Oil condensing boiler

The compact, light-weight boiler with a robust frame and optimised carrying comfort can be easily installed in small or confined rooms. The COB-2 B30 is also fully compatible with the connections to the COB (including flue gas connection).

Well thought out from control to maintenance: The commissioning assistant in the BM-2 programming unit identifies WOLF components and supports users throughout the configuration process. A central plug and the integrated workbench make the COB-2 an extremely maintenance-friendly appliance.

The COB-2 B30 is based on decades of experience with oil condensing boiler technology. Long-term tested components such as aluminium/silicon heat exchangers and robust ceramic fluessupport reliable operation. The pressure atomisation technology ensures high efficiency and is known for its operational safety.

We have equipped the COB-2 B30 with extensive safety features: Additional differential pressure cell for monitoring of supply and extract air, ionisation check and supports stable combustion through a factory-configured degree of recirculation.

The COB-2 B30 only requires about 1/3 sqm of space: Thanks to its compact “fridge-style” format, it is suitable for a wide range of installation situations, and its good accessibility means that it can be mounted on walls or even in corners. The WOLF neutralisation box and lifting pump can be installed in the boiler to save space.

Thanks to innovative technology, WOLF oil condensing boilers dispense with the electrical oil pre-heating process. The two-stage boiler automatically adjusts operation according to demand and has a standby power consumption of 3 watts. The appliance is also suitable for operation with approved B30 bio oil.

With the WOLF Link home interface module, which can be integrated into the boiler, and the WOLF Smartset technology, it is now easier for you to connect systems and to monitor your customers’ appliances at all times. You can use these to check the condition of the system, optimise settings or contact WOLF service without needing to visit the site.
