7 Common Causes of No Hot Water

If you’re reading this, it’s probably because you just had an icy cold shower or turned on the faucet to find no hot water. It’s an irritating scenario, but don’t stress. Learning the most frequent things that leave you with no hot water is the first step toward finding a remedy. Here is a look at why you might be having hot water challenges so you can get back to enjoying the hot showers you deserve.

1. Gas Leak

First, is this a situation where you have a gas water heater? It might not be making hot water because of a gas line leak. If you sense a questionable rotten egg smell, assume you have a leak and follow these steps:

  • Shut off the gas valves at your residence.
  • Don’t switch any electrical appliances on or off.
  • Avoid smoking or using a lit match.
  • Open windows and doors for ventilation and evacuate the building.
  • Notify the fire department and your utility provider.
  • Never attempt to repair the gas line yourself.

2. Gas Valve Failure

This hot water problem can be challenging to identify, but it’s a frequent cause of no hot water coming from a gas water heater. Get started by checking the gas inlet valve and gas supply tube for leaks. If everything seems secure, inspect the gas valve to confirm it’s in the proper position and the gas is turned on. If the pilot light is operating correctly but you still have no hot water, the gas supply may be blocked in some way. Unfortunately, this could mean it’s time to invest in a new, more energy-efficient water heater. Contact a skilled plumbing specialist like McElroy Service Experts to be sure.

3. The Pilot Light Is Out

The pilot light is vital for older gas water heaters to function correctly. If the light is out, there won't be any hot water. Newer water heaters have glow plugs or spark igniters, so consult your owner’s manual to find out if your unit has a pilot light. If your water heater does have a pilot light, you may need to turn off the regulator and wait for the gas to disperse before you try to relight it. Call a professional for help if you’re confused about how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat needs to be set properly to supply your home with adequate hot water. If you recently turned down the temperature to save energy while you were out of town, look at the thermostat to make sure it’s between 120 and 140 degrees F. While you’re at it, check for a tripped high-temperature cutoff switch, as this is a common reason for no hot water. If it turns out the thermostat is damaged, buying a new one could be the best option.

5. Sediment Buildup

Over time, sediment can collect in the base of the water heater tank. This buildup creates a barrier between the heating element or burner and the water, contributing to inefficiency and the possibility you'll have no hot water. Sediment buildup is more prevalent in homes with hard water, but it can happen anyplace.

Regular maintenance, including flushing the tank at least annually, helps avoid this issue. If the problem has already developed, you could potentially need professional help to clean or replace the tank. Keep an eye on the clarity and quality of your hot water so you can identify sediment buildup before it becomes a larger issue.

6. Faulty Electric Water Heater

Electric water heaters are reliable components in the plumbing world, but even they sometimes experience problems. If you notice there isn't any hot water, look over the connections to the water heater and reset any tripped breakers at the electrical panel.

If you don't find any tripped breakers, the heating elements may be to blame. Water heaters usually provide service for about 10 years, so if yours is getting older, it might be more cost-effective to replace the entire unit rather than repair the problematic elements.

7. Undersized Water Heater

If the tank is too small for your household’s hot water needs, you may find yourself running out of hot water. If you’re tired of lukewarm showers when you’re the last person to get ready each morning, consider upgrading to a larger tank. You might also inquire about tankless water heaters, which heat water on demand for endless back-to-back showers.
