High-performance energy bundle for residential buildings

Fuel cells powered by natural gas or biogas are the energy supply of the future for both single- and multi-family houses. They ensure the reliable supply of environmentally friendly energy throughout the year – but you’ll barely hear them doing it.

When integrated into a heating appliance, Sunfire’s Solid Oxide Fuel Cells (SOFC) can be used to replace dated heating systems or supplement existing heating appliances. They can also be used in combination with renewable energy technologies. Users benefit from outstanding efficiency and reliability coupled with low running and maintenance costs.

The high-performance energy bundle supplies buildings with cosy heat whenever it is required. What is more, environmentally friendly electricity produced according to the principle of cogeneration ensures both protection from rising electricity prices and the satisfying feeling of making a positive contribution to the process of energy transition.
