HUUM Drop 4.5 package: the wall heater, UKU control, and stones for a small sauna in one order
The HUUM Drop 4.5 package brings together a wall mounted electric heater, a control, and stones to heat a small sauna. The 4.5 kW heater heats rooms from 106 to 247 cubic feet. Made in Estonia from stainless steel, it is shaped like a drop of water and measures about 15 inches wide, 13 inches deep, and 23 inches tall. It weighs 24 pounds and holds 122 pounds of stones directly against the heating elements for soft heat and lasting steam.
The package includes the heater, a HUUM UKU control with its sensors and cables, and 132 pounds of rounded olivine sauna stones. The UKU lets you set the temperature from 104 to 230 degrees and schedule a start up to 48 hours ahead. On the page you choose the control: the standard UKU, or the Wi-Fi, Mirror, or Gold version that lets you start the sauna from your phone. A safety rail, an embedding flange, and a bucket and ladle set are optional. Heating a bigger room? See the HUUM Drop 6 heater package. The HUUM Drop 4.5 package ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What comes in this package?
It bundles the award-winning DROP 4.5 wall-mounted heater, an UKU control system with temperature and door sensors, and 132 pounds of rounded olivine sauna stones sized 2 to 4 inches. Everything arrives together, so the only remaining decision is which UKU control finish you prefer.
What size sauna is this designed for?
The package is engineered for sauna rooms from 106 to 247 cubic feet, which covers most compact home saunas. Calculate your room volume in cubic feet and compare it to that range; other sizes in the HUUM DROP series cover larger rooms.
Is the Wi-Fi control included in the base price?
The base price includes the UKU Local digital control in black, which handles on/off, time, and temperature. Wi-Fi versions in black or wood, plus the Mirror and Gold designs, are paid upgrades you can select in the Sauna Heater Controls options on this page.
Can I preheat the sauna before I get home?
Yes. Every UKU control supports a delayed start set up to 48 hours in advance, and if you choose a Wi-Fi model you can start or adjust the heater from anywhere through the HUUM mobile app on your phone, so the sauna is hot when you arrive.
What electrical hookup does the heater need?
The specification table lists 240V single-phase power at 18.8 amps, a 30-amp circuit breaker, and 10 AWG wire. Plan on a dedicated hard-wired circuit installed by a licensed electrician, following the installation manual and your local electrical code before the sauna goes into service.
How hot can I set it?
The UKU control offers a settable range of 104 to 230 degrees Fahrenheit, and its display shows both the set temperature and the current room temperature. A door sensor helps keep heat inside the room, and a child safety lock is built in for peace of mind.
What warranty applies?
The package components carry a limited 5-year warranty, excluding heating elements. The heater itself is SGS Listed, built from stainless steel with industrial-quality elements, and designed, engineered, and made in Estonia. Keep your documentation after setup in case you ever need warranty service.
