COB-2 B30

The WOLF COB-2 B30 generates cosy warmth using a two-stage modulating operating principle. Find out more about this highlight from the WOLF range of oil condensing boilers.

An appliance for any situation

The WOLF COB-2 B30 oil-fired unit covers the entire range of installation scenarios. With its four power levels COB-2 15–40 kW this product family offers an effective heating solution for existing buildings, from single-family homes to multi-unit apartment buildings.

The COB-2-TS 160 variant also includes a stratified hot-water storage tank as part of the heating system. In the COB-2-TR 160, a coil-type storage tank stores the heat until you need it.

The COB-2 B30 operates with a bio-oil blend. This allows you to meet the “bio-step” requirements outlined in the Building Modernization Act (GModG) and ensures you’re well-prepared for the increasing proportion of biofuels.
