Overview of benefits

8 good reasons for you and your customers

1

WOLF oil equipment COB 2

Flexibility for modernisation or new buildings

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).

2

WOLF oil equipment CSM

Quick commissioning and uncomplicated maintenance

Well thought out from control to maintenance: The commissioning assistant in the BM-2 programming unit identifies WOLF components and guides the user directly and successfully through the configuration. A central plug and the integrated workbench make the COB-2 an extremely maintenance-friendly appliance.

3

WOLF oil equipment point 3 COB 2

Maximum robustness and longevity

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 flues guarantee operational safety. The pressure atomisation technology ensures high efficiency and is known for its operational safety.

4

WOLF oil equipment CSM

Uncompromising reliability

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 safe combustion assured by a perfectly pre-set degree of recirculation.

5

WOLF oil equipment CSM point 5

Fits into the smallest of basements

The COB-2 B30 only requires about 1/3 sqm of space: Thanks to its compact “fridge-style” format, it fits perfectly into any installation location, and its excellent 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.

6

WOLF oil equipment point 1 COB 2

Saves not only oil, but electricity too

Thanks to innovative technology, all WOLF oil condensing boilers dispense with the electrical oil pre-heating process. The two-level boiler also automatically adapts to demand and only consumes a mere three watts in standby mode! Sustainability has also been taken into account: As an alternative, the COB-2 B30 can also be operated with B10 bio oil without any problems.

7

WOLF oil equipment point 7 COB 2

Directly online

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. 

8

WOLF Oelgeraete point 8 COB 2

Ideal complete solution, also available with a cylinder and ventilation

Put together your own individual building services centre: The COB-2 can be extended for even greater efficiency. Add a perfectly coordinated hot water stratification cylinder to create the COB-2-TS 160 system or a cylinder with an internal indirect coil to create a COB-2-TR 160 system. 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.
