At a glance
A 50 gallon electric water heater is the most common electric size for families in San Antonio. Electric tanks reheat more slowly than gas, so households usually choose one size larger than they would with gas.
An electric water heater heats water with an upper and a lower element, controlled by two thermostats. There is no flame or vent, which makes electric tanks simple to install in closets and garages.

Other sizes
Smaller households and tight spaces often use a smaller tank.
| Size | Typical household | Notes |
|---|---|---|
| 30 gallon electric | 1 person, or a casita | Short and tall versions available |
| 40 gallon electric | 1 to 2 people | Fits most closets |
| 50 gallon electric | 3 to 4 people | The most common family size |
| 65 to 80 gallon electric | 5 or more people | Check floor space and circuit size |
Troubleshooting
An electric water heater not heating usually comes down to power, the reset button, an element or a thermostat.
Check the breaker. Then the red high-limit reset button behind the upper panel. If it trips again, the plumber needs to find out why.
Usually a failed lower element or its thermostat. Sediment around the lower element speeds up failure in hard water.
A stuck thermostat. This is a safety issue; turn the power off and call a plumber.
Repairs
Electric water heater repair most often means element replacement or thermostat replacement. Both are common, low-part repairs once a plumber confirms which part failed with a meter. A leaking tank, however, needs replacement. See the repair page for other symptoms.

Homeowner questions
Commonly about 10 to 15 years. Element failures are common in hard water but are repairable.
A shorted element, damaged wiring or a failing thermostat. Do not keep resetting it; have a plumber test the unit.
If you have the space and a warm garage, a heat pump water heater can cut electric use substantially. It needs airflow and a condensate drain.
