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 16 models with manufacturer data, full-load consumption runs 2.59–214.10 gal/h (median 5.15); at 50% load the median is 2.75 gal/h.
At 50% load, documented tank sizes give 14.2–63.7 hours (median 40.9 h) across 4 models.
