12 Stovepipe Heat Exchangers / 6 Dia. (19 cir) Set of twelve snap-on heat reclaim bands

Set of twelve 6-inch diameter stovepipe heat exchanger/radiator rings that reclaim heat from the hot stove pipe and radiate the heat into the room. They make close contact with your stack/pipe to draw more heat out of the pipe. They increase the area of heat dissipation. Heat is conducted into the radiator loops where the heat is transferred into the air. They work on the same principle as the aluminum heat-radiating fins on a motorcycle engine. The bands conduct heat from the points of contact on the pipe to the loops in the band where the heat is released. You get one set of 12 radiators. They are made of 28 gauge aluminum 1/12 inches wide. One set of 12 bands covers 18 linear inches of exposed pipe. They attach quickly and easily to your pipe or exhaust stack. No screws or tools needed. The ends lock into each other. It takes about 10 minutes to attach all twelve radiators. They will last a lifetime. They never need maintenance. You may put on as many bands as you have room for. Please measure your circumference with a flexible tape or string. (Circumference divided by 3.14 = diameter). See other listings for more sizes. (3 3.6 4 5 6 7 and 8 inches) (Other sizes available). Note the length of the pipe in the picture is not part of the sale.
