1.Temperature drop

If the pipeline to warm a lot of impurities, will be attached to the inner wall of the heating pipe, the heat dissipation, according to statistics for each additional thickness of 1mm wall, the indoor temperature will drop 6 ℃.

2.Energy consumption increased

Due to impurities impeding the heat dissipation, the natural room to reach the temperature of the reservation will need more heat energy consumption, so virtually increase.
