I am looking to buy a cab50 and was curious what the pellet usage is for this stove. The brochure says 5.8lb/hr and I was wondering if this is the max feed rate and would it be lower if the feed rate was lower. I am trying to compare the economics as I currently heat a 800sqft insulated woodshop with kerosene and wanted to know if it was better to go with a pellet stove. Any help would be greatly appreciated.
