Description of the boiler
The ATAG Premier is a room sealed condensing and modulating
central heating boiler which is designed with a hot water facility.
A built in ventilating fan sucks in the combustion air from outside and
provides for a complete premixing of gas and air.
The gas mixture is lead through a ceramic burner which is fitted directly
above the heat exchanger.
Due to the small flame height a compact construction is possible. After
the combustion gasses have passed through the stainless heat
exchanger, they are flued to outside.
Any condensation formed is drained away to waste.
The ATAG Premier E-SHR-T is a boiler designed with an integrated
hot water facility and is provided with a plate-heat exchanger which
supplies a constant water temperature of 60°C.
The unit anticipates the heat required by the heating installation and/
or hot water facility.
By doing so as low as possible heat input is given for the required output.
The boiler is provided with an electrical ignition and energy saving
pump start to prevent waste of energy.
As a result unnecessary system noise is prevented.
When the boiler has been out of operation for a long period of time the
circulation pump will periodically start to prevent seize up. If an outside
sensor has been connected to the unit, the circulation pump will start
automatically when there is a chance of frost. This is the first stage of
frost protection to prevent the danger of freezing.
The efficiency of the boiler is very high and the radiation convection
and standby losses very low. The emission of noxious substances is
far below the fixed standards so the boiler meets the requirements of
SEDBUK Class A and carrys the energy saving logo.
