Would it be permissible to add pellets to the hopper of a pellet stove on Shabbat?
A pellet stove has a large pellet hopper that holds approximately 40 pounds of wood pellets. The pellet auger turns and carries a small number of pellets at a time up and drops them down into the burner, where a fire is kept burning constantly. Generally, 40 lbs of pellets will last 24 hours, but on particularly cold shabbosim, it may only last 18 or 20 hours. Is there any way that additional pellets could be added?
