Best wood-fired sauna heaters

Use your sauna’s volume to narrow the list rather than choosing by output alone. The Narvi NC 16/20/24 Wood Burning Sauna Heater is listed at 7.5 kW for rooms of 10–24 m³. The Harvia Wood Burning Sauna Stove is listed at 12 kW for 10–25 m³. Their room ranges overlap, though their stated outputs differ.

For smaller listed volumes, the Harvia Legend 150 SL black covers 6–13 m³ at 16 kW. The Harvia Pro 20 SL Wood Burning Stove - Black covers 8–20 m³ at 24.1 kW. The Huum Hive Wood 17 kW LS has a listed output of 17 kW, but no usable room-volume range is supplied. If you are considering it, confirm the suitable room volume before making your choice.

The Narvi has the lowest starting price at £860. Next is the Harvia Wood Burning Sauna Stove at £999, followed by the Harvia Legend 150 SL at £1,184.88. The Huum Hive Wood 17 kW LS starts at £1,269, and the Harvia Pro 20 SL starts at £1,330. Each price comes from one shop checked, so treat these as listed starting prices rather than a broad market comparison.

The Legend 150 SL and Huum Hive Wood 17 kW LS are both named as through-the-wall models. The Harvia Wood Burning Sauna Stove lists manual controls, while the Pro 20 SL lists controls on the heater. Control details are not supplied for the other three models.
