Filled: the three sets of A. O. Smith HPTV-xx 2; open circles: the other 98 heat-pump sets. Dashed lines mark 1× and 1.5× the rated volume; the highest ratio in the line is 1.13×, on A. O. Smith HPTV-80 2. Across the sizes From A. O. Smith HPTV-50 2 to A. O. Smith HPTV-80 2, rated volume grows by 36 gal and the first-hour rating by 41 gal: 1.14 gal of first-hour output for each added rated gallon.
The sizes test at different draw patterns (two high and one medium), so UEF and annual energy compare only between sizes that share a pattern (why ).
