Boiler range dedicated to the technical room
CERTIFIED ACCORDING TO EUROPEAN STANDARD EN 303-5 / 2012
The boilers Lyra have a wide exchange surface and thus ensure heating of large areas and excellent water yields.
The advantages make them extremely comfortable and suitable to provide healthy heat using environmentally sustainable fuels:
self-cleaning brazier in cast iron
very large ash tray
possibility of switching summer / winter
daily / weekly programming
compact and elegant design
remote control with backlit graphic display
These machines, in addition to being equipped with all electronic, mechanical and hydraulic safety devices required by the regulations in force, are equipped with:
thermostatic mixing valve (anti-condensation)
8 liters expansion vase
3-way diverter valve with priority to DHW system
manometer to read system pressure
It is recommended to install a hydraulic separator and/or a puffer on the system to optimize operation. The buffer capacity will vary depending on the water content of the system.
On the return circuit, a chemical-physical water treatment system must be installed, for instance a magnetic dislimer.
