1. HENGJHU Steam Generators mainly use even power ratings
HENGJHU Steam Generators are mainly available in 6kW, 8kW, 10kW, 12kW, 14kW, and 16kW.
Higher power usually supports a larger steam room, but power is not the only selection factor.
Room conditions
Room volume, ceiling height, door sealing, and wall or floor conditions affect performance.
Power conditions
Voltage, phase, panel capacity, dedicated circuit, and wire size must match the unit.
Installation conditions
Unit location, service opening, steam pipe length, and pipe diameter should be checked.
2. 6kW, 8kW, and 10kW specifications
6kW, 8kW, and 10kW are often reviewed for residential or smaller steam rooms.
| Model | Power | Power Supply | Current | Wire Size | Suitable Space |
|---|---|---|---|---|---|
| HG-206 | 6kW | 220V single-phase | 28A | 8mm² | 3.5m³ |
| HG-208 | 8kW | 220V single-phase | 37A | 14mm² | 7m³ |
| HG-210 | 10kW | 220V single-phase | 46A | 14mm² | 8.25m³ |
| HG-306 | 6kW | 220V three-phase | 16A | 5.5mm² | 3.5m³ |
| HG-308 | 8kW | 220V three-phase | 21A | 5.5mm² | 7m³ |
| HG-310 | 10kW | 220V three-phase | 27A | 8mm² | 8.25m³ |
| HG-3306 | 6kW | 380V three-phase | 10A | 5.5mm² | 3.5m³ |
| HG-3308 | 8kW | 380V three-phase | 13A | 5.5mm² | 7m³ |
| HG-3310 | 10kW | 380V three-phase | 16A | 5.5mm² | 8.25m³ |
The same 6kW, 8kW, or 10kW power rating may have different current and wire size requirements depending on the power supply.
For example, 10kW is 46A with 14mm² wire under 220V single-phase, 27A with 8mm² wire under 220V three-phase, and 16A with 5.5mm² wire under 380V three-phase.
3. 12kW, 14kW, and 16kW high-power specifications
For larger steam rooms or higher use needs, 12kW and above may be reviewed.
| Model | Power | Power Supply | Current | Wire Size | Suitable Space |
|---|---|---|---|---|---|
| HG-312 | 12kW | 220V three-phase | 32A | 8mm² | 14m³ |
| HG-314 | 14kW | 220V three-phase | 37A | 8mm² | 16m³ |
| HG-316 | 16kW | 220V three-phase | 43A | 14mm² | 18m³ |
| HG-3312 | 12kW | 380V three-phase | 19A | 5.5mm² | 14m³ |
| HG-3314 | 14kW | 380V three-phase | 22A | 5.5mm² | 16m³ |
| HG-3316 | 16kW | 380V three-phase | 25A | 8mm² | 18m³ |
For 12kW and above, power conditions should be checked carefully. Current, wire size, breaker, panel capacity, and dedicated circuit all need review.
For commercial spaces, guesthouses, clubs, hotels, or high-use spaces, confirm whether the site has suitable three-phase power conditions.
4. Main unit dimensions should also be checked
Unit size is also important during planning.
The following dimensions are for HENGJHU Steam Generator series reference. Dimensions may vary by brand and model.
| Power | Main Unit Dimensions |
|---|---|
| 6kW, 8kW | L 45cm × W 15cm × H 33cm |
| 10kW | L 45cm × W 15cm × H 37cm |
| 12kW, 14kW, 16kW | L 45cm × W 25cm × H 37cm |
5. Suitable space is an initial reference, not the only decision factor
The suitable space in the specification table can be used as an initial reference.
6kW
About 3.5m³, usually reviewed for smaller steam rooms.
8kW and 10kW
8kW is about 7m³, and 10kW is about 8.25m³.
12kW and above
12kW is about 14m³, 14kW about 16m³, and 16kW about 18m³.
Actual planning should not rely only on volume. Ceiling height, door sealing, pipe length, steam outlet position, and use frequency can also affect the result.
6. Steam room height affects performance
Steam room height can affect the user experience.
In general planning, a steam room height within 220cm is easier to reach the desired feeling. If the room is too high, steam and warm air may gather near the top.
Power review
Higher rooms need a closer review of room volume and heat distribution.
Preheating time
A higher room may need longer preheating time.
User position
Check whether seated or standing users can feel the steam properly.
7. Voltage and phase affect current and wire size
The same power rating may have different current under different power supply conditions.
220V single-phase: 37A, 14mm² wire. 220V three-phase: 21A, 5.5mm² wire. 380V three-phase: 13A, 5.5mm² wire.
This means Steam Generator planning should confirm kW, voltage, phase, and power distribution together.
8. How to initially review 6kW, 8kW, and 10kW
For residential or smaller steam rooms, 6kW, 8kW, and 10kW are often reviewed first.
6kW
About 3.5m³, suitable as an initial direction for small steam rooms.
8kW
About 7m³, but room height and sealing still need review.
10kW
About 8.25m³, suitable as a reference for spaces near 8m³.
If the space is high, poorly sealed, has large door gaps, or has a long steam pipe, the selection may need to be reviewed again.
9. 12kW, 14kW, and 16kW require closer site review
12kW, 14kW, and 16kW are larger power configurations. They should not be selected by suitable space alone.
Power capacity
Three-phase power, panel capacity, wire size, and breaker should be confirmed.
Unit size
12kW, 14kW, and 16kW units are 25cm wide, so installation and service space matter.
Steam pipe diameter
Higher power may require more attention to pipe diameter, outlet sound, and pipe pressure.
10. Specifications still need to return to site conditions
Specifications help with initial selection, but they cannot replace site review.
Conclusion: understanding specifications helps selection go beyond kW
Steam Generator selection should not only ask how many kW the room needs.
A better review includes power rating, power supply, current, wire size, suitable room volume, unit size, and site installation conditions.
HENGJHU Steam Generators are mainly available in 6kW, 8kW, 10kW, 12kW, 14kW, and 16kW. Smaller to mid-range models can support residential and smaller spaces, while higher power models are for larger steam rooms or higher use needs.
Whatever power is selected, site conditions must be checked. Room size, power conditions, piping, unit size, service opening, and control panel location should work together.
