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 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 solution. 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 generating hot water because of a gas line leak. If you detect a suspicious rotten egg aroma, assume you have a leak and follow these steps:

  • Close off the gas valves at your residence.
  • 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.
  • Contact 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 detect, but it’s a common cause of no hot water coming from a gas water heater. Start by checking the gas inlet valve and gas supply tube for leaks. If everything seems secure, inspect 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 have no hot water, the gas supply may be obstructed. Unfortunately, this might mean it’s time to purchase a new, more energy-efficient water heater. Contact a skilled plumbing specialist like Service Experts Heating & Air Conditioning to be sure.

3. The Pilot Light Is Out

The pilot light is essential for older gas water heaters to function effectively. If the light is out, you’ll have no hot water. Modern water heaters have glow plugs or spark igniters, so seek advice from your owner’s manual to find out 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 dissipate before trying to relight it. Call a professional for advice if you’re uncertain how to relight the pilot.

4. Thermostat Malfunction

Your water heater thermostat must be set correctly to furnish 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. 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 broken, getting a new one to replace it could be the best solution.

5. Sediment Buildup

Over time, sediment can build up in the bottom of the water heater tank. This buildup creates a barrier between the heating element or burner and the water, causing inefficiency and a potential lack of hot water. Sediment buildup is more prevalent in areas with hard water, but it can happen anywhere.

Routine maintenance, including flushing the tank at least once a year, helps prevent this issue. If the problem has already occurred, you might need professional assistance to clean or replace the tank. Keep an eye on the clarity and quality of your hot water in order to detect sediment buildup before it becomes a bigger problem.

6. Faulty Electric Water Heater

Electric water heaters are dependable components in the plumbing world, but even they sometimes experience 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 might be more cost-effective to replace the entire water heater rather than repair the problematic elements.

7. Undersized Water Heater

If the tank is too small for your household’s hot water needs, you may end 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 endless back-to-back showers.
