Description

HUUM Hive Flow LS Through-the-Wall Wood-Burning Sauna Stove (9.8 kW)

The Hive Flow LS is HUUM's cleanest-burning wood stove, with a gorgeous view of the fire. The firebox passes through the wall so you light and load it from your lounge or changing room, with a big glass door to enjoy the flames, while the stone-filled Hive cage heats the sauna on the other side.

Its 150 kg of stones give deep, soft heat for saunas of 8 to 18 m³. Designed and made in Estonia.

Choose your package

Stove only The stove. You'll need your own chimney, floor protection and stones
Complete set Stove, chimney and front floor plate. Add stones, and check the floor under the stove (see below)

What's in the complete set

  • HUUM Hive Flow LS 9.8 kW through-the-wall stove, with grate, ash drawer, cleaning hatches and heat-resistant glove
  • Harvia WHP1500 black insulated chimney set (Ø115 mm): 1.5 m insulated stainless steel chimney, 1 m flue pipe, ceiling lead-through, rubber roof flashing and rain cap
  • Harvia WL260 floor protection plate (800*400 mm) for in front of the fire door

Recommended stones (not included)

The Hive Flow takes 150 kg of stones. HUUM recommends round stones.

Can I put it straight into my sauna?

Almost. Check these before you order:

  • Non-combustible base under the stove (not included): HUUM requires a concrete floor at least 50 mm thick. On a timber floor you'll need HUUM's thermal plate (or another non-combustible base) with a 30 mm ventilation gap underneath, which we can quote for you
  • Non-combustible wall section (not included): the firebox passes through a non-combustible wall, built to the minimum dimensions in HUUM's manual. Leave at least 50 mm between the stove and any non-combustible wall
  • Front floor protection: on a timber floor, a metal plate at least 400 mm deep and 100 mm wider than the door on each side (the WL260 in the set covers this)
  • Chimney: T450 rated or better, Ø115 mm. The set suits a standard install through one ceiling and roof; taller rooms may need an extra WHP500 / WHP1000 section
  • Stones: as above

Installation

  • Installer: the stove and chimney must be installed following HUUM's manual (downloadable below) and the safety distances in the specifications.
  • Ventilation: a fresh-air inlet low down near the stove and an outlet high up on the far side of the room, as shown in the manual.

Why you'll love it

  • Clean-burning firebox, certified to strict German BImSchV II emission limits
  • Fire on show outside the sauna, with no wood or ash in the hot room
  • 150 kg of stones for soft, even löyly
  • Distinctive HUUM design
