 Up
To 30% Lower Gas
Bill
Corolla combi boilers can
recover a major part of the lost heat by condensing the
flue gas. The
flue gases which are cooled until the
are below the condensation point (54 °C)
are condensed and they leave their heat to
the combi boiler, which provides up to 109.2% efficiency. The
consumers can feel it directly with up to
30% lower gas bill compared to conventional combi
boilers.

Real High Efficiency
Many people fall into the
mistake of thinking that the efficiency of a combi
boiler are always equal to what is written in
the technical data sheet; however, theese values are valid
only for a short period of the
year when the combi boiler runs in
full capacity. Actually, a combi boiler is almost
always used with a low or medium adjustment value
and in that case, it can be
seen that the efficiencyof conventional combi boilers are 20
to 35% lower than that of condensing combi
boilers. |

Corolla Condensing Combi Boiler's Principle Of
Working
The combustion circuit is made of
tinplate and it is seperated from the environment. The
air and gas mixture is pushed to the burner by a strong
fan; A short flame created by the combustion section
immediately communicates with the exchanger and always
guarantees an efficiency higher then 98%.
The high heat transfer surface area enables an
intense heat exchange between the gases that occur due
to the combustion in the exchanger and the water
circulation in the central heating circuit. The
temperature of the flue gas decreases down to the
condensing temperature and the flue gas, which is almost
cooled down at that point (only 3°C higher than the
circulation water temperature of the device) is
discharged by a 50 mm diameterpolypropylene pipe, while
the condensing water is collected in a container with
siphon and then it is discharged.

Exchanger
Basically Consists Of Theese
:
-
Micro-flame burner
-
AISI 316 L steel collecting
group  -
A
pipe made of bimetal : Copper inside (water circuit)
and steel outside (gas circuit)
-
It
is coiled spirally in the group
-
A
cylindrical case which retains the heat in the
combustion chamber and touches it to the pipe that
ensures a perfect thermal cycling of the flue
gas. |

Full
Modulation
These
combi boilers benefit from the principle of discharged
gas condensation, which is an effective
and fundamental physical phenomenon. Thanks to our bimetal
alternative, as well as other mechanisms
that adjust the combustion and provide high temperature
output during going and returningi the following
mechanisms provide gas condensation at any type
of devices (even at conventional ones) :
Modulation
fan; the speed can be adjusted momentarily
for the power requested to be exercised.
Modulation gas valve ; always guarantees the
correct air-gas relation in the combustion chamber.
Modulation pump;
adjusts the cycle of the thermal liquid
circulating in the exchanger according to the
temperature increase between the intake and outlet.
Available at
all models; these devices enable momentary adjustment of
the air, water and hydraulic circulation according
to the selected heat adjustment and ensure
the perfect operation of the combi boiler. |

Control System
Corolla 26-35 models are
available with "soft touch" buttons and digital screen
which enable adjusting the temperature very simply
unlike the outdated push buttons. With this panel, the
benefical parameters for the electronic control system
of the combi boiler are loaded and its fast and
efficient functionning is obtained. |
