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.

Compelling advantages
Forward-looking and environmentally-friendly efficiency
Fuel 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 condensing 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.
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
“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.

waste heat, is used entirely to generate
space heating and hot water.

Instead, it produces electricity directly
using an electrochemical process.

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

The idea behind Galileo
The 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.
heat requirements.
“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.

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 works
The 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.
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
Heat and electricity from natural gas
The 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.

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.

Galileo design and components
Galileo 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 integrated. 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.
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 network interface integrated in the heater.
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.
