FAQs

What is unique about the HUUM sauna heaters?

The sleek and rounded shape of HUUM sauna heaters makes them some of the most stunning sauna heaters on the market. They provide gentle and long-lasting steam akin to traditional saunas due to their unusually high stone capacity. Because there isn't much metal in the heaters, the heat comes from the stones rather than the heated metal. Because of this, the air is filled with more negative ions, which are believed to be helpful to one's health. You can easily heat your sauna from your phone by pairing the heater with a UKU Wi-Fi or GSM controller.

How do I choose a heater with the right output?

The output of the sauna heater should be determined by the size and insulation of the sauna room.
To heat 1 m³ of the sauna room, you'll require 1 kW of power on average.
If the heater is too tiny, the sauna will heat up too slowly, not enough steam will be produced, and it will burn out more quickly. If a heater has a thermostat and is used correctly, a heater that is somewhat too strong will not cause problems.

The sauna room's insulation is the second key factor to consider. If the sauna room has any uninsulated brick, tile, glass, or logs walls, the sauna room size should be increased by 1.5 m³ for each m2 of uninsulated brick, tile, glass, or wood wall.

To determine the volume of your sauna room, utilize our sauna calculator. Multiply the height by the breadth and the length in meters to get a rough estimate. Then add the sum of uninsulated brick, tile, glass, or wood surfaces (m2) to the preceding result by multiplying it by 1.5. Because of this, you will be able to calculate the size of your sauna room in m³, from which you may choose the appropriate heater output. We recommend choosing the larger output value if the result lies between two alternative output values.

How long does it take to heat the sauna?

If the heater is large enough, it will heat up to 80 degrees Fahrenheit in an hour at a rate of roughly 10 degrees Fahrenheit per 8 minutes.

What kind of stones can be used with HUUM heaters?

We recommend utilizing sauna stove stones that are rounded and natural. We have light grey, rounded olivine diabase stones with a high heat capacity in our inventory. Because decorative stones are readily broken, they should not be used in the heater.

What material are HUUM heaters made of?

Stainless steel is used to make HUUM heaters. 

Where are the heaters produced?

All HUUM products are made in Estonia.

How long is the guarantee?

There is a 5-year warranty on all HUUM sauna heaters.

What is included in the set?

The heater and adjustable legs (HIVE) or wall mount are included in the kit (DROP). Stones, controller, and power cable are not included in the set.

Who can install the heater?

The cabling and connection of the heater to the power source should be done by a licensed electrician.

How can I replace my existing sauna heater with a HUUM heater?

Is your existing sauna heater a mechanical heater or does it have a controller?

Simply replace the sauna heater if it has a temperature control option on the controller. Install the heater with the help of a certified electrician and according to the product installation manual.

Do you have a sauna heater that isn't controlled by a controller (the heater's switch is on)? You'll need a controller with a temperature control feature, as well as some connections to connect it to. Using the help of a competent electrician, follow the directions in the product installation manuals. It's possible that you'll need to tear down some walls and run new wires.

Which kind of wiring will I need?

Installation instructions for cables can be found in our product installation manuals. A licensed electrician is required to install the cables.
