7 Common Causes of No Hot Water

If you’re reading this, there’s a good chance it’s because you just had an icy cold shower or turned on the faucet and there wasn't any hot water. It’s a frustrating state of affairs, but don’t stress. Learning the most frequent causes of no hot water is the first step toward finding an answer. Here is a look at why you might be having hot water issues so you can get back to enjoying the hot showers you deserve.

1. Gas Leak

Do you have a gas water heater? It might not be producing hot water because of a gas line leak. If you notice a suspect rotten egg aroma, 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.
  • Call the fire department and your utility provider.
  • Do not ever 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 checking the gas inlet valve and gas supply tube for leaks. If everything seems secure, look at the gas valve to confirm it’s in the proper position and the gas is turned on. If the pilot light is functioning correctly but you still do not have hot water, the gas supply may be restricted. Regrettably, this could mean it’s time to purchase a new, more energy-efficient water heater. Contact a skilled plumbing specialist like Pardee Service Experts to be sure.

3. The Pilot Light Is Out

The pilot light is vital for older gas water heaters to work effectively. If the light goes out, there won't be any hot water. Newer water heaters use glow plugs or spark igniters, so consult your owner’s manual to see 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 dissipate before you try to relight it. Contact a professional for help if you’re uncertain how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat needs to be set properly to provide your home with adequate hot water. If you recently turned down the temperature to save 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 frequent reason for no hot water. If it turns out the thermostat is damaged, getting a new one to replace it might be the best option.

5. Sediment Buildup

Over time, sediment can build up in the base of the water heater tank. This buildup creates a blockage between the heating element or burner and the water, leading to inefficiency and could lead to no hot water. Sediment buildup is more prevalent in homes with hard water, but it can occur anywhere.

Regular maintenance, such as flushing the tank at least one time per year, helps protect against this issue. If the problem has already taken place, you could potentially need a specialist's assistance to clean or replace the tank. Monitor the clarity and quality of your hot water so you can catch sediment buildup before it becomes a larger issue.

6. Defective Electric Water Heater

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

If the breakers appear normal, the heating elements could be to blame. Water heaters typically last about 10 years, so if yours is getting older, it could be more cost-effective to replace the entire water heater rather than repair the faulty elements.

7. Undersized Water Heater

If the tank is not big enough to handle your household’s hot water needs, you may wind up running out of hot water. If you’re tired of lukewarm 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 countless back-to-back showers.
