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 5 models with manufacturer data, full-load consumption runs 2.62–317.00 gal/h (median 128.39); at 50% load the median is 19.28 gal/h.
At 50% load, documented tank sizes give 25.7–25.7 hours (median 25.7 h) across 1 models.
