No Hot Water from Your Tank Heater
No hot water can be a pilot/igniter, thermostat, or heating element issue depending on gas or electric.
A tank water heater with no hot water has different likely causes depending on whether it's gas or electric.
Gas water heaters
Check that the pilot is lit (or the igniter is working) and the gas valve is on. A failed thermocouple, gas valve, or igniter commonly causes no hot water.
Electric water heaters
Check the breaker and the reset button on the upper thermostat. A failed heating element or thermostat is the usual cause of no hot water on electric units.
Key takeaways
- Gas: check pilot/igniter and gas valve
- Electric: check breaker and thermostat reset
- Failed elements are common on electric tanks
- Don't keep resetting a tripping element
