Electric water heater purchase

How to choose an electric water heater that suits us? Xiaobian teach you a few tricks.

1. The storage-type electric water heaters are divided into two types: closed electric water heaters and open electric water heaters according to their export type. Enclosed electric water heaters have one or more valves at the outlet to control the amount of water and work under tap water pressure. This type of water heater has the advantages of flexible installation location, high outlet pressure and low heat loss. However, due to its liner working under pressure, thicker materials are required, and the manufacturing process requires high levels; the outlet of the open type electric water heater is open, and a valve on the inlet line controls the amount of water. Such water heaters work under normal pressure, so their liner production requirements are low, and the structure is relatively simple. At present, most manufacturers of electric water heaters are closed electric water heaters.

2. Electric water heaters can be divided into three types: horizontal wall-mounted, vertical wall-mounted, and floor-mounted, depending on the installation method. Wall-hung horizontal water heater is horizontally hung on the wall when installed. It is suitable for water heaters with a capacity of no more than 100L. It has certain strength requirements for the wall. When the wall-mounted vertical water heater is installed, it is vertically hung on the wall, suitable for capacity. Water heaters no larger than 100L have certain strength requirements for walls; Floor-mounted water heaters can be placed vertically on a solid floor, suitable for water heaters with a capacity of more than 100L.

3, the choice of electric water heater capacity The capacity of water heaters in liters (L) as a unit, the greater the capacity, the greater the water heater's heating capacity. At present, the common capacity on the market is: 10L, 15L, 40L, 50L, 60L, 80L, 100L, a few manufacturers can produce more than 100L products. The user can select the capacity of the water heater according to the purpose, the size of the family population and the water usage. 10L ~ 15L water heaters are generally used for washing dishes in the kitchen, washing vegetables or wash between the wash, brushing teeth, so people call it the image of the kitchen treasure or kitchen treasure. The water heater used for bathing should select a capacity of 40L or more, one person should use a water heater suitable for 40~50L; 2 people should use a water heater of 50~60L; 3 people should choose a water heater of 80~100L capacity; 3 More than 120L households are suitable for water heaters; if you are accustomed to using bath tubs, it is best to choose a heater that is more than 150L.

4, the choice of electric water heater power Water heater power in Watts (W) or kilowatts (Kw) as a unit, usually refers to the water heater electric heating tube power, the greater the power, the more heat generated per unit time, the required The less heating time, the higher the load on the wire.

At present, the power of the common water heaters on the market are: 1000W, 1250W, 1500W, 2000W, 2500W, 3000W and so on. In order to meet people's needs for the diversity of water heater products, dual-power electric water heaters have emerged in the market, and there are several combinations of 500W, 500W, 500W, 1000W, 1000W, 1000W, 1000W, 1500W, etc. for the user to choose, when the user is in use According to the need, choose to heat with a heating tube or two heating tubes simultaneously. The power of a water heater generally corresponds to the size of the capacity and has been determined by the manufacturer at the time of manufacture. Under normal circumstances, 10L ~ 15L choose 1000W ~ 1250W, 40L ~ 80L choose 1250W ~ 1500W, 100L or more to choose 2000W ~ 3000W. In the purchase of electric water heaters, the user should understand the size of the electric water heater, the power size of the choice should be based on the size of the cross-section of your home's electricity meters and power lines to determine the cross-section of the power cord below 1500W water heater should not be less than The cross-section of the 1.5mm2, 2000W~3000W water heater power cord should not be less than 2.5mm2. At the same time, it must be taken into account that the power cord is used exclusively for water heaters and used together with other appliances.
