Unlike tankless water heaters, standard tank-type water heaters use an insulated storage tank. The construction or anatomy of this appliance is explained in the tutorial Anatomy of the Gas Water Heater.
Water heaters are generally very reliable but occasionally they do have problems.
- These problems can include:
- No hot water
- Inadequate hot water
- Rust colored water
- Rotten egg odor
- Low rumbling or popping noise
- Higher pitched whining
- Water leaking around base of heater
- Before any troubleshooting is done, make sure to prepare safely for the job by doing the following:
- Turn off power to an electric water heater. Do this by turning off the circuit breaker or fuse powering the heater.
- Turn the gas pilot control valve to "pilot" setting.
- Shut off the water supply to the water heater.
