During the use of the heater, we may encounter situations where we need to drain water, such as cleaning the radiator, replacing the radiator, etc. There is one step that is very important in this process, and that is to close the return pipe. So why do we need to turn off the return pipe when the heating is draining? This article will give you a detailed answer.
First of all, we need to understand how the heating system works. The heating system is mainly composed of four parts: heat source, pipes, radiator and control system. The heat source is usually a boiler or wall-hung boiler, which generates heat by burning fuel, and then transfers the heat through the pipe to the radiator, which dissipates the heat into the room and raises the indoor temperature. The return pipe is the pipe that re-transports the cooled water from the radiator back to the heat source for heating.
When we need to drain the water from the heating system, if the return pipe is not closed, the cooling water in the radiator will flow back to the heat source through the return pipe, which will cause the hot water in the heat source to be cooled, which will affect the heating effect of the heat source, so that the indoor temperature can not reach the expected set value.
Second, closing the return pipe can avoid wasting hot water. In heating systems, hot water is produced after heating from a heat source, a process that consumes a lot of energy. If we don't close the return pipe during the discharge process, then the hot water will continue to flow back to the heat source, which will cause the heat source to continuously heat the cooled water, resulting in a waste of energy.
In addition, turning off the return pipe can protect the safety of the heating system. During the water discharge process, if the return pipe is not closed, then the cooling water in the radiator may flow back to the heat source, which may cause the hot water in the heat source to overheat, which can cause a safety incident.
Finally, shutting down the return pipe can avoid damage to the heating system. During the draining process, if the return pipe is not closed, then there is a possibility that the cooling water in the radiator will flow back to the heat source, which may cause the hot water in the heat source to overheat, which can cause damage to the heating equipment of the heat source.
To sum up, we need to close the return pipe when the heating water is discharged, mainly to avoid affecting the heating effect of the heat source, avoiding hot water waste, protecting the safety of the heating system and avoiding damage to the heating system. Therefore, we must remember to close the return pipe when we are performing the heating water discharge operation. Publish a collection of dragon cards to share millions of cash
