Electric water heaters are now concentrated in three brands: AO, Ariston, and Haier. There are also other brands, but according to your own money, it is recommended that you choose among the three brands. The quality is relatively reliable. Kitchen treasures are named after electric water heaters that are mainly placed in the kitchen for washing hands and vegetables. All three brands have 6-10 liter kitchen treasures, but the purchase depends on the size (location) of your kitchen. The price should be below 500. The water heater for bathing should be chosen according to the environment in which you use it. Don't buy one with a smaller liter capacity, otherwise you will be the one who gets the cold. Choose the specific brand according to your own preferences. If it is in liters and has some additional functions, go to a store and listen to the promotion staff to introduce it to you before making a decision. (I use Ariston at home, and it feels good. I have been using it for more than 5 years and there have been no problems.)
