An average house in the Northeast uses less than 700 gallons of fuel oil for heat and hot water for one year. The chart below shows the cost of other fuels providing the same.

The same home with either a System 2000^{®}, 90+ Resolute™, Resolute RT™, Ascent™ Combi, Ascent™ Combi Plus or Accel CS™ uses considerably less.
