A higher boiling point means that the coolant can absorb more heat without turning into a gas, which is crucial for efficient heat transfer in the reactor. The statement about the boiling point being "8 times higher" refers to the boiling point comparison, not the specific heat capacity (which is +/- 3.4 times higher).
