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 31 models with manufacturer data, full-load consumption runs 0.54–59.70 gal/h (median 10.04); at 50% load the median is 5.60 gal/h.
At 50% load, documented tank sizes give 0.2–213.7 hours (median 45.2 h) across 11 models.
