Narvi Steam Master Wood Burning Sauna Heater

Product Description

The Narvi Steam Master wood burning sauna heater is the ideal choice for those who prefer a good sauna heat without drying the sauna air. The enameled steel casing is the perfect fusion of Scandinavian refined style, durability and utility. Not only does the casing ensure the perfect air circulation without compromising on efficiency, but also combines a large enclosed stone space that provides an impressive löyly. The heaters efficiency ensures the sauna can get up to temperature in 40 mins – 1 hour, which is ideal for those who wish to improve their busy personal routines with sauna. As with all Narvi wood-burning sauna heaters, the Steam Master’s windowed door makes for an atmospheric sauna experience.

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

This heater requires up to 100kg of sauna stones. We recommend using 10-15cm Olivine Diabase or Vulcanite Sauna Stones for optimal performance.

The Steam Master is also available as a tunnel-equipped model that allows the heater to be fed from outside the sauna. Ideal for those who wish their sauna to serve solely as a place of relaxation.

• The glazed door hatch is an excellent choice for visibly ensuring an even flame distribution within the heater whilst also creating a pleasing 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, Aito and Kota 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 and their notable longevity be factored when comparing price.
