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 0.21–1.00 gal/h (median 0.58); at 50% load the median is 0.37 gal/h.
At 50% load, documented tank sizes give 11.2–11.2 hours (median 11.2 h) across 1 models.
