Description

The HUUM HIVE Flow LS is a 9.8 kW wood-burning sauna stove for rooms of 282–635 cubic feet. It holds 330 lb of stones, needs no electrical supply, and requires a code-compliant chimney.

HUUM's wood stoves are built around keeping heat in the room rather than sending it up the chimney — HUUM puts the figure at 75% of the fire's heat going into the sauna. They need no electrical supply at all, which is what makes them the answer for an off-grid cabin.

  • Mild and long-lasting steam
  • Innovative patent pending furnace construction
  • 330 pound stone capacity (required 10 boxes sold separately)
  • Dimensions: 20.7"W (526mm) x 29.5"D (750mm) x 34.8"H (884mm)
  • Limited 5-year warranty (excluding elements)

Sizing

The HUUM HIVE Flow LS is rated for 282–635 cubic feet.

Measure width × depth × height in feet. Add extra volume for anything that soaks up heat rather than reflecting it — glass, tile, concrete, stone and exposed log all make a room behave larger than its raw measurement. Size to the larger number: an undersized heater never gets the room right, and running it flat out shortens the elements.

Installation & Use Notes
  • Confirm your flue diameter and whether the chimney connects top or rear before ordering chimney components.
  • A solid-fuel appliance usually needs a permit and an inspection in the US, and your insurer will normally want to see the sign-off.
  • Burn the stove with the room ventilated for the first firing to cure the paint. Load stones loosely by hand and re-stack them once a year.
  • This is an LTL freight item. It arrives curbside on a pallet — note any damage on the delivery receipt before you sign.
FAQs

Does the HUUM HIVE Flow LS need electricity?

No. It is wood-fired and needs no electrical supply at all, which is what makes it work for an off-grid cabin. The trade-off is that you cannot preheat it remotely the way you can a UKU-controlled electric heater.

What does LS mean on the HUUM HIVE Flow LS?

The firebox extension passes through the sauna wall, so wood is loaded from the room next door. No smoke, ash or cold air enters the hot room. It needs a matching mounting collar to finish the wall penetration.

What is the HUUM HIVE Flow LS certified to?

HUUM lists it with Bimschv 2, CE marks. CE is the European conformity mark, and Bimschv 2 is the German wood-stove emissions standard. A solid-fuel appliance needs a permit and an inspection in most US jurisdictions regardless of the mark, so confirm with your building department and insurer before you install.
