- Make sure voltage is correct (240V required for most electric heaters)
Temperature inconsistencies might point to sediment buildup affecting your thermostat’s operation. Important Safety Note: The power at the circuit breaker must be off before you start any electrical diagnostics.
Gas System Troubleshooting
The thermocouple is often the root cause of performance problems in gas water heaters. This part signals the gas valve about the pilot light status. A dirty or worn thermocouple can make the pilot light go out.
Your gas system needs these checks:
- The pilot light status
- Gas pressure and supply levels
- Ventilation system condition
- Combustion air flow quality
Safety Warning: Leave the area immediately and call your gas company if you smell gas. Gas line repairs should only be done by professionals.
Energy Efficiency Solutions
You can substantially cut energy costs by improving your water heater’s efficiency. Your energy usage drops 6-10% just by setting the thermostat to 120 degrees.
The best efficiency comes from:
- Using low-flow fixtures that reduce hot water consumption
- Adding insulation to hot water pipes that prevents heat loss
- Getting an ENERGY STAR certified model that can save about $550 yearly on electric bills
Regular maintenance is a vital part of keeping efficiency high. The tank needs flushing twice a year to remove sediment that reduces heating effectiveness. Seattle residents in the Green Lake area can get professional maintenance services to keep their water heaters running at peak efficiency while meeting local regulations.
Water Quality Problems
Strange tastes, unusual colors, or unpleasant odors in your hot water might signal problems with your water heater. You can identify and fix these problems by knowing what these signs mean.
