Your useage seems about normal.

I have a 2050sqft home and we use between 4 and 5 gallons a day through the winter.

Here’s a graph of our useage over the last month

We don’t have a wood stove or heat pumps though it would be a nice addition some day, but we still keep the temperature at 72, because I didn’t mortgage a $300,000 house just so I could feel like I was living outside.
