1. Not only look at safety, but also look at regular maintenance. In addition to considering whether the manufacturer has 3C certification mark, whether there is grounding protection, anti-drying, anti-over-temperature, anti-overpressure device, etc., consumers should consider the safety caused by aging and wear after long-term use. Hidden dangers. It is recommended to select a water heater with regular maintenance functions such as “Smart Care Tipsâ€. 2. Not only look at descaling and cleaning, but also look at convenience. The product with the "Intelligent Maintenance Tips" function on the market can realize the "self-maintenance" of the water heater. It automatically sets the protective strength according to the water quality, actively releases protective ions, and neutralizes with the erosive ions in the water to protect the inner liner. When the anode rod consumption is too low, the electric water heater will have the words “need to be maintainedâ€, and the consumer will be reminded to take measures. 3. Not only look at the amount of water, but also the heating efficiency. It is best to choose the "two in one" product of fast heat and heat storage, so that you can continuously provide comfortable hot water and convenient bathing. Water heaters with "fast forward button" have been introduced on the market, and there are rapid thermal capacity and MAX capacity expansion systems. 4. Not only look at energy saving, but also look at intelligence. Choose an energy-saving electric water heater to start from three points: First, choose a product with rapid heating technology. Such as the market with "fast forward button", the speed of heat, heat storage as one of the electric water heater. The second is to select those products that meet the first and second energy efficiency labels. The third is to choose products that can be intelligent and energy-saving. The water heaters on the market have introduced AES adaptive energy-saving systems. 5. Not only look at the appearance, but also look at the insulation effect. When consumers choose products, they must look at the heat preservation effect of the water storage tank to reduce heat loss during standby and reduce the number of reheating and power consumption. Under normal circumstances, in the case of the same energy efficiency rating of the electric water heater, the thicker the insulation layer and the higher the density of the insulation material, the better the insulation performance. Some products now use a thermal insulation layer of cyclopentane, which not only has better insulation effect, but also has a more green material.
