9. Choose a Right Steam Generator
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.
For comfort and leisure, to choose a correct steam generator is same important as to design the
steam room.
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.

10. How to build a steam bath room
Considerations in Designing a Steam Room
Generally, steam rooms are built with glass steels or acrylic materials and building materials. Easy installation
and good insulation characterize both the glass steels and acrylic materials. However, they are sufficiently poor
heat resistant, especially easily break and get damaged, while the cost is high. They are only suitable for
temporary entertainment centers. For the steam room built with building materials, the only need is to take some
measures to keep insulated. They are not only low in cost with excellent heat resistance and long service life,
but also can be made according to your needs with no building space limits. In such case, a safe, comfortable
and low cost steam bath room with long service life will be a real thing for you. Steam bath room in most of
counties and regions are made in the way.
Chief Instruction
The following messages are aimed to help the person who install steam generator or build steam bath room
only. Subject to the complexity of the building and the climate varies etc., this chief instruction is a
recommendation only.
Aims
When you plan to build a steam room, keep comfort and leisure as an aim in your mind. A room with correct
designs and structures should be installed comfortable seats and in which the temperature can be reached to30-
40℃in 15 to 20 minutes. If the space allows, it will be better to install seats with backrest or reclining benches,
these sorts of seats will make more comforts.
1. Avoid using decay building materials because the steam room is highly humid and wet.
2. All surfaces in steam bathroom must be protected with water proof materials, e.g. tiles.
3. Both seats and ceiling should have a certain slope, 15cm for each meter. Such kind of design reduces the
space of the steam bathroom.
4. Easy cleaning and drainage must be taken into consideration when designing the floor drainage. For the
consideration of safety, the floor must be slipping proof.
5. The heights of steam bathroom must be limited to 2.4m or below. Heights over 2.4m will cause a high or
adequate temperature around the ceiling, while the temperature around the floor is low.
6. The place for installation of the steam generator should satisfy the following conditions:
a) Have enough space for sufficient operation and for being in the situation that the steam generator needs
maintenance or fails to function and needs spare parts replacements.
b) The steam generator must not be frozen or moistened, and the temperature must not exceed 40°C (Never
install the generator inside the steam bathroom or outdoors.)
c) The steam pipe from steam bathroom to generator should be less than 6m. The steam pipe shall slope to
the steam bathroom and be higher than the position of the steam head, so that condensation shall drain into the
steam room and will not gather in the tube. Furthermore, the steam pipe should be well insulated.
d) To install the steam head complying with the instructions. The owner shall not touch the steam head.
e) The water drainage channel must be unblocked when you are installing the steam generator.
7. When you decide to use a certain materials for the inner walls of your steam bathroom, please take a contact
with the manufacturer to make sure that this material is of heat resistant and anti-humidity type.
8. Steam bathroom must be completely closed.
9. Situating a window at the ceiling is not recommended. If do so, the materials must be of waterproof type and
the window shall be tightly closed when in use.
10. Window and natural lights are not recommended either. If do so, must be sure the height and
size of the window in the steam bathroom will not affect keeping a comfortable temperature in a
long period of time.
