7 Common Causes of No Hot Water

If you’re reading this, it’s likely because you just had a shockingly cold shower or turned on the faucet to discover that your house doesn’t have hot water. It’s an irritating situation, but don’t panic. Learning the most common reasons your home has no hot water is the first step toward finding a remedy. Here is a review of the reasons why you might be having hot water troubles so you can get back to getting the hot showers you deserve.

1. Gas Leak

Does your home have a gas water heater? It might not be producing hot water because of a gas line leak. If you sense a suspicious rotten egg odor, assume you have a leak and follow these steps:

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

2. Gas Valve Failure

This hot water issue can be challenging to diagnose, but it’s a common cause of no hot water coming from a gas water heater. Begin by evaluating the gas inlet valve and gas supply tube for leaks. If everything seems intact, check out the gas valve to make sure it’s in the proper position and the gas is turned on. If the pilot light is functioning the way it should but you still have no hot water, the gas supply may be restricted. If that’s the case, this could mean it’s time to purchase a new, more energy-efficient water heater. Contact a trusted plumbing specialist like Service Experts Heating, Air Conditioning & Plumbing to be sure.

3. The Pilot Light Is Out

The pilot light is vital for older gas water heaters to operate properly. If the light is out, you won’t have any hot water. Newer water heaters use glow plugs or spark igniters, so seek advice from your owner’s manual to see if your unit has a pilot light. If that’s the case, you may need to turn off the regulator and wait for the gas to disperse before trying to relight it. Consult with a professional for assistance if you’re uncertain how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat needs to be set accurately to provide your home with adequate hot water. If you recently dialed down the temperature to use less energy while you were out of town, look at the thermostat to make sure it’s between 120 and 140 degrees F. Also, check for a tripped high-temperature cutoff switch, as this is a frequent reason for no hot water. If it turns out the thermostat is malfunctioning, replacing it might be the best remedy.

5. Sediment Buildup

Over time, sediment can accumulate in the base of the water heater tank. This buildup creates an obstruction between the heating element or burner and the water, contributing to inefficiency and could lead to no hot water. Sediment buildup is more frequent in areas with hard water, but it can occur anyplace.

Scheduled maintenance, such as flushing the tank at least one time per year, helps prevent this issue. If the problem has already occurred, you may need a specialist’s assistance to clean or replace the tank. Keep an eye on the clarity and quality of your hot water so you can detect sediment buildup before it becomes even more challenging to address.

6. Defective 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 could be the problem. 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 bad elements.

7. Undersized Water Heater

If the tank is too small for your household’s hot water needs, you may end up running out of hot water. If you’re sick and tired of putting up with tepid showers when you’re the last person to get ready in the morning, consider upgrading to a larger tank. You might also want to learn more about tankless water heaters, which heat water on demand for endless back-to-back showers.
