Detailed Information

The high output ProTec Plus range has been designed with siting flexibility in mind. All the boilers are compatible with our open or concentric push-fit flue systems. They are factory-fitted with a ‘B23’ type flue configuration, which can be changed to ‘C’ type by fitting the concentric flue adaptor.

Specifically designed for larger output requirements, these fan-assisted condensing system boilers provide heating only for sealed central heating systems, or open systems, if required.


  • 3 year guarantee
  • Stainless steel heat exchanger
  • 2m flying mains lead
  • Suitable for single unit or cascade installations
  • Open or concentric push-fit flue systems
  • Built-in plume management
  • Easy access for servicing

While these boilers are supplied with type ‘B23’ flue configuration (open chamber and forced draught), in order to allow flexible siting, the configuration can be changed to type ‘C’ (room sealed) with the use of a special flue adaptor kit.

The boilers can be supplied for use with Natural or Propane Gas (LPG) and are capable of being installed as a single unit or in simple modular formations for even bigger outputs.
