That’s just insane. The problem is not the cost of heating. The problem is that you are using too much of it.
Winter is winter. Embrace it. If you are wearing shorts and going barefoot inside your house in the winter then your house is too warm.
Lowering your thermostat 20 degrees will save you at least 20 percent. Set it to 60 degrees and get out that wonderful heavy winter clothing. It feels so good to wear it. A snuggly blanket on the couch is the best thing in the world. Enjoy winter and save big bucks. A cold house is a happy house.
