Insulated storage tank

An insulated storage tank, comprising:

• a plurality of arcuate-shaped insulating panels disposed in a circumferential pattern, the insulating panels each in contact with two other panels forming a cylindrical wall;
• an inner liner disposed within the cylindrical wall to be filled with a hot or cold liquid and conforming in shape to the insulating panels;
• an outer support jacket surrounding an exterior arcuate surface of the cylindrical wall of insulating panels, the outer support jacket;
• a substantially circular insulated tank lid disposed on the cylindrical wall and in contact with the inner liner to seal the liquid contained in the insulated storage tank;
• a control unit disposed on the tank lid;
• a water level sensor disposed on the tank lid and integrated with the control unit;
• and
• a temperature sensor disposed on the tank lid and integrated with the control unit;
• wherein the tank lid is divisible into first and second portions, each of the control unit, the water level sensor, and the temperature sensor being disposed a same one of the first or second portion such that the opposite one of the first or second portions can be opened without interfering with operation of any of the control unit, the water level sensor, or the temperature sensor.

A method for constructing an insulated storage tank, the storage tank including a plurality of insulating panels, individual ones of the insulating panels each including a leading edge contact surface forming a leading edge apex and a trailing edge offset, and an oppositely located trailing edge contact surface, an inner liner, an insulating lid, an insulating floor;

• and an outer support jacket, the method comprising:
• creating floor contact walls and floor support shelves in each of the insulating panels;
• slotting the insulating panels into position adjacent and on top of the insulating floor such that all of the insulating panels are placed around the floor having the leading edge contact surface and the trailing edge contact surface of proximate insulating panels abutting one another creating a cylindrical wall;
• inserting the inner liner into a cavity created by the insulating panels such that the inner liner covers the insulating floor and lines an inner circumference of the insulating panels;
• and
• placing the outer support jacket around an exterior arcuate surface of all of the insulating panels.
