Generally, a household heating has two pipes, one is the water inlet pipe and the other is the return pipe. Return pipe is generally a little colder than the inlet pipe, but it also has a certain temperature. If there is nothing wrong with your return pipe and water supply pipe, but return pipe is not hot at all, it means that there is air in the heating pipe at home, so it must be drained first, otherwise the heating effect will be affected, and the water in the pipe will not be very hot.

Precautions:
Try to keep a certain heat dissipation space near the indoor radiator. Don't pile up sundries on or in front of the radiator, otherwise it will affect the heat dissipation effect of the radiator.
The installation positions of radiators are designed by designers reasonably, which is beneficial to indoor heating and can ensure relatively balanced air supply. Air convection and indoor temperature, if changed, may cause indoor temperature imbalance. In addition, once the pipes and radiators are moved, it is easy to cause leakage, which not only causes economic losses, but also may be harmful to the body.
