Finally, the resultant exhaust exiting the system was below 200F. https://images.squarespace-cdn.com/content/v1/694230f994bdba06bcb5f91b/c5fbd59d-1aeb-449a-acbc-5e0001c1ea47/Beer+brewing+over+GH.jpg Readings - Wet Dog Glass - Make it stand out This photo depicts a simple way to reclaim GH waste heat.

Hot exhaust flows upward through the straight inner pipe. Fresh air circulates around the inner pipe collecting heat as it flows through the outer chamber which is sealed from mixing with the exhaust gases that are essentially depleted of oxygen. The outermost surface is a thin stainless steel jacket that conceals the fiber insulation around the outer air chamber. https://images.squarespace-cdn.com/content/v1/694230f994bdba06bcb5f91b/9fa516b6-5182-4637-9bdf-9cb2d4d7c2a9/recuperator2.png Readings - Recuperation - Make it stand out This is an image digitally rendered by Correll Studios depicting a reheating chamber with a recuperator attached.
