3 Description of the boiler
The Rinnai E50C boiler is a room sealed, condensing and modulating central heating
boiler, with an integrated DHW fascility.
The boiler is provided with a compact stainless steel heat exchanger with smooth
tubes. This design is a well engineered principle using durable materials.
The boiler burns gas for supplying heat. The heat is transferred in the heat exchanger
to the water in the central heating system. By cooling down the exhaust gases
condensate is formed. This results in high effi ciency. The condensate, which has
no effect on the heat exchanger and the function of the boiler, is drained through a
condensate collector trap.
The boiler is provided with an intelligent control system (CMS Control Management
System). The boiler anticipates the heat demand of the central heating system or the
domestic hot water facility system.
When an outdoor sensor is connected to the boiler it will operate weather dependantly
using outdoor reset. This means that the boiler control measures the outside
temperature and supply temperature. With this data the boiler calculates the optimal
supply temperature for the installation.

Different boilertypes:
Room sealed boiler
The boiler retreives its
combustion air from outside
then discharges the fl ue
gasses to the outside.
Condensing
Retrieves heat as much as
possible from the fl ue gasses.
Water condensates on the
heat exchanger.
Modulating
Stepless higher or lower
burning according to the heat
demand.
