We had Top Hat install a Jotul wood stove insert and chimney back in 2006. They were very professional and did a great job. We've had no problems and use the stove as our primary source of heat. It's been a great investment and the staff were very helpful in providing recommendations on the type of unit we needed to heat our home. We burn about 3 full cords of wood a year in it and have absolutely zero complaints. Would definitely purchase through them again.
