Why Is Your Hot Water Running Out Faster Than Usual?

There are several reasons why your hot water runs out quickly and does not last as long as it used to. Below are the most common issues that could be causing your hot water to run out too fast.
1. Sediment Buildup in the Water Heater Tank
One of the most common causes of hot water running out quickly is sediment buildup in your water heater tank. As water heats up, minerals such as calcium and magnesium settle at the bottom of the tank. Over time, this sediment layer builds up and takes up space that could otherwise be filled with hot water.
A water heater with too much sediment will have to work harder to heat the water, causing the hot water supply to deplete faster. You might notice that your hot water doesn’t last as long as it used to, even if the tank is full.
To fix this, you can flush your water heater to remove sediment. This should be done once a year to prevent buildup.
2. Worn-Out or Faulty Heating Element
If you have an electric water heater, the heating element may be the issue. Over time, the element can wear out or become less effective. When this happens, the water heater struggles to heat the water, leading to your hot water running out quickly.
Gas water heaters can face similar problems with their burners or pilot lights. If either of these is malfunctioning, the water heater won’t be able to heat the water properly, and you’ll have your hot water running out quickly.
In this case, the heating element will need to be replaced. This is a more technical repair, so it’s best to call Neighbourhood Plumbing to replace the faulty part. Once replaced, your water heater should be able to keep up with your hot water demands again.
3. Your Water Heater is Too Small
If your hot water is running out faster than you’d like, it could be that your water heater is simply too small for your household’s needs.
Maybe your family has grown, or you’ve added new appliances that use hot water. A water heater that’s too small won’t be able to keep up with high demand.
If your water heater is undersized, the only solution is to upgrade to a larger model based on your household’s hot water usage. This upgrade is worth the investment for long-term comfort.
4. Incorrect Thermostat Settings
Your water heater’s thermostat controls how hot the water gets. If it’s set too low, the water heater will stop heating the water too early, leaving you with your hot water running out quickly. If the setting is too high, it can lead to scalding water and wasted energy.
Check the thermostat on your water heater. Ideally, it should be set to 120°F (49°C), which is hot enough for most household needs.
If it’s set lower than this, try raising the temperature slightly. Be cautious not to set it too high, as excessively hot water can be dangerous.
5. Leaks in the Hot Water System
If you’ve noticed that your hot water runs out quickly, it could be because of a leak somewhere in your system. Even a small leak can reduce the amount of hot water that reaches your taps. Leaks can occur in the tank itself or in the pipes leading from the water heater.
Check around your water heater for any visible signs of leaks. If you can’t find the source of the leak, you may need to contact Neighbourhood Plumbing to inspect the system.
Leaking water not only reduces the amount of hot water available but can also cause damage to your home over time.

6. Aging Water Heater
If your water heater is more than 10-15 years old, it’s probably nearing the end of its life. As water heaters age, they become less efficient at heating water, meaning you’ll run out of hot water faster.
If your water heater is getting old, it may be time to replace it. Newer models are more energy-efficient and can provide a more consistent supply of hot water. Replacing an old water heater may seem like a big investment, but it can save you money on energy bills in the long run.

If you’ve tried addressing the common issues and your hot water still runs out too fast, here are a few other steps you can take to improve the situation:
1. Upgrade to a Tankless Water Heater
Consider upgrading to a tankless water heater. These systems provide hot water on demand, so you’ll never run out, no matter how much hot water you use.
It’s a great option if your household’s hot water usage is high.
2. Insulate Your Water Heater
If your water heater is located in a cold area, like the garage or basement, the water in the tank might be cooling down faster than expected.
Insulating the water heater can help maintain the temperature and keep the water hotter for longer.
3. Stagger Hot Water Usage
If multiple people in your home use hot water at the same time, it can deplete the tank quickly. Try to stagger showers, laundry, and dishwashing to spread out the demand on your water heater.
4. Fix Low Hot Water Pressure
Sometimes, the issue isn’t the amount of hot water available but low water pressure. If your water pressure is too low, it might feel like the hot water is running out, even when there’s plenty left in the tank.

If your hot water runs out, the recovery time depends on your water heater’s size and type. For electric water heaters, it can take 30 minutes to an hour to fully reheat the water.
Gas water heaters usually recover faster, taking about 20-30 minutes. If it’s taking much longer than this, it could indicate a bigger problem, like a faulty heating element or an issue with the thermostat.
Conclusion
Running out of hot water quickly can be a nuisance, but it’s often a fixable problem. Whether it’s flushing the tank, upgrading your water heater, or addressing leaks, there are plenty of solutions to get your hot water supply back on track.
Regular maintenance and timely repairs can go a long way in ensuring you always have enough hot water for your needs.
