Stones

We highly recommend using rounded stones in HUUM heaters to complement the design and have a milder steam. In our selection we have rounded olivine diabase stones in two different size ranges: 5-10 cm and 10-15 cm. The stones are durable and have a high heat capacity. You can also use other types of stones in HUUM heaters, except decorative stones because they can break easily.

Choose your stones wisely

Throwing water on the stones is how you regulate heat and steam in the sauna. The shape, size and composition of the stones and the way they are arranged make all the difference. We recommend rounded stones because they provide a milder steam. Thanks to the rounded shape the water can reach inner layers of stones and evaporate gradually instead of evaporating all at once from the top layer. Since they are very visible in HUUM heaters, you need both smaller and bigger stones to avoid big noticeable gaps. We also suggest laying smaller stones and more close together on the top to accumulate the heat better.

What is best for your sauna?

The volume and structures of the sauna affect the selection of heater power. The power requirement increases if there are window surfaces or heat-storing surfaces such as brick, concrete or massive logs in the sauna.
Dimensions of sauna (m)
Multiply the height by the width and the length in meters.
Do you have a glass door?
Glass door adds + 1,5 m² to your sauna volume.
Non-insulated walls (m )2
In case there are any uninsulated brick, tile, glass or log walls in the sauna room, an additional volume of 1.5 m³ for each m² of such wall should be added to the sauna room size calculation.
