The HUUM HIVE Flow is one of the most efficient wood sauna stoves made. Its patent-pending firebox sends about 75% of the heat from the firewood into the sauna instead of up the chimney, so you burn less wood and get mild, long-lasting steam from a big stone load. Choose the Flow Mini (8.5 kW) or Flow (9.8 kW), and the LS versions with an extended firebox to load wood from outside the sauna.
Why people pick it

Common questions
What does LS mean?
LS models have an extended firebox, so you load wood through the wall from outside the sauna.
How many stones does it take?
Seven 33 lb boxes for the Flow Mini and ten for the Flow.
What chimney works with this stove?
HUUM discontinued its own chimney kits, so we offer Harvia chimney kits, extensions and smoke pipe as options on this page. They fit the HIVE's 115 mm flue. Call us and we will help you pick the right setup for your ceiling or roof.
How long until it ships?
Lead times vary by model and season. We confirm the timeline when you order and contact you before it ships.
Will this heater fit my sauna?
Heaters are sized by the volume of the sauna room. Check the room size range in the specs above, or send us your sauna's inside dimensions and we'll confirm the right size.
Does a wood heater need electrical?
No. Wood-burning heaters need no power. You do need a proper chimney and the clearances listed in the manual.
Can I pay over time?
Yes. Choose Affirm or Klarna at checkout to split your order into monthly payments, subject to approval.
What about the warranty?
It's covered by the manufacturer's warranty. You don't have to deal with the brand yourself. Call us and we handle the claim for you.
