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 situation, but don’t panic. Learning the most frequent reasons your home has no hot water is the first step toward finding an answer. Here is a review of the reasons why you might be having hot water troubles so you can get back to getting the hot showers you deserve.
1. Gas Leak
- Shut 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 attempt to repair the gas line yourself.
2. Gas Valve Failure
This hot water dilemma can be tricky to detect, but it’s a common cause of no hot water coming from a gas water heater. Start by evaluating the gas inlet valve and gas supply tube for leaks. If it all appears undamaged, look at 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 could 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 vital for older gas water heaters to function properly. If the light isn’t lit, you won’t have any hot water. Newer water heaters have 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 disperse before trying to relight it. Consult with a professional for assistance if you’re confused about how to relight the pilot.
4. Thermostat Malfunction
Your water heater thermostat must be set correctly to provide your home with adequate hot water. If you recently dialed 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. 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, buying a new one could be the best solution.
5. Sediment Buildup
With time, sediment can build up in the lower part of the water heater tank. This buildup creates a blockage between the heating element or burner and the water, causing inefficiency and could lead to no hot water. Sediment buildup is more prevalent in areas with hard water, but it can occur anywhere.
Regular maintenance, including flushing the tank at least annually, helps avoid this issue. If the problem has already happened, you could potentially need a specialist’s services to clean or replace the tank. Monitor the clarity and quality of your hot water so you can catch sediment buildup before it becomes a larger issue.
6. Defective 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 the breakers haven’t tripped, the heating elements may be to blame. Water heaters usually provide service for about 10 years, so if yours is getting older, it could be more cost-effective to replace the entire unit rather than repair the faulty hardware.
7. Undersized Water Heater
If the tank is too small for your household’s hot water needs, you may find yourself running out of hot water. If you’re done dealing with 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 countless back-to-back showers.
