Hot Water Heaters FAQs

Your water heater — it’s one of the most important appliances in your home that you never really think about. That is, until it gives out.

If you’ve got questions about your water heater, we’ve got answers!

Frequently Asked Questions About Water Heaters

1. How can I tell how old my water heater is?

Most water heaters have a manufacturer label on the side that includes an installation date. If the label or date is missing, you may be able to use the serial number to determine how old the unit is. If you know who installed the unit, you may even be able to call the company and ask them to check their records.

2. What are the signs that my water heater is about to give out?

No one wants to wake up one morning to find that they have no hot water. Instead of waiting until they day it’s completely given out, keep an eye out for these warning signs:

  • Rusting, either on the tank or in the water.
  • Strange noises.
  • Frequent leaks.

3. Why does my water heater make a “rumbling” noise?

A noise here and there, especially when your unit first turns on, is likely nothing to worry about. But if your unit is constantly rumbling, it likely means that sediment has built up on the bottom of the heater. The noise you’re hearing is water boiling as it’s trapped in the sediment, and means your unit isn’t working efficiently.

4. Why am I always running out of hot water?

This question can have a few different answers. Depending on your water needs and the number of people living in your house, it’s possible that your water heater isn’t large enough to meet your needs. Another reason could be because your unit is getting older and starting to give out.
