Wall mounted gas condensing boiler
CGU-2K

The CGU-2K is the conventional heating solution when replacing an older appliance, and meets ErP requirements.

In September 2015, the EU passed the Ecodesign Directive and decided to move away from conventional heating technology. As a result, only high grade, energy efficient condensing appliances may now be installed in new buildings. As was the case with light bulbs, conventional gas boilers with low temperature technology will be gradually withdrawn from circulation.

So what should you do if you want to replace a conventional boiler in an apartment or apartment block? For such situations, WOLF offers the CGU-2K conventional wall mounted combi boiler, a low temperature appliance. It meets the ErP requirements and is an effective alternative if structural conditions make modernisation too expensive or problematic.
