7 Common Causes of No Hot Water

If you’re reading this, there’s a good chance it’s because you just had a breathtakingly cold shower or turned on the faucet to find no hot water. It’s an annoying scenario, but don’t fret. Learning the most likely reasons your home has no hot water is the first step toward finding a solution. Here is a look at 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 may not be making 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:

  • Close 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 for ventilation and evacuate the building.
  • Notify the fire department and your utility provider.
  • Do not ever try to repair the gas line yourself.

2. Gas Valve Failure

This hot water problem can be tricky to diagnose, but it’s a common cause of no hot water coming from a gas water heater. Begin by examining the gas inlet valve and gas supply tube for leaks. If these both seem secure, look at the gas valve to confirm it’s in the right position and the gas is turned on. If the pilot light is working the way it should but you still don't have any hot water, the gas supply may be obstructed. Unfortunately, this might mean it’s time to invest in a new, more energy-efficient water heater. Contact a skilled plumbing specialist like All American Air Service Experts to be sure.

3. The Pilot Light Is Out

The pilot light is necessary for older gas water heaters to operate correctly. If the light isn't lit, you’ll have no 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 so, you may need to turn off the regulator and wait for the gas to dissipate before attempting to relight it. Consult with a professional for assistance if you’re confused about how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat has to be set correctly to furnish your home with adequate hot water. If you recently dialed down the temperature to use less energy while you were out of town, check 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 very common reason for a lack of hot water. If it turns out the thermostat is damaged, replacing it may be the best remedy.

5. Sediment Buildup

With time, sediment can accumulate in the lower part of the water heater tank. This buildup creates a blockage between the heating element or burner and the water, causing inefficiency and could lead to no hot water. Sediment buildup is more frequent in neighborhoods with hard water, but it can occur anytime.

Routine maintenance, such as flushing the tank at least once a year, helps avoid this issue. If the problem has already developed, you might need professional assistance 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 even more challenging to address.

6. Defective Electric Water Heater

Electric water heaters are dependable components in the plumbing world, but even they are not immune to problems. If you’re experiencing no hot water, check the connections to the water heater and reset any tripped breakers at the electrical panel.

If the breakers haven’t tripped, the heating elements might be the problem. Water heaters generally last about 10 years, so if yours is getting older, it may be more cost-effective to replace the entire thing rather than repair the faulty hardware.

7. Undersized Water Heater

If the tank is too small for your household’s hot water demands, you may wind up running out of hot water. If you’re sick and tired of putting up with not very hot showers when you’re the last person to get ready in the 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.
