I am planing on buying 2 Solar Hot Water System to reduce the energy use of making ethanol at home. A 400 litre system with solar collector’s to heat a smaller tank only system of 160 litres with the aid of a vacuum pump to reduce the boiling point of ethanol to below 80 deg Celsius.

Has any one else done this?

Chris.
