Figures from each model’s own manufacturer documentation (spec sheets and manuals); runtime = documented tank capacity ÷ consumption at 50% load. Verify against the datasheet for your exact configuration.
Across 12 models with manufacturer data, full-load consumption runs 2.40–19.63 gal/h (median 10.92); at 50% load the median is 7.13 gal/h.
At 50% load, documented tank sizes give 9.1–153.8 hours (median 81.4 h) across 2 models.
