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 20 models with manufacturer data, full-load consumption runs 0.45–16.91 gal/h (median 11.69); at 50% load the median is 6.76 gal/h.
At 50% load, documented tank sizes give 0.4–68.4 hours (median 15.3 h) across 10 models.
