CHP units

Environmentally responsible operation with high levels of efficiency

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

Viessmann compact appliances are designed as 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. 

The overall efficiency of CHP units can reach up to 96 %. The Vitobloc 200 module EM-20/39 achieves thermal efficiency of over 62 % and electrical efficiency of over 32 %.
