CTC EcoZenith i555 Pro
1. Design of CTC EcoZenith i555 Pro
This chapter illustrates the main components and describes the subsystems
which, in different confi gurations, form part of the main system. For
more information about the EcoZenith confi gurations, refer to the “Pipe
connections” chapter.
1.1 Main components
Control system
The EcoZenith is equipped with
an intelligent control system which
controls and monitors all parts of
the heating circuit. The EcoZenith
ensures that the most economical
way of heating the house and the
hot water is prioritised.
Finned Coil for DHW
The EcoZenith is equipped with a
well dimensioned fi nned copper
coil and does not contain any
heater which can rust. A low
temperature can be maintained
without the risk of legionella
bacteria.
Electric heaters in upper tank
Built-in upper electric heater.
When connected to a heat pump,
the immersion heater acts as
additional heat.
(The top electric heater is an
optional extra)
Lower tank
In the lower tank, DHW is pre-
heated in the coil by the solar- or
heat pump-heated water.
Solar Coil Connections
The well dimensioned, 10 m long,
fi nned coil can be connected
directly to the solar panels.
Electric heater lower
Built-in lower electric heater.
Bivalent shunt valve
The automated mixing valve
ensures that an even heat is
continuously supplied to the
heating circuit. The valve has
double ports and takes the warm
radiator water from the solar and
heat pump heated water in the
lower part of the tank fi rst.
Upper Tank Connections
The upper tank, the additional part,
can be heated by a heat pump and
connected to heat sources such as
electric, gas, oil and pellet boilers.
Heat from a wood boiler is delivered
to this part. Connections are placed
symmetrically on both sides of the
tank.
Insulation
The tank is insulated by 90 mm
thick molded polyurethane foam
for minimum heat loss.
Lower Tank Connections
The heat pump and solar system
are connected to the lower tank.
Water to be heated by wood
boiler is taken from here, and
heat which is to be stored in a
buffer tank is also taken from this
part. Connections are placed
symmetrically on both sides of the
tank.
Insulated tank divider
Between the tank’s upper and
lower tank is an insulated tank
divider. This provides high
temperatures in the upper tank
for good DHW capacity and low
temperatures in the lower tank for
best operating economy.
Heat Distribution Pipes
The heat distribution pipes ensure
that heat from the solar coil is
directed to the upper tank and that,
after DHW is drawn off, cooled
water is directed to the lower part of
the tank to be heated again by solar
energy or heat pump.
Upper tank
In the upper part of the tank, the
warm water in the coil is heated
up to the desired temperature.
Fresh Water Connections
Here you connect the property’s fresh
water connections. The cold water
is fed down to the lower part of the
coiling, where it is preheated.
Top Connection
For connection of expansion
vessel and/or safety valve.
