Boiling point depends on the extend of Hydrogen Bonding,
In hydrogen fluoride, hydrogen bonding takes place hydrogen atom of one molecule and fluorine atom of other molecules.
In water molecules there are three atoms which participate in hydrogen bonding i.e. one oxygen and two hydrogen as compare to only two atoms in hydrogen fluoride.
​So, as the extend of hydrogen bonding is greater in water its boiling pint is also higher.
