FREEHEAT is a novel wind tower technology that provides passive building ventilation and heating cost effectively and with minimum energy demand.

Professionally tested and verified at BRE Groups’ building science centre, FREEHEAT is a multi-directional wind tower that optimises heat pipes achieving a heat recovery of 3.4°C leading to a 20% cut in energy usage.

  • Reduces the need for air conditioning, lowering costs and carbon emissions
  • Improves building energy ratings and targets
  • Improves indoor air quality minimising the transmission of airborne infections and preventing the sick building syndrome (SBS)
  • Produces no background noise
  • Works alongside other heating and cooling systems to ensure sufficient ventilation for all seasons and conditions
  • Has no moving parts, resulting in minimal maintenance requirements
  • Is easy to install

Whether you are new to passive ventilation or looking to upgrade your existing system, Free Running Buildings is here to help.
