The end product building on many years of experience: the COB-2
The new COB-2 is available in four versions with a rated heating output of between 15 and 40 kW and is perfectly suitable for new builds or modernisation projects. The COB-2 is based on Wolf’s decades of experience with oil condensing boiler technology. In addition to maximising efficiency, Wolf decided that the COB-2 should also be simple to maintain while also focusing on reliability and longevity. Long-term tested components such as aluminium/silicon heat exchangers and robust ceramic flues guarantee the highest level of operational safety.
The new COB-2 is efficient in terms of both oil and power consumption. This removes the need for electric oil preheating. The two-level appliance also automatically adapts to demand and manages with a power-saving 3 watts in standby. Wolf has also taken sustainability into account: As an alternative, the COB-2 can also be operated with B10 bio oil without any problems. The new generation of condensing boilers is also extremely quiet (COB-2-15: 53 dB(A)).
Small room - no problem
The new COB-2 condensing boilers come in a compact refrigerator-style format. They take up just 0.34 m² and can be installed in a corner, making them ideal for extremely small rooms. The COB-2’s robust frame and optimised ease of carrying mean that it can be easily integrated in small or cramped rooms. The COB-2 oil condensing boiler is 100% compatible with the previous COB generation.
The COB-2 is a compact unit which makes the best possible use of the space available as it can be connected to optimally coordinated Wolf components. The TS-160 and TR-160 DHW cylinders can be easily installed to increase the condensing effect. It can also be optimally combined with the WOLF CWL-T-300 mechanical ventilation unit for a visually perfect appearance in the most confined spaces. All of this together in an area covering less than 1 m².
Easy maintenance and operation
The boiler is operated using the intuitive Wolf BM-2 control unit. The commissioning assistant identifies Wolf components and guides the user directly and successfully through the configuration. The Wolf Flip&Clean system with an integrated workbench, the central plug and the single-piece mixer head make the COB-2 an extremely maintenance-friendly appliance. With the Wolf Link home internet interface, integrating the appliance into a smart home system is child’s play. This makes it possible to monitor the system and implement optimisations remotely, or connect it up with Amazon’s digital assistant Alexa.
