Answers to Your 3 Most Common Water Heater Questions

If you’ve ever wondered why your water heater isn’t working, how to fix it, or whether it’s time for an upgrade, you’re not alone! At Mister Water Heater, we’re here to help you keep the water heater in your Indianapolis home running smoothly. In this guide, we’ll answer three common water heater questions and share tips to keep your home’s hot water flowing.

1. What’s the Best Hot Water Temperature?

Maintaining the right temperature on your water heater is key for your comfort and safety. The ideal range for hot water is 122°F to 140°F, since temperatures below 122°F may allow dangerous bacteria like Legionella to grow in your water heater. Legionella bacteria can cause Legionnaires' disease, a serious lung infection that leads to coughing, fever, and difficulty breathing.

Keep in mind that setting the temperature too high can increase the risk of scalding, especially for children or the elderly. For water heater safety, check your thermostat regularly and adjust it as needed.

2. Why Don’t I Have Enough Hot Water?

If you’ve ever turned on the tap only to be greeted with cold water, the culprit could be as simple as heavy demand. If this is the issue, waiting 30–60 minutes for your tank to refill and reheat is usually all it takes.

On the other hand, if you're experiencing frequent hot water shortages, you may need to upgrade to a larger water heater or a tankless water heater that heats on demand. Here are a few things you can do to determine the problem:

• Check the Thermostat: Make sure it’s set to the optimal temperature range (122°F–140°F).

• Inspect the Pilot Light: If you have a gas water heater, check the pilot light and relight it if needed. Contact a professional if it won’t stay lit.

• Reset the Circuit Breaker: An electric water heater may need a reset if there was a power interruption.

If simple fixes don’t resolve the issue, it might be time to consider water heater repair or a new water heater installation.

3. What Is Causing My Water Heater to Leak?

Leaks are one of the most common signs of a problem with your water heater. Common causes include:

1. A broken or failing pressure relief valve, which regulates water pressure inside the tank.
2. Loose pipe connections, especially if water is leaking from the top of the heater.
3. An incorrectly installed temperature and pressure relief valve.
4. Cracks in the water heater tank, often due to corrosion or age.
5. A damaged drain valve which may require replacement.

If the issue is minor, repairs can often extend the life of your water heater. However, if your system is over 10 years old or frequently breaks down, replacing it with a new water heater is a wiser investment. Our team can guide you in choosing the best option for your home, including energy-efficient choices like hybrid or tankless water heaters.
