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 17 models with manufacturer data, full-load consumption runs 2.62–65.20 gal/h (median 51.51); at 50% load the median is 26.68 gal/h.
At 50% load, documented tank sizes give 2.2–63.2 hours (median 25.3 h) across 10 models.
