HUUM and Harvia are leading sauna heater brands in the sauna world. One is rooted in minimalist Nordic design with a modern tech twist (HUUM), while the other is a time-tested Finnish brand trusted in saunas around the globe (Harvia). But picking the right one isn’t just about brand loyalty—it’s about what you want from your sauna experience.
In this guide, we compare HUUM and Harvia head-to-head – their design, performance, features, and value to help you decide which sauna heater truly fits your space, lifestyle, and expectations.
Overview of HUUM Electric Sauna Heaters
HUUM sauna heaters were founded in Estonia. These electric heaters offer a combination of traditional Finnish steam quality, sleek aesthetics, and smart technology. What sets HUUM apart is its focus on gentle, long-lasting heat.
Instead of relying on quick bursts of metal-generated warmth, HUUM heaters use a high volume of natural stones to slowly release soft steam, known as löyly in Finnish tradition. The result is a more authentic sauna experience that’s less drying and more relaxing.
Some of its top features are:
- Open stone baskets that improve air flow and heat retention.
- Minimalist, stainless-steel construction that complements modern sauna interiors.
- It is compatible with UKU smart controllers, including WiFi-enabled options for remote access.
- A focus on energy efficiency and sustainability, with precise temperature control.
The HUUM Electric Sauna Heater Models
HUUM offers a thoughtfully designed range of electric sauna heaters, each tailored for different room sizes, aesthetics, and user preferences.
HUUM Drop
The HUUM Drop heater stands out with its unique teardrop design. It’s a wall-mounted option, perfect for saunas where space is a priority.
Despite its compact size, the Drop holds up to 122 lbs of sauna stones, which is quite impressive. This high stone capacity allows it to create a gentle, long-lasting steam that mimics the feel of a traditional wood-burning sauna stove.
The result? You’ll get a soft, relaxing heat that doesn’t dry out the air or hit you too hard.
What makes the HUUM Drop stand out:
- Sleek, minimalist design that adds to your sauna’s aesthetic rather than taking away from it
- Wall-mounted installation, which keeps your floor space free and makes it an excellent choice for tighter layouts
- Durable stainless-steel body that resists corrosion and keeps its modern look over time
- Multiple power options (4.5 kW, 6 kW, 7.5 kW, and 9 kW) to suit saunas ranging from 106 to 530 cubic feet (3–15 m³)
- Compatible with HUUM’s UKU control systems, including WiFi, allowing you to control your sauna remotely via smartphone
HUUM Hive
If you aim to recreate the traditional sauna experience on a larger scale—with soft steam, stunning design, and rock-solid performance—the HUUM Hive is where it all comes together. As HUUM’s flagship model, it’s built for medium to large sauna spaces, including both residential and commercial settings.
The Hive isn’t just about heat—it’s about presence. Its cylindrical, open-basket design holds up to 550 lbs (250 kg) of stones, far more than most electric heaters on the market.
This generous stone volume allows the heater to produce soft, mild, and consistent steam that closely resembles the feel of a traditional wood-fired sauna—something sauna purists will immediately appreciate.
What makes the HUUM Hive special:
- Massive stone capacity for deep, even, and long-lasting heat
- Available in 12 kW, 15 kW, and 18 kW power options

Like its siblings, the Cliff is designed to deliver HUUM’s signature soft, consistent heat by relying on a generous volume of stones, rather than just metal heating elements.
One clever touch is the optional safety railing and embedding flange, which make the Cliff even easier to integrate into custom sauna bench designs while keeping safety in mind. The air tunnel built into its design also helps the heater warm up more efficiently, increasing durability by protecting the core heating elements.
Key Features of the HUUM Cliff:

Now, let’s compare them side by side to know which is best:
Aesthetics
HUUM heaters are known for their modern, minimalist designs. They integrate contemporary aesthetics that enhance the visual appeal of your sauna setup.
Models like the HUUM Drop heater, its teardrop shape, and the Hive series highlight innovative and award-winning design elements. These heaters suit modern and stylish sauna interiors.

Verdict:
If you’re designing a modern or high-end sauna space where visual impact matters, HUUM is the clear winner. Its sculptural, minimalist heaters perform well and double as design statements.
However, if you prefer a more classic or functional look or want a heater that blends seamlessly into a traditional sauna aesthetic, Harvia is the better fit. It’s practical, timeless, and versatile enough to suit almost any sauna environment.
Efficiency
HUUM heaters are designed to optimize energy use. Features like internal air tunnels reduce heating time by 25%, while their large stone capacity ensures even heat distribution. This design makes HUUM heaters suitable for sauna enthusiasts wanting consistent and efficient warmth.
Harvia Spirit 8kW Electric Sauna Heater
Harvia heaters are known for their operational efficiency and versatility. They have a wide range of models—including electric, wood-burning, and combi options—suitable for residential and commercial use.
The dual-wall construction in models like the KIP series improves heat retention and safety, improving overall energy efficiency.
Verdict:
If you're looking for long, consistent heat with lower energy spikes, HUUM is the better pick due to its smart engineering and stone-based heat retention.
But if you value quick heat-up times, a wide range of heater sizes, and flexibility across sauna types, Harvia takes the lead with its adaptable, performance-driven lineup that efficiently serves residential and commercial users.
Features
HUUM offers smart controls for the ultimate sauna experience. Most of their electric heaters are compatible with the UKU control system, including WiFi and mobile app control options.
This allows you to preheat your sauna remotely, set timers, and monitor temperature—all from your phone.
Harvia focuses on reliable, user-friendly features. Whether you prefer manual knobs, digital interfaces, or remote control panels, Harvia offers a wide range of user-friendly features across its models.
The Harvia Spirit, for example, supports smart safety sensors and is compatible with Xenio control systems for programmable operation. While not as sleek or app-centric as HUUM, Harvia’s approach to features prioritizes reliability, accessibility, and ease of use.
Verdict:
If you're after cutting-edge smart functionality and want to control your sauna experience from anywhere, HUUM leads with its integrated tech and mobile connectivity.
But if you prefer straightforward, dependable controls with options to suit various preferences—from manual to digital—Harvia wins for a practical, no-fuss operation that still does the job beautifully.
Sustainability
HUUM applies eco-friendly practices in its heater designs. By using sustainable materials and creating energy-efficient heaters, HUUM aligns itself with environmentally conscious sauna lovers. For instance, its high stone capacity reduces the need for frequent reheating, which helps lower overall electricity consumption.
Harvia heaters are built from durable stainless steel, minimizing the environmental impact of replacement or repair. HUUM's minimalist design also means fewer moving parts and less waste over time.
Harvia also demonstrates a commitment to sustainability. They produce high-quality sauna heaters designed to perform efficiently over time, reducing the frequency of replacements. If you value longevity and reliable craftsmanship, Harvia is an excellent choice.

Both brands show strong sustainability values but in different ways. HUUM is ideal for those prioritizing low energy consumption and long-term efficiency, especially in electric models with smart controls.
Meanwhile, Harvia stands out for its broad commitment to sustainable manufacturing.

However, if you're looking for reliable performance at a more accessible price point, Harvia offers a variety of models to suit different needs and budgets.
Heating Time
HUUM heaters have faster heating capabilities due to innovative air tunnel designs, which improve airflow and speed up heating time by 25%. Their large stone capacity contributes to prolonged steam sessions, recreating the warmth of a traditional Finnish sauna.
