7 Common Causes of No Hot Water

If you’re reading this, it’s likely because you just had a breathtakingly cold shower or turned on the faucet to find no hot water. It’s a frustrating scenario, but don’t panic. Learning the most common things that leave you with 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 enjoying the hot showers you deserve.

1. Gas Leak

Does your home 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.
  • Contact 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 hard to diagnose, but it’s a common cause of no hot water coming from a gas water heater. Get started by checking the gas inlet valve and gas supply tube for leaks. If these both seem undamaged, check out the gas valve to ensure it’s in the correct position and the gas is turned on. If the pilot light is functioning properly but you still do not have hot water, the gas supply may be blocked in some way. Unfortunately, this may mean it’s time to get 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 function correctly. If the light is out, you’ll have no hot water. Modern water heaters feature glow plugs or spark igniters, so consult your owner’s manual to find out 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 air out before attempting to relight it. Call a professional for help if you’re confused about how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat must be set accurately to furnish your home with adequate hot water. If you recently lowered 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. Also, check for a tripped high-temperature cutoff switch, as this is a frequent reason for homes not having hot water. If it turns out the thermostat is broken, replacing it may be the best remedy.

5. Sediment Buildup

Over 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, contributing to inefficiency and a potential lack of hot water. Sediment buildup is more frequent in homes with hard water, but it can occur anyplace.

Scheduled maintenance, including flushing the tank at least annually, helps protect against this issue. If the problem has already happened, you could potentially need a specialist’s services to clean or replace the tank. Be mindful of the clarity and quality of your hot water in order to detect sediment buildup before it becomes even more challenging to address.

6. Malfunctioning Electric Water Heater

Electric water heaters are known as particularly solid 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 you don’t find any tripped breakers, the heating elements may be to blame. Water heaters typically have a life span of about 10 years, so if yours is getting older, it might be more cost-effective to replace the entire unit rather than repair the problematic elements.

7. Undersized Water Heater

If the tank is doesn’t have enough capacity to meet your household’s hot water needs, you may find yourself running out of hot water. If you’re sick and tired of putting up with lukewarm showers when you’re the last person to get ready every day, consider upgrading to a larger tank. You might also inquire about tankless water heaters, which heat water on demand for unlimited back-to-back showers.
