Model / Performance
  • TOB 18
  • Key Facts
  • Specification
  • Downloads
  • Modulating output from 6.6 to 18.6 kW, always matched to the current heat demand
  • Proven combustion principle with pressure vaporisation
  • Low power consumption on account of technology that does not require oil preheating or oil evaporation
  • Standard seasonal efficiency [to DIN] net cv up to 105 %
  • Optimum accessibility for easy maintenance and inspection
  • Highly efficient, variable speed EC oil pump motor reduces power consumption
  • Can be operated with standard fuel oil, low sulphur fuel oil EL or biofuel oil (B10)
  • High grade oil filter with vacuum gauge as part of the standard delivery
  • ISM7i LAN/WLAN module allows communication via smartphone, laptop or PC
