What is the Portage & Main Outdoor Water Furnace?
Portage & Main Outdoor Water Furnaces are designed to look like an attractive storage building and installed outside the building to be heated. The water jacket surrounds the furnace firebox and the heat is transferred from the wood fire to the water. It is a safe and efficient way to heat your building with wood. They are called water furnaces because they circulate hot water to provide heating needs. They have been referred to as outside wood furnaces because they are outside and burn wood.
