Why doesn't cold water make a hot burner cold?
Heat is a form of energy and due to the principal of thermodynamic equilibrium, will constantly seek a state of equilibrium. The reason a hot burner does not become cold is because as the energy is transferred to the cold water more energy is being put into the burner through either electricity or gas. If there was no source of energy to the burner, then the cold water would cool down the hot burner, though the cold water would also heat up in the process, to the point where both are at room temperature.
