The furnace is well-constructed to ensure an efficient burning and forceful flame. The flame tamer inside the stove is made of 5 mm stainless steel and can withstand the highest temperatures. Additionally, a heat exchanger can be mounted below the sauna stones to heat water while the wood is burning.

What is unique about the HUUM sauna heater?

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. 

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 roughly 10 degrees Fahrenheit every 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 warranty?

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