Who makes HUUM sauna heaters?
HUUM is an Estonian maker of electric heaters and wood stoves, all made in Estonia. Its Estonian design puts a large load of stone around the heat source for a traditional sauna heated with rocks. On HUUM electric sauna heaters, stones sit directly on the heating elements for soft heat and long-lasting steam. Every electric model runs from a HUUM UKU control outside the hot room.
Browse our complete heater collection to compare heating types. Our electric heater collection brings the electric options together. If you are choosing the room too, explore our sauna collection.
Wall heaters for compact rooms
The HUUM Drop has a rounded stainless steel bowl shaped like a drop of water. That shape won Europe's Red Dot design award. Its four sizes span 4.5 to 9 kW and cover rooms from 106 to 530 cubic feet. Open the Drop page to compare the room ranges, with 122 pounds of stones in every size.
The Cliff Mini wall column and Steel Mini wall heater are both rated 3.5 kW for rooms of 123 to 212 cubic feet. Cliff Mini has front ribs that lift off for stone stacking. Steel Mini has a plain stainless steel body only 6 inches deep.
Floor columns and round heaters
The slim Cliff column is 10.6 inches square, with lift-off front ribs, while the Steel floor column is 12.6 inches square and holds 331 pounds of stones. Both offer 6 to 10.5 kW sizes. Cliff covers 176 to 600 cubic feet, and Steel covers 212 to 600.
For a round shape, the Hive Mini range holds 330 pounds of stones and covers 176 to 706 cubic feet. Its sizes span 6 to 10.5 kW. The larger Hive floor heaters hold 552 pounds, the largest stone capacity of the range, with 12 to 18 kW sizes covering 424 to about 1240 cubic feet for large home and commercial rooms.
Wood burning stoves
A HUUM sauna stove lets you heat with wood. Every HUUM wood stove sits together on the wood burning stoves page. The Hive Wood stove range includes round stainless steel stoves and the smaller Hive Heat LS. The Hive Flow stoves put about three quarters of the fire's heat into the room and come in full size and Mini versions. LS versions let you add logs from the next room, while plain stoves load from inside the sauna. Stones and a chimney kit are added on the page, and our wood burning stove collection offers more options.
Controls, stones and packages
The HUUM sauna controller for every electric heater is the HUUM UKU, and you choose the standard, Wi-Fi, Mirror or Gold version on the page. There are no knobs on the electric heater itself. A HUUM Wi-Fi controller connects to the HUUM app for phone starts. The control sets temperatures from 104 to 230 degrees and schedules starts up to 48 hours ahead.
Choose a bare electric heater if you already have the control and stones, or add them on the page. Every electric package includes the control, sensors, cables and a full load of rounded olivine sauna stones. Only the full-size Hive needs the extension box, included in its package or added on the bare heater page. To choose a size, measure the sauna room and multiply its length, width and height in feet, then match those cubic feet to the individual heater's range.

Your questions answered
Is HUUM a good sauna heater?
HUUM is an Estonian maker with heaters made in Estonia. Electric models hold stones directly on the elements, from 122 pounds on Drop to 552 on Hive, for lasting steam. Each uses a HUUM UKU control, with Wi-Fi available for phone operation. Every listing carries the full manufacturer warranty.
Is HUUM or Harvia better?
We sell both Estonia-made HUUM and Finland-made Harvia heaters and stoves. HUUM pairs large stone loads with outside UKU controls and optional Wi-Fi. Several Harvia lines have built-in knobs, and its wood stove range is wider. The right choice depends on your room size, whether you want the controls on the heater or on your phone, and how much stone you want. Call us to talk it through.
How do I connect a HUUM sauna heater to Wi-Fi?
Wi-Fi comes from the control, not the heater. Choose UKU Wi-Fi, Mirror or Gold to connect your home network and HUUM app for phone starts and temperature settings. Standard UKU has no app. Follow the included manual for setup, and call us if you are unsure which control you have.
What size HUUM sauna heater do I need?
Multiply your room's length, width and height in feet to get cubic feet. Choose an individual heater whose listed room range covers that volume. Drop spans 106 to 530 cubic feet, while Hive reaches about 1240. Call us with your measurements to talk through the suitable lines and sizes.
Do HUUM heaters come with stones and a control?
Bare electric heaters need the control and boxes of stones added on the page. Packages include the heater, a HUUM UKU control with sensors and cables, and rounded olivine stones, plus the extension box on a Hive. Wood stoves come without stones or a chimney, both chosen on the page.
Where can I buy a HUUM sauna heater?
My Cozy Outdoors is an authorized HUUM dealer, with the full manufacturer warranty on every listing. Choose bare electric heaters or packages, or wood stoves with chimney kits added on the page. Call us and we will talk through your room and help you choose a HUUM sauna heater.
