These high thermal conductivity aluminum bands may be added to stove pipes, exhaust stacks, or other pipes and tubes to extract heat from the pipe and radiate the heat into the air. Heat is conducted into the band loops where it exchanges with the air.
Made of highly conductive 28 gauge aluminum 1 ½ inches wide.
Our heat exchangers are sold in sets of 6.
All standard American stove pipe sizes are available: 3", 3.6", 4", 5", 6", 7", and 8" diameter.
Bear in mind that these are the diameters of the pipes, but to measure your pipe, you will have to measure the circumference (the distance around). Please see our detailed instructions.
Sizes for smaller pipes are also available:
3½", 4¼", 5", 6", 7¼", 7¾", 8", and 11¼" circumference.
Please be sure to measure your pipe before ordering.
We can also supply custom sizes. Email us.
These heat exchangers are designed to be installed onto existing hot pipes to extract heat from the pipe. The pipe conducts heat into the aluminum heat exchangers and radiates the heat into the air. (Inversely, they may also be used to warm cold pipes.)
They work on the same principle as fins on a motorcycle engine. They conduct heat into a larger square area of exposed surface to allow more heat radiation. The bands make tight contact with your pipe and conduct the heat into the loops where convection through the loops allows more heat to be given off.
The bands conduct heat from the points of contact on the stovepipe to the loops in the band where the heat is released into the room. The band loops get as hot as the stovepipe...too hot to touch.
So for example, by installing a set of six 6 inch diameter bands, you create the equivalent of this 12 in. x 15 in. sheet of hot sheet metal, 500 - 700 degrees, radiating heat from both sides of the sheet into the room before it escapes out the chimney. That is like a small space heater itself...and it is FREE HEAT.
They attach quickly and easily to your pipe....no screws or tools needed. The ends lock into each other. It takes less than 5 minutes to attach all six heat exchangers.
CAUTION: WEAR GLOVES and SAFETY GLASSES during installation! Install when the pipe is cool.
