5. Choose a Right Steam Generator
For comfort and leisure, to choose a correct steam generator is same important as to design the
steam room.
A. Considerations in Choosing a Model
1. Water Quality
More impurities or minerals in water, should the steam generator be rinsed more often. Automatic
cleaning should be taken into consideration so as to save manual labors if the water quality is
poor.
2. Heat Control
A model, which has a temperature control, will be the best choice if steam generator is used
frequently, or if you want to keep a comfortable temperature constantly in steam room for a
longer time.
3. Digital Indicate
Steam bather can choose a simple operation way or a complex feedback control to set the
temperature, steam bathing time and procedures.
4. Lamps
lamps in sauna-bath room must be of safe low voltage type
B. Considerations in Choosing Power Ratio and Voltage of the Steam Generator
1. The volumes and the surface of the steam bath room.
2. The quality and heat transmitting of the materials of all surfaces in sauna bath room.
3. The height of the ceiling and the benches.
4. If the outer wall of the steam room can be able to withstand the great temperature changes.
5. Voltage of electric source and phase electricity(220V, 380V, a single phase electricity or three
phases electricity). Lower voltage causes less steam.
6.When installing the steam generator, we recommend using a larger size cable than normally
used.
C. Announcement
The above messages are recommendations only. These recommendations may not be suitable
as the conditions of installation and areas are different. The effect of the steam generator can not
get guaranteed if one chooses the building materials and builds rooms only depending on the
above information.
D. Preparations
1.To calculate the volumes of a closed steam bathroom: length X width X height=volume. If there
are outshoot surfaces need heating, their volumes shall be added: length X width X
height=volume
2.The above calculations should take the following factors into consideration:
a). Tiles, polypropylene or fiber glass steel
b). The mortar bed for tiles or concrete foundation
c). Cast-iron pipe
d). If temperature declining is possible, to add10% to100% to each glass or glass wall and to the
outer wall
e). Natural stones e.g. marble.
Totals=1 + 2 a+2 b+2c+2d+2e
3. Compare the size chart of first page and choose models
according to the above calculating results.
