US Stove MH6 Miracle Heat 6-Inch Heat Reclaimer. US Stove’s MH6 Heat Reclaimer has a quiet dependable fan that promotes heat circulation to improve overall efficiency. Every stove or furnace manufactured to date is not totally efficient. This means that heat which could be utilized is going up each and every chimney.

The heavy-gauge outer box and heat tubes also provide durability and long lasting performance. US Stove has been bringing warmth to homes across the nation for 140-year.
