We used 130 gallons last month, but that was a little more than usual because it was a touch colder than normal. Usually 150 gallons goes about 45 days. The house is a 24’X60’ raised ranch. We set the thermostat at 58–60 when we’re gone or in bed and 68 when we’re home. We also have an electric heater and an electric mock fireplace in the living room that work very well. The conmbination of the electric bill and the oil bill are less since we got the fireplace, plus it looks nice.
