Uni Condens 8000 F (145 - 640 kW)

The Uni Condens 8000 F boiler type is a high-efficiency stainless steel condensing boiler. It is characterised by its flexibility and compact dimensions.

  • Condensing boiler for commercial applications from 145 to 640 kW, e.g. for hotels, schools, hospitals
  • Can be operated with gas or low-sulphur fuel oil with low emissions
  • Low pollutant emissions and compact external dimensions
  • Simple hydraulic assembly (no minimum flow rate required)
  • Two separate return circuits for high and low temperatures


  • The Uni Condens 8000 F stainless steel condensing boiler is the ideal solution for heating applications between 145 and 640 kW. The boiler can run either on gas or on low-sulphur heating oil. Installation is easy as the boiler is compact, takes up minimum space and weights relatively little.
  • Intelligent water flow using separate return connections provides the ideal conditions for optimum condensation and thus high standard utilisation ratios. When running on oil, the Uni Condens is capable of a standard utilisation ratio of up to 104%. Up to 110% is even possible when running on gas.

The Uni Condens has an effective condensate heat recovery surface with special profiling of the tubes, so that the maximum utilisation of the condensation potential is achieved. The construction with burnout combustion chamber ensures that there is clean combustion and low emissions. The two return flow sockets guarantee optimum separation into high-temperature and low-temperature heating circuits. The substructure of the boiler can be removed for easy transport.

Equipment level

The unit design of the Uni Condens 8000 F is equipped with a modulating gas fan burner or 2-stage oil fan burner, depending on the fuel selected. The boiler is thermally insulated at the factory and delivered in its cladding. The CFB control ensures the convenient control of the boiler.
