Description
The Narvi Stone Cage Flue Cover is a stackable stone cage that fits around the flue of a wood-burning sauna heater, putting heat that would otherwise escape up the chimney to work. The extra stone mass means water cascades more slowly between the stones, so the steam lasts longer and feels softer, and using the cage also reduces the protective distances required from flammable material. Sections can be stacked to use the heat of the entire flue, with a refined appearance that particularly suits large stone capacity heaters such as the Narvi Stony, Inari and Narvi Velvet. Each cage measures 40 cm high by 25 cm in diameter and is available in stainless steel or matte black.
