7 Common Causes of No Hot Water
If you’re reading this, it’s likely because you just had an icy cold shower or turned on the faucet to discover that your house doesn’t have hot water. It’s a frustrating scenario, but don’t fret. Learning the most common causes of no hot water is the first step toward finding a remedy. Here are some of the most likely reasons why you might be having hot water issues so you can get back to getting the hot showers you deserve.
1. Gas Leak
First, is this a situation where you have a gas water heater? It may not be generating hot water because of a gas line leak. If you sense a suspicious rotten egg odor, assume you have a leak and follow these steps:
- Turn 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 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 issue can be hard to diagnose, but it’s a common cause of no hot water coming from a gas water heater. Start off by evaluating the gas inlet valve and gas supply tube for leaks. If everything seems undamaged, inspect the gas valve to ensure it’s in the right position and the gas is turned on. If the pilot light is working properly but you still have no hot water, the gas supply may be obstructed. Unfortunately, this may mean it’s time to invest in a new, more energy-efficient water heater. Contact a trusted plumbing specialist like Service Experts Heating, Air Conditioning & Plumbing to be sure.
3. The Pilot Light Is Out
The pilot light is vital for older gas water heaters to operate properly. If the light goes out, there won’t be any hot water. Modern water heaters feature glow plugs or spark igniters, so consult 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 dissipate before attempting to relight it. Consult with a professional for assistance if you’re uncertain how to relight the pilot.
4. Thermostat Malfunction
Your water heater thermostat needs to be set accurately to provide your home with adequate hot water. If you recently dialed down the temperature to conserve 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 frequent reason for a lack of hot water. If it turns out the thermostat is damaged, replacing it might be the best option.
5. Sediment Buildup
With time, sediment can build up in the lower part of the water heater tank. This buildup creates an obstruction between the heating element or burner and the water, contributing to inefficiency and the possibility you’ll have no hot water. Sediment buildup is more frequent in areas with hard water, but it can happen anytime.
Scheduled maintenance, which includes flushing the tank at least once a year, helps avoid this issue. If the problem has already occurred, you could potentially need a specialist’s help to clean or replace the tank. Monitor the clarity and quality of your hot water so you can identify sediment buildup before it becomes a bigger problem.
6. Faulty Electric Water Heater
Electric water heaters are reliable components in the plumbing world, but even they are not immune to problems. If your home doesn’t have 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 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 unit rather than repair the bad elements.
7. Undersized Water Heater
If the tank is doesn’t have enough capacity to meet your household’s hot water demands, you may end up running out of hot water. If you’re done dealing with not very hot showers when you’re the last person to get ready each morning, consider upgrading to a larger tank. You might also inquire about tankless water heaters, which heat water on demand for countless back-to-back showers.
