The regular boilers manufactured by Viessman are designed to deliver central heating with the additional use of a hot-water cylinder and cold-water tank for storage.

These boilers are generally suitable for most medium-sized homes that have a higher demand for hot-water. Models include Vitodens 100-W boilers.

System boilers
