Narvi Stone Cage Flue Cover

Product Description

The Stone Cage Flue Cover increases the efficiency of the stove by better utilising the heat from the flue. The quickest way to an excellent löyly is to have a large stone capacity. The steam last longer and is softer on account of the water taking longer to cascade between the stones of the sauna heater. Using the Stone Cage Flue Cover also reduces the protective distances required from flammable material. The Stone Cage Flue Cover can be stacked to utilise the heat of the entire flue and produces a refined, stylish aesthetic. The stone cage is available in Black or Stainless Steel.

The Stone Cage makes a stylish addition to any wood burning sauna heater but particularly the large stone cage heaters such as the Narvi Stony, Inari and Narvi Velvet.
