Vitobloc 200

The Vitobloc 200 Type EM‑100/173 is a medium‑output combined heat and power (CHP) unit designed for commercial buildings, industrial facilities, residential complexes, and local energy centres with a continuous heat demand. It enables the simultaneous generation of electricity and heat, significantly improving fuel utilisation and reducing overall energy costs.
With plug‑and‑play delivery, proven engine technology, CHPQA certification, and advanced remote monitoring, the EM‑100/173 is a reliable and economically attractive solution for decentralised energy generation.

Vitobloc 200

Electrical Output – 99.0 kW

The unit generates 99.0 kW of electrical power, making it ideal for on‑site self‑consumption and reducing dependence on grid electricity.

Thermal Output – 173.0 kW

The recovered heat can be used for space heating, domestic hot water, or process heat, ensuring high overall system efficiency.

Smooth‑Running Engine with Three‑Way Catalytic Converter

The gas engine is optimised for low vibration and smooth operation, while the three‑way catalytic converter reduces exhaust emissions and supports regulatory compliance.

Economical Generation of Heat and Power

By producing electricity and heat at the same time, the system achieves much higher fuel efficiency than separate heat and power generation.

Integrated CHP Control System

Central control manages:

Electricity generation
Heat recovery
Load‑dependent operation
Safety and fault monitoring

Energy Management Integration

Designed for integration into:

Building energy management systems (BEMS)
Industrial automation platforms
Decentralised and district energy systems

Remote Monitoring & Diagnostics

Enables real‑time system monitoring, early fault detection, and faster service response.

Automated Base‑Load Operation

Ideal for facilities with steady heat demand, allowing long operating hours and high efficiency.

How does CHP improve overall fuel efficiency?

CHP uses heat that would otherwise be wasted during electricity generation, resulting in significantly higher total energy utilisation.

Is the Vitobloc 200 EM‑100/173 suitable for 24/7 operation?

Yes. The robust engine design and integrated control system support continuous, base‑load operation.

How does remote monitoring improve operational reliability?

It enables early fault detection and proactive maintenance, reducing unplanned downtime.

Can the system be installed quickly?

Yes. Thanks to plug‑and‑play delivery and factory testing, installation and commissioning are fast and reliable.
