What a HUUM Package Actually Is (and Why It Exists)
Here's the thing most people don't catch until the box shows up: a HUUM electric heater on its own doesn't run. HUUM sells the heater, the controller, and the stones as three separate products on purpose, so designers can mix finishes. But every electric HUUM requires a UKU controller to function. Buy the heater alone and you've got a beautiful steel sculpture that won't turn on.
A package solves that. Each bundle in this collection ships the heater, the controller it needs, and the right quantity of stones to fill the basket — matched, compatible, and configured the way HUUM's own technical team would spec a residential install. You skip the "wait, which controller do I need?" problem entirely, and you save a few hundred dollars versus piecing the same set together from individual SKUs. One order, one delivery, everything talks to everything.
This page is the full HUUM package lineup — both fuel types. If you already know you want electric, the electric package collection narrows it down. If you're on an off-grid site or you want the fire-tending ritual, the wood-burning packages bundle the stove with the correct chimney kit and stones instead of a controller. Still deciding?

Electric or Wood-Burning: The First Fork
The biggest decision here isn't the model — it's the fuel. They're genuinely different products with different package contents.
Electric packages (DROP, CLIFF, HIVE, HIVE Mini, STEEL) are what most home buyers land on. Set a temperature, set a timer, walk away — or with a WiFi UKU, preheat from your phone on the drive home. The package includes the heater, a UKU controller, and stones. The trade-off is the electrical: every electric HUUM is a hardwired 240V unit that needs a licensed electrician, not a wall plug.
Wood-burning packages (HIVE Wood and the more efficient HIVE Flow series) are fire and stone — no controller, no electrician, no breaker. The package bundles the stove, the chimney kit you actually need for safe venting, and a full set of stones. These suit off-grid cabins, anyone who wants the crackle and ritual of a real fire, or sites where running a heavy 240V circuit isn't practical. The trade-off: wood heaters take longer to come up to temperature (figure 60 to 90 minutes given the heavy stone mass) and you're tending a fire rather than tapping an app.
The HUUM Models, Explained
HUUM's whole design philosophy is oversized stone capacity — more rock means softer, longer-lasting löyly when you ladle water across it. The silhouette and stone load differ across the lineup.
DROP (4.5kW, 6kW, 7.5kW, 9kW, electric) is the wall-mounted teardrop. The most compact footprint and the easiest install, covering rooms roughly 177–530 cu ft. The 6kW and 7.5kW are the volume sellers for 2–4 person indoor saunas; the 9kW handles larger outdoor cabins and high ceilings.
CLIFF (6kW, 9kW, 10.5kW, electric) is the angular freestanding pillar with a heavier stone load than the DROP — noticeably softer steam and faster recovery after you throw water. It's the move for 5–6 person cabins. The CLIFF Mini (3.5kW) is the smallest HUUM made, sized for sub-212 cu ft closets and one-person builds where most brands' small heaters skimp on stones.
HIVE (12kW, 15kW, 18kW, electric) is the cylindrical cage flagship, holding up to 595 lbs of olivine — the most thermal mass in the residential category. Designed for 424–1,236 cu ft rooms: large outdoor cabins, multi-tier builds, oversized custom installs. HIVE Mini (6kW, 9kW, 10.5kW) shrinks that look to a 330-lb stone load for mid-size rooms up to ~706 cu ft.
STEEL (6kW, 9kW, 10.5kW, plus a 3.5kW STEEL Mini, electric) is the polished mirror-finish cage that disappears into modern bathroom and bench builds. Same sizing as the HIVE Mini in a brighter stainless skin.
HIVE Wood and HIVE Flow (wood-burning) are the fire options. The standard HIVE Wood 17kW is a powerhouse for larger saunas; the HIVE Wood 13kW covers 212–459 cu ft. The HIVE Flow series (8.5kW and 9.8kW) is the more compact, efficient design, and the LS variants add a firebox extension so you can load and light from outside the room. Shopping bare stoves instead? The HUUM wood stove collection has them à la carte.
Which Controller Comes in the Electric Package
Every electric package includes a UKU controller — you're choosing the interface, not whether you get one. There are four flavors:
-
UKU Local — the wired wall panel without WiFi. Handles temperature, timer, and scheduling at the wall in black, white, or wood. The simplest, most affordable option.
-
UKU WiFi — adds the HUUM app, so you can preheat from the car, set recurring schedules, and see live heater status from your phone. The UKU WiFi controller is the one most buyers upgrade to.
-
UKU WiFi Glass and UKU WiFi Mirror — same WiFi functionality, but a minimalist glass or mirrored front panel that blends into a finished bathroom wall instead of announcing itself as a controller.
This is exactly the question packages solve. HUUM sells these controllers separately and they aren't cheap on their own, so a buyer piecing it together has to figure out which one pairs with their heater, then order it, then order stones, then hope the math is right. The package does that work and hands you a matched set. HUUM's app, for what it's worth, is the most polished in the category — name multiple saunas, lock the panel from kids, set per-day schedules.
Sizing the Package to Your Room
The math is simpler than retailers make it sound. Measure your sauna's interior in feet — length × width × height — to get cubic feet, then match that against the kW range listed on each package page. The standard guideline is about 1kW per 45–50 cubic feet. HUUM's heavy stone load actually lets you size down one step from a lower-mass heater and still hit traditional 190–210°F temperatures, because all that rock stores and releases heat.
Rough reference using packages here: a sub-212 cu ft one-person closet wants the CLIFF Mini or STEEL Mini 3.5kW; a 2–3 person indoor room wants a DROP 6kW or 7.5kW; a 4-person outdoor cube fits the DROP 9kW or HIVE Mini 9kW; a 5–6 person cabin calls for the CLIFF 9kW or 10.5kW; and 6+ people or commercial use moves to the HIVE 12kW–18kW. For outdoor cabins in cold climates, add 10–15% to account for thicker walls and longer preheat. When you're between sizes, go up — an undersized heater stalls below temperature and never recovers after you pour water.
Electrical Requirements (Electric Packages Only)
All HUUM residential electric packages run on 240V single-phase, hardwired on a dedicated breaker — no plug, no sharing a circuit. As a general reference: a 4.5kW DROP pulls roughly 19 amps and wants a 25A breaker; a 6kW needs about 25A on a 30A circuit; 7.5kW needs about 31A on 40A; 9kW needs about 38A on 40A; and the 10.5kW CLIFF and STEEL want a dedicated 50A breaker. The larger HIVE units (12kW, 15kW, 18kW) draw serious amperage and may require a panel upgrade or three-phase service, so confirm what your panel can supply before ordering. HIVE configurations above 12kW also use the UKU Extension Box contactor, which ships with those packages.
These figures are general reference only and do not substitute for a professional assessment. Electrical requirements vary by local code and jurisdiction — every HUUM electric install must be wired by a licensed electrician who verifies the breaker size, wire gauge, and panel capacity for your specific home. Our sauna electrical requirements walkthrough covers the full amperage table and what to ask before the crate lands in your driveway. Wood-burning packages skip all of this — no circuit, no electrician, just a safe chimney run per the stove's spec.
Package vs. Piecing It Together
If you want a standard configuration — a DROP 6kW with UKU Local, or a CLIFF 9kW with UKU WiFi — the package is the clear move. Single shipment, guaranteed compatibility, and a few hundred dollars saved versus individual SKUs. À la carte only makes sense for a non-standard combo (say, a DROP heater with the Mirror controller, or a custom stone upgrade). In that case, build it from the bare heater in the HUUM electric heater lineup, the controller you want, and the right box quantity of HUUM stones to fill your basket.
Want the broader cross-brand view before you commit? The full heater package hub compares HUUM against the other brands we carry, and the Harvia electric packages are the main alternative if you want a longer field track record at a lower entry price. If you'd rather round out a HUUM build with safety rails, embedding flanges, or a DROP drip tray, those live under heater accessories.
One more thing worth knowing: HUUM had element-failure reports in years past, which is why some forum threads still scare people off. That hardware was updated, and feedback since has been consistently positive. Warranty coverage is valid only through authorized dealers — grey-market imports from marketplace resellers often aren't covered even when the SKU looks identical. If you're not sure which bundle fits your room, call us. Matching a heater to a space is exactly the kind of thing we'd rather get right on the phone than have you guess at.
