Most domestic water heaters are quick heating type Intelligent thermostatic water heater 。
Convenient life brought by fast heating intelligent thermostatic water heater Brand choice: famous brand products have passed safety certification, good quality, and have Great Wall safety signs on the products. The enterprise has a reliable service network, and after-sales service is guaranteed. Counterfeit and shoddy products often use fake trademarks and packaging or fake assembly brands as imported original goods. Such commodities generally have a rough appearance, and the temperature rises slowly after power on, failing to meet the standard requirements.
Appearance inspection: the external surface of the product shall be painted evenly with bright color, without falling off, dents, serious scratches, extrusion marks, etc. Various switches and knobs shall be beautiful in shape, fine in processing, and the writing of dial shall be clear. Pay attention to the completeness of accessories, check the power plug, and ensure that the wiring is firm and intact without poor contact. It is better to conduct power on test and constant temperature performance inspection. First, check whether the indicator light is on and whether the water outlet power off indicator is reliable. During constant temperature inspection, set the temperature to a certain value. When the set value is reached, the fast heating intelligent constant temperature water heater can automatically power off or convert power. If the above requirements are met, the constant temperature performance of the fast heating intelligent constant temperature water heater is good, otherwise it is abnormal.
Selection of liner: stainless steel liner has high grade and long service life. The enamel liner is coated with a layer of fired inorganic ceramic glaze on the ordinary steel plate. If the manufacturing process is poor, the thickness of the glaze slurry attached to different parts of the liner will be uneven, and the porcelain is easy to fall off. The galvanized liner is coated with heat curing resin, and the zinc protective layer has poor rust resistance and short service life.
Selection of safety device: the fast heating intelligent constant temperature water heater shall generally be equipped with grounding protection, dry burning prevention, over temperature prevention and over pressure prevention devices. The high-grade water heater also has leakage protection, water free automatic disconnection and additional power off indication functions. The tank pressure rating of the water heater should generally be 0.75 MPa (different models have different ratings). When the tank pressure reaches the rated value, the overpressure protection device should reliably and automatically open the safety valve for pressure relief to ensure safety. The leakage protection device is generally required to cut off the power supply within 0.1 seconds when the leakage current reaches 15 mA.
Selection of insulation effect: products with large thickness of insulation layer and density of insulation materials shall be selected, which can be compared and selected according to the manufacturer's product instructions.
Constant temperature water heater performance: set the temperature to a certain value. When the set value is reached, the fast heating intelligent constant temperature water heater can automatically cut off power or convert power.
Capacity selection of water storage type quick heating intelligent constant temperature water heater: generally, the rated capacity is 30-40 liters, which is suitable for 3 to 4 people to continuously bathe; The 40~50 liter fast heating intelligent constant temperature water heater is suitable for 4~5 people to bathe continuously; The 70~90 liter fast heating intelligent constant temperature water heater is suitable for 5~6 people to bathe continuously.
