Is there a legal basis for the property charge for self-use wall-hung boiler heating?

Hello, according to common sense, you don't have to pay the heating bill. Since you use the wall-hung boiler to heat yourself, it means that you only occupy the floor heating pipe buried in advance when the developer builds it. Other water and gas appliances used for heating are all invested and used by themselves. If you charge, you can only say that it is managed by the developer, and it is impossible to pay this part of the fee every year. However, if the floor heating pipe is buried during the renovation, the property is not eligible to charge. I really haven't heard of this inscription. You can also consult in many ways. Hope to adopt. Thank you.
