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 a frustrating state of affairs, but don’t fret. Learning the most frequent causes of no hot water is the first step toward finding a remedy. Here are some of the most likely reasons why you might be having hot water problems so you can get back to experiencing the hot showers you deserve.

1. Gas Leak

Do you have a gas water heater? It might not be making hot water because of a gas line leak. If you detect a questionable rotten egg odor, assume you have a leak and follow these steps:

  • Close off the gas valves at your home.
  • 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 attempt to repair the gas line yourself.

2. Gas Valve Failure

This hot water issue can be tricky to diagnose, but it’s often the cause of no hot water coming from a gas water heater. Start off by examining the gas inlet valve and gas supply tube for leaks. If these both seem intact, look at the gas valve to make sure it’s in the correct position and the gas is turned on. If the pilot light is operating properly but you still don’t have any hot water, the gas supply may be obstructed. Unfortunately, this may mean it’s time to purchase a new, more energy-efficient water heater. Contact an experienced plumbing specialist like Service Experts Heating, Air Conditioning & Plumbing to be sure.

3. The Pilot Light Is Out

The pilot light is essential for older gas water heaters to operate effectively. If the light is out, you’ll have no hot water. Modern water heaters use glow plugs or spark igniters, so reference your owner’s manual to see if your unit has a pilot light. If so, you may need to turn off the regulator and wait for the gas to disperse before trying to relight it. Call a professional for help if you’re unsure how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat needs to be set accurately to furnish your home with adequate hot water. If you recently turned down the temperature to conserve energy while you were out of town, check the thermostat to make sure it’s between 120 and 140 degrees F. As long as you’re looking at it, check for a tripped high-temperature cutoff switch, as this is a very common reason for homes not having hot water. If it turns out the thermostat is broken, getting a new one to replace it may be the best solution.

5. Sediment Buildup

With time, sediment can collect in the lower part of the water heater tank. This buildup creates a barrier between the heating element or burner and the water, causing inefficiency and the possibility you’ll have no hot water. Sediment buildup is more common in neighborhoods with hard water, but it can happen anytime.

Routine maintenance, including flushing the tank at least annually, helps avoid this issue. If the problem has already developed, you may need Expert assistance to clean or replace the tank. Monitor the clarity and quality of your hot water so you can detect sediment buildup before it becomes even more challenging to address.

6. Malfunctioning Electric Water Heater

Electric water heaters are reliable components in the plumbing world, but even they can have problems. If you notice there isn’t any hot water, examine 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 the cause of your hot water issues. Water heaters usually have a life span of about 10 years, so if yours is getting older, it could be more cost-effective to replace the entire thing rather than repair the faulty components.

7. Undersized Water Heater

If the tank is too small for your household’s hot water requirements, you may wind up running out of hot water. If you’re done dealing with lukewarm showers when you’re the last person to get ready every day, 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.
