VAUGHN ME30

0.92 UEF DOE CCD · 2026-09-19
G

Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, low draw pattern (a one- or two-person household).

Checking the VAUGHN ME30? It uses 2,439 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against, for a small household. That is 0 kWh from the class median of 2,439 kWh across 163 electric tank models. It ranks 19th lowest in energy use.


Energy use per year

2,439 kWh a year

Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.

That is equal to the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 19 of 163, lowest energy first.

This model: 2,439 kWh

What these figures mean

The figure of 2,439 kWh is computed by this site, not the registry. It combines the registry's UEF of 0.92 with the daily hot-water draw the DOE test uses for the low draw pattern. UEF, the ratio of hot water delivered to energy used, is the efficiency value behind the calculation. The figure covers electricity only and applies at that test draw, so it is not a measurement of any particular home. The source is DOE CCD, retrieved 2026-09-19. Against the class median of 2,439 kWh, the difference is 0 kWh. The model ranks 19th lowest of 163 for energy use, which places it in the lowest quarter of its class.

This model matches a household that fits the low draw pattern, because that is the draw behind 2,439 kWh. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 42 gallons, and its rated volume is 29 gallons. This page has no energy figure for higher draw patterns, so it cannot say how the unit would use energy in a larger household. For that case, the water heater selector by fuel, space and size narrows the options. Households with different hot-water habits should treat 2,439 kWh as a reference point at the test draw only.

Running cost is not stated in this text because it depends on your own utility electricity tariff. The annual figure of 2,439 kWh is the quantity your rate multiplies. The class median of 2,439 kWh is multiplied the same way, so the difference of 0 kWh implies no cost gap at any rate. To see a cost for this model, use the cost calculator on your own ZIP. The steps behind it are set out in how the annual cost is calculated. The modeled installed-cost range appears in its own block on the page with its source and date, and it is not repeated here.
