Lyra 19

Boiler range dedicated to the technical room


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:

  • electronic modulation

  • self-cleaning brazier in cast iron 

  • very large ash tray

  • advanced electronics

  • 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)

  • electronic circulator

  • 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.
