sizing heat exchanger and how water boiler

(OP)
It is desired to produce 15 liters / h of 92 % v/v ethanol using a still. This will be achieved by heating fermented juice (9.25 % v/v ethanol) in a 525 gallon tank operating at 440 gallons to which 2 stills are connected. It has been proposed to heat the 440 gallons of fermented juice from room temp to about 85 deg C using a heat exchanger in which hot water at 100 deg C will flow on the shell side. the heat exchanger must then maintain temp in the tank at about 85 deg C throughout the process. It is desired to size a heat exchanger for this duty and to size a hot water boiler (BTU/h) to produce hot water at 100 deg C. How would one go about it? Refer to attachment.

RE: sizing heat exchanger and how water boiler

(OP)
Or rather, let us forget about the heat exchanger and boiler and concentrate on the conceptual design of the optimal heating solution for this duty. I am a bit stranded on this one.
