If a gas water heater has no hot water, the pilot, thermocouple or gas valve is the usual cause; on an electric heater it's usually an element or thermostat.

No hot water? What to check first
On a gas water heater, check that the pilot is lit and the gas valve is on. On an electric heater, check the breaker and the high-limit reset button. If the pilot won't stay lit, the breaker trips again, or you smell gas, stop and call a plumber.
Costs & planning
Repair or replace your water heater?
Repair when a replaceable part failed on a heater under about 8 years old. Replace when the tank itself leaks, the heater is past 10 to 12 years, or repairs keep adding up. A leaking tank can't be repaired.
