HUUM HIVE Wood 17 kW Sauna Stove: Quick Answer

The HUUM HIVE Wood 17 is an Estonian stainless-steel wood sauna stove rated at 17 kW, sized for an 8-to-16-cubic-meter room, with a 130 kg stone capacity, a 115 mm flue outlet, and a 3-year residential warranty, priced at $2,670 at research time. It is the larger sibling of the HIVE Wood 13 and, like it, publishes a complete official spec table — every figure below comes from the HUUM spec sheet, not just the listing. The trade-off is price and weight: at $2,670 and 65 kg empty, it is the heaviest and most expensive stove in our roster.

What Do You Get in the HUUM HIVE Wood 17?

A stainless-steel wood sauna stove rated at 17 kW, with a 130 kg stone capacity, a 5 mm flame tamer, a natural-oil finish, and a full official specification sheet. The HUUM product page retrieved August 25, 2026 publishes the complete spec table: 17 kW output, an 8-to-16-cubic-meter room range, 130 kg of stones, a 65 kg stove weight, dimensions of 750 mm tall by 555 mm wide by 590 mm deep, a 115 mm flue diameter, and a 400 mm maximum firewood length. The Amazon listing corroborates the stone load (286 lb) and room range.

The 130 kg stone capacity is the defining feature and the largest in our roster. Stones are the thermal mass that turns a wood fire into the soft, even heat of a proper sauna, and 130 kg is a serious load — enough to hold temperature through long gaps between firewood loads and to produce a deep, gentle steam when you throw water. For a larger sauna, that stone mass is what separates a real sauna experience from a hot room.

The 5 mm flame tamer is the construction detail worth noting. It is a thick steel plate inside the firebox that shapes the flame and protects the stove body from direct flame impingement, which extends the life of the steel and evens out the heat. Combined with the stainless body and natural-oil finish, it signals a stove built for years of daily use.

Why Does the 17 kW Step Up Matter?

Because the 17 kW model covers a larger room band than the 13 kW, and the extra stone mass changes the sauna experience itself. The HIVE Wood 17 is sized for 8 to 16 cubic meters — roughly 283 to 565 cubic feet — which is the band for a large home sauna or a small club sauna. The 13 kW model tops out at 13 cubic meters, so if your room is between 13 and 16 cubic meters, the 17 is the correct size and the 13 is undersized.

The stone mass is the other step up. 130 kg versus 90 kg is a 40 kg difference in thermal mass, which means the 17 kW stove holds heat longer and produces a softer, more even steam. The firewood length also steps up to 400 mm, so you can burn longer logs and reload less often. The flue diameter stays at 115 mm, so the chimney sizing is the same as the 13 kW model.

How Does the HUUM HIVE Wood 17 Compare With Other Wood Stoves?

| Product | Output | Room range | Stones | Price (research time) | |---|---|---|---|---| | HUUM HIVE Wood 17 | 17 kW | 8–16 m³ | 130 kg | $2,670 | | HUUM HIVE Wood 13 | 13 kW | 6–13 m³ | 90 kg | $2,530 | | Harvia M3 | 16.5 kW | 212–459 cu ft | included | $1,100 | | Harvia Legend 16 kW | 16 kW | not published | 4 boxes | $1,752 | | Harvia Pro 20 | 20 kW | 283–706 cu ft | 1 box | $1,745 |

The HIVE Wood 17 is the large-room documentation leader. It publishes its complete official spec table — power, room range, stone mass, weight, dimensions, flue diameter, and firewood length — where the Harvia steel stoves publish only listing figures and the Legend omits its room range entirely. Against the Harvia Pro 20, it gives up 3 kW of output but carries 130 kg of stones versus the Pro 20's single box, and it publishes the flue and firewood data the Pro 20 omits. The price reflects the documentation: at $2,670 it is the most expensive stove in the roster.

Rating Breakdown (Spec-Based Evaluation)

| Dimension | Score | Justification | |---|---|---| | Heat performance | 5/5 | 17 kW with a 130 kg stone capacity and a 5 mm flame tamer — the largest documented stone load in the roster. | | Build quality | 5/5 | Stainless-steel body, 5 mm flame tamer, and natural-oil finish, backed by a 3-year residential warranty. | | Value | 4/5 | $2,670 is the highest price in the roster, but full official documentation and the largest stone load justify it. | | Assembly | 3/5 | Floor-standing at 65 kg empty, plus chimney connection and 130 kg of stone loading — the heaviest install in the roster. |

Pros and Cons

| Pros | Cons | |---|---| | Full official spec table: power, room range, stone mass, flue, firewood length. | $2,670 is the highest price in our wood-stove roster. | | 130 kg stone capacity — the largest documented load in the roster. | 65 kg empty weight plus 130 kg of stones is a heavy install. | | 8–16 m³ room range covers large home and small club saunas. | Floor-standing; chimney and stones are separate install work. | | 400 mm firewood length means fewer reloads. | 17 kW is oversized for small home saunas. | | 3-year residential warranty (1-year commercial). | Higher price than the Harvia Pro 20 for less output. |

What Should You Verify Before Buying?

Confirm your room is within 8 to 16 cubic meters, and confirm your chimney matches the 115 mm flue outlet. Measure length, width, and ceiling height in meters; if the room is below about 8 cubic meters, the HIVE Wood 17 is oversized and the HIVE Wood 13 or a smaller stove is the better fit. If it is above 16 cubic meters, you need a commercial-class unit. Cut your firewood to a maximum 400 mm length so it fits the firebox.

Also plan the install as a heavy one. The stove weighs 65 kg empty and takes 130 kg of stones, so the floor base must be level and non-combustible, and you will likely need two people to position it. Load the stones correctly around the firebox for even heat. The 3-year residential warranty applies to residential use — commercial installs get 1 year.

Verdict

The HUUM HIVE Wood 17 is the large-room documentation leader of our wood-stove roster — a 17 kW stainless-steel stove with a 130 kg stone capacity, a 5 mm flame tamer, and a complete official spec table, at $2,670. If you have a large home sauna or a small club sauna in the 8-to-16-cubic-meter band and want a stove you can spec, quote, and install without guesswork, it is the strongest pick in the roster. If budget is the binding constraint, the Harvia Pro 20 delivers more output for less, but without the published flue, stone-mass, and firewood-length data.
