Open the valve before or after heating.

Open the valve before heating, find out the problems in the heating system in time and maintain it in time. For the heating system at home, whether it is floor heating or radiator, it is designed with pressure, which will be blocked, corroded or even leaked after long-term use. Testing water before formal heating can find out whether there is a problem with the heating system at home in time.

Opening the valve before heating can also exhaust the air in the heating system in time. Whether it's a newly built heater or a previously operated heater, there will be air in it. When testing water, open the valve to exhaust the air in the system, so that after formal heating, heating can be carried out at the first time, instead of exhaust, which leads to the problem of water shortage in the whole heating pipe network system.

In addition to the operation of opening the heating valve, the following matters should also be paid attention to when testing the water.

1, when water is tested, it is found that the heater leaks, so it should be repaired in time. The purpose of testing water is to find various problems in the heating system. If water leakage or even slight water seepage is found during water testing, it should be repaired in time. It is heating, and if it is repaired in time, it will not affect winter.

2. Try to exhaust when testing water. When the heater tests water, individuals usually do not need to exhaust air. If there is a problem with gas collection in the heater at home, then we can manually exhaust when testing the water, but we must be careful not to drain too much.

Don't take water from the heating. After testing the water in the heating system, the pipeline is filled with water with a certain pressure. We can't take water or drain water from the heating system. First of all, the water in the heating system generally contains chemicals and cannot be used. Secondly, excessive drainage will cause the water pressure in the heating system to drop, and even enter the air, affecting normal heating.

Don't touch the public heating valve. No matter during water testing or heating, individuals should try not to touch the heating valves on all public pipes. It's all decided by the heating company. It's all decided to turn off, turn on and turn off. If someone touches it, it may affect future heating. If necessary, you can find a heating company or property consultation and do it with their help.
