• Wall-mounted boiler with forced draft C17 MT SPV 31 MEF
  • High, constant efficiency
  • Low power consumption
  • “Optimus” system which allows an annual saving up to 5%, by means of a severe burning control, comparing with the traditional boilers
  • boiler easy to be mounted due to the small boiler sizes electronic ignition and modulation of the flame
  • plate main heat exchanger and secondary heat exchanger
  • continuous modulating gas valve
  • flowmeter for detecting the DHW discharge
  • NTC temperature sensors with ultra-rapid response on the heating and DHW circuits
  • 3-way gas valve
  • control board with LCD display providing a graphical evaluated interface and switch keys
  • different operating modes for the user and the installer
  • the possibility of connecting a chronothermostat or an external temperature probe
  • discharge valve of the boiler
  • “Comfort” function allowing the user not combine the hot water with the cold water anymore necessary for shower but open only the DHW tap

Safety systems:

  • safety relief valve protects the boiler against high pressures which exceed 3 bar
  • water pressure sensor in the central heating equipment
  • air pressure switch providing the discharge of products of combustion in safety conditions
  • safety thermostat for the heat exchanger at overheating
  • electronic board which provides reaching the wanted temperature and guarantees the boiler safety running
  • extreme self-checking system
  • anti-frost system
  • anti-chalkstone deposits system
  • every 24 acting pump anti-blocking system
