Oil boils at a higher temperature than water which means that when water is poured into boiling oil it is heated to, and past, the boiling point very quickly. 2x above the pressure rating will turn your water heater into a rocket. What keeps the rate of burning in check is the rate at which oxygen can reach the burning oil surface. This really isn't much of an answer; it would be better if you could expand this to cover what heat transfer does (e.g., the rapid change indicates X). More precisely, its due to the difference in their temperature and due to vigorous transfer of thermal energy from hot oil to cold water where water instantly changes its state into vapour. Normally, your water heater shuts off or releases the built-up pressure through a safety valve. According to the textbooks, these reactive electrons rip apart the surrounding water molecules to release hydrogen gas and heat.
