Filled: the four sets of Rheem PROPHxx T0 RH120-M; open circles: the other 97 heat-pump sets. Dashed lines mark 1× and 1.5× the rated volume; the highest ratio in the line is 1.25×, on Rheem PROPH40 T0 RH120-M.

Across the sizes

From Rheem PROPH40 T0 RH120-M to Rheem PROPH80 T0 RH120-M, rated volume grows by 36 gal and the first-hour rating by 39 gal: 1.08 gal of first-hour output for each added rated gallon.

The sizes test at different draw patterns (one high, one low and two medium), so UEF and annual energy compare only between sizes that share a pattern (why).
