Buying Guide (Universal for electric kettles/coffee makers/mini water heaters/water boilers):

1. Consider the intended use: boiling water or dry-boiling?

For boiling water, coffee makers, and water heaters → Choose a liquid heating model. High power density, fast boiling, and good sealing.

For cap drying, ovens, and air heating → Choose a dry-boiling model. Lower power rating and high-temperature resistant materials are necessary to prevent burnout.

2. Consider the voltage (most crucial):

Domestic household: 220V 50Hz
Export to North America: 110V / 120V
Industrial equipment: 380V
Choosing the wrong voltage will render the appliance unusable.

3. Choose the power rating based on capacity:

1.0~1.5L kettle: 1500W

1.5~2.0L kettle: 1800W / 2000W

6~10L mini water heater: 1500W / 2000W
Too high a power rating will cause it to burn out easily; too low a power rating will boil water slowly.

4. Check the material: Must be food-grade.

Drinking water, coffee, hot water: Food-grade SUS304 stainless steel.
Areas with poor water quality or prone to scaling: 316L stainless steel is optional.
Do not use industrial pipes; they have an odor and are unsafe.

5. Check the pipe diameter:
Small kettles, coffee makers: Φ8mm.
Large kettles, small water heaters: Φ10mm. The pipe diameter must match the installation space.

6. Check the flange size (whether it will fit):

Measure the size of the mounting hole at the bottom of your equipment.
Commonly used: Φ80mm / Φ90mm / 100mm. A flange that is too large will not fit; a flange that is too small will leak.

7. Check the spiral coil size:
The outer diameter of the spiral coil must be smaller than the inner diameter of the kettle bottom.
Generally: Φ60~Φ90mm. Too large and it won't fit; too small and heating will be slow.

8. Must meet safety requirements:
Must have anti-dry-burning and thermostat.
Must be completely submerged in water for use.
The sealing gasket must be made of high-temperature resistant silicone.
