Smart Best Recommend
4 Reasons to Buy
Full scene voltage adaptation
110V/220V dual voltage compatibility
Automatic recognition of North American/Asian standard voltage, no need for renovation for overseas rentals or old circuits
The measured switching voltage response time is less than 3 seconds, which is 70% more applicable than traditional single voltage models
Intelligent power regulation
3000W mode compatible with 15A ordinary socket (such as small water usage in the kitchen)
5500W mode requires a 25A dedicated line (shower scenario), with a heating speed 83% faster than 3000W

Breakthrough in Instant Heating Technology
3-second rapid heating system
Using T4 superconducting heating element, the thermal efficiency reaches 94.3% (industry average only 85%)
Constant temperature control error ± 1 ℃, avoiding the problem of sudden water temperature changes in traditional models
Space optimization design
Wall mounted installation with a thickness of only 18cm saves 60% space compared to water storage type
IPX4 waterproof rating can be directly installed in the shower area

Safety and Energy Efficiency
Eight fold protection system
Includes leakage protection, dry burn protection, and overvoltage power-off, certified by UL/CE
Design of water and electricity separation structure to eliminate the risk of leakage in traditional heating tubes

Energy consumption optimization
On demand heating saves 2.3 degrees per day compared to water storage (measured data)
Timed shutdown can be set to avoid no-load power consumption of 37
Note: In the 5500W mode, it is necessary to ensure that the household wire is ≥ 4mm ². It is recommended to conduct circuit testing before installation

Performance Data
Heating performance
Dual voltage design (110V/220V) compatible with mainstream global power grids, with adjustable power levels of 3000W/5500W. Tested hot water output in 3 seconds in 5500W mode at 220V
Infinite temperature control technology supports precise temperature control of 30-60 ℃, with a temperature difference of ± 1 ℃
Security protection
Triple overheat protection: temperature sensor+fuse+automatic power-off, shell temperature resistance up to 120 ℃
IPX4 waterproof rating, bathroom installation should be kept at least 0.5 meters away from the shower area
Energy efficiency performance
Heating 1 liter of water in 5500W mode consumes approximately 0.018 kWh, which is 15% more energy-efficient than storage water
Continuous operation for 1 hour at 220V voltage, shell temperature ≤ 65 ℃

Use Tips
Installation points
Wall mounted installation requires the use of expansion bolts for fixation, with a load-bearing wall thickness of ≥ 10cm
The power cord must be connected to a 16A dedicated socket with leakage protection
Operation process
Switching voltage: Long press the power button for 5 seconds until the indicator light flashes, and select the voltage mode through the APP
Power regulation: rotary knob design, clockwise rotation increases power (3000W → 5500W)
Intelligent functions
Support preset heating periods on the app (such as automatic activation during peak water usage periods in the morning and evening)
Memory function: Automatically restore the last set temperature after power failure

Safety Tips
Use safety
It is prohibited to connect multiple devices in series. The 5500W mode requires the use of 4 square millimeter copper wire separately
Long term disuse requires closing the inlet valve and draining the remaining water to prevent freezing and cracking
Maintenance and upkeep
Clean the inlet filter screen monthly (removable by counterclockwise rotation)
The heating element needs to be cleaned every 2 years (soaked in citric acid solution for 15 minutes)
Fault handling
E1 code: Abnormal inlet water temperature sensor, check the connecting wire
E4 code: Overheating protection triggered, waiting for 10 minutes for automatic reset
