Verdict in brief
The EFTC-199W is the larger EFT Combi Wall: it fires 19,900-199,000 BTU/hr for DHW (against the 140W's 28,000-140,000), delivers 9.9 vs 7.1 GPM at a 35 °F rise, and uses the deeper 19.7 x 37 x 16.8 in cabinet at 120 lb. The 140W prints a slightly lower 95.0% AFUE against 95.1% and runs at a 5:1 turndown versus the 199's 10:1.
