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 10 models with manufacturer data, full-load consumption runs 0.40–27.10 gal/h (median 7.40); at 50% load the median is 3.80 gal/h.
At 50% load, documented tank sizes give 14.1–39.4 hours (median 18.2 h) across 4 models.
