At the ISH MHG Heiztechnik is presenting a world
first in the form of its patented high-output
exhaust gas heat-exchanger made from glass tubes.
The new high-tech product is intended for use
exclusively with the EcoStar 500 oil condensing
unit (15 to 27 kW) and will be available from May
2007.

The
innovative
glass
tube
heat-exchanger
represents another new breakthrough for MHG’s
development engineers. For the first time in the
history of heating technology a heat-exchanger has
been made from a total of 32 high pressure
resistant
glass
tubes
enclosed
in
an
acid
resistant special plastic. “For years corrosion
has been a hot topic of discussion within the
sector
in
connection
with
oil
condensing
technology particularly because the technology is
relatively new and only limited operational
experience is available. Now once and for all the
issue is completely ‘done and dusted’ both for
ourselves and for our customers. This progressive
step forward has been achieved through the use of
glass and special plastic. The latter already has
been used in exhaust gas systems where it has an
excellent track record and even permanently
withstands a concentration of acid from the
condensate”, explains Markus Niedermayer, MHG’s
managing partner. “When the innovative glass tube
heat-exchanger is combined with the EcoStar 500
oil condensing unit MHG customers have a product
with a high sales potential incorporating a
feature that really sets it apart”, continues
Niedermayer. What is more, maximum operational
reliability and a long service life are truly
heavyweight arguments in front of customers.
The new glass tube heat-exchanger offers a number
of additional benefits. The patented high-tech
product is manufactured in accordance with the
‘Deutsches Inlandsgebot’ (made in Germany seal of
quality) and in addition to optimum energy
efficiency it is also exceptionally eco-friendly.
The use of glass tubes eliminates metal leaching
and the environmental pollution with heavy metals
this would entail. Minimum construction height is
another benefit along with minimum hydraulic

resistance. As a result, the new system is ideally
suited for installations with several heating
circuits or under-floor heating.
State of the art oil condensing technology: the
EcoStar 500 oil condensing unit
The new glass tube heat exchanger provides a new
premium component upgrade to the EcoStar oil
condensing unit that was launched two years ago.
As hitherto, another core component of the unit is
MHG’s trusted Raketenbrenner®. This tried and
tested dynamic component has now been built into
more
than
1 million appliances and ensures perfect, sootfree
combustion.
The
result
is
a
standard
efficiency of up to 104 percent.
For the remaining components MHG also consistently
adheres to German-made premium quality. The
particularly
compact
heating
boiler
is
manufactured from special, high-quality cast-iron.
With its innovative comfort controller, the highquality enamel hot water storage tanks and the
wide range of plastic exhaust gas systems the
EcoStar 500 oil condensing unit incorporates other
top-quality
components
that
fit
together
perfectly.
Huge installation and servicing time savings
To facilitate the heating professional’s work MHG
engineers have put great emphasis on ease of
installation and servicing. The EcoStar 500 oil
condensing unit is supplied largely pre-assembled
as a ready to fit appliance, providing huge
installation time savings. For example the castiron heating boiler and the high output glass tube
heat-exchanger come fully assembled with complete
hydraulic interconnection. The pipes are extended
to the outside so that it takes no time at all to
connect them to the system. In addition, the screw
connectors on the boiler are pre-sealed as well as
the pipes. It takes less than a minute to hang and
screw the boiler cladding in place or remove it
for boiler maintenance. What is more, maintenance
work does not necessitate disconnection of the
glass tube heat-exchanger either on the exhaust
gas side or the system side; only 4 screw
connections need to be undone for the inspection
opening to be freely accessible. Deposits on the
surface of the glass are minimal – if they occur

Price stability thanks to new materials
The EcoStar 500 oil condensing unit plus glass
tube heat-exchanger is positioned in the same
price segment as the EcoStar 300 oil condensing
unit plus stainless steel heat-exchanger, which
MHG continues to offer as before. Prices for glass
tubes and special plastic are stable compared to
the frequent fluctuations in the market prices for
stainless steel and this is to the benefit of
MHG’s customers.

Wide range of systems to maximise efficiency
In the area of systems technology professional
heating
installation
companies
now
have
a
sophisticated range of thermal solar systems and
solar or buffer storage tanks at their disposal.
Accordingly, the high energy efficiency of the
EcoStar 500 oil condensing unit can be maximised
by using the sun’s heat energy to generate hot
water and support heating.
Also available in a low temperature version
MHG’s range of premium products is rounded off
with the low temperature version (15 to 27 kW), of
the proven EcoStar 200, which achieves a standard
efficiency of 94.5 percent.
