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 to find no hot water. It’s an annoying situation, but don’t panic. Learning the most likely reasons your home has no hot water is the first step toward finding an answer. Here are some of the most likely reasons why you might be having hot water challenges so you can get back to enjoying the hot showers you deserve.
1. Gas Leak
First, is this a situation where you have a gas water heater? It may not be producing hot water because of a gas line leak. If you detect a questionable rotten egg smell, 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.
- Never try to repair the gas line yourself.
2. Gas Valve Failure
This hot water dilemma can be tricky to detect, but it’s often the cause of no hot water coming from a gas water heater. Begin by inspecting the gas inlet valve and gas supply tube for leaks. If it all appears secure, inspect the gas valve to make sure it’s in the proper position and the gas is turned on. If the pilot light is operating properly but you still don’t have any hot water, the gas supply may be blocked in some way. Unfortunately, this might mean it’s time to invest in 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 necessary for older gas water heaters to function effectively. If the light is out, there won’t be any hot water. Recently manufactured water heaters feature glow plugs or spark igniters, so reference your owner’s manual to learn 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 you try to relight it. Call a professional for assistance if you’re confused about how to relight the pilot.
4. Thermostat Malfunction
Your water heater thermostat has to be set correctly to furnish your home with adequate hot water. If you recently turned down the temperature to use less 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 very common reason for no hot water. If it turns out the thermostat is broken, getting a new one to replace it could be the best option.
5. Sediment Buildup
Over time, sediment can accumulate in the lower part of the water heater tank. This buildup creates an obstruction between the heating element or burner and the water, causing inefficiency and could lead to no hot water. Sediment buildup is more common in homes with hard water, but it can occur anytime.
Scheduled maintenance, such as flushing the tank at least one time per year, helps avoid this issue. If the problem has already happened, you might need professional assistance to clean or replace the tank. Monitor the clarity and quality of your hot water so you can detect sediment buildup before it becomes a bigger problem.
6. Defective Electric Water Heater
Electric water heaters are reliable 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 may be the problem. Water heaters usually have a life span of about 10 years, so if yours is getting older, it could be more cost-effective to replace the entire thing rather than repair the problematic components.
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 every day, consider upgrading to a larger tank. You might also want to learn more about tankless water heaters, which heat water on demand for unlimited back-to-back showers.
