If the residential property cannot be heated during the heating period, how much should it be subsidized?

It depends on whether the property is responsible for heating.

The property is responsible for heating and has signed a heating agreement with the owner. If heating is not provided as agreed, the property shall bear the liability for breach of contract.

If the heating is not provided by the property, but by the municipal government or other units, the property will not be responsible.

Heating is also a kind of consumption. Owners also have to pay for heating. If the heating party cannot supply heat, but does not charge heating fees, there is no subsidy for the owners. If the heating fee is charged, but there is no heating, the owner can sue the heating unit and demand the return of the heating fee.
