So what is a contraflow fireplace? Who knows how to build one? Not me as of yet. The idea sounds interesting, though. With a huge pile of bricks in my front yard, I started my research.
Turns out the idea, although it carries a very long and distinguished history, dovetails neatly with today’s green revolution. The northern European countries and Russia have been using masonry stoves for years since the 17th and 18th centuries, when kings in Prussia and Scandinavia ordered their craftsman and architects to produce better wood stove designs.
