HUUM Wood Burning Heater Packages

Why Buy the Package Instead of the Bare Stove

A wood-burning sauna stove is only half the install. The other half is the chimney — and that's where most first-time buyers stall, because a wood stove can't run safely without the right flue kit for your specific roof or wall configuration. These packages solve that. Each one pairs the HUUM stove with a chimney kit (and stones where noted), so you order one bundle instead of trying to spec the flue components yourself.

The chimney kit options across these packages cover the common configurations: Thru-Wall, Thru-Wall Backside, Barrel, Thru-Flat or Curved Ceiling, and Thru-Angled Ceiling. You pick the path your chimney takes out of the sauna, and the kit comes matched to it. If you'd rather buy the stove on its own, you'll find the bare units in the HIVE Wood stove collection and the HIVE Flow stove collection — but for most builds, the bundled package is the cleaner order. If you're still weighing wood against electric, the full HUUM electric heater range sits alongside these in the complete sauna heater lineup.

The Off-Grid Advantage

A wood-burning sauna needs no electrical service — no dedicated 240V circuit, no breaker, no electrician for the heater itself. That's the whole appeal. If you're building a cabin off the grid, a lakeside sauna with no power run, or you just want the ritual of a real fire, wood is the answer. If a power run isn't an issue and you'd rather skip fire-tending, the HUUM electric heater packages bundle a controller and stones the same way these bundle a chimney. The trade-off with wood is that you're tending a fire instead of tapping a phone app, and you need a code-compliant chimney with proper clearances to combustibles. The foundation, venting, and clearance work still warrants a professional eye — our sauna installation and electrical guide covers the planning side, and you should always consult a licensed professional for chimney and clearance requirements, which vary by local code.

Sizing by Cubic Footage

Wood stoves are sized to room volume the same way electric heaters are — match the stove's rated range to your sauna's cubic footage. Across these packages the coverage runs from about 212 cu ft on the small end up to 635 cu ft on the large end, so there's a stove for everything from a compact 2–3 person room to a big outdoor cabin.

• HIVE Flow Mini 8.5kW — 212–494 cu ft, 231 lbs of stones, takes a 12" log. The smallest of the group and the easiest to feed.
• HIVE Wood 13kW — 212–459 cu ft, 199 lbs of stones, interior feed.
• HIVE Flow 9.8kW — 282–635 cu ft, 330 lbs of stones, takes a 16" log. The biggest stone mass and the widest coverage in the lineup.
• HIVE Wood 17kW — 283–565 cu ft, 287 lbs of stones, interior feed. The hottest output for big rooms.

When you're between two sizes, size up — glass doors, tile, and cold exterior walls all pull effective capacity down, and an undersized stove never quite gets a big room to temperature.

Interior Feed vs. LS (Through-the-Wall) Feed

Every HUUM wood stove comes in two feed styles, and choosing the right one is a build decision you make before the walls go up. The standard version loads from inside the sauna — you open the door, add a log, close it, all from the hot room. The LS version feeds through the wall: the firebox door sits on the outside of the sauna, so you load wood from an adjacent room, a porch, or the changing area without bringing cold air and bark into the hot room.

LS is the move when you don't want to tend the fire from inside the sauna — common in outdoor cabins where the loading door faces a covered porch, or in builds where you'd rather keep the firewood and ash outside the bathing space entirely. The packages offer LS versions of the bigger stoves: HIVE Wood LS 17kW, HIVE Flow LS 9.8kW, and HIVE Flow Mini LS 8.5kW. The LS Flow models include a protective bed accessory and use a mounting collar at the wall pass-through. Decide interior vs. LS early, because it changes how you frame the wall.

HIVE Wood vs. HIVE Flow

HUUM makes two wood-stove families, and they're built around different priorities. The HIVE Wood is the wood-burning version of HUUM's iconic HIVE cylinder — the same cage-of-stone look, in 13kW and 17kW. It runs hotter per unit (up to 17kW) for big rooms and pushes more raw output. Think of it as the high-heat option with the classic HIVE aesthetic.

The HIVE Flow is HUUM's newer wood line, with a taller body (about 34.8" high) and — this is the key difference — a bigger stone mass at a lower kW rating. The Flow 9.8kW carries 330 lbs of stones, more than either HIVE Wood, despite a lower power number. More stone mass means softer, more sustained löyly and a gentler heat curve, even though the headline wattage is lower. So the choice isn't "more powerful vs. less powerful" — it's two different heat characters. Pick HIVE Wood for maximum raw output and the classic cage look; pick HIVE Flow for the best löyly-per-kW and a more even, stone-driven heat. For buyers who want the same cage-of-stone look on a circuit instead of a fire, the electric HIVE covers the bigger electric rooms.

What's in Each Package

Each package includes the stove and a chimney kit in the roof or wall configuration you select; stones are included where noted on the individual product. The chimney kit covers the flue components for your chosen path out of the sauna. What you'll still want to confirm separately: the right volume of sauna stones if your chosen package doesn't bundle them, a water bucket and ladle, and any clearance shielding your local code requires. If you're comparing these against the rest of the category, the broader wood-burning sauna heaters collection shows where HUUM sits next to other brands, and the Harvia wood-burning packages are the closest competing bundles if you're weighing brands.

How to Choose

Work in this order. First, room volume — find the stove whose cu ft range covers your sauna, sizing up if you're on the line. Second, feed style — interior if you'll tend the fire from inside, LS if you want the loading door outside the hot room. Third, heat character — HIVE Wood for maximum output and the classic cylinder, HIVE Flow for more stone mass and softer löyly. Fourth, the chimney kit — select the configuration that matches how your flue exits the building. Get those four right and the package handles the rest.

HUUM's warranty is valid only through authorized dealers like Topture — grey-market stoves from third-party resellers often aren't covered even when the product looks identical. We're an authorized HUUM dealer, ship every package free, and our team's available if you hit a question on sizing, feed style, or chimney configuration during your build.
