How to solve the freezing of Wanhe water heater?

Wanhe water heater is frozen, and the following methods can be adopted:

1, external heating method. Steam, hot water, fire roasting, electric heating and other methods are used to melt the frozen ice in the pipe into water and discharge it to achieve the dredging effect;

2. In-tube heating method. Remove the pipeline and introduce steam, water, salt water, etc. Use a hose thinner than the pipeline to pump it into the pipeline to melt the ice in the pipeline and dredge the pipeline.

3. Usually, external heating method is used for thinner pipes, and internal heating method is used for thicker pipes;

In order to prevent the water pipe from freezing and blocking, the temperature around the water pipe must be kept above zero. If the conditions are limited, thermal insulation measures can be taken to keep the water in the pipeline flowing. For example, in cold weather, the valve is slightly opened to let water out.
