How Much Does It Cost to Run a Electric Water Heater in New York? (2026)
A tank water heater is often the single largest electricity user in a home without electric heating. The element only runs a few hours a day, but at 4,000 watts or more those hours add up fast.
A typical electric water heater (4,000 W) costs $1.16 per hour, or about $104.40 per month at 3 hours a day in New York. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (3,000 W) | $0.87 | $2.61 | $78.30 | $952.65 |
| Typical (4,000 W) | $1.16 | $3.48 | $104.40 | $1,270 |
| High (5,500 W) | $1.59 | $4.78 | $143.55 | $1,747 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 3 h/day ≈ 4,380 kWh per year.
In New York, with electricity at $0.29 per kWh (source: EIA Table 5.6.A, 2026-06), a typical electric water heater costs $1.16 per hour and about $1,270 per year at 3 hours a day. That is about 61% more than the US national average of $64.80 per month, because electricity in New York costs $0.29 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 0.9 hours of use.
How to lower the cost of running a electric water heater
- Set the thermostat to 120 F (49 C). Factory settings are often 140 F.
- Insulate the tank and the first few feet of hot water pipe.
- Fix dripping hot taps. A slow drip can waste hundreds of litres of heated water a month.
- A heat pump water heater uses about a third of the electricity of a resistive tank.
Frequently asked questions
How many hours a day does a water heater run?
Typically 2 to 4 hours of element time, depending on household size and shower habits.
Is a tankless water heater cheaper to run?
It avoids standby losses, saving 10 to 30 percent, but electric tankless units need very high amperage.
Should I turn off my water heater at night?
A timer helps if you have time-of-use rates. Otherwise the savings are small because a well-insulated tank loses little heat overnight.
