Article needs work

This is fine as far as it goes. But for your average reader, we want to know how a given unit compares to other units on the market -- both current models and older models. This could be in a table, or a graph, or some examples. E.g., is .58-.62 relatively efficient for a new water-heater, compared to most others sold? Benefac (talk) 02:26, 16 July 2013 (UTC)[reply]

Uniform Energy Factor

The energy descriptor for water heaters is no longer Energy Factor (EF). It has been replaced with Uniform Energy Factor (UEF).^[1] There is much content on this page with relation to water heaters that is now obsolete. This raises a few questions in my mind. 1) Do we keep the existing page information on EF for water heaters for historical purposes? 2) Do we include information on UEF in this page or a new page?

A few of my own thoughts on question 1: the change is recent, so there is a need to include some content on this page to disambiguate the two metrics as they relate to water heaters. On question 2, the UEF covers a few new products that EF did not cover, i.e. residential-duty commercial water heaters. Due to the new scope, background of UEF, it might justify a new page. If any editors could point me to any relevant policies on the matter, or provide their opinions, that would be appreciated. Karma Heretic (talk) 17:22, 23 February 2018 (UTC)[reply]
