Aside from raising the boiling point, why is water pressure needed in a hydronic heat system?
If I have a 2 story house, boiler in basement, why should it have ~20psi?
Being a closed loop, there's minimal resistance to pumping water up ~25ft, as return water coming down is essentially pushing it up... right?
Or in the case of my heating system, the boiler is the highest point. It's set to ~10psi.
