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 7 models with manufacturer data, full-load consumption runs 4.70–90.35 gal/h (median 90.35); at 50% load the median is 0.69 gal/h.
