eltherm Water Comfort System
– simply energy-saving
In modern society the supply of pure potable and non po-
table water, both hot and cold, is an important contribution
to comfort and well-being which should be readily available.
We assume that the water supply is clean and sterile, but
unfortunately this is not always true. An invisible threat to
health is legionella bacteria. These bacteria cause two kinds
of clinical problems, which behave differently in the course
of disease. One known as Legionnaires Disease normally
causes symptoms similar to pneumonia and can result in
death. The second one so called Pontiac Fever has symp-
toms like influenza but with quite rapid healing.
Legionella, especially in heated water between 30° and
45°C, can cause a threat to health, if small drops of water,
e.g. when taking a shower, are inhaled. Legionella formation
can be prevented by merely changing the water tempera-
ture. Cold water under 20°C and warm water over 55°C
constitute poor growth conditions for legionella bacteria,
therefore the water should be heated up to 60°C once a
day to purge the system. This procedure is called thermal
disinfection.
If the disinfection measures are incorporated in the planning
phase of a water line system, remarkable cost savings can
be achieved. However, retrofitting of a thermal disinfection
system is normally possible without any problems. It is
especially important to install the system in buildings which
present high risk of infection to the occupants, such as hos-
pitals, nursing homes and schools, but it also makes sense
to install the system in private housing.
The eltherm Water Comfort System provides the energy-
saving solution to keep warm water steadily available and to
fight legionella bacteria effectively.
Advantages of the eltherm Water Comfort System for you:
-
High user friendliness by intuitive adjustment
-
Simplified entry. A lot of details are already
preset for choice
-
Logical and clear composed menu
– no
confusing icons
-
Complicated calculations to adjust the system
are not necessary
-
An automatic operating mode ensures
legionella bacteria prevention even if the
system is not adjusted individually already.
-
No overheating of the system because of
heating and heat maintenance with self-
regulating heating tapes.
-
The moisture proof heating tape ensures
longer durability.
-
The heating tape is available in three nominal
outputs.
-
The length of the heating tape can be varied
freely as you can cut it to length from roll.
-
An additional heating circuit for frost protection
in combination with a self-regulating
heating tape prevents freezing of an
additional cold water pipe.
-
Cost saving up to 65%, because a circulation
system and a circulation pump is no longer needed.
-
Considerable energy saving because of optimized
temperature gradation and abolition of the
circulation pump.
-
An additional temperature sensor on the boiler
enables in ideal temperature maintenance balanced
between boiler and water pipes
-
Ideally matching accessories enable an
individual design according to your require-
ments => a plug-and-play version is possible
if wished
-
The system fulfills accepted international
standards for legionella avoidance (e.g.
Arbeitsblatt W 551 of DVGW in Germany)
-
The system is approved by VDE and fulfills
the EN 61000-3-3/11.* That means, because of
the soft start function there is no flickering light
when energizing the heating tape.
The considerable simplification of installation makes the
eltherm Water Comfort Systems to the optimal solution for
drinking water heating and drinking water conduit facilities.
* "Flicker" Standard. Please contact us for details.
