How many gallons of water does a water heater hold?

Traditional water heaters are fickle friends in many ways. During heavy use, the 40- or 80-gallon reservoir can be emptied faster than it refills and heats, leaving someone in a cold shower. Heating and maintaining that much water at once isn’t very energy efficient, and if the heater suffers a catastrophic failure—that’s a lot of water pouring into your attic or garage.

How much does an electric water heater cost?

Electric water heaters are less expensive. In some cases, they can cost as little as $500. Base prices don’t usually include installation, however, so be sure to factor that in.
