Woodbox Technology: Luxury Is Control

Some fireplaces simply burn. Others know how to manage a fire. Woodbox-style air control and secondary combustion are designed to give more heat, less work and less waste.

Secondary Combustion: Recovering Energy That Escapes Up the Chimney

In secondary combustion, additional air is fed into the upper part of the chamber, re-ignites gases and returns heat to the home — more output from every log.

  • More heat output from every log.
  • Reduced smoke and particles compared with primary combustion alone.
  • Cleaner glass and chimney when the wood is dry and the system is properly adjusted.

Precise Air Control and a Long Burn Time

You can adjust the intensity of combustion — from a lively start-up to quietly maintaining embers for hours, according to the manufacturer’s instructions.

Frequently Asked Questions

What exactly is secondary combustion?

Additional air re-ignites gases in the combustion chamber before they escape up the chimney — more heat from the same amount of wood.

Does a long burn time mean no supervision?

No. It means maintaining embers or steady combustion for hours when properly adjusted — in line with the manufacturer’s and safety instructions.

Why does the technology make the fireplace more expensive?

Because behind it lies air engineering and controls that reduce waste and improve the user experience over the years.
