Product Portfolio
  • BLUE STREAM - the idea for more efficiency

  • You will quickly be won over by the inner values of the new CGB-2 series of condensing boilers from Wolf. The efficiency concept has moved on from the previous series, and now offers four notable benefits:

    1. The self-calibrating combustion controller that adapts to the prevailing gas quality means that the gas:air mixture needs never to be adjusted again. This also applies to changing gas qualities (e.g. if biogas is mixed in). Furthermore, the system can modulate down to a minimum output of 1.8 kW. This translates into fewer burner starts, extremely clean combustion and the highest level of efficiency.

    2. The low standby losses, for which Wolf appliances have a high reputation and receive praise in many consumer tests, have been improved yet further. It is not only fossil fuels that are becoming ever more expensive – the price of electricity keeps going up, too.

    3. The intelligent pump control unit addresses this issue by further reducing the overall auxiliary power demand. No overflow value and no return temperature raising function are required – for the highest utilisation of the condensing effect.

    4. The intelligent control technology, which can be adjusted and optimised by smartphone or PC, lets consumers regulate the system precisely in accordance with their heat demand.

      • Wolf Heating technology - economical and efficient.
          • Oil heating technology

          • Oil heating technology - classic and future-proof with condensing boilers.
              • Oil condensing boiler TOB

              • State of the art oil condensing technology

                The TOB is based on the same general principle as the COB – the German consumer association "Stiftung Warentest" test winner. However, Wolf development engineers have now been able to improve the burner unit even further. The most pertinent new development concerns the use of the modulating combustion principle that employs pressure vaporisation and the patented mixing swirl nozzle. Oil preheating and oil evaporation are not required, which saves on auxiliary power consumption.

                During combustion, the pump rate is continuously matched to the prevailing demand with the highly efficient and variable speed EC oil pump motor. This ensures the highest efficiency with very clean combustion, whilst the already low auxiliary power consumption is reduced even further. The TOB, just like its gas equivalent, the CGB‑2, modulates its output according to the actual demand. It is also available as the TOB-TS with an adjacent stratification cylinder.
              • Oil condensing boiler COB

              • Economical and efficient - COB oil condensing boiler

                      Solar heating in combination with a Wolf boiler usually leads to an energy efficiency class A+ (package label) for the complete heating system.

                    • CRK-12 tube collector

                    • The tube collector operates with a heat exchanger in the vacuum tube system. This achieves high absorber temperatures, and enormous efficiencies, even at low levels of solar radiation.

                      In the spring and autumn in particular this allows enough solar energy to be collected that, in addition to hot water generation, central heating can also be supported.
                      In addition to the aesthetic design, the tube collector offers the particular advantage of easy installation and servicing. It is supplied fully preassembled. It is also worth mentioning the fitting position, and the zero-maintenance, extremely durable vacuum seal provided by the cladding and absorber tubes. The absorber and reflector surfaces are therefore optimally protected from ageing and dirt in the vacuum, and therefore have extremely long lives.

                        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.

                          • Control module BM

                          • 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:

                            • easy operation
                            • problem-free commissioning and servicing
                          • Control module BM-2

                          • "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).

                          • BUS INTERFACE ISM8 KNX NETWORK

                          • 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).

                          • Smartset-Operating-App/Contractor level

                          • 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.

                          • Interface module ISM7I/ISM7E

                          • 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.

                          • Interface module ISM9

                          • 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:

                            • A central unit is used to connect all Smart Home peripherals
                            • For the radiator actuator with integral room temperature sensor, a default temperature can be see directly on the drive
                            • The controller module for individual room temperature control continuously compares the actual temperature with the set temperature and regulates the flow rates of the heating/cooling water via the thermal actuators of the distribution system
                            • The solution for underfloor heating: The actual room temperature and the set room temperature are transmitted by the programming unit or the room sensor
                            • The room sensor also captures the relative humidity (optional)
                        • Industry, trade, municipalites - Heating technology

                                                • Wolf Power Systems - In-house electricity and heat generation

                                                • A combined heat and power unit essentially consists of a combustion engine and a generator combined with heat exchangers.

                                                  Natural gas, sludge gas and biogas are likely sources of primary energy. The combustion engine, a gas-burning four stroke engine, drives a generator. The generator converts part of the energy used into electrical power. The electricity is used in the consumer network or is given directly to the power supply company.

                                                  Wolf BHKW units have the same essential structure over the full range of powers: a frame constructed of steel sections forms the heat exchanging unit with the connections for the heating supply and return lines, exhaust and fuel.
                                                  The unit comprises a plate heat exchanger that takes heat from the engine's cooling water, a shell and tube heat exchanger that exchanges heat with the exhaust, and a flue gas cleaning unit.

                                                  A combined heat and power unit can achieve an efficiency of about 90%, meaning that 90% of the primary energy is converted into electricity and heat. If the radiated heat can be included, the efficiency can even reach about 95%. The efficiency of a conventional power station is between 30 and 40%. The advantages are clear.
