That sounds about right. A friend of mine has an airtight 3000 SF home (Bensonwood built). Closed foam insulation, airtight with heat exchanger home with condensing boiler/on-demand hot water. He also has a gas stove/oven, fireplace, and outside grill. In the winter the wind whip through the bay up to his home, but not a big issue. The home is heated up to 67 degrees in the winter. The house is so efficient, that the radiant heat on the basement floor was sufficient enough to keep the whole house warm. Even on the coldest night, there is only a few degrees difference on the second floor!
Built in 2014, the average use was about 1250 gallons a year!
