The fuel cell heater «Galileo 1000 N» is developed in order to cover both the entire heat requirements and the basic requirements for electrical power of a single-family home. The fuel cell supplies an electrical power of 1 kW and a thermal capacity of about 2.5 kW. If heat requirements of the building exceed this value, an integrated gas burner can provide a further 20 kW of heating energy. Concerning the heat production the Hexis system is comparable to a modern gas-fired condensing boiler. In condensing operation it can optionally be run in dependence on the indoor air or not. What distinguishes it from conventional heaters is its ability to generate electrical power.

«Galileo 1000 N» basically consists of two parts. In the upper part there is the fuel cell module which is easily accessible in the case of maintenance. In the lower part there are the components for power transformation, the heat transfer and the supply of the additional heat. A double chamber heat exchanger serves as the central supporting component. The additional burner with blower and gas-air ratio control as well as the heating circulation pump are integrated in there. Over a hot water circuit the waste heat of both the fuel cell and the additional burner can be used for the supply of space heat and hot water. The exhaust gas flows are combined in a condensate collecting pan. The induced draft fan of the fuel cell integrated here provides the air for the electrochemical reaction in the fuel cell. The system operates in low air pressure which means that no fuel can escape into the environment. The transformation from direct in alternating current of 230 V is carried out by an inverter.

You can both change all settings of the system and query all operating data via a pressure/rotary switch at the operating unit. In parallel with this the system can also be operated and/or programmed via a serial interface.
