Description of the appliance
The ATAG Premier E-SHR boiler is a room sealed,
condensing and modulating central heating boiler, with or
without an integrated hot water facility.
The built-in fan sucks the combustion air from outside and
provides full premixing of the gas and air. The gas mixture
is guided through the ceramic burner which is fitted above
the heat exchanger. As a result of the small flame height
a compact construction is possible. The combustion
gasses are exhausted after passing through the stainless
steel heat exchanger. The formed condensate water is
discharged through the waste trap.
The boiler has been tested according to valid CE* standards
and has a CE* certificate and SEDBUK A-rating.
The operating efficiency of the boiler is higher than 98% (on
upper value Hs). As a result of its compact construction the
radiation, convection and stand by losses are very low. The
emission of damaging substances is far below the standard
set for equipment with the gas quality-control label for clean
combustion.
The boiler is provided with an automatic venting program.
In case of a recently topped up or filled up installation this
program takes care of the removal of any present air in the
boiler. In this case the control will check the water pressure
and if it is too low, will report this on the display.
The boiler anticipates the heat requirement of the central
heating installation or the hot water supply. As a result the
boiler will adjust its capacity to the installation and will
switch on less often, which means that the boiler will
operate longer and at a low level. It is possible that the
boiler will only have to switch on once an hour. In this case
the aim is to obtain maximum comfort and efficiency.
In order to be able to anticipate installation heat
emissions the boiler has been fitted with a proportional
gradient control system. After the boiler goes into
operation this control provides a uniform increase of
power, instead of immediately burning at full power. When
the installation does require full power the control will
adjust as required. By this means a uniform increase of
the water temperature is effected.
If an outside sensor is connected, the control will operate
weather-dependent. This means that the control
measures the outside temperature and the flow water
temperature. On the basis of this data the control
calculates the optimal flow water temperature in the
installation.
The E-SHR-T combination boiler provides a hot water
supply by means of a plate heat exchanger fitted in the
boiler and provides a constant hot water temperature of
60°C (factory setting). A heat retention device ensures a
minimum temperature of 30°C of the plate heat exchanger,
which benefits comfort.
