HUUM Hive Flow: a wood sauna stove that sends three quarters of the fire’s heat into the room
The HUUM Hive Flow is a floor standing wood burning sauna stove made in Estonia, rated at 9.8 kW for rooms from 282 to 635 cubic feet. About 75 percent of the heat from the firewood goes into the sauna instead of up the chimney, which means less wood for the same heat and milder, longer lasting steam. The stove is about 21 inches wide, 25 inches deep, and 35 inches tall. It weighs 148 pounds empty, takes logs up to 16 inches long, and holds 330 pounds of stones. The flue can exit from the top or the back, and the stove needs a ceiling at least 75 inches high.
The box holds the stove, a metal grate, an ash grate and ash drawer, two cleaning hatches, two fixing plates, splints, a heat resistant glove, and the manual. Sauna stones are sold separately, so add the 10 boxes it needs on the page. A chimney is not included, so pick the through the ceiling, through the wall, or barrel sauna chimney kit on the page. A floor plate, protective bedding, a stone cage, and a bucket and ladle set are optional there too. Want to feed the fire from the next room? See the HUUM Hive Flow LS with firebox extension. The HUUM Hive Flow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What sets the HIVE Flow apart from other wood stoves?

What size room is it rated for?
Sauna rooms from 282 to 635 cubic feet with a minimum room height of 75 inches, per the specification table – the full-size model in the HIVE Flow line, above the two 8.5kW Mini versions.
How is it vented?
Through a chimney at the top or back flue connection, per the specification table. The Operating Accessories add-on on this page offers HUUM chimney kits for thru-ceiling, thru-wall, and barrel sauna installations, so venting can be ordered alongside the stove.
