In addition to heating, the stainless steel heat preservation water tank also plays an important role in heat preservation. The thermal insulation effect of the stainless steel thermal insulation water tank depends on the thickness of the thermal insulation layer (foam layer). The thicker the insulation layer and the wider the coverage, the better the insulation effect of the stainless steel insulation water tank. Now there are some inferior air energy water heaters on the market. The thickness of the insulation layer of the water tank is generally only 20-30mm, and the insulation layer is not installed at both ends of the water tank, so the insulation effect is definitely not ideal. Usually when the host stops working, the water will cool down quickly. Therefore, it is necessary to choose a water tank with a thermal insulation layer thickness of 40-50 mm and a 360-degree thermal insulation.

But many friends will say: You can't open the stainless steel insulation water tank when you buy it, and you can't see how thick the insulation layer is. Here is a reminder for everyone: the larger the water tank with the same capacity, the heavier the weight, indicating that the thicker the insulation layer is, the better the insulation effect will be.

     Control of the water temperature in the stainless steel insulated tank depends on temperature sensing light bulbs extending to all parts of the tank. The temperature sensing bulb can sense the temperature change and feed it back to the control center of the host. By measuring the real-time water temperature at each point through the temperature sensing package, the unit can provide hot water more stably and save energy. Therefore, the number of temperature sensors is critical. Currently, there are generally only two tank temperature sensors on the market: one for the tank inlet and one for the tank outlet. Some tanks even have only one outlet water temperature sensor. Therefore, the number of outlet water temperature sensors also has a great relationship with the thermal insulation performance of the stainless steel thermal insulation water tank.
