ahh well one could always go with a dual solenoid setup.........

I have a 120 volt 3/8" solenoid on my RO setup, never had an issue........

Yea I think dual solenoids can work then. Now there's the small issue of the heating element to be used. If aluminum PEX is safe for potable water contact on both the inside and outside coatings, that can work. Otherwise simple stainless steel tubes work just fine
