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 0.40–10.94 gal/h (median 10.22); at 50% load the median is 5.42 gal/h.
