HEXIS fuel cell systems combine cutting edge technology
with environmentally-friendly efficiency (A++). 

Combined heat and power (CHP) technology by fuel cells


With “Galileo 1000 N” HEXIS has engineered a fuel cell heating appliance that leapfrogs conventional condensing gas boilers in single-family or small multi-family homes. The “1000 N” refers to its electrical output of 1000 Watts by using natural gas from the public grid.


Galileo 1000 N converts natural gas in a high efficient, environmentally friendly and silent manner into heat and electricity. The system covers the whole heat demand for room-heating and hot-water preparation and also the base load of the annual electricity demand.


Galileo is created for sustainable thinking enthusiasts searching for a masterpiece of engineering. It is characterized by the following features:


  • Uses fuel with a maximum of efficiency. Employing combined heat and power / cogeneration principle via electro-chemical energy conversion

  • Holistic approach by supplying domestic radiators and hot water needs with fuel cells’ excess heat

  • Replaces conventional boilers of single-family or small multi-family homes, but also generates electricity

  • Compact and lightweight, due to an integrated product architecture for a minimum of installation effort

  • Ensures both space heating and hot water supply, also in case of electrical power cuts

  • Maintenance friendly and manufactured in serial production, since standard components of the industry are used

  • Combines state-of-the-art technology with user-friendliness

  • Extremely low emissions: very quiet and lowest pollutant emissions

  • Integrated network interface for external remote access e.g. via PC and smartphone

More Electricity from Fuel Cells

In Winterthur, work has been underway for almos 30 years on the development of fuel cells that convert natural gas into electricity and heat. With a new generation of fuel cells,... Mehr

Galileo 1000 N successfully launched:

All Galileos have found their customers. The successor to the Galileo is currently being developed and will be marketed through the usual Viessmann sales channels. Currently Viessmann already offers a very attractive and reliable fuel cell heating unit. Vitovalor
