HUUM Sauna Heater FAQ's

Sauna Heater

The typical lead time for HUUM sauna heaters is between 7 to 9 days, depending on your location.

HUUM sauna heaters stand out with their sleek, minimalist, and rounded design, making them among the most stylish options available. They feature a notably high stone capacity, which ensures a gentle and enduring steam experience, closely resembling that of traditional saunas. The design minimizes the use of metal, so the warmth primarily radiates from the stones rather than from heated metal surfaces. This results in a higher concentration of negative ions in the air, which are believed to offer various health benefits. Additionally, pairing the heater with a UKU Wi-Fi or GSM controller allows you to easily manage your sauna’s temperature from your mobile device.

HUUM offers a range of heaters designed to suit various sauna room sizes, from compact spaces to larger rooms. Their models are suitable for saunas with volumes ranging from 106 to 1,236 cubic feet.

Choosing the right heater output depends on the size of your sauna room and its insulation.

As a general guideline, you need 1 kW of power for every 35 cubic feet (1 m³) of sauna room volume.

If the heater is underpowered, it may heat the sauna too slowly, produce insufficient steam, and wear out faster. On the other hand, a slightly more powerful heater won’t cause issues if it has a thermostat and is used correctly.

Another crucial factor is the insulation of your sauna room. If you have any uninsulated brick, tile, glass, or log walls, you should add an additional 53 cubic feet (1.5 m³) to your sauna room size calculation for every square meter of such wall.

To calculate the appropriate heater size, multiply the height, width, and length of your sauna in feet. Then, add 53 cubic feet for each square meter of uninsulated surface. This will give you the total volume of your sauna in cubic feet, which you can use to determine the suitable heater output. If your calculation falls between two heater sizes, it’s generally better to choose the larger one.

If the heater is correctly sized, it heats up at a rate of about 50°F every 8 minutes, reaching 176°F in roughly an hour.

HUUM heaters are crafted primarily from high-quality stainless steel, with careful attention to detail and craftsmanship. The production involves handcrafting components, ensuring durability and a sleek finish. The design process also emphasizes sustainability, utilizing materials efficiently to minimize waste.

All HUUM heaters are produced in Estonia.

All HUUM sauna heaters come with a 5-year guarantee.

The HUUM Heater includes the heater, along with adjustable legs for HIVE models or a wall mount for DROP models. However, stones, controller, are sold separately unless you choose one of our All-in-One HUUM heater packages.

HUUM Heaters are hardwired, requiring installation by a licensed electrician.

HUUM Controllers

The key difference lies in how you control your sauna. With the UKU Local, you can only operate your sauna from the wall-mounted control panel. The UKU Wi-Fi controller, however, allows you to control your sauna remotely through the HUUM mobile app, provided you have a Wi-Fi connection.

No, HUUM heaters require a controller with temperature control as they do not have an on/off button.

The control panel should be installed outside the sauna at eye level near the door or according to the manufacturer’s guidelines. The main module should be placed in a dry, accessible location—preferably not inside the sauna. If using a UKU Wi-Fi controller, ensure the main module can connect to the internet from its location.
