MF Fire creates fireplace inserts that feature three aspects: easy to use, efficient, and clean-burning. MF Fire believes that there's no reason a modern fireplace insert should be an inefficient hard-to-use piece of steel. That's why when MF Fire crafts a fireplace insert they expect it to last for the long haul, with seasonal and responsible use expect your MF Fire fireplace insert to be in your home for 10 - 20 years.
