Thetemperatureisadjustedbymeansofthecontroller(seepage15).Theactualheatingtimedepends
onthedimensions,structureandthermalinsulationofthesauna.Thetemperatureinthesaunaroom
canbemaintainedatthedesiredlevelwiththethermostat.Ifthetemperatureofthesaunaroom

Anexcessiveheatingtimeconsumesenergyanddoesnotimprovethesteamingproperties.Thebest
steamisachievedbykeepingthesauna’sheatingtimerelativelyshort,atabout30–60min.,according
tothesizeofthesaunaandtheheater’spower.Thesizeofthesauna,theglassdoor,windows,or

Thesaunaanditsceiling,inparticular,shouldhavegoodthermalinsulation,asheattendstoescape
throughtheceiling.Duetothemoisture,werecommendthatyouusealuminiumpaper.Thesizeofthe

thepowerneedfortheregularsaunastructure(glasswool–foil–wood),thefollowingshouldbetaken
intoconsideration.Ifthesaunahasanyuninsulatedwood,tileorconcretesurfacesorthewallsare

also1.2m3persquaremetre.Inborderlinecases,youshouldchooseaheaterwithhigherpower.
Thesaunaneedsecientventilationforagoodoxygenlevelandasucientamountoffreshair.Theair
inthesaunaneedstochangeatleast6timesperhour.Forasaunawithanelectricheater,mechanical
ventilationisthemostconvenientventilationmethod.Thesupplyairshouldbeprovidedthroughan
inletlocated500mm,ataminimum,abovetheheater,eitheronthewallorintheceiling.Theexhaust
