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 an annoying scenario, but don’t stress. Learning the most likely 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 problems 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 making hot water because of a gas line leak. If you notice a questionable rotten egg smell, 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 so the gas can disperse and evacuate the building.
- Contact 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 challenging to diagnose, but it’s a common cause of no hot water coming from a gas water heater. Get started by inspecting the gas inlet valve and gas supply tube for leaks. If everything seems undamaged, inspect the gas valve to make sure it’s in the proper position and the gas is turned on. If the pilot light is functioning the way it should but you still do not have hot water, the gas supply may be restricted. Regrettably, this may mean it’s time to get a new, more energy-efficient water heater. Contact a skilled plumbing specialist like Comfort Masters Service Experts to be sure.
3. The Pilot Light Is Out
The pilot light is vital for older gas water heaters to function correctly. If the light isn't lit, you’ll have no hot water. Recently manufactured water heaters feature glow plugs or spark igniters, so reference 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 disperse before attempting to relight it. Consult with a professional for assistance if you’re unsure how to relight the pilot.
4. Thermostat Malfunction
Your water heater thermostat has to be set properly to supply your home with adequate hot water. If you recently dialed 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. 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 malfunctioning, buying a new one might be the best remedy.
5. Sediment Buildup
Over time, sediment can collect in the bottom of the water heater tank. This buildup creates a barrier between the heating element or burner and the water, leading to inefficiency and could lead to no hot water. Sediment buildup is more frequent in neighborhoods with hard water, but it can take place anywhere.
Scheduled maintenance, including flushing the tank at least one time per year, helps prevent this issue. If the problem has already taken place, you could potentially need Expert help to clean or replace the tank. Monitor the clarity and quality of your hot water in order to catch sediment buildup before it becomes a larger issue.
6. Malfunctioning 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, examine 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 might be to blame. Water heaters typically provide service for about 10 years, so if yours is getting older, it may be more cost-effective to replace the entire unit rather than repair the problematic elements.
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 tepid 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.
