How much antifreeze needs to be added to a 60 gal capacity water boiler to make it not freeze at -10 degrees.
:
Using a chart for antifreeze concentrations, an 18 qt system requires 7 gt for protection down to -10 degrees.
:
7%2F18 = .39 (39% antifreeze)
:
therefore: .39 * 60 = 23.4 gal of antifreeze
;
Practically, from a full tank, drain 23.4 gal of water and add 23.4 gal of pure antifreeze
