I notice you are interested in monthly, winter vs summer, etc… basically we used 700 gallons in January and February, and 400 gallons for all of March through December combined. Roughly.

We have a well-insulated home of just under 2000 sq foot of heated space. We are very conservative, keeping thermostat around 62 for 16 hours a day, bumping up to 64 during day in a room when we are home. We used ~1100 gallons a year, which included heat, hot water, clothes dryer, and cooking. We have new heat pumps now… so looking forward, who knows? We’ll see.
