Most states allow a maximum of 1,325 gallons to be stored in a single family residence. For homes with difficult access points (steep hills or long distances to the fill pipe over lawn and patios) the homeowner may choose to increase capacity to 400-gallons with a larger Roth tank or 550-gallons (2 Granby tanks connected ) to minimize the number of delivery. Winter deliveries can be difficult for fuel companies because of unplowed driveways and paths to fill pipes located behind a home. Reducing the number of deliveries per season may help reduce snow clearing required by the homeowner.
