Run the vehicle. The vehicles alternator charges the battery, which then provides the inverter with DC current. The AC current, which is provided by the inverter can be accessed with a simple extension cord, which makes it available to what ever appliances or lighting you choose.
To use the emergency power kit to provide electricity to a heating system, other than electric heat, an electrician should probably be consulted. Electric heating systems use more watts than an inverter can provide.
