Selecting the steam generator output for the steam room

You can estimate the power requirement using the formula below.
Volume (m3) x K1 x K2 = Power requirement (kW)

Forced ventilation K1 = 0.75
No ventilation K1 = 0.52
Acrylic wall K2 = 1.00
Light wall: board + tile K2 = 1.25
Heavy wall: stone, concrete + tile K2 = 1.50
Very heavy wall: stone, concrete + tile K2 = 2.00

In heavy built steam rooms, it is recommended to use e.g. electric heating cable for warming the seats, walls and floors.
