auroFLOW Solar Thermal Drainback System

  • Mircogeneration Certification Scheme (MCS) accredited
  • Total system available under one article number
  • Suited for commercial properties


The Vaillant auroFLOW plus drainback system is the result of intensive research and developement and is designed to offer maximum efficiency, high performance and total reliability.

The system combines all of the advantages of the very latest Vaillant solar technologies in an easy-to-specify and install kit, under a single article number.

The flexibility of auroFLOW plus means that it can be connected into a conventional heating or a Vaillant heat pump system, such as ground source or air source, to provide hot water if an when required. The system is also easily upscaled to suit larger commercial builfing applications.

Features & Benefits:

  • Suited to commercial applications such as offices, schools, restaurants and hotels.
  • The Vaillant auroFLOW plus drainback system works 'on deamand' and does not go into stagnation.
  • Simply switching the system off means that there will be no solar fluid in the collector, preventing the need for draining the system down until the building becomes reoccupied.
  • By preventing stagnation, solar drainback systems also maximise the solar gain.
  • Mircogeneration Certification Scheme (MCS) accredited
  • The auroFLOW drainback system comes an an easy-to-specify and install kit under a single article number.
  • The auroFLOW plus can be easily connected into a conventional heating or Vaillant heat pump system.
