With the arrival of winter, heating has become an indispensable part of our lives. However, sometimes we encounter such a problem: the heating water is hot and the return water is not hot. Not only does this affect our comfort, but it can also cause damage to the heating equipment. So, what is the reason for this problem?And how to solve it?This article will give you a detailed answer.
1. The reason why the heating inlet and return water are not hot.
1.Unbalanced pressure of the heating system: When the water supply pressure of the heating system is greater than the return pressure, it will lead to the phenomenon that the inlet water is hot and the return water is not hot. This can be caused by a poor design of the heating system or a clogged pipe.
2.Blockage inside the radiator: The pipes inside the radiator are clogged, which can lead to poor water flow, which affects the transfer of heat. This condition can be caused by the radiator being used for too long and too much dirt has accumulated inside.
3.Faulty valves in the heating system: Faulty valves in the heating system can cause the direction of the water flow to change, which can affect the normal operation of the heating. This situation requires timely inspection and repair of the valve.
4.The water temperature of the heating system is too low: If the water temperature of the heating system is too low, it will also lead to the phenomenon that the inlet water is hot and the return water is not hot. This condition can be caused by reasons such as the boiler not functioning properly or the heating system not circulating well.
Second, the solution of heating inlet and return water is not hot.
1.Adjust the pressure of the heating system: First of all, you need to check whether the pressure of the heating system is normal. If the pressure is unbalanced, the problem can be solved by adjusting the speed of the pump or by installing a pressure regulator. At the same time, it is also necessary to check whether the pipeline is blocked, and if there is a blockage, it should be cleaned up in time.
2.Cleaning radiators: For the problem of internal blockage of radiators, the method of cleaning radiators can be used to solve it. First, close the valve of the heating system, and then open the drain valve of the radiator to drain the sewage inside. Finally, rinse the radiator with clean water until the water that comes out is clean.
3.Repair valves: For valve failures, they need to be inspected and repaired in time. If the valve is badly damaged, it may need to be replaced with a new one. During the maintenance process, it is necessary to pay attention to safety to avoid accidents such as electric shock.
4.Increase the water temperature of the heating system: If the water temperature of the heating system is too low, you can increase the water temperature by adjusting the operating parameters of the boiler. At the same time, it is also necessary to check whether the circulation of the heating system is smooth, and if there is a blockage, it should be cleaned up in time.
In short, the problem of heating inlet and return water not heating can be caused by a variety of reasons, which needs to be analyzed and solved according to the specific situation. In the process of solving, it is necessary to pay attention to safety and avoid damage to the heating equipment. I hope you find the above helpful and wish you a warm winter.
