Wood Sauna Heaters
Size a wood stove by the volume of the hot room, so measure it in cubic feet before you look at anything on this page. The HUUM HIVE Wood and Flow families start at 212, the Harvia Legend 240 GreenFlame covers up to 848, and the 50 kW Narvi 50 fills 2,500.
Stone mass is the next number, and it is the one that decides how the heat actually feels. Too few stones and the room comes up fast but harsh. Too many and it can take hours to get there. A HIVE Wood carries 199 to 287 lb of stones; a Narvi Kaamos 20 carries 132. That spread is the difference between a quick evening sauna and a Saturday you plan around.
Plan the chimney and the stones with the stove, not after it. Stones and a code-compliant chimney system are required and sold separately on the HUUM HIVE Wood, and Harvia rocks can only be bought alongside a heater, so both belong on the same order. The tent stove is the exception, shipping with a complete chimney set.
To feed the fire from the next room and keep the wood, the mess and the cold draught out of the hot room, look at the HIVE Wood 17 LS, the Harvia Pro SL, or the Harvia Duo, which is a fireplace on the other side of the wall.

Harvia 50 Wood-Burning Sauna Stove | 40 kW Commercial Heater (WK500)
$7,587.00Forty kilowatts is not a home number. The Harvia 50 is what large public rooms get built around: 706 to 1,766 cubic feet of sauna, 264 pounds of stones in the basket, and enough mass to hold the room when a full bench keeps throwing löyly. Black steel, floor-standing, 428 pounds empty, with a 5.5 inch flue collar that can exit the back or the top. Two things are worth settling before you order, and we would rather settle them with you than let a cart guess: the stones are required and sold separately, and the 50 does not share a chimney or a protective sheath with the rest of the Harvia wood line.
