Your optimal solution<br />
Your optimal ECOTHERM steam solution<br />
For steam systems much more components<br />
are required than for hot water<br />
systems. The spectrum ranges<br />
from oil or gas burners over feed<br />
water tanks, water treatment, clean<br />
steam generators, condensate recovery<br />
systems, steam separators up to<br />
the control panel with a touch panel.<br />
There fore ECOTHERM already plans<br />
80 to 90 percent of all details for a system<br />
in the design stage. This ensures<br />
that the suggested time schedule really<br />
works, that the costs for the project<br />
suit the suggested budget and that the<br />
desired performance can be achieved<br />
by the system. ECOTHERM steam<br />
systems are mainly installed in hotels<br />
(e. g. for the laundry), in hospitals<br />
(especially clean steam generators<br />
for e. g. cleaning the surgical instruments)<br />
or in industry.<br />

8 ECOTHERM <strong>Steam</strong> <strong>Solutions</strong>
Products: Economizers<br />
Economizers<br />
Potential of savings for an<br />
economizer for a steam boiler<br />
• Boiler efficiency without<br />
ECO: 88% - 91%<br />
• Boiler efficiency with ECO:<br />
94% - 97%<br />
A boiler economizer is a heat exchanger<br />
device that captures the “lost or waste<br />
heat” from the boiler's hot stack gas<br />
which could not be used inside the boiler<br />
furnace (due to physical reasons;<br />
i. e. boiler water temperature). The economizer<br />
typically transfers this waste<br />
heat to the boiler's feed water or return<br />
water circuit, but it can also be used to<br />
heat up domestic water or other process<br />
fluids. Capturing this normally lost<br />
heat reduces the overall fuel requirements<br />
for the boiler. Less fuel equates<br />
to money saved as well as fewer emissions<br />
- since the boiler now operates<br />
at a higher efficiency. This is possible<br />
because the boiler feed water or return<br />
water is pre-heated by the economizer.<br />
Therefore the boiler's main heating circuit<br />
does not need to provide as much<br />
heat to produce a given output quantity<br />
of steam or hot water. Again fuel savings<br />
are the result. Boiler economizer<br />
improve a boiler's efficiency by extracting<br />
heat from the gases discharged.<br />
<strong>Steam</strong> boilers<br />
For steam boilers, the economizer is<br />
a typically heat exchanger through<br />
which the feed water is pumped. The<br />
flue gases, having passed through the<br />
main boiler area will still be hot.<br />
The energy in these flue gases is<br />
used to improve the thermal efficiency<br />
of the boiler.<br />
Feed water<br />
The feed water thus arrives in the<br />
boiler at a higher temperature, than<br />
it would be the case if no economizer<br />
was fitted. Less energy is then<br />
required to raise the steam. Alternatively,<br />
if the same quantity of energy is<br />
supplied, then more steam is raised.<br />
The result is a higher efficiency. In<br />
broad terms a 10°C increase in feed<br />
water temperature will give an efficiency<br />
improvement of about 2%.<br />
Shell boilers<br />
Optimizing energy consumption<br />
The heat output recovery from smoke<br />
gas is limited. At smoke gases from oil<br />
or gas firing plants there’s a steam content<br />
of 100 to 120 g/kg; the condensing<br />
point of this water content is situated at<br />
57°C. For heating up the feed water by<br />
an economizer it’s only possible to use<br />
the sensible heat (dry heat) because<br />
the feed water has to have a minimum<br />
temperature of 90°C - so it’s not possible<br />
to condense the smoke gases and<br />
to use the condensing energy too.<br />
FEED WATER TANK<br />
CHIMNEY<br />
ECONOMIZER<br />
BY-PASS<br />
STEAM BOILER<br />
On shell boilers the economizer is<br />
either installed directly at the boiler<br />
or - also possible - installed as a separate<br />
unit. The smoke gas coming<br />
from the last boiler smoke gas pass<br />
is guided into the economizer.<br />
Note: The smoke gas temperature<br />
leaving a normal boiler is about<br />
50°C to 80°C higher (full load<br />
and clean heating surfaces) then<br />
the saturated steam temperature.<br />
The minimum allowed smoke gas<br />
temperature (behind economizer)<br />
depends - mainly - to chimney design.<br />
For steam boilers operated at 10<br />
bar(g) the temperature levels which<br />
could be used at the economizer<br />
are about 250°C down to 140°C<br />
(smoke gas out from boiler compared<br />
to smoke gas out from eco)<br />
- which results in a fuel saving of<br />
about 5% comparing to boilers without<br />
economizer. The feed water<br />
temperature will rise from 105°C to<br />
round 135°C in that case.<br />

Products: Chimneys<br />
Chimneys<br />
CE-certified, double-wall, grimecombustion-resistant<br />
insulated<br />
chimney - respectively exhaust gas<br />
system - made of stainless steel by<br />
Jeremias, Germany.<br />
The chimney respectively exhaust gas<br />
plant is made of industrial, double-wall<br />
stainless steel system elements. It is<br />
used as an outer wall chimney as a<br />
standard but it is also suitable for assembling<br />
in buildings, as long as the<br />
system is floor-overlapping. But in this<br />
case the system has to be covered by<br />
a cored hole (which has to fulfill the<br />
fire protection requirements). This<br />
chimney can also be used for roof heating<br />
and for all connection piping.<br />
The exhaust gas plant is made of<br />
high-alloyed, austenitic stainless steel<br />
(AISI 316Ti). Its longitudinal seams<br />
are gas-shielded, arc welded and passivated<br />
via WIG.<br />
The production is externally controlled<br />
by an independent testing institute.<br />
The compliance of constant goods is<br />
checked by an internal control.<br />
The inner shell is made of 0.6-1.0 mm<br />
thick stainless steel (AISI 316Ti). The<br />
outer shell has got the same thickness<br />
at the stainless steel material number<br />
AISI 304. This material thickness offers<br />
perfect safeness against buckling<br />
and folding. The single elements are<br />
connected by plug-in sockets with<br />
overlying clamp fittings against scrolling<br />
and slipping.<br />
The inner shell of the system is able<br />
to extend freely as because of the<br />
construction of the single elements<br />
the inner shell cannot slip and consequently<br />
it remains centered without<br />
fixing on the outer shell.<br />
Thermal bridges between inner and<br />
outer shell are avoided because of<br />
this construction. The special mineral<br />
insulation (thickness 32mm) between<br />
inner and outer shell is high-temperature<br />
resistant and incombustible (material<br />
class A1 according to DIN 4102).<br />
Specifications<br />
• Thermal resistance class<br />
of the system: at reference<br />
temperature = 0.501 m²/K/W<br />
• Visible surface high-glossed<br />
(standard).<br />
• Possible designer surface:<br />
beamless, painted or grinded,<br />
as well as in copper<br />
• Inner diameter area of<br />

Feed Water Tanks & Deaerators<br />
Description<br />
The feedwater deaerating plant, consisting of the feedwater<br />
tank and the deaerator, removes dissolved gases such as<br />
oxygen, carbon dioxide and other non-condensable gases<br />
from boiler feedwater and makeup water.<br />
For the operation of steam boilers with high thermal load<br />
on the heating surfaces boiler feedwater must be treated<br />
and conditioned.<br />
The boiler feedwater must be free of hardening constituents<br />
in order to prevent the formation of scale on the boiler heating<br />
surfaces. The presence of dissolved oxygen and carbon<br />
dioxide causes severe corrosion of metal boiler parts. The<br />
feedwater deaerating plant is custom designed for each<br />
application and meets essential thermo dynamic requirements<br />
to achieve optimal performance.<br />

The make-up water and return condensate enters the<br />
deaerator that is fitted with a series of tray compartments<br />
to provide maximum spilling. Heating steam is fed into the<br />
deaerator from below. The make-up water and return condensate<br />
are deaerated and flow directly into the feedwater<br />
tank, which is flanged to the deaerator. The feedwater tank,<br />
which is heated by means of a steam injector, heats up the<br />
feedwater to 105°C.<br />
The solubility of gases in water can be described by Henry<br />
Dalton‘s law of absorption which states that gas solubility in<br />
a solution decreases as the gas partial pressure above the<br />
solution decreases. This means that the gas solubility in a<br />
solution decreases as the temperature of the solution rises<br />
and approaches saturation temperature.<br />
The make-up water and return condensate is distributed<br />
over the series of trays and comes in direct contact with<br />
the heating steam. This process reduces the solubility of<br />
oxygen and carbon dioxide and removes these gases from<br />
the feedwater. The released gases work their way to the<br />
top of the vessel where they are vented from the deaerator<br />
via the vent line.<br />
A temperature-controlled heating system for warming up a<br />
cold feedwater tank is provided.<br />
Due to the fact that the feedwater temperature is above<br />
100°C enough net positive suction head (NPSH) is required<br />
to ensure that the weight of the column of water in the line<br />
exerts enough pressure at the feed water pump suction to<br />
prevent the formation of steam bubbles and therefore the<br />
water from cavitating. Therefore a support construction is<br />
required.<br />

Products: Blow Down Coolers<br />
Blow Down Coolers & Flash Vessels<br />
<strong>Steam</strong> boilers must be blown down to remove contaminants,<br />
as a too high level will cause foaming and scaling<br />
of the boiler tubes. A build-up of solids at the bottom of the<br />
boiler could also have serious consequences. Most modern<br />
boilers are fitted with TDS controls to remove dissolved<br />
solids, and a blowdown valve that is opened at regular<br />
intervals to remove precipitated solids.<br />
Because the bottom blowdown valve is opened just a few<br />
seconds per day, it is not economical to recover the heat,<br />
yet water cannot be discharged to drain unless it is cool.<br />
Nowadays, blowdown vessels have replaced blowdown<br />
pits as the recommended way of cooling this water.<br />
Blowdown from TDS controls should ideally be connected<br />
to a heat recovery system inside a flash vessel. Where<br />
this is not practical, TDS blowdown may also be piped to a<br />
blowdown vessel.<br />
User benefits:<br />
• Three inlets as standard with dedicated bottom blowdown<br />
and TDS connection.<br />
• Fully complies with the requirements of the European<br />
Pressure Equipment Directive 97/23/EC.<br />
• Complete systems normally readily available from<br />
stock.<br />
• Quick and easy to install and maintain.<br />
For flash vessels an internal heat<br />
recovery system is provided.<br />

• Boiler pressure<br />
• Number of boilers<br />
• Duration of blow down<br />
• Blown down line size<br />
• Length of blow down line between the boiler and<br />
the blow down vessel<br />
• Blow down regime<br />

Chemical Dosing<br />
Water filter<br />
Hardness Control<br />
The chemical dosing is used to<br />
control the dosage of oxygen<br />
binder, prosphat and sulfite in<br />
the feed water of steam generators.<br />
The system basically consists<br />
of a solenoid diaphragm pump,<br />
mounted on a dosing tank for<br />
storage of the chemical dosage.<br />
The plant is individually designed<br />
according to the defined boiler<br />
parameters and is delivered fully<br />
pre-assembled.<br />
The water filter is used for the<br />
coarse filtration of fresh water<br />
and is mounted prior to entering<br />
the water treatment system.<br />
The size is determined by the<br />
required amount of fresh water,<br />
the characteristics of the fresh<br />
water and the size of the water<br />
softening plant.<br />
For the ease of cleaning an integral<br />
backwashing system of the<br />
filter is used.<br />
For automatic control of the<br />
water hardness for larger systems<br />
often a self-controlled water<br />
hardness monitoring unit is<br />
used.<br />
Thus, the steam system is always<br />
perfectly protected against<br />
too hard water.<br />
Alternatively, manual water test<br />
kits can be used, which require a<br />
continuous measurement of the<br />
water quality by the operator.<br />

Reverse Osmosis is a process that is used to remove a<br />
wide range of salts to provide water of a high purity. Osmosis<br />
is a natural process involving fluid flow across a semipermeable<br />
membrane barrier. It is the process by which<br />
nutrients feed the cells in our bodies and how water gets to<br />
the leaves at the top of trees. Reverse Osmosis systems,<br />
in their basic form, consist of a pressure pump, housing<br />
and the membrane. Water is forced into the housing under<br />
pressure and the pure water (or permeate) is collected and<br />
passed to service.<br />
Reject water (or concentrate) is collected from another outlet<br />
and routed to drain, with a portion of the concentrated<br />
water recycled back to the inlet of the pump. This means<br />
that the portion of water sent to drain is kept to a minimum.<br />
The controller used on the RO system constantly monitors<br />
the quality of the permeate water and is also linked with<br />
safety controls on the system.<br />
RO plants must be supplied with softened, de-chlorinated<br />
or de-chlorinated anti scalent dosed water. A duplex softener<br />
is recommended for continuous operation.<br />
The size of the RO and choice of membrane will be determined<br />
by the permeate quantity required, feed water salinity<br />
and permeate quality expected. Low energy membranes<br />
allow the units to run at pressures around 10 to 13bar, and<br />
as such the pressure booster pumps required to generate<br />
the pure water are smaller, and the power consumption is<br />
reduced significantly.<br />
Additional recommended is also a storage tank which is<br />
used for reception of the pure-water.<br />
The size of this tank / these tanks should be in coordination<br />
with minimum and maximum RO water demand to ensure<br />
constant operation of the RO system.<br />

European Machinery Directive 98/37/EC, European Low<br />
Voltage Directive 72 / 73 / EEC and European Electromagnetic<br />
Compatibility Devices Directive 89/336/ EEC.<br />
This product is not a pressurized vessel and therefore<br />
does not need to comply with the European Pressure<br />
Directive 97/23/EC.<br />
• Receivers are manufactured of mild steel or SS<br />
304/316. All sizes are fitted with adequately sized vent,<br />
overflow, drain and inlet connections flanged to PN16 or<br />
screwed. A water level gauge and control is provided.<br />
• Pumps are designed for operation under conditions of<br />
low NPSH to handle hot condensate with the minimum<br />
of flooded suction. They are directly coupled to motors<br />
having class F insulation (class B temperature rise) and<br />
motor enclosure rating IP54 minimum.<br />
• Control: Receivers are fitted with solid state level<br />

Technical details on page 51.<br />
Pressure Reducing Stations<br />
It is more efficient and economic to<br />
produce steam at high pressures<br />
ready for delivery through the distribution<br />
system. This may mean that the<br />
pressure needs to be reduced prior to<br />
the point of use or for different parts<br />
of the system. A reliable method of<br />
providing pressure reduction is to use<br />
a pilot operated pressure reducing<br />
valve station.<br />
Every pressure reducing station is<br />
custom designed according to<br />
required steam flows and pressures.<br />

Automatic Blow Down Systems<br />
The automatic boiler blow down<br />
system allows the built up of sludge in<br />
the bottom of the boiler to be flushed<br />
regulary by a timer controller which<br />
cyclically opens a pneumatically<br />
actuated blow down valve. Blow down<br />
interval and duration are to be set<br />
by the user according to the water<br />
characteristics. The system avoids<br />
wasted heat and repetition or<br />
omission which occurs with manual<br />
blow down.<br />

The TDS automatic control system<br />
limits the level of dissolved salts and<br />
minerals contained in the boiler water<br />
to the allowed level, which avoids<br />
carry over due to excessively high TDS<br />
levels and minimizing the amount of<br />
blowdown required.<br />
The system continuously measures,<br />
just below the water surface level,<br />
the waters electrical conductivity and<br />
compares with the set point. If the<br />
measurement is higher the TDS valve<br />
is opened until the measured value<br />
drops below the set point.<br />
Blow Down<br />
Control Valve<br />
Level Control for <strong>Steam</strong> Boilers<br />
To control and to keep a constant water<br />
level in a boiler, a level control is<br />
used, which gives a signal to the controler<br />
to switch on/off the feed water<br />
pump.<br />
Essential are also level safety devices<br />
as low and high level cut off systems<br />
and gives alarms.<br />
Low level systems consisting of two<br />
independent level probes connected<br />
to two distinct level relays. They provide<br />
a visual and acoustic alarm in<br />
case the water level falls below a preset<br />
value and permanently stops the<br />
boiler, which only is able to operate<br />
again after a manual reset.<br />
At a high level system there is also<br />
an acoustic and visual alarm in case<br />
the boiler gets over flooded. Then the<br />
boiler feed water pump is stoped until<br />
the water level returns to the normal<br />
condition.<br />

need for your system.<br />
<strong>Steam</strong> Flow Metering<br />
For the universal measurement of the<br />
volume/mass flow of gases, steam<br />
and liquids an individually selected<br />
flow meter can be used.<br />
Maximum fluid temperature ranges<br />
from –200°C up to +400°C, and pressure<br />
ratings up to PN250 are possible.<br />
There is also no maintenance because<br />
no moving parts are required.<br />
Trough the inbuilt flow measurement<br />
computer the software initial settings<br />
save time and costs.<br />
The high resistance to vibrations,<br />
temperature shocks and water hammer<br />
makes the flow meter very robust.<br />
Feed Water Pumps<br />
A feed water pump is considered to<br />
guarantee continuous feed water flow<br />
to the steam boilers.<br />
In case of fault of the feed water<br />
pump, a second reserve pump is<br />
supplied, installed in parallel to the<br />
operating one.<br />
For the protection of the pumps, low<br />
water control in feed water tank and<br />
strainers are installed.<br />
For easy maintenance and servicing<br />
each pump can be removed by<br />
closing the shut off valve before and<br />
after each pump.<br />
To guarantee non cavidation on the<br />
feed water pump impeller, every pump<br />
is individually designed according to<br />
the steam plant specification.<br />

Products: <strong>Steam</strong> Headers, Separators, Sample Coolers<br />
<strong>Steam</strong> Headers<br />
ECOTHERM steam headers are<br />
individually designed according<br />
to the maximum boiler load.<br />
Any pipe connection and steam<br />
distribution can be considered in<br />
design stage. Every steam header is<br />
equiped with one or two relay points<br />
according to the size of the header. All<br />
headers are manufactured according<br />
to European pressure directive (PED).<br />
<strong>Steam</strong> Separators<br />
Sample Coolers<br />
The ECOTHERM steam separator<br />
provides the total<br />
solution for all pipelines carrying<br />
steam, air or gas where water droplets<br />
are in suspension.<br />
The purpose of steam separators is<br />
to collect small droplets of water and<br />
separate them from the steam in the<br />
pipes.<br />
The ECOTHERM baffle type separator<br />
is designed to achieve this separation<br />
by having an internal volume many<br />
times greater than the inlet pipework.<br />
The flow velocity of the steam, air<br />
or gas is significantly reduced as it<br />
enters the body. The relatively heavy<br />
water droplets impact on the internal<br />
baffles and are then directed to the<br />
separator drain connection and removed<br />
from the system using either a<br />
steam trap, or when used on air or gas<br />
distribution system, a liquid drainer.<br />
The ECOTHERM baffle type separator<br />
is a highly efficient product, operating<br />
over a wide velocity range, leading to<br />
improved system performance.<br />
Technical details on page 53.<br />
ECOTHERM sample coolers are used<br />
to take samples of water or steam from<br />
boilers at high temperature and pressure.<br />
The counter-current flow through<br />
the shell and coil condenses the steam<br />
and cools hot fluids efficiently to enable<br />
safe sampling. When hot pressurized<br />
liquids are being cooled the sample<br />
cooler prevents “flashing-off” which<br />
can be dangerous and will result in an<br />
inaccurate sample. By utilising corrosion<br />
resistant materials for the cooler,<br />
contamination is minimized, and<br />
service life maximized.<br />
Clear results<br />
The boiler and feed water has to be<br />
analyzed daily. The sample cooler<br />
helps to cool the hot boiler and feed<br />
water down to a safe temperature.<br />
Only cooled samples will give clear<br />
results.<br />
Description<br />
The hot water from boiler and feed<br />
water tank is conducted through a<br />
stainless steel cooling serpent. This<br />
serpent is girdled with cold water in a<br />
small stainless steel vessel.<br />

Description:<br />
The clean steam is generated by plant steam or by electrical<br />
energy. The clean steam generator is loaded with softened<br />
and heated water (without lime, PH-neutral conductivity,<br />
0–30 μS). This water will become clean steam. The level<br />
control guarantees an optimized level of water and causes<br />
an alarm if the water level falls below the alarm switch.<br />
The pressure of the clean steam is controlled according to<br />
the requirement by regulation valve.<br />
A conductivity measuring unit regulates the level of minerals<br />
in the water to protect the vessel.<br />
To avoid any dirt inside the clean steam generator and to<br />
guarantee a high quality of water and a long life of the vessel<br />
is installed a blow down valve which is controlled automatically.<br />
The blow down cooler cools the hot water of the blow down<br />
to 40°C to drain the water and to avoid burnings.<br />
The clean steam generators can be manufactured completely<br />
pre-piped and wired, mounted on a stainless steel<br />
support frame.<br />

Vapour Heat Exchangers<br />
The ECOTHERM vapour heat exchanger is used for:<br />
• Pre-heating of boiler feed water<br />
• Condensate relief<br />
• Degasification of fresh softened water and condensate<br />
• Flash steam heat recovery<br />
For this process, thermal degasification, steam is used which deaerates the<br />
gases (N 2<br />
, O 2<br />
, CO 2<br />
) out of building. Hence there is energy lost on deaerator.<br />
This “lost energy” can be used for pre-heating of cold softened water or domestic<br />
cold water.<br />

Advantages<br />
Efficiency<br />
One of ECOTHERM's key values is<br />
“sustainability”. This especially drives<br />
the company to produce plants which<br />
consume as less energy as possible at<br />
reaching the desired output in means<br />
of hot water or steam. Therefore<br />
ECOTHERM has installed its own<br />
innovation management system at the<br />
headquarters in Austria.<br />
This standardarized process ensures<br />
to permanently improve existing products<br />
and components and create new<br />
products to open new possibilities to<br />
further improve the efficiency of the<br />
ECOTHERM systems.<br />
The results are innovative and technologically<br />
leading products as e. g.<br />
the ECOTHERM shell & tube heat<br />
exchanger with the patented free<br />
floating turbulator rods. With this heat<br />
Design<br />
exchanger, hot water system needs<br />
minimal floor space since hot water can<br />
be produced just on demand.<br />
Another example of ECOTHERM's innovative<br />
and efficient products are the<br />
ECOTHERM high capacity clean steam<br />
generators. Using a heat recovery unit,<br />
primary energy is saved. Moreover the<br />
clean steam generators have a compact<br />
design and are skid mounted. This saves<br />
floor space in the plant room and<br />
time for installation on site.<br />
For all individual ECOTHERM turnkey<br />
systems a detailled 3d visualization<br />
is already created in design stage.<br />
Usually 80 to 90 percent of all details<br />
are included in the design. This ensures<br />
that the final system meets the<br />
project's budget, is manufactured and<br />
delivered in time and that the desired<br />
performance of the system can be<br />
reached for sure.<br />
Moreover the CAD data from the design<br />
are the basis for the start of the<br />
operations scheduling. Due to the saved<br />
parameters e. g. also the bill of<br />
lading is created.<br />
Finally the service man uses the 3d<br />
visualization at the touch screen of<br />
the control panel in order to monitor<br />
and modify the most important process<br />
parameters.<br />
Optimal overview on the touch screen<br />
of the control panel for monitoring<br />
and controlling the system due to the<br />
3d visualization.<br />
30 ECOTHERM <strong>Steam</strong> <strong>Solutions</strong>
Advantages<br />
Individuality<br />
According to the project specifications,<br />
the ECOTHERM engineerings<br />
choose the suitable products for your<br />
individual steam solution. All components<br />
are perfectly coordinated with<br />
each other. This ensures the maximum<br />
efficiency of the system and therefore<br />
the maximum return on investment<br />
of your money.<br />
Premium Quality<br />
On the one hand ECOTHERM as a<br />
company and its products are certified<br />
and approved according to the highest<br />
European standards. But “premium<br />
quality” at ECOTHERM means much<br />
more. It is the philosophy to supply the<br />
best possible system to the customer.<br />
If we are not satisfied with a solution,<br />
we develop our own standard as e.<br />
g. the ECOTHERM touch panel for<br />
the control of the system or the ECO-<br />
THERM insulation solution, which is<br />
outstanding due to its patented components.<br />
These are just two examples<br />
where we set new<br />
standards for the<br />
market concerning<br />
quality. This philosophy<br />
is one of the<br />
main reasons why<br />
ECOTHERM is the<br />
market leader for<br />
individual turnkey<br />
solar, hot water and<br />
steam systems in<br />
the Middle East.<br />
Maximum Savings<br />
ECOTHERM systems consist mainly of<br />
high capacity components. These products<br />
achieve maximum performance<br />
with minimal space requirements. Taking<br />
into consideration that one can utilize<br />
this space for another purpose, this<br />
fact saves a lot of money.<br />
The ECOTHERM microprozessor<br />
control panel optimizes the overall<br />
performance of the system. Due to<br />
the high capacity shell & tube heat<br />
exchangers with the patented free<br />
floating turbulator rods, the burners<br />
are only started at continuous hot<br />
water demand. For small demands,<br />
the hot water in the storage tank is<br />
used. On the other hand only a very<br />
small capacity of the storage tank<br />
is heated up to 60°C. Therefore the<br />
number of burner starts per day is<br />
significantly reduced compared to<br />
conventional systems.<br />
If possible, the experienced ECO-<br />
THERM engineers further equip the<br />
system with an economizer, water<br />
treatment components and a heat<br />
recovery unit in order to further save<br />
primary energy.<br />
