HUUM Hive Flow Mini LS Wood Burning Sauna Stove
Description
HUUM Hive Flow Mini LS Wood Burning Sauna Stove
Designed for smaller sauna spaces, the HUUM HIVE Flow Mini LS brings exceptional performance with its smart firebox extension. Its advanced construction makes sure that the majority of the firewood’s heat stays inside the room instead of disappearing up the chimney. With its impressive efficiency and eco-friendly operation, it’s an ideal choice for sauna rooms ranging from 212 to 494 cubic feet.
The Firebox Extension Advantage
What sets the HUUM Hive Flow Mini LS apart from standard wood burning sauna stoves is its firebox extension feature. This clever design element allows you to load wood from outside the sauna room, which is a game-changer for convenience and comfort. You can tend to the fire without disrupting your sauna session or letting precious heat escape through an open door.
The firebox extension means you can place the loading door in an adjacent room, hallway, or even outdoors. This keeps smoke, bark debris, and wood dust out of your pristine sauna space. It's a practical solution that serious sauna enthusiasts appreciate, especially during longer sessions when you need to add more Hive wood to maintain optimal temperatures.
Unmatched Heat Efficiency
This wood burning sauna heater captures an impressive 75% of the heat generated by burning wood. Most traditional wood fired sauna stoves lose significant warmth up the chimney, but the Hive Flow Mini LS redirects that energy where it belongs — into your sauna room. This exceptional efficiency means you'll burn less wood while enjoying better, more consistent heat.
The 8.5 kW output of this wood sauna heater is precisely calibrated for sauna rooms from 212 to 494 cubic feet. Whether you're heating a cozy home sauna or a small commercial space, this HUUM sauna heater delivers reliable performance without waste.
Over time, the fuel savings add up significantly, making it both an economically and environmentally smart choice.
Generous Stone Capacity for Superior Heat
The Hive Flow Mini LS holds 231 lbs (105 kg) of stones — a remarkable capacity that directly impacts your sauna experience. These sauna stones act as a thermal battery, absorbing heat from the fire and releasing it gradually. When you ladle water over the heated stones, they create the characteristic steam and humidity that defines authentic sauna culture.
More stone mass means better temperature stability. You won't experience dramatic heat drops when adding water or when someone opens the door.
The substantial weight of stones maintains consistent warmth throughout your session, creating a more enjoyable and therapeutic environment. This generous capacity is one reason why experienced sauna users choose HUUM products.
Watch the Flames Dance
There's something primal and deeply relaxing about watching fire. The HUUM Hive Flow Mini LS was designed so you can enjoy the mesmerizing flames dancing on the fire chamber during your sauna sessions.
The transparent chamber transforms your sauna into more than just a hot room — it becomes a space for meditation and connection with elemental forces.
This visual element enhances the entire experience. As you relax on the benches, the flickering flames provide a natural focal point that helps quiet the mind. Combined with the warmth, the crackling of burning wood, and the steam from heated stones, the fire view creates a multi-sensory sanctuary that electric heaters simply cannot replicate.
Flexible Installation with Dual Chimney Connections
The HUUM Hive Flow was designed with two separate chimney connections, giving you installation flexibility that most wood burning sauna stoves lack. Depending on your building's layout and your sauna room configuration, you can choose which chimney connection works best. This feature is particularly valuable when retrofitting existing spaces or dealing with architectural constraints.
The dual connection option, combined with the firebox extension, means you have exceptional control over your installation. You can optimize both the stove placement and the wood loading location independently, creating a setup that truly works for your specific space and usage patterns.
Built for Lasting Performance
HUUM has earned its reputation by creating wood burning sauna heaters that combine traditional craftsmanship with modern engineering. The Hive Flow Mini LS reflects this philosophy in every detail, from its efficient combustion system to its durable construction. This wood fired sauna stove is built to provide years of reliable service.
The fire chamber is constructed from heat-resistant materials designed to withstand the intense temperatures generated during operation. The thoughtful engineering ensures even heat distribution while minimizing wear on critical components. When you invest in a HUUM sauna heater, you're choosing equipment that's built to last.
The Perfect Choice for Convenient Sauna Heating
This model with a firebox extension represents the ideal solution for those who want the authentic experience of a wood burning sauna stove without the inconvenience of loading wood from inside the sauna room.
With high heat retention, a massive 231-pound stone load, a striking view of the flames, and versatile setup possibilities, this heater offers long-lasting quality and standout performance.
