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 and there wasn’t any hot water. It’s an annoying scenario, but don’t stress. Learning the most frequent things that leave you with no hot water is the first step toward finding a solution. Here are some of the most likely reasons why you might be having hot water issues so you can get back to experiencing the hot showers you deserve.

1. Gas Leak

Do you have a gas water heater? It may not be making hot water because of a gas line leak. If you sense a suspect rotten egg aroma, assume you have a leak and follow these steps:

  • Turn 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 so the gas can disperse 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 dilemma can be difficult to identify, 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 it all appears undamaged, look at the gas valve to ensure it’s in the right 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 blocked in some way. Unfortunately, this could 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 work correctly. If the light goes out, you won’t have any hot water. Modern water heaters have 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 air out before you try to relight it. Consult with a professional for help if you’re uncertain how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat must be set correctly to supply your home with adequate hot water. If you recently turned down the temperature to use less energy while you were out of town, examine 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 homes not having hot water. If it turns out the thermostat is malfunctioning, buying a new one may be the best option.

5. Sediment Buildup

After awhile, 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, contributing to inefficiency and a potential lack of hot water. Sediment buildup is more common in homes with hard water, but it can happen anytime.

Scheduled maintenance, including flushing the tank at least annually, helps prevent this issue. If the problem has already happened, you could potentially need Expert assistance to clean or replace the tank. Keep an eye on the clarity and quality of your hot water to detect sediment buildup before it becomes a bigger problem.

6. Malfunctioning Electric Water Heater

Electric water heaters are known as particularly solid components in the plumbing world, but even they can have problems. If you notice there isn’t any 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 could be the cause of your hot water issues. Water heaters typically last about 10 years, so if yours is getting older, it may be more cost-effective to replace the entire water heater rather than repair the problematic hardware.

7. Undersized Water Heater

If the tank is not big enough to handle your household’s hot water requirements, you may find yourself running out of hot water. If you’re done dealing 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.
