Can a Broken Water Heater Cause High Electric Bills?

How an Inefficient Water Heater Raises Your Energy Bills

Water heaters can drive up energy bills when they run inefficiently, using more energy to produce the same amount of hot water as a newer, well-maintained unit. Over time, sediment builds up in the tank, reducing its capacity and forcing the heater to work harder and longer to heat water. Worn-out components, such as heating elements or thermostats, can also cause the system to use more energy than necessary. The result is higher utility bills and added strain on your household budget.

Signs Your Water Heater Needs Repair or Replacement

Water heaters are often tucked away in basements or closets, which makes it easy to miss a problem. It’s a good idea to check on yours a few times a year and take note of anything out of the ordinary. Here are some common warning signs:

• Inconsistent hot water: You run out of hot water faster than usual, or the temperature changes while you’re using it.
• Water that’s too hot or too cold: The temperature doesn’t match what you expect, even after adjusting the tap.
• Dirty or smelly water: Rusty, cloudy, or foul-smelling hot water can point to sediment or corrosion inside the tank.
• Rumbling or popping noises: These sounds often mean sediment has built up at the bottom of the tank.
• Water leaks: Moisture or puddles around the base of the unit are a sign to act quickly.
• Old equipment: Water heaters that are 10–15 years old or older are often less efficient and more likely to fail.

DIY Water Heater Troubleshooting Tips

If any of these signs sound familiar, a few quick checks can help you learn more about the problem. They’ll also help you prepare for a professional technician if you need one.

1. Check the thermostat setting. An improperly set water heater can make your water feel too hot or too cold. The generally recommended temperature range is 120–125°F.
2. Check the circuit breaker. Electric water heaters should have a dedicated circuit breaker. If it has tripped, flip the switch back to ON. If it keeps tripping, contact a professional.
3. Check the pilot light. Gas water heaters need the pilot light lit at all times. If it has gone out and you don’t smell gas, you can try relighting it by following the manufacturer’s instructions on the unit. If you smell gas, leave your home immediately and call your gas provider from a safe location so they can shut off the supply until the issue is resolved.
