How this is calculated
- Annual energy use is the figure ENERGY STAR lists for this model under typical test conditions. It is not measured in your home.
- Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
- Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
- We do not estimate watts or hourly cost: the source data does not include them.

Frequently asked questions
How much electricity does the Ruud CPROPH65 T2 CD375-30 use?
ENERGY STAR lists 1213 kWh per year under typical test conditions, as ENERGY STAR publishes it for the usage pattern of the rating. Your use will differ with household size, how much hot water you draw and the temperature of the room the heater sits in.
How much does it cost to run?
At statewide average residential prices, the listed annual use costs about $154.29 in Louisiana and $582.24 in Hawaii (EIA, 2026-07). Your own utility rate may be different; enter it in the calculator.
How does the Ruud CPROPH65 T2 CD375-30 compare with similar models?
Among 376 ENERGY STAR certified 240 volt integrated HPWH models with a similar tank size, it ranks 248th lowest in annual energy use. Its 1213 kWh per year is 28% above the median of 944 kWh.
What does the uniform energy factor mean?
It is the hot water delivered for each unit of energy the water heater uses, so a higher number means lower running cost. This model is listed at 4.05. A heat pump water heater scores far above a conventional electric one because it moves heat instead of making it.
