Galileo 1000 N

Galileo 1000 N: The name comes from Galileo Galilei. The Italian natural scientist born in 1564 was far

ahead of his time and made groundbreaking discoveries in his field. The “1000 N” in the name of the fuel

cell heater refers to the electrical output of approximately 1000 Watts achieved using natural gas.

Heat and power from fuel cells: Compelling advantages

Forward-looking and environmentally-friendly efficiencyFuel cell technology is one of the most ecological ways to generate energy from natural gas or biomethan. Compared to supplying heat purely using a gas condens-ing boiler and electricity from the grid, up to 50% of carbon dioxide emissions can be prevented when heat and electricity is supplied by “Galileo 1000 N”. With “Galileo 1000 N”, HEXIS has developed a fuel cell system that eliminates the need for gas condensing boilers in houses and small apartment buildings.

“Galileo 1000 N” directly converts natural gas efficiently, environmentally-friendly and practically silently into electricity and heat, meeting a large part of an average household‘s electricity requirements.

The user-friendly system design ensures easy maintenance and intuitive operability. This makes “Galileo 1000 N” ideal for users who place high demands on functionality, sustainability and appearance.

Fuel cell heater “Galileo 1000 N”

• replaces conventional boilers and also generates electricity to meet demands

• is ideally suited for restorations and renovations thanks to the straightforward installation and without the need for major structural changes

• operates with extremely low emission levels: very quietly and with the least amount of pollutant emissions for active climate protection

• extremely compact design for space-saving installation• uses the employed fuel with maximum efficiency• ensures the supply of space heating and hot water,

even in case of power outages• combines state-of-the-art technology with user-friendliness• thanks to the integrated network interface,

the device settings can be accessed easily and across the system

Independent, ecological and intelligent

Using a decentralised energy supply

through a combined heat and

power system (CHP) is characterised

by the simultaneous generation

of mechanical and thermal energy.

Here, the mechanical energy is

converted into electrical power, while

thermal energy, consisting of

waste heat, is used entirely to generate

space heating and hot water.

“Galileo 1000 N”, how ever, does not

produce mecha ni cal energy.

Instead, it produces electricity directly

using an electrochemical process.

The idea behind GalileoThe idea behind developing “Galileo 1000 N” was to largely cover the typical energy requirements in a house or small apartment building using a fuel cell heater. It was designed to generate heat as well as electricity tailored to meet on-demand requirements. The goal is to achieve optimum overall efficiency. To do this, only a minimum quantity of inexpensive natural gas need be supplied to the heater, since it is used with the greatest possible efficiency. The power produced here helps considerably reduce the electricity purchased from the grid.

“Galileo 1000 N” enables private households to produce decentralised energy and represents a pioneering technology for using the limited amount of fossil fuels available. After all, decentralised energy generation reduces transmission losses and significantly improves the CO2 balance.

The model with a bright future: Decentralised energy generation

Active climate protection

Compared with gas condensing boilers

and obtaining electricity from the

public grid, fuel cell heaters reduce

CO2 emissions up to 50%. Fuel cell

heaters are the only combined heat and

power technology that can also be

used intelligently in buildings with low

heat requirements.

When generating electricity and heat separately, the overall efficiency is currently only approximately

60%, since around 40% is lost as waste heat. By contrast, with the decentralised combined heat and power

generation system using HEXIS fuel cells, efficiency is increased to over 90%.

How Galileo worksThe fuel cell provides an electrical output of 1 kilowatt and a thermal output of approximately 2 kilowatts. If the building heat requirements exceed this value, an integrated gas burner can supply up to an additional 20 kilowatts of thermal heat. In terms of heat production, the HEXIS system is comparable to a modern gas condensing boiler. Its ability to also produce power is what sets it apart from conventional heaters.

Heat and electricity from natural gasThe HEXIS fuel cell system converts natural gas into a synthetic gas consisting of hydrogen, carbon monoxide and residual methane. The high temperature fuel cell converts this synthetic gas into electricity and the resulting heat produced is used to meet space heating and hot water requirements.

Efficiency and sustainability thanks to fuel cells

Small cell with a major impact

The HEXIS fuel cell system converts

hydrogen from natural gas based

on oxide ceramic fuel cells (SOFC:

Solid Oxide Fuel Cell). The fuel

cell ultimately converts hydrogenated

gas with superior efficiency into

electricity and heat by means of an

electrochemical process.

Fuel flows over the anode and air flows over the cathode. The resulting oxygen concentration

gradient between the electrodes drives the oxygen ions through the electrolyte and thus generates an

electrical current.

A personal power station that you can rely on

Galileo design and componentsGalileo is a compact heater and essentially consists of two parts. The top part houses the fuel cell module, where the fuel cell stack and fuel preparation unit are inte-grated. The bottom part houses the components for energy conversion, for supplying heat from cogeneration and for the provision of additional heat. A dual-chamber heat exchanger serves as a central, structural component. Among other things, it contains the auxiliary burner along with the ventilator and heating circuit pump.

A hot water circuit and a conventional hot water cylinder can use the waste heat from the fuel cell and the auxiliary burner for space heating and hot water. An inverter converts the direct current into 230 V AC. The flow of exhaust gases is combined in a condensate collection container. The fuel cell fan integrated in the container draws the process gases through the fuel cell module and provides the air for the electrochemical reaction in the fuel cell. Galileo operates in a partial vacuum, thus preventing fuel from escaping into the environment.

User-friendly cutting edge technology

The straightforward and fast

installation of Galileo requires hardly

any structural adjustments to

the building, making it particularly

well-suited for restorations and

renovations. The system is operated

using cutting-edge technology:

Galileo control unit‘s touch sensor

allows the configuration of all

system settings and provides access

to all operating data. At the same

time, the system can also be easily

operated on a PC, thanks to the net-

work interface integrated in the heater.
