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 0.63–5.34 gal/h (median 3.78); at 50% load the median is 2.31 gal/h.
At 50% load, documented tank sizes give 6.6–236.1 hours (median 21.2 h) across 5 models.
