HOW IT WORKS

The thermal cooker is endowed with a boil-
er to exploit the heat produced by the de-
vice through a system with carrier fluid for
heating and instant production of sanitary
hot water. During the working of the ther-
mal cooker, the water inside the internal
tank of the cooker is heated. Through two
dedicated serpentines, the heat transfers to
the heating system or the circuit for the pro-
duction of sanitary water. It is important to
note that the fluid in the tank of the ther-
mal cooker is not directly in contact with the
water of the thermosanitary system. They
3.2 REMOVING THE BOILER SIDE
To make the installation easier, in STP ther-
mal cookers the boiler side can be removed
also after the placement of the device.
The internal wall of the thermal cooker has
an hole that allows to access the vain under
the boiler tank and so makes the connection

are two separate circuits. For the circuit of
the heating system there is also a pump for
the circulation, ruled by a programmable
electronic control unit. The circuit of the
sanitary water, instead, works thanks to the
pressure of the incoming cold water. The
boiler of the thermal cooker is predisposed
with a tank which makes a good thermal
flywheel and it also makes an open expan-
sion tank, assuring the safe working of the
device.
of the pipes easier.
To remove the side, unscrew the 4 screws on the
front of the thermal cooker and unhook the
side from behind, as indicated in the picture.
To fix the side, it is necessary to invert the
process.
