The status of traditional gas water heaters has been affected in the market due to factors such as safety and gas price increases. New electric water heaters have been replaced by new ones. Due to its longevity, high efficiency, energy saving, safety, and environmental protection, the market is immediately sought after. What kind of attention is paid to the purchase and use of electric storage-type electric water heaters ? Let Xiao Bian find out for everyone.
Storage-type electric water heaters are further divided into open and closed types. Early storage-type electric water heaters were mostly open or open type. Their simple structure, small size, relying on the pressure of spraying in high places, the water flow is small, but the price is low, suitable for small population, family Not very wealthy, only buying for bathing families. The electric water heater on the domestic market is mainly a closed storage type electric water heater. It does not need to be installed in separate rooms, does not produce harmful gases, is clean and hygienic, and can be easily temperature-regulated.
Storage water heaters classification
Electric water heaters are divided into three types: mechanical, digital display and numerical control according to their different control methods for water heating temperature.
1, mechanical control of electric water heaters
The main component of the temperature control of the mechanical electric water heater is a mechanical temperature control device for controlling a mechanical water heater of the electric water heater. The temperature controller is usually composed of a temperature measuring probe, an adjustable driving mechanism and a pair of electric contacts. When the temperature at the probe rises, the media (liquid or gas) in the probe expands and pushes the drive mechanism through the capillary, causing the electrical contact to act. The operating temperature of the electrical contact can be adjusted by an adjustable drive mechanism or the electrical contact can be normally open.
2, digital display type electric water heater (SX)
The digital type electric water heater control system is usually composed of a display board, a main control board, a strong electric board, and a temperature sensor.
Temperature, set temperature, fault code, and timing information can also be set using the buttons and knobs on the control panel. The main control board is the core of the control system and is used to control the temperature information and control the operation process of the water heater. Power plates are used to provide the power required by the system, perform strong electric drive, and detect leakage. Temperature sensors are used to collect temperature information.
3, digital electric water heater (SK)
The numerical control numerical control type electric water heater type electric water heater is composed of a display panel, a main control board, a strong electric board and a temperature sensor. The LCD display on the display board is used to display information such as working mode, heating status, current temperature, setting temperature, setting menu, clock, timing period, fault code, etc. It is also possible to use the keys on the board for setting operation. The main control board is the core of the control system. The over temperature detection and temperature detection temperature sensors are used to collect temperature information.
So how to buy a storage-type electric water heater?
Electric water heaters are divided into three types according to installation: wall-mounted horizontal, vertical wall-mounted and floor-standing. The horizontal wall-mounted water heater is horizontally hung on the wall when it is installed, and is suitable for a water heater whose capacity is not more than 100L, and has certain strength requirements for the wall.
1, select the capacity
The capacity of the water heater is in liters. The greater the capacity, the greater the capacity of the water heater for hot water supply. The user can select the capacity of the water heater according to the purpose, the size of the family population and the water usage. Below 15L water heaters are generally used for washing dishes in the kitchen, washing dishes or washing between the washings and brushing teeth. The water heater used for bathing should choose the capacity of 40L or more, 1 person use: 40~50L; 2 people use: 50~60L; 3 mouths of the family: 80~100L; family of more than 3 persons is suitable to choose the water heater of 120L above; You are accustomed to bathing with a bath, the best choice for water heaters above 150L.
2, select the power
The power of a water heater is measured in watts (W) or kilowatts (Kw) and usually refers to the power of an electric heating tube in a water heater. The greater the power, the more heat is generated per unit of time and the less heating time is required. The higher the load requirements. In the purchase of electric water heaters, users 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 cords to determine.
3, performance options
(1) Liner
The inner part of the water heater is the inner part of the water heater and directly affects the safety performance, service performance and working life of the water heater. When selecting the water heater, the user should be concerned about whether the material of the water heater inner liner is titanium-containing alloy, whether the thickness is sufficiently thick, whether the welding process is advanced and reliable, whether the quality of the enamel glaze is guaranteed, and whether the enamel sinter process is advanced or not.
(2) Electric heating tube
The quality of the electric heating pipe is directly related to the safe use of the water heater. Therefore, in the purchase of water heaters, in addition to concern about the size of the power of the electric heating pipe, it is more important to care about the electrical properties of the electric heating pipe.
(3) Magnesium anode rods (magnesium rods)
Magnesium is the lowest potential metal in electrochemical sequences and is physiologically non-toxic. Therefore, it is very desirable to use a magnesium rod to protect the bladder. Magnesium rod size is directly related to the length of protection liner and the size of the protective effect. The larger the magnesium rod, the better the protective effect and the longer the protection time.
(4) Selection of insulation layer
The insulation of the water heater directly affects the insulation performance of the water heater. The main factors that determine the insulation performance are insulation material and insulation thickness. Commonly used insulation materials are: asbestos, sponge, foam plastic, polyurethane foam and so on. Among these kinds of insulation materials, the polyurethane foam has the best insulation performance, the foam insulation performance is second, and the asbestos and sponges are difficult to be closely attached to the water heater because they are difficult to be used as a water heater auxiliary insulation material.
(5) Anti-backflow technology selection
In order to prevent electric water heaters from drying due to external water loss, all electric water heaters use anti-backflow technology. The anti-backflow technology used by most manufacturers is to use a safety valve with a non-return function (commonly known as a core-safe valve). However, the problem with this technology is that when the water heater is working, due to the thermal expansion and contraction of the water in the bladder, some of the water will leak into the pipeline through the internal leakage function of the valve core; at the same time, the safety valve The internal leakage function often fails due to clogging of scale, which increases the working pressure of the bladder and reduces the service life of the water heater.
