1. Insulation layer

In addition to water storage, the water tank has another important function-heat preservation. The quality of the heat preservation effect is affected by the thickness and coverage of the heat preservation layer. The thicker the heat preservation layer and the wider the coverage, the better the heat preservation effect. Therefore, when purchasing, the best insulation layer thickness of the water tank is 40~50mm, and it has a 360-degree insulation function. When the water tank capacity is the same, the larger and heavier the water tank, the thicker the insulation layer. Of course, the better the heat preservation effect.

Second, the quality of the inner tank

The quality of the inner tank determines the long-term use of the water tank. According to the different materials used, the water tank of the air energy water heater can be divided into three categories: crystal inner tank, enamel inner tank, and stainless steel inner tank.

1. The water tank made of crystal liner is low in cost, but the plastic layer of the bladder wall will produce peculiar smell when it is in contact with water for a long time. It is not suitable for household air energy water heaters, so it is mostly used for industrial water heater tanks.

2. The quality of the enamel tank depends on the quality of the enamel process. The core technology of enamel is in the hands of European and American companies. The domestic enamel technology is relatively rough. Therefore, there are not many products with good quality for enamel tanks.

3. Nowadays, many manufacturers use 304 stainless steel to make the inner tank of the water tank, which has the characteristics of corrosion resistance and excellent welding, and has high water storage and heat preservation efficiency. It is widely used in the current air energy water heater water tank.

Third, the temperature sensor

The temperature sensor controls the water temperature of the water tank. The function of the temperature sensor is to sense the temperature change, and then feed it back to the host control center. The number and sensitivity of the temperature sensing bulb are directly related to whether the hot water can be stably supplied and whether the energy saving effect can be achieved. At present, most water tanks on the market use two temperature sensing bulbs, but some manufacturers have begun to develop water tanks with three or more temperature sensing bulbs.
