Since its founding more than 136 years ago the Vaillant Group has been one of the market leaders and technological pace-setters of the heating, ventilation and air-conditioning industry. In line with its corporate vision, Vaillant offers its customers around the world simple, eco-friendly and energy-saving solutions for heating, cooling and hot water. Technologies based on renewable energies, such as solar thermal and photovoltaic installations, heat pumps and wood pellet boilers are thereby becoming increasingly important. There is also a growing demand for environment-friendly hybrid systems that intelligently combine various components with each other, such as solar collectors, hot water storage cylinders and controls. The product portfolio also encompasses highly-efficient combined heat and power appliances based on gas engines for the use in single- or multi-family homes. These microCHP systems represent today’s most efficient gas technology.

What we do

The Vaillant Group counts among the pioneers in developing fuel cell heating appliances, the future of innovative combined heat and power. For more than 10 years, Vaillant Group has successfully conducted development work in this field. In 1998 already, Vaillant Group commenced the R&D activities. In 1998 already, Vaillant commenced the activities in this field and has successfully conducted development work for more than 10 years now. At present a Solid Oxide Fuel Cell (SOFC) microCHP system designed for private homes is tested within a German field trial.

Our role in the ene.field project

Vaillant’s role in the project will be a supplier of FCHA’S and will be responsible for service and maintenance efforts during the operation of the systems. Currently Vaillant extends its demonstration activities with the microCHP fuel cell appliance. Based on the plain and robust SOFC system design 2.0 kW of heat and 1.0 kW of electricity can be produced at the same time. In the ene.field project about 130 of these systems will be deployed within the next years, mainly in 2014. Projects with utilities, municipalities and even end-users are possible in ene.field. All activities will be supported by solid experience of our service organization within several EU member states.
