2.1 Equipment level of the Ecostream
cast iron boilers Logano GE315,
GE515 and GE615
Fig. 1 Ecostream cast iron boiler Logano GE615 with
Logamatic 4311 control unit
The Ecostream cast iron boilers Logano GE315, GE515
and GE615 are tested to EN 303, type-tested and CE-
designated. Quality assurance measures to
DIN ISO 9001 and EN 29001 contribute to the high
manufacturing quality and functional reliability.
All Ecostream cast iron boilers are made from Buderus
special GL 180 M grey cast iron which is resistant to
corrosion and high temperatures. They are designed for
thermostream technology. This is why they are suitable as
low temperature boilers for modulating operation with no
minimum start temperature.
Ecostream cast iron boilers feature all-round thermal
insulation and painted casing (RAL 5015). The thermal
insulation on the Logano GE315 and GE515 cast iron
boilers is 80 mm thick, and on the Logano GE615 cast
iron boilers is 100 mm thick. The combustion chamber
and the secondary heating surfaces are easily accessible
through large front doors that can be pivoted to the left or
right.
The boilers are supplied either in individual sections
(Æ Fig. 41) or as a pre-assembled boiler block.
