I am reviewing the commissioning instructions for the Apricus solar DHW system. I note that the specified charging pressure for the glycol loop is 72.5 psi per the manual. This seems high compared to other systems I have experience with. Can anyone comment on 1) The science behind the high system charging pressure and 2) an off the shelf pump you use to achieve these pressures
