AHS – the alternative
solution
Siemens and the environment
The customized products and systems
made by Siemens help reach compliance
with the Kyoto protocol. Our declared
objective: Increased usage of environ-
ment-friendly and inexhaustible energy
in place of fossil fuels. This is made possi-
ble by optimized products and efficient
solutions in connection with renewable
forms of energy. Siemens markets a con-
sistent range of products and systems for
use with heat pumps, micro combined
heat and power, solar plants, and much
more.
Solutions for heat pumps
Heat pumps excel in high efficiency and
thus in environment-compatible use of
resources. To ensure efficient heat pump
control, Siemens markets a comprehen-
sive range of innovative products.
Electronic controllers and valves, match-
ing sensors, and a wide choice of operat-
ing and display units can be easily com-
bined to create basic systems, be it for
single-family houses or larger, more com-
plex buildings – with no extra effort for
engineering.
Solutions for micro combined heat
and power
Micro combined heat and power (mCHP)
embodies the next generation of heating
systems. Today, our heat is produced by
conventional heat sources, such as boil-
ers and heat pumps, and electric power
comes from the outlet in the wall. In
Europe, electric power is produced pri-
marily by thermal power stations. For
every kWh delivered, 1.3 kWh are lost
due to waste heat and transportation
losses. It makes sense if, at the same
time, the heat source also generates elec-
tric power – in the house, for the house.
For the consumer, this means: Own
mCHP station in the house, which sup-
plies not only heat but also two thirds of
the electric power required by an average
household with 4 persons.
Solutions for solar
Heat production based on solar energy has
proven its worth for decades. It is techni-
cally mature, environment-friendly, and
protects our climate. Solar energy is capa-
ble of covering 60 to 90 percent of the
annual energy required for DHW heating
and 25 to 50 percent for space heating.
