What Does It Cost to Run an Electric Water Heater in Texas?
This page estimates the energy-only cost to run an electric water heater in Texas using a standard electric resistance storage water heater, an average load of 4,500 watts, and a typical runtime of 2.5 hours/day.
Key metrics
| Metric | Value |
|---|---|
| Average wattage assumption | 4,500 W |
| Typical usage assumption | 2.5 hours/day |
| Estimated monthly electricity use | 337.5 kWh |
| Estimated monthly cost | $53.43 |
| Estimated yearly cost | $650.02 |
Electric Water Heater cost vs U.S. average
At the statewide average residential rate, running an electric water heater in Texas costs less per month by $5.87 than the same usage pattern priced at the current U.S. average electricity rate.
How much electricity does an electric water heater use?
This estimate uses a typical wattage range of 3,000-5,500 W and a modeling assumption of 4,500 watts for 2.5 hours/day. Using the formula kWh = (watts × hours) / 1000, that works out to 11.3 kWh per day, 337.5 kWh per 30-day month, and 4106.3 kWh per year.
Electric resistance water heaters cycle to maintain tank temperature and recover hot-water usage. Household size and hot-water demand drive most cost variability. In Texas, that energy is priced using the statewide residential average of 15.83 ¢/kWh, with a national benchmark of 17.57 ¢/kWh for comparison.
Electric Water Heater operating cost estimate in Texas
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 4.50 kWh | $0.71 |
| Per day | 11.3 kWh | $1.78 |
| Per month | 337.5 kWh | $53.43 |
| Per year | 4106.3 kWh | $650.02 |
These estimates isolate electricity usage only. Real utility bills can be higher because delivery charges, taxes, seasonal pricing, and fixed monthly fees are not included in this appliance model.
What changes the cost the most?
The biggest cost drivers for an electric water heater are the local electricity rate and real-world usage intensity. For this appliance, the main swing factors are tank size, household occupancy, inlet water temperature.
If your usage is lighter or heavier than the assumption on this page, the linked state calculator and usage-cost pages below are the fastest way to model a custom scenario with the same state electricity rate.
For calculator-focused intent, use the Electric Water Heater calculator in Texas to compare light, typical, and heavy usage profiles.

Rollout-enabled city context in Texas
These city pages provide supplemental local context for this same appliance usage profile. City values are deterministic estimates and remain secondary to the canonical appliance-state route.
| City | City rate | Monthly estimate | Yearly estimate | City route |
|---|---|---|---|---|
| Houston | 15.60 ¢/kWh | $52.65 | $631.80 | City electricity context |
| San Antonio | 16.50 ¢/kWh | $55.69 | $668.25 | City electricity context |
| Dallas | 16.50 ¢/kWh | $55.69 | $668.25 | City electricity context |
| Austin | 16.20 ¢/kWh | $54.68 | $656.10 | City electricity context |
| Fort Worth | 16.30 ¢/kWh | $55.01 | $660.15 | City electricity context |
| El Paso | 15.90 ¢/kWh | $53.66 | $643.95 | City electricity context |
City pages are authority/context routes and not appliance-by-city canonical pages. Appliance cost intent remains canonical at this state-level route.
