Past few days I've been comparing the Heritage with the Vigilant in terms of how much fuel it goes through. My experiment is not perfect and neither is the accuracy. Reason for this is that I am awful at determining wood species, nor did I weigh the splits before inserting them into the stove. I've run this "experiment" three times. The vigilant was used as the time in which the reload was made. Reload time was determined by stove temp and ash bed. The experiment was not run consecutively as the Heritage would have gained an advantage as it had more coals and heating capacity upon reload.
Vigilant:
Fuel: 6 medium to large splits ranging from 20-23" in length
High temp of burn: 500 degrees all three times.
Temp in which the stove spent the majority of it's time: 450 degrees, 450 degrees, 475 degrees
Burn time: About 6 hours
Temperatures at reload: 300, 275, and just above 300 degrees
Heritage:
Fuel: 4 medium splits ranging in 17-19" in length
High temp of burn: 500, 500, 525 degrees
Temp in which the stove spent the majority of it's time: About 475 degrees all three times.
Burn time: About 6 hours
Temperatures at reload: 325, 325, 325 degrees (oddly consistent, but nice)
The Heritage is clearly using less fuel consistently. The second of the three times the Heritage had only 3 medium splits and what I would call a small split in addition due to the shape of the other splits. The high temps were intentionally limited to 500 degrees.
