"The ideal operating range is 20~80 PSI. The system also works great
on modified water systems such as a 12 volt pump."

Ideal operating range does not mean it needs to be that high. Isn't
the pressure enough for this kind of application if you get enough
water through ? I cant understand why it would absolutely need that
high pressure. It must have some kind of cut off for heating in order
to be able to handle slow discharge of heated water without
overheating.
