If you are choosing between these two, start with Huum if design and app control are high on your list and you want a heater that looks intentional in the room. Choose IKI if you mostly care about loyly and want the large stone mass a pillar heater gives you.
This comparison matters because both are premium European heaters that get cross-shopped, but they are built around different priorities. Huum is an Estonian, design-led brand founded in 2011. IKI is a Finnish pillar-heater maker with a cult following among serious sauna builders, founded in Finland in the late 1980s.

Quick Comparison
| Factor | Huum | IKI |
|---|
| Built around | Design and smart app control | Stone mass and loyly quality |
| Format | Sleek stone-clad heaters (DROP, HIVE) | Tall pillar with large visible stone load |
| Best for | Buyers who want the heater to look like furniture | Buyers who want soft, long-lasting steam |
| Watch for | Premium pricing, wear parts excluded from warranty | Pillar layout needs space, sourcing varies by market |
| Default recommendation | Huum if design and control lead | IKI if loyly leads |
Huum
Huum is the easier pick when you want the heater to be part of the room, not just a heat source. The DROP and HIVE designs are made to show the stones, and Huum was an early mover on mobile sauna control through its UKU WiFi controller and app. If you want to start the sauna from your phone and have it look clean on the wall, this is a real strength.
Huum heat is described by the maker as soft and even, drawing on Estonian sauna tradition. The smart control is genuinely useful if your routine benefits from remote start.
Honest tradeoffs: Huum sits at premium pricing relative to mid-range Finnish heaters. The Huum limited warranty (v5, January 2025) covers heaters and control units for 3 years in private use, but heating elements, stones, and sensors are excluded as wear items. Budget for replacement parts over the life of the heater. Dealer support is strongest in Europe, so confirm shipping, installation support, and service before ordering outside that market.
IKI
IKI is the stronger pick when loyly is the point. The signature IKI Pillar stacks stones vertically in a tall steel mesh body, which holds a large stone mass relative to its footprint. More hot stone generally means softer, longer-lasting steam and a more forgiving heat profile than many compact electric heaters. That is why IKI has a cult following among people who care more about how the sauna feels than about convenience features.
Honest tradeoffs: the pillar format needs thoughtful placement, so it is not ideal for every small-room layout. Check clearances and bench layout early. IKI is premium-priced, and you should budget for a premium stone load and freight on top of the heater. Sourcing and warranty support depend heavily on market and distributor. In Europe the support path is straightforward. Outside Europe, confirm parts, service, and local code approval before you plan around it.
Our Take
If design, a clean look, and phone control are what you keep coming back to, choose Huum.
If you are building for loyly and have the space and budget for a pillar heater with a big stone load, choose IKI.
Neither is a downgrade. They are optimized for different things. The mistake is buying the design story when you really wanted the steam, or buying the pillar when your room cannot accommodate it.
FAQ
Is Huum or IKI better for loyly?
IKI is generally the stronger loyly choice. The tall pillar holds a large stone mass, which tends to give softer, longer steam. Huum also delivers soft heat with good stone capacity in models like HIVE, but loyly is IKI's core focus.
Does Huum really have app control and IKI does not?
Huum was an early mover on mobile sauna control with its UKU WiFi controller and app. If remote start from your phone matters, that is a clear Huum advantage. Always confirm the exact controller and connectivity for the specific model and region with the dealer.
How much do Huum and IKI heaters cost?
Heater pricing is dealer and region driven for both brands, and both sit in the premium tier. Get a quote from a local dealer that includes the heater, the full stone load, controls, and freight. Confirm current pricing by region and dealer rather than relying on a single online figure.
Can I get IKI and Huum easily outside Europe?
Both are Europe-focused. Huum has a wider dealer network but is still strongest in Europe. IKI sourcing and support vary by distributor. Before planning around either outside Europe, confirm shipping, installation support, parts, and local code approval.
