HTP EVG-100******

This figure was computed by this site, not taken from the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, which is 0.93 for this model. It also uses the DOE test's daily hot-water draw for the high draw pattern. The result is 5,334 kWh of electricity a year. It applies only at that test draw, so a household with different use will see a different total. The source is DOE CCD, retrieved 2026-09-19. The class is the 21 models registered as an electric tank your utility can shift to off-peak hours. Their median at the high draw pattern is 5,392 kWh. This model is 58 kWh below that median, which puts it in the lowest quarter of its class for energy use.

The high draw pattern is a larger household, or one where showers and laundry overlap. The figure of 5,334 kWh was computed at that draw, so it fits that case. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 86 gallons. The rated volume is 96 gallons. The registry data does not show whether those gallons cover any one home's busiest hour. A household with a lower draw is outside the condition of this figure, and this page gives no figure for other draw patterns. To compare by fuel, space and size, use the water heater selector. To look for a unit in the same class, try the same-class replacement finder with a model number.

The running cost is not stated here because it depends on your own utility electricity tariff. Multiplying 5,334 kWh by your rate gives the yearly electricity cost at the test draw. The cost calculator on your own ZIP does this for you. The method is set out in how the annual cost is calculated. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it. The rank of 1st lowest of 21 concerns energy use only. It says nothing about price.
