Woodfire Passiv Boiler Stove

The Passiv is a unique wood boiler stove designed to be suited to newer homes as well as old. The fire gets hot in the insulated firebox which means that the wood burns more completely. Heat is then extracted above the fire using heat exchange tubes. This results in a high efficiency and low emissions. 


  • Over 85% efficient. 
  • Low heat to the room.
  • Ecodesign compliant.
  • Suitable for pressurised systems.
  • Can take all of its air via an external duct.
  • Easy to use controls

We would often partner the Passiv with one of our Airsmart controllers - which adds in automatic control of the stove and will also open an air vent to the room when the door is opened - meaning that it is unlikely that you would need to install a permanently open air vent to your well-sealed home. 

The Passiv won the award for Build-It's Stove of the Year 2021.
