HUUM vs Harvia Sauna Heaters: How They Compare (2026)
Harvia and HUUM are the two heater brands people compare most often, and they could hardly be more different. Harvia is the Finnish maker with a heater for almost every room, from a 120V compact to a commercial wood stove. HUUM is the Estonian brand known for its sculptural designs and its heaters packed with stones.
Neither is better in general. Each is better for certain rooms and certain people. Here is how they compare, with the real specifications and prices of the heaters we sell.
The short answer

What sets Harvia apart
The widest range. Harvia covers rooms from 70 cubic feet with the Vega Compact to more than 1,200 cubic feet with the Pro 36 wood stove, and makes a 40 kW stove, the Harvia 50, for commercial saunas. If your room is unusually small or unusually large, Harvia is likely to have a model for it.
A heater for a standard outlet. The Vega Compact 1.9 kW runs on 120V. It is the only electric heater in either range that does not need a 240V circuit, which makes it the simplest choice for a small sauna where running a new circuit is difficult.
Controls built in. The Vega, the KIP series and the Cilindro PC90 have their controls on the heater itself. You set the time and temperature on the heater, with no separate control unit to buy or install. The Spirit, the Cilindro PC60E and PC80E and the Virta need a separate Xenio or Fenix control.
Heat and steam in one unit. The Virta Combi heaters add a steam generator to a sauna heater, so the same room can work as a dry sauna or a humid steam room. HUUM has no equivalent in our range.
A large stone mass when you want it. Harvia heaters are not all small stone-holders. The Cilindro pillar heaters take 200 lbs of stones in a tall column, for a softer and longer-lasting steam.
What sets HUUM apart
The design. HUUM heaters are made to be looked at. The DROP is a wall-mounted water-drop shape, the HIVE Mini a round floor heater, and the CORE can be fully embedded in a sauna bench. If the heater is the centerpiece of your sauna, this is what most people notice first.
A lot of stone. A HUUM DROP holds 122 lbs of stones, a CORE 66 lbs and a HIVE Mini 330 lbs, all in direct contact with the heating elements. HUUM's point is that more exposed stones create a longer and milder heat. For comparison, a Harvia KIP holds 44 lbs.
One control, many finishes. Every HUUM electric heater runs with the UKU control. It sets the temperature from 104 to 230°F and can delay the start by up to 48 hours. It comes as a Local version or a Wi-Fi version for the HUUM app, in black, wood, glass, gold or mirror finishes. Our packages let you choose, and the price changes with the version.
A longer warranty. HUUM electric heaters carry a 3-year limited residential warranty and a 1-year commercial warranty, with the heating elements excluded, and the HIVE Wood stoves a 3-year residential warranty. Most Harvia heaters carry a 1-year consumer warranty. Read both warranty documents on the product pages before you decide on this point alone.
Electric heaters, side by side
The fairest way to compare is room for room, package for package. Both brands' packages below include the heater, its stones and the control it needs.
| Room size | Harvia | HUUM |
|---|---|---|
| Small room | KIP45B package, 4.5 kW, 100 to 210 cu ft, built-in controls, 44 lbs of stones: $1,348.89 | DROP 4.5 package, 4.5 kW, 106 to 248 cu ft, UKU control, 132 lbs of stones: from $2,716 |
| Larger room, Wi-Fi control | Spirit SP90E package, 9 kW, 177 to 494 cu ft, Xenio CX45 Wi-Fi control, 132 lbs of stones: $4,033.33 | DROP 9 package, 9 kW, 283 to 460 cu ft, UKU Wi-Fi control, 132 lbs of stones: from $3,395 |
Prices as of November 2026.
The result is not one-sided. In a small room, Harvia is about half the price, mostly because the KIP needs no separate control. In a larger room with Wi-Fi control, the HUUM package costs less than the Harvia one.
Wood-burning stoves, side by side
| Harvia M3 | HUUM HIVE Wood 13 | |
|---|---|---|
| Power | 16.5 kW | 13 kW |
| Room size | 212 to 459 cu ft | 212 to 459 cu ft |
| Stones | 66 lbs | 199 lbs |
| Price, stove alone | $1,076.67 | $2,150 |
Prices as of November 2026.
Both stoves heat the same size of room. The Harvia M3 costs about half as much and also comes as a complete package with its floor protection, chimney and stones. The HIVE Wood holds three times the stones, in HUUM's signature shape. Both brands also make versions with an external firebox, the Harvia M3 SL and the HUUM HIVE Wood LS 17, so the fire can be fed from the next room.
Which one should you choose?
- A small sauna, or no 240V circuit available: Harvia. The Vega Compact 1.9 kW runs on 120V, and the Vega and KIP need no separate control.
- The lowest price for a complete, working heater: Harvia. The Vega BC35 package starts at $1,050 with its stones.
- The heater as a design piece, and a large mass of stone: HUUM. The DROP, HIVE Mini and CORE are built around it.
- App control in a medium or large room: compare both. As the table above shows, HUUM can cost less once Wi-Fi is included.
- Sauna and steam room in one: Harvia's Virta Combi.
- A very large or commercial sauna: Harvia, with the Pro stoves and the Harvia 50.
- The longest warranty: HUUM, with 3 years residential.
Whatever the brand, size the heater to your room first. A beautiful heater that is too small or too large will never feel right.
Common questions
Is HUUM better than Harvia?
Neither is better across the board. Harvia has the wider range, built-in controls and the lower entry prices. HUUM has the design, more stone per heater and a longer warranty. The right one depends on your room and what you value.
Do HUUM heaters need a separate control?
Yes. Every HUUM electric heater works with the UKU control. Our HUUM packages include it, in the version and finish you choose.
Can I use Harvia stones in a HUUM heater?
Use the stones each manufacturer specifies: HUUM's rounded stones for HUUM heaters, and the Harvia stone listed for each Harvia model. Our sauna stones guide gives the type and quantity for each heater.
Which brand heats faster?
Heat-up time depends on the room, its insulation and the heater size much more than on the brand. HUUM notes that the air tunnel of the HIVE Mini shortens its heat-up time.
Where are they made?
Harvia heaters are designed and made in Finland, HUUM heaters in Estonia.
