Friedrich PROHxx T2 FD310BM

The Friedrich PROHxx T2 FD310BM line holds four certified rating sets of 240 V integrated heat-pump water heaters, 48 model numbers sold under three brand names, listed by Rheem Sales Company. Rated volume runs from 36 to 72 gal, and the first-hour rating runs from 60 to 87 gal. UEFs compare only within a draw pattern; the two high-draw sets rate UEF 3.50. Friedrich PROH65 T2 FD310BM lists 900 kWh/yr, the lowest of the 58 high-draw heat-pump sets. Friedrich PROH40 T2 FD310BM lists 1.67 gal of first-hour output per rated gallon, the fourth highest of the 101 heat-pump sets (shared by two sets).

Filled: the four sets of Friedrich PROHxx T2 FD310BM; 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 1.67×, on Friedrich PROH40 T2 FD310BM.

Across the sizes

From Friedrich PROH40 T2 FD310BM to Friedrich PROH80 T2 FD310BM, rated volume grows by 36 gal and the first-hour rating by 27 gal: 0.75 gal of first-hour output for each added rated gallon.

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