Clean and Efficient Burning

Clean-burning fire heats more efficiently and produces fewer particle emissions. Cleaner air, indoors and outdoors.

 

EI kylmää vetoa

No Cold Draft or Smoke

With a closed air circulation system, the fireplace operates independently, separate from the home's ventilation setup.

Easy Start for Your Fire

Even a well-functioning fireplace can be tricky to light, especially for those new to fire handling. Siro Air saves you kindling, time, and nerves.

Siro Air Makeup Air Chimney

 

For a More Efficient Fireplace

Siro Air makeup air chimney is designed to transport fresh, preheated combustion air directly to the fireplace. The outgoing flue gases heat the intake air to nearly 100°C, significantly improving the fireplace's efficiency.

 

Solves Fireplace Combustion Issues

The chimney is well-suited for homes that lack a directed supply of combustion air to the fireplace. Because there is no need for an external flue, the fireplace can be placed anywhere. With Siro Air, you can forget about common issues in modern homes, such as reverse drafts caused by range hoods and central vacuum systems.

 

Ensures Fire Safety

Siro Air features a similar multi-insulation structure to Siro Unique, providing a guarantee of safety. The closed air circulation further enhances fire safety. This results in the market's best thermal insulation and the smallest safety distances.

Conventional Approach

Combustion air is pulled into the fireplace from within the room. The room and fireplace’s heat is directed back into the fireplace and out through the chimney.

Siro Air Makeup Air Chimney

When combustion air is properly directed, the fireplace does not waste previously heated indoor air, and the heat efficiency multiplies.

The fireplace connection creates a closed system. Combustion and the draft in the chimney force air to move downward in the channel against the flow. The air warms up due to the effect of the exiting flue gases, making the fireplace operate more efficiently.
