Product description
Low scaling
On the storage tank side only one deposition of scale is possible.
All the stainless steel heat exchanger pipes in the storage tank
water largely remain without fixed coverings. This means that no
scale can build up which would continuously reduce the effi-
ciency of heat transfer in the course of operation.
The thermal and pressure expansion and high flow rates in the
domestic water heat exchanger release any possible scale de-
posits, which are then flushed away.
Solar utilisation
The hot water storage tank of ROTEX GCU compact can also be
used by solar energy. Depending on the available heat from the
sun, the entire hot water storage tank can be heated up. The
stored heat is used for hot water generation and also for heating
support on types GCU compact 5xx. The ISM ("Intelligent
Storage Manager") controls the integrated 3-way valves in such
a way that the solar heat yield is optimally divided up and used
for the hot water generation and heating support. The high total
storage capacity allows for bridging of the periods without any
solar yield.
If a ROTEX pressurised solar system or an external heating
boiler is used as an external heat generator, this means that only
one of the - listed in section 3.1 - GCU compact with BIV config-
uration is permitted as the primary hot water storage unit.
On the models GCU compact BIV, the complete storage tank is
designed as a hot water zone. It is possible to make thermal use
of solar energy for hot water preparation. In connection with a
ROTEX Solaris plant connected in series (preheating stage), the
solar proportion is optimised.
Safety management
The entire safety management of the ROTEX GCU compact is
entrusted to electronic control. This effects a safety switch-off in
the event of water shortage, gas shortage or undefined operating
states. A corresponding fault signal provides an engineer with all
the necessary information for troubleshooting.
Electronic control
An electronic digital controller combined with the "intelligent" au-
tomatic firing unit of the burner controls all heating and hot water
functions automatically for the direct heating circuit and a storage
tank charging circuit.
Optionally, connected mixer modules
RoCon M1
(
15 70 68
)
can be used to connect and regulate one or more mixed circuits.
All settings, displays and functions are made via the integrated
RoCon BF control. The display and operating elements offer con-
venient operating possibilities.
As an option, for increased convenience, a digital room controller
(
RoCon U1
,
15 70 34
) is available as an option. This can be
used as a remote control and a room thermostat.
Using the optional gateway (
RoCon G1
,
15 70 56
), the con-
troller can be connected to the internet. This means that the
ROTEX GCU compact can be controlled remotely via mobile
phone (using an App).
Condensing technology
The calorific value engineering makes optimum use of the energy
contained in the heating gas. The flue gas is cooled down in the
boiler and in the flue system - when operated independently of
ambient air - such that the temperature is below the dew point.
A part of the water vapour generated on combustion of the gas
thus condenses. The condensation heat is fed to the heating,
unlike low temperature boilers, which makes efficiencies of over
100 % possible (in relation to the lower heating value).
