Huum Drop Electric Sauna Heater Review: Is It Worth the Money?
If you are spending a lot of money on a home sauna, the heater is not the place to cut corners. It determines the quality of every single session you...
How the HUUM Hive Series Delivers Richer Steam
The HUUM Hive line stands out because stone capacity is built into the core concept rather than treated as an afterthought. The beehive-inspired design holds 250 kg of sauna stones, producing gentle, rich steam across longer sessions.
That stone mass acts as a thermal battery, absorbing energy steadily and releasing it in soft, even waves rather than sharp bursts of dry heat. For home saunas and commercial wellness spaces alike, this means fewer temperature swings and a more consistent experience from start to finish.
If you have ever stepped into a sauna and found the air uncomfortably arid within the first ten minutes, a low stone load is usually the culprit. The Hive design addresses that directly.
Who the HUUM Hive Series is For
The Hive collection suits buyers who prioritize steam quality over compact form.
- The heaters are physically substantial, which means they work best in dedicated sauna rooms where aesthetics and performance are both part of the brief.
- Residential buyers finishing a custom sauna build and commercial operators outfitting a spa or wellness facility will find the most value here.
- If your sauna room is smaller or you are working with tight installation constraints, a different HUUM line may be the better starting point. The Hive rewards space and proper planning.
Stone Capacity and Heat Quality
The relationship between stone volume and steam character is straightforward. More stones absorb more energy, retain heat longer, and release moisture gradually when water is poured over them. The result is löyly, the Finnish term for the steam created by pouring water over hot sauna stones, that feels full-bodied rather than sharp.
With up to 250 kg of stones, the Hive produces löyly that hangs in the room rather than dissipating immediately. That lingering quality is what creates the enveloping sensation experienced in traditional Finnish and Estonian saunas, and it is what separates the Hive Series from most electric heaters on the market for buyers who take sauna culture seriously.
Design Aesthetics and Build Quality
The beehive silhouette is not decorative camouflage for standard components. The shape directly supports the stacked stone arrangement, allowing more stones to sit in stable contact with the heating elements. The result is a heater that looks distinctive and performs better precisely because of its shape.
HUUM builds the Hive series with materials that hold up in high-humidity, high-heat environments over years of regular use. For buyers who want a heater that brings the character of a wood-fired sauna to an electric unit, while remaining a focal point rather than a utilitarian box in the corner, the Hive delivers on both counts.
HUUM Hive Series Sizes
Hive models are sized to match different room volumes, so the right choice depends on the cubic footage of your sauna. An undersized heater limits performance regardless of stone capacity, while an oversized unit cycles inefficiently in a smaller room.
Use room dimensions as your first filter, then match the model to your power supply and control preferences. The collection available through Heracles Wellness covers the core Hive lineup as well as the HUUM Hive Mini Series, making it straightforward to compare models side by side before making a purchase.
HUUM HIVE 12 kW
For larger home saunas or shared spaces serving multiple bathers, the 12 kW configuration is the choice most serious buyers settle on.
The heater's components are constructed from durable stainless steel, and the round form factor allows central placement rather than requiring a flush wall mount. That positioning advantage is meaningful for group or family use, where heat distribution matters as much as raw output. A centrally placed heater reaches bathers from all sides rather than radiating primarily in one direction.
This model suits buyers with saunas in the 424 to 636 cubic foot range, households with multiple regular users, or anyone building a dedicated sauna room where performance consistency is the priority.
HUUM HIVE 15 kW
The 15 kW model bridges the gap between the mid-range 12 kW and the top-tier 18 kW, making it the right choice for larger dedicated sauna rooms that regularly host multiple bathers. It is particularly well suited to saunas in the 530 to 813 cubic foot range, where a 12 kW unit would be operating near its maximum capacity and an 18 kW unit would be more than the space requires.
Like all Hive models, the 15 kW carries the full stone capacity and stainless steel construction of the series. The increased output means faster preheat times in larger rooms without sacrificing the dense, sustained steam the Hive is known for.
For commercial wellness operators or homeowners building a generously sized sauna room, this configuration offers a strong balance of performance and efficiency.
HUUM HIVE18 kW
The 18 kW is the highest-output model in the Hive Series and is built for large commercial installations, spacious residential sauna rooms, or any setting where consistent heat across a significant cubic volume is non-negotiable. It is best matched to rooms in the 636 to 989 cubic foot range, where lower-output configurations simply cannot maintain the temperature and steam quality that serious sauna users expect.
At this output level, the Hive's 250 kg stone capacity is especially impactful. The combination of high wattage and maximum stone load means the heater can absorb and release substantial thermal energy, producing löyly that fills a large room without thinning out. For spa facilities, wellness centers, or custom residential builds where performance is the defining requirement, the 18 kW Hive is the definitive choice.

Frequently Asked Questions
How many sauna stones does the HUUM Hive hold?
The Hive is engineered specifically around stone capacity. According to HUUM's own product documentation, the heater holds up to 250 kg of sauna stones, an unusually high amount for a residential electric unit. That volume allows the Hive to produce the gentle, layered steam that feels closer to a traditional wood-fired experience than most electric heaters can manage.
Is the HUUM Hive a good fit for home saunas?
It depends on room size. The Hive lineup covers a range of kilowatt outputs, so there is a configuration suited to smaller home saunas as well as larger installations. The key is matching the heater's output to your room's cubic volume. The collection page at Heracles Wellness includes multiple Hive models, making it straightforward to find the right fit without guesswork.
What makes the Hive different from other HUUM heaters?
The Hive's defining feature is its beehive-shaped stone basket. That geometry is not purely aesthetic: it allows more stones to be packed in a structurally stable arrangement, which increases thermal mass and extends the time the heater can radiate heat after the element cycles off. Other HUUM lines use fewer stones and suit users who prefer a drier, faster-heating environment.
Can the HUUM Hive be controlled remotely?
HUUM heaters in this series are compatible with the HUUM UKU control system, which supports Wi-Fi connectivity and app-based scheduling. You can preheat the sauna remotely before you arrive, set timers, and monitor temperature without being physically present. Check the specific model listing to confirm which control units are included or sold separately.
How long do the stones last in a Hive heater?
Stone replacement frequency depends on usage patterns, water quality, and stone type. Most sauna professionals recommend inspecting the stone bed annually and replacing cracked or crumbled stones as needed. Because the Hive holds a large volume of stones, users typically replace a portion of the load at a time rather than the entire capacity at once, which keeps ongoing maintenance costs manageable.

Our sauna cabin sanctuary: quality & contentment!
For years I have enjoyed the health benefits of a regular sauna - choosing to install a glazed steam shower in our urban apartment more than a decade ago.
Frequent and extensive travels into Finland, exploring the Arctic north, confirmed our dedication to therapeutic steam (and ice plunges)!
Having relocated to a rural setting, it was time - at last - for a sauna cabin in the garden.
Thorough research confirmed the quality of the Leil range and the perfect option, for us, of the "round cube double" - an elegant, robust, thermowood construction with ample space as you enter through the separate changing room onwards into the beautifully benched and glazed interior.
The Leil "round cube double" is offered with a range of upgrades, sauna heaters and lights. We chose to keep it simple: just the glazed cabin, to suit our rural setting. However, we did opt for the larger 2.6m size, so that the benches are sufficient for those over 6' to enjoy a full horizontal stretch!
From start to finish, the Heracles Wellness team offered reliable expert advice and communication, as well as very helpful liaison during the delivery and construction phase. I wanted a quality product, but I also needed quality customer care for a complex delivery and technical installation.
The installation - organised by Heracles Wellness - was completed to schedule with real attention to detail: the team of carpenters had extensive experience with sauna construction, including the Leil range.
It was very clear what was included 'in the price' and what we needed to complete ourselves after installation: the electrical connection, interior wall and bench treatments must be completed before first use.
As we await those final stages - and the first sauna in the new cabin - the Leil "round cube double" has already become an exceptional sauna cabin sanctuary: quality and contentment!

We are thrilled with our sauna
We couldn’t be more pleased with our Camilla Traditional sauna kit. From start to finish Keith & Abdullah have been so helpful. The sauna has exceeded our expectations. The wood is beautiful quality. The Harvia heater heats the sauna really quickly. The installation was hassle free - we paid the additional fee for installation & Heracles arranged this for us. Communication has been excellent throughout. We shopped around before choosing Heracles. Heracles were cheaper than any of the other companies that we looked at & we consider the Camilla kit to be great value for such a high quality product. We are completely satisfied.

Amazing sauna accompanied by a brilliant service
I had done a lot of research before purchasing that sauna, looking for one that offer the right health benefits by having the right wood a sauna should have to conserve heat along with the best heater (Harvia) whilst still being value for money. The reviews gave me confidence after knowing the specifications aligned with what I wanted and I couldn’t be happier with having made the purchase. The service was brilliant, all my questions answered imminently , Abdullah was very patient and accommodating especially when getting the sauna installed and the electrics arranged by our own electrician. We paid extra for the sauna to be built and treated and the team were so professional and hard working doing an excellent job. Worth the money spent once again and would definitely recommend !

Amazing bit of kit alongside great customer service
Really pleased with the build quality of my Camilla sauna unit, it looks great particularly after applying necessary external and internal oil. Keith and team customer service and communication could not have been better, and Keith helped explain I could put heater on the left hand side of the sauna (as I enter) to help the electrician wire up to adjacent shed unit. Highly recommend.

So happy with my sauna!
After researching several different companies selling saunas, I was very happy to come across Heracles Wellness. I phoned them to ask some questions and they were very helpful in answering all my queries. I then decided to purchase the Insignia Hybrid Sauna.
A delivery date was set and the sauna was delivered as arranged with no problems.
With the help of a friend, we built the sauna and our electrician connected all the electrics up.
I have used the sauna a few times since it’s been up and running and I am very pleased with it as I have Parkinson’s and Rheumatoid Arthritis so hoping it helps alleviate pain and aching.
I would thoroughly recommend the company if you are looking for an excellent quality product and very good customer service.

My Luxurious Garden Escape!
I couldn’t be happier with my barrel outdoor sauna—it has completely transformed both my garden and my evening routine.
The craftsmanship is outstanding, with beautifully finished wood, a solid structure and an aesthetically pleasing design that makes the sauna look visually striking whilst having a practical layout too.
The curved barrel shape adds real character to my garden. It’s not just a sauna; it’s a true focal point that has elevated my entire outdoor space. It heats up quickly (in around 45 minutes) distributing warmth evenly inside.
In practical terms, my barrel sauna has proven to be a fantastic investment. Running costs have been very reasonable, working out at approximately £3 per session. Beyond that, the benefits to relaxation, wellbeing, and overall lifestyle have been outstanding. For example an unsightly cold sore completely disappeared after just two sauna sessions which otherwise would have taken a few weeks to heal.
A special thanks goes to Abdullan Yaqoob for his exceptional support from start to finish—nothing was ever too much trouble. He patiently answered all my many questions and even arranged for me to visit a previously installed sauna, which was incredibly helpful in making my decision.
Finally, I’d like to thank the installation team, who worked tirelessly—even in the snow—to have the sauna fully assembled in just seven hours. Their dedication and professionalism were truly impressive.
This sauna has genuinely elevated my home and wellbeing, and I'm delighted to recommend Hercales.

Wonderful product and service
Well what can I say. From my first enquiry through to installation and commissioning the experience of purchasing this High Quality product from Heracleswellness has been great!. When I spoke to Keith initially I was impressed with his friendly, Knowledgeable and professional manner he answered all my questions and sorted a rapid delivery of my selected Sauna kit. After watching the instructional build video i opted to have their team of experts do the build for me ( in hindsight a good choice and I consider it money well spent to optimise the build quality of the product.) Paval and his installation team arrived promptly and I found them to be a very professional and skillful bunch of lads. They worked Efficiently and left the work area on my patio clean and tidy. This is a 5 star product and a 5 star company in my opinion and I would happily recommend them to anybody in the market for this type of product
Thanks lads

Amazing in all areas
The Sauna looks incredible. The sales team were the most responsive people that I’ve bought something from in this country. The installation team were second to none - kind, friendly, keen to tell me about everything and ensure all was well with me.
I shopped around a lot and I also think Heracles are best value for money. If you are wondering weather or not to go for it then I irrefutably recommend you do! I’ve added a picture of the team in action. I laid the African railroad sleepers which is a perfect and good looking base.

5 stars
It arrived faster than I had expected. It came well packed on the back of a large lorry and put on my drive.
It took 2 of us 4 days to put together and the instructions were mostly ok. For the part we weren’t sure on, the flue, we were able to get help from the head office.
It is made from high quality materials and looks great. The timber has been pre-treated which saved me time.
Overall I am very pleased with everything.
