This is a set of six custom size boiler pipe heat reclaimer / radiator rings that extract heat from hot boiler pipe and radiate the heat into the room.  

Custom size, typically made to fit 1 7/8" diameter to 2 7/8" diameter.... 5 7/8" to 9" circumference

Contact me with your circumference measurement upon ordering.

Installed, they make close contact with your boiler pipe and conduct more usable heat from the hot pipe to be released into the room.  They, in effect, increase the surface area of your  boiler pipe therefore allowing more heat to be radiated and released into the room.  They work just like the fins on a motorcycle engine, they increase the area of heat dissipation.

You get one lot of 6 custom radiators.   They are made of 28 gauge high thermal conductivity aluminum,  1  ½" wide.  

Installed close together, this one set of 6 radiators will cover 9 inches of pipe.

They attach quickly and easily to your boiler pipe....no screws or tools needed.  The ends lock into each other.  It takes about 2 minutes to attach all six radiators.  The bands conduct heat from the points of contact on the boiler pipe to the loops in the band where the heat is released into the room.  The band loops get nearly as hot as the boiler pipe. 

PLEASE,  PLEASE......MEASURE THE CIRCUMFERENCE OF YOUR PIPE (the length around) WITH A FLEXIBLE TAPE MEASURE !     Do not guess at your diameter...it is impossible to measure the diameter of an installed pipe.    ORDER BY CIRCUMFERENCE...NOT DIAMETER.

Contact me with your circumference measurement upon ordering.

Also, see my other listing for larger size  stovepipe radiators for 3", 4", 5", 6", 7", and 8" dia. standard pipe.

These have larger loops than the boiler pipe radiators.

They will last a lifetime.  They never need maintenance.  

They are guaranteed to draw more heat from the boiler pipe.

They pay for themselves in a short period of time.

 You may put on as many bands as you wish or have room for.  The more bands, the less heat going out the chimney.
