The Mansfield is a workhorse of a stove. It can provide up to 14 hours of sustained heat on a single load of wood. Producing up to 80,000 BTUs, it can tackle the coldest of climates and keep your entire home warm and comfortable, even when you’re out enjoying the snow all day long, or are too pooped to get out of bed and put a fresh log on the fire in the middle of the night.
