CALOMA

CALOMA is a combi condensing boiler full premix for efficient gas saving.
The boiler is equipped with condensing module featuring a stainless steel coil and is designed to meet the new European Directives on the use of energy. The boiler is certified class 6, the highest ecological classification in
Europe, thanks to its low emissions of nitrogen oxides (NOx).
Its compact size makes it easy to position and adapt with flexibility to new installations or replacement
of existing units at home, or outdoors in partially protected areas.
The controls are simple, with LCD display, auto recognition of errors, and integrated chronothermostat
programming and climatic control.
The boiler has standard anti-freeze protection, external temperature sensor, voltage protection of the PCB and gas pressure regulator included in the gas valve.

Main characteristics

  • Available in three versions 24, 28 and 32 kW

Advantages

  • High stability of sanitary hot water temperature thanks to flame adjust according to water debit
  • Integradet gas pressure regulator (can function on pressure between 2 ÷ 60 mbar)
  • Automatic restart: repeated restarte precedures in case of lack of gas or draught
  • Three ingition sequences: reduces chance of fault errors
  • Two individual systems for protection against limestone
  • Integrated sanitary hot water debit limiter
  • Pump anti-block system
  • Automatic error recognition
