS components are automatically recognized and preconfigured via eBUS. In addition, control via smartphone is possible (requires the ISM7i/ISM7e interface module).
Integration into complete building systems
Intelligent building systems are now used to reduce running costs and to make usage more flexible and safe. The KNX bus technology brings significant benefits, including sophisticated control options, the interaction of sensors and consumption devices, as well as the acquisition of consumption data (smart metering).
The Wolf KNX interface kit makes it possible to integrate Wolf system components into the KNX building automation system. In this way, all gas and oil condensing boilers with BlueStream® (CGB-2, CGS-2, CGW-2, CSZ-2, MGK-2, TOB), plus the BWL-1S split air source heat pump, can be integrated. It is also possible to integrate additional components such as the MM mixer module, the KM cascade module, the SM1/SM2 solar collectors, and the mechanical air handling unit from the CWL Excellent series.
If a CWL Excellent is used in standalone mode (without heating equipment), the corresponding external KNX interface set is available in the shape of the ISM8e.
In conjunction with the BM-2 programming unit, data points can be read and written via the KNX network. Actual values and statuses from the respective control units are collected in the ISM8 interface module and made available via the KNX/IP module. Other appliances in the KNX system can read and write these network variables.
The ISM8 can also be used without the BAOS module as an ebus/Ethernet interface (ISM8i – ebus/Ethernet interface set).
Perfect control via smartphone and PC
The user level: Wolf Smartset smartphone app or Wolf portal
In conjunction with the ISM7i or ISM7e interface module and the Wolf portal, the Smartset smartphone app allows users to operate their heating systems conveniently from a smartphone, no matter where they are. An internet connection will only be made if permitted by the user.
The contractor level: Wolf portal
Full access to the selected heating system is possible at the contractor level of the Wolf portal. The system components are graphically illustrated by various schemes, and the associated operation conditions are also shown. Adjustments can be made and parameters called up and modified. In addition, the integral datalogger can record values and conditions, which can also be shown in graphic form. Furthermore, active fault messages and a fault history are displayed.
The service tool: Wolf Smartset PC app
The Smartset application for Windows PCs allows a system to be configured and diagnosed on site, for example during a service call. The connection between PC and ISM7i or ISM7e interface module is established directly with a network cable. The design and functional scope of the Smartset PC app corresponds to that of the Wolf portal including contractor level.
The new LAN/WLAN interface module ISM7i/ISM7e
Your link to the future
Now heating starts to become interesting, because the ISM7i (for installation) and ISM7e (extern solotion for retrofitting) interface module allows the heating system to be integrated into a LAN or WLAN network. For secure communication via the internet, the interface module is simply linked to the existing broadband router which then makes the connection to the secure Wolf portal server.
Remote control via the internet uses either a smartphone via “Smartset”-App or PC, both of which access the convenient browser-based user interface of the Wolf portal.
An internet connection is not required if access to the heating system is to be limited to the local home network.
The Wolf communication system gives contractors access to the Wolf heating system via the internet. Fault messages are automatically sent by email to the system operator and the contractor.
The new interface module is the key
Many customers want to control their heating – not only the overall heating system, but also individual rooms. This is why Wolf has developed the new integration-ready ISM9 interface module. This module features WLAN capability and can easily be integrated into a Smart Home network. For this purpose, Wolf has established arrangements with Smart Home suppliers. Wolf cooperates with wibutler to provide reliable solutions for the individual control of radiators and underfloor heating. The components for individual room temperature control are only available from heating contractors/wholesalers, not from Wolf directly. Additional Smart Home products for lighting, safety, shading, garden, measurement of energy demand, etc., are available from the respective system suppliers. The individual room temperature control is commissioned by trained heating contractors associated with the Smart Home suppliers.
Smart Home components:
The heating solution for larger buildingsWolf also recommends the new MGK‑2 medium-sized gas condensing boiler with 17 to 100 % output modulation at a rated output level of 390-630 kW, or up to 2.5 MW in a cascade. It is available in four sizes. Thanks to its quiet operation and compact dimensions, it is especially suitable for effective modernization or refurbishment of existing buildings.
The new MGK-2 requires no minimum amount of circulating water or return temperature raising facility, making it particularly economical. Furthermore, users will be delighted with the easy operation of the BM-2 programming module, with its built-in colour TFT display and its many new auxiliary functions.

Advantages of the product:
Comfort thermal wheel heat exchanger ventilation unit CRL
For indoor and for outdoor installation
Compact units with heat recovery are designed for controlled ventilation in modern properties. The regulations for energy saving and air hygiene in buildings have led to an increase in the technical and hygienic requirements of ventilation systems. CRL units with heat recovery provide rooms with filtered outdoor air, the volume of which can be adjusted to ensure sufficient supply. At the same time, a corresponding volume of used room air containing CO2 is removed and exhausted. This results in other pollutants such as odours, fine dust, moisture etc. being removed effectively as well.
Whether in the smaller version, the Wolf LH-EC 25 with a flow rate of 2400 m³/h, or in the most powerful version, the LH-EC 100 with a flow rate of 9400 m³/h, all Wolf air heaters feature well-engineered, sophisticated technology and are easy to install and maintain.
