Choosing the right sauna heater

An electric sauna heater is a big part of your sauna interior, and partly it is important that it is adapted to the size of a sauna and at the same time it is an opportunity to put your own character in your sauna, with a large selection you can only choose the style of the sauna heater that suits you best.

A sauna heater is the heart of a sauna

Here you will find a variety of surface, color and shape to choose from everything from the classic sauna heater to the drip-shaped where the stone chest is completely visible. Obviously among the sauna heaters is good function and high quality with a goal to create the best sauna experience.

Choice of power requirement for electric heaters (kW)

It is the number of cubic meters (m 3 ) that is the basis for how many kW the sauna space requires.

Guidelines are 1kW = 1.3 m 3      (the number of cubic meters in your sauna / 1.3 = cubic meters the number to be adapted to the power of the unit)

Additional factors for calculating a sauna heater

The cubic meter volume in your sauna may need to be calculated as the power requirement is affected by, among other things, by:

- Surfaces in a sauna consisting of glass, concrete or tile increase the power demand and your sauna volume is calculated by 1.2.

Sauna volume x 1.2 = new calculated number of cubic meters / 1.3

If you have large areas of material that affect the power requirement, additional calculation can be made according to. below.

Per square meter (m 2 ) of tile, glass etc. that are in the sauna add 0.5 cubic meters (m 3 ) to the actual volume of the sauna.

Per square meter (m 2 ) of glass or uninsulated walls facing the outside of the house add 1 cubic meter (m 3 ) to the actual volume of the sauna.

Sauna insulation, is it insulated enough?

It is important to have good insulation of a sauna in walls and especially in the ceiling. If there is no insulation, the sauna volume should be calculated by 1.5

Sauna volume x 1.5 = new calculated number of cubic meters / 1.3

(The above calculations are for a sauna in private use)

About the sauna heating

Don't choose too high power on your electric heater. An oversized unit can cause it to malfunction. The function of the unit is that stones are laid for heating on the heat source (coils of the unit). A good heating of the sauna is based on the fact that the unit will work for a long time to allow the stone warehouse to heat up. If you choose too high an effect for your space, you get a dry and hot sauna when the unit works for a short time to heat the stones. When "bathing" water is poured with a scoop over the stones, the stones are really hot evaporate the water and the humidity in the sauna increases. If you choose a sauna heater with too high power, your sauna heats up quickly, when the temperature is reached, the heater is switched off and then works for shorter periods. This can lead to the stone warehouse becoming cold and during bathing the water does not evaporate effectively, you get a hot and dry sauna.

The best sauna bath

Only you yourself know how it should be in your sauna to get the best enjoyment, there are no given rules. Most too dry saunas, most people do not think is a pleasant experience, the interest goes towards the more humid sauna.

Normal temperatures to baste in are at 70-90 degrees C.
