Combined heat and power (CHP) plant
Vitobloc series Viessmann Werke GmbH & Co. KG

A gas driven combined heat and power unit (CHP) generates heat and power simultaneously. They are sized to suit residential units and commercial operations. On the heating side, the CHP unit operates in parallel to a boiler. For generating heating water and DHW heating, both heat sources are connected to the heating system.

The compact appliances from ESS, member of the Viessmann Group since 2008, are focused on decentralised CHP units with a bias towards heating. Comparatively small units generate electric power for consumption on site. The heat that is generated by this process is used simultaneously, almost without losses, for heating. Any power not required is fed into the public grid and reimbursed accordingly by the power supply utility.
