Narvi Stony Wood Burning Sauna Heater

The beautiful Narvi Stony wood burning sauna heater has been awarded the prestigious Finnish Key-Flag symbol. Coupled with its elegant design and superior material quality, these heaters are in a class of their own. The Narvi Stony is the perfect choice for a customer that enjoys a löyly that is reminiscent of a traditional Finnish smoke sauna or stone heater. The quality of steam is distinguishable from other heaters because of its large quantity of stones, ideal for those who enjoy a prolonged sauna experience.

The refined design of the Stony is further accentuated by its choice of elegant stainless steel or stylish painted black casing. The Stony comes with twin layered adjustable base for ease of installation and reduces heat transfer to the floor of the room. The Narvi Stony is also available as a tunnel model which can be fuelled from outside the sauna.

• The glazed fire box hatch is an excellent choice for ensuring an even flame distribution within the heater whilst also creating a pleasant, cosy atmosphere. The wooden handles and cast iron latch twin perfectly, both comfort and durability, and are vital for ensuring personal safety and pleasantly cool handling during use.
• Narvi heaters are market leaders in emissions and health & safety standards. A point of paramount importance when it comes to the ideal relaxation experience.
• As with all Narvi heaters, 10mm thick steel is used for the firebox, extending time between servicing, a choice that that is borne out of their 'quality-first' ethos. This choice to use thicker, better quality steel than their competitors is one of Narvi's key distinguishing features.

Please note that a suitable flue kit and sauna stones are to be purchased separately. You can browse our sauna flue kits and chimney parts here.
