Economical production of heat and electricity

A gas-fired cogeneration plant (CHP) simultaneously generates heat and electricity. 

With its performance, it is designed for a range of applications including residential and commercial businesses. On the heating side, the CHP unit operates in parallel to a boiler. Both heat sources are connected to the heating system for the production of heat and hot water.

Benefit from decentralised power generation

When power is generated in power stations (centralised power supply), heat is created that is often lost to the environment without being used. The utilisation of this heat, e.g. for heating buildings, reduces heat losses and lowers emissions that are damaging to the environment. 

Combined heat and power generation enables up to 36% of primary energy to be saved and is therefore one of the most efficient energy-saving methods available today.

High efficiency with condensing heat exchanger

Every CHP module with an electrical output of up to 20 kWel is equipped at the factory with a condensing heat exchanger. The larger units can be supplemented with a condensing heat exchanger. This raises the overall efficiency to up to 95 percent, which minimises fuel usage.

Factory assured output

Prior to despatch, each individual CHP unit is subjected to extensive tests on the in-housetest bed. As part of these tests, specified output values for the unit are documented, keeping the effort when commissioning the system at the customer's premises to a minimum. Viessmann hands over these units fully tested and ready for use.

World-class customer service

From initial consultation at the plannning stage through to expert after sales support, you can be sure that Viessman's world-class customer service is always available.
