The Vitobloc 200 EM‑401/549 is a combined heat and power (CHP) unit designed for on‑site generation of electricity and heat. By producing both forms of energy simultaneously, it achieves overall efficiencies of around 90%, significantly reducing primary energy consumption compared to separate power and heat generation.

This decentralised energy concept results in primary energy savings of over 30%, alongside substantial reductions in emissions—up to 25% less nitrogen oxides and around 60% less CO₂, depending on the fuel comparison. The Vitobloc 200 is engineered to meet strict technical connection conditions (TAB) of network operators and is delivered as a fully assembled, factory‑tested unit for fast installation and reliable output.
