When your tank reaches 30 percent full, you should contact your propane vendor. Because of the limited propane supply, propane vendors are not able to fill tanks completely right now. They also need more advance notice on delivering propane to your home since there is a high demand for the heating fuel. If you wait to call until after your tank is below 30 percent, you may not be able to get propane delivered before your tank runs out.
If you have not yet applied for heating assistance, you can contact your county social service office or tribal government. You can also call toll-free 1-866-HEATWIS (432-8947) or visit homeenergyplus.wi.gov about where to apply for heating assistance through the WHEAP program.
