Should we charge for changing the nature of heating after household heating?

They don't care if the heating is changed, because they can't control it.

Go directly to the heating company to pay the heating fee during the heating period, and don't mention changing the heating at home. If it is not hot, go to the heating company to report it, or ask the regulatory authorities to monitor the indoor temperature. These have nothing to do with the property, and they are simply unfair to the heating company.

In addition, the heating company can't manage it, and there is no basis for the property to collect money. Ask them to show the official laws and regulations of government departments, or they will charge for a refund, or they will complain to the Consumers Association.
