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 13 models with manufacturer data, full-load consumption runs 0.45–12.42 gal/h (median 4.65); at 50% load the median is 2.56 gal/h.
At 50% load, documented tank sizes give 10.6–52.0 hours (median 25.3 h) across 3 models.
