Is there any worse way to start your day than having your morning shower suddenly turn ice cold, especially if you still have shampoo to rinse out of your hair?
Hot water is one of those modern conveniences that we all take for granted — until we suddenly don’t have it. At Cubby Oil & Energy, our team of home comfort specialists regularly assists homeowners in the Boston area with their water heater concerns. Here are four common reasons that you might run out of hot water suddenly, as well as some ways to address the problem.
If you’re running a dishwasher and a load of laundry on a hot setting simultaneously, it might not come as much of a surprise that your shower would run out of hot water. This could also be an issue if you’re in a home where several family members need to bathe in quick succession. The tank of hot water will eventually get depleted and need to be recovered.
The simplest DIY solution is typically to stagger how you utilize your hot water appliances and fixtures. Of course, this can become aggravating when you’re corralling a big household. It’s also possible that your current water heater isn’t the proper size for your needs. You can talk to us about potentially upgrading to a model with a larger tank or even an on-demand system.
Another frequent issue leading to hot water loss is that your water heater’s temperature is set too low. If your water isn’t coming out hot enough, you can end up depleting it quicker. Try setting the water heater a few degrees higher and see if that fixes the problem.
Over time, sand, rust and other loose minerals build up in water heater tanks. While some sediment is normal, too much can take up space and reduce the amount of available hot water. It can also insulate the tank bottom, making it harder to heat the water efficiently.
To prevent issues, flush your water heater every year, either by yourself or with a professional. The process is simple: turn off the burner and close the cold-water inlet valve, attach a hose to the drain valve and empty the tank. Then, flush it with fresh water, close the drain valve and refill the tank.
If your water heater is over 10 years old and not providing sufficient hot water, then it’s time to start exploring replacements. The last thing you want is for your current unit to fail on you, leaving you without hot water and potentially with a decent amount of water damage. Our team is ready to help identify a great, highly efficient unit and install it promptly.
