Gas condensing centre

Powerful yet space saving – the compact CGW-2L gas condensing centre with advanced DHW technology

If space is tight, but your family wants a highly convenient DHW supply, then the compact, wall mounted CGW-2L is the right appliance for you. This condensing centre is equipped with advanced DHW technology. The stratification cylinder principle guarantees hot water quickly and without fuss. This means you can enjoy a relaxing soak in the bath or a long shower whenever you like.

Furthermore, advanced thermal insulation prevents inefficient cooling of the appliance. It keeps the heat right inside the cylinder and therefore ensures that energy-intensive reheating costs are reduced.
