Gas condensing centre

Put your trust in the high tech successor to the WOLF test winner.

The stratification cylinder technology in the CGS-2L brings your house up to date with some of the latest developments in heating technology. This is because the "stratification cylinder principle" has a huge advantage compared to older technologies: it guarantees hot water quickly and simply, even in large quantities. Furthermore, advanced insulation technology prevents inefficient cooling, so you always get a consistent supply of hot water from your tap. And of course, the CGS-2L is extremely quiet in operation. Ideal for your detached or two-family house and your entire family if you need convenient and reliable DHW heating.
