The working principle of the radiator: the temperature of the radiator will not exceed the temperature of the hot water running in the water pipe below. Although it is a new technology, it must follow the principle of heat transfer and the law of conservation of energy: the temperature of the heated object will not be higher than the temperature of the heat source, otherwise the energy will no longer be conserved. The temperature of the radiator will reach the same temperature as the hot water in the pipe, and will not exceed the temperature of the hot water. In practice, the radiator needs to dissipate heat to the surrounding space, so it will not reach the temperature of the hot water in the water pipe below. Some buyers may have questions: how much lower the temperature of the radiator can be than the water? There are many random factors in this question, and it is difficult to determine. It has a lot to do with the room temperature, the size of the room, and whether it is tight and not easy to dissipate heat. If the room temperature is low, the room space is large, and the sealing is not easy to dissipate heat, a large amount of heat from the radiator will radiate to the surrounding space, causing the radiator to have a much lower temperature than water.
