United States
Two categories are open, water heaters and clothes washers: every model manufacturers have on file with the Department of Energy, not a shortlist. For a water heater, if yours just failed, start with the replacement lookup; if you are choosing, the selector narrows the list; if you have a model in mind, the calculator prices it on your own rate.

What a page carries
For a water heater, the yearly energy a model uses at the federal test's hot-water draw, where that sits in its class, and — once you give a ZIP — what it costs to run on your utility's filed rate. Heat pump water heaters are not a separate record type in the registry; they are a segment computed from the efficiency figure a model files, and every page that describes one says which threshold it used. Where the registry does not publish something — warranty terms, noise — the page says so rather than estimating it.
For a clothes washer, its filed efficiency rating and the yearly energy and water read back from it, where that sits among washers of the same product class, and what the registry does not publish about it.
The water heater methodology and the clothes washer methodology walk through the formulas, the tariff selection rule and where published costs disagree with each other.
