How to drain the heater
With the advent of winter, the frequency of heating use increases, and many families may encounter the problem that the heating is not hot or is not hot locally. One common cause is the presence of air or impurities in the heating pipes, which prevents hot water from circulating properly. This article will explain in detail how to drain the heater to help you solve the problem of the heater not being hot.
1. Why do we need to turn on the water in the heater?
If there is air or impurities in the heating system, the hot water will not circulate properly, thus affecting the heating effect. The purpose of draining water is to discharge air and impurities in the pipes to ensure smooth flow of hot water and improve heating efficiency.
2. Preparation work before releasing water
Before you start draining water, you need to prepare the following tools and materials:
| Tools/Materials | Purpose |
