To get instant hot water, electric kettle is very good for household work.
1. Select the design first. But it depends on your personal preference. However, make sure that it is not too heavy.
2. Then select the size of the kettle. 1-2 liter kettle is enough for household works. But for office or party a little bigger should be chosen.
3. Test the efficiency of the kettle as if it boils a small amount of water then it should use less electricity.
4. Electric kettle must have auto shut-off feature. When the water boiling is finished, it should stop automatically.
5. Plastic kettles are a little cheaper but stainless steel kettles are more durable.
