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 25 models with manufacturer data, full-load consumption runs 1.20–77.90 gal/h (median 62.87); at 50% load the median is 31.70 gal/h.
At 50% load, documented tank sizes give 2.2–1601.5 hours (median 30.9 h) across 10 models.
