HUUM Drop Electric Sauna Heater
The HUUM Drop is one of the most recognisable sauna heaters in the world: a steel cage shaped like a falling water drop, filled with stones. It's wall-mounted, compact and award-winning, and because the stones surround the elements, you get soft, rich steam that feels much closer to a wood-fired sauna than a typical electric heater.
Choose your model
| Drop 4.5 | 4.5 kW, saunas of 3 to 7 m³ |
| Drop 6 | 6 kW, saunas of 5 to 9 m³ |
| Drop 9 | 8.5 kW, saunas of 8 to 13 m³ |
Choose your package
| Heater only - Control Panel Required | The Drop has no controls of its own, so it needs a separate control panel. Choose this if you already have a HUUM UKU |
| Heater + HUUM UKU Local Control Panel | Heater and the UKU Local Classic control panel (no WiFi), so all that's left to add is the stones |
| Heater + HUUM UKU WiFi Control Panel | Heater and the UKU WiFi Classic control panel, so you can also start the sauna from the HUUM app |
Control Panel Required for Heater Only (Sold Separately)
HUUM's manual is clear that the Drop needs a control system to run. The easiest way is one of the heater + control panel options above. Each includes:
- HUUM UKU Local Classic or UKU WiFi Classic control panel: control panel, main module, temperature (safety) sensor, bench sensor, door sensor kit and heat-resistant sensor cable. Run the sauna from the wall, or with WiFi from the HUUM app too
Recommended stones (not included)
The Drop takes about 55 kg of natural sauna stones. HUUM recommends rounded stones, which suit the Drop's look.
- Our pick: Harvia Rounded Olivine Diabase Sauna Heater Stones, 10–15 cm (20 kg box), 3 boxes
- Alternative: Round Traditional Sauna Heater Stones, 5–7 cm (16 kg box), 4 boxes
Can I put it straight into my sauna?
Yes. It mounts on the wall with the bracket supplied, and once it's wired in and loaded with stones you're ready to go. You'll need:
- A control panel (included with the heater + control panel option)
- Stones: as above
- A registered electrician to wire the heater and control panel. HUUM specifies 400 V three-phase (3 x 10 A for the 4.5 and 6, 3 x 16 A for the 9). Single-phase 230 V is possible when wired through the UKU, so ask your electrician which suits your home
- A wall that can take the weight: about 65 kg with stones, fixed into solid framing
- Safety distances from the manual (100–150 mm to side walls depending on model, room height ideally 2.0–2.3 m)
Why you'll love it
- Iconic design that turns the heater into a feature
- Soft, wood-fire-like steam from 55 kg of stones
- Wall-mounted to save floor space in smaller saunas
- App control with the UKU WiFi: heat the sauna on your way home
