Keeping to the same design as our original E-Tec range, the E-Tec NXS system boiler features a renewed heat exchanger. The coil remains stainless steel while the casing is made of a composite thermoplastic, which not only makes it more durable, it also reduces the lift weight of the boiler.


  • Stainless steel heat exchanger moulded in thermoplastic to make the boiler lighter
  • Grundfos hydroblock assembly with Delta T variable speed operation pump
  • Adjustable heating flow temperature to allow increased efficiency
  • Range output customisable to the system requirements
  • Combined expansion relief with condensate drain
  • Weather compensation compatible with a simple external sensor connection
  • Open Therm and Alpha BUS control compatible
  • Removable push fit flue connection for quick installation of vertical or horizontal flue configurations


The high output ProTec Plus range has been designed with siting flexibility in mind.
