Charnwood External Air Supply Kit

Charnwood External Air Supply Kits are designed to enhance stove performance by supplying combustion air directly from outside, rather than drawing it from within the room. This ensures a cleaner burn, improved efficiency, and consistent performance -especially in well-insulated or airtight homes.

By maintaining a constant source of fresh air, these kits help your Charnwood stove achieve maximum heat output, reduced emissions, and improved overall comfort.
