[RE-wrenches] aluminum heat fins for radiant retrofit...who's got 'em?

[Darryl Thayer]

I have used this approach with 1/2 inch nom. copper tube, it works.  The Aluminum I got form New Jersey Aluminum, they sold out to another company.  I am not sure it is made any more, but I had a custom extrusion made for me for about $3000  I have also seen a thin folded AL fin from floor heat people.  Study your floor heating manuals well for sizing.

Hello, Wrenches~
Please see the photo on page 48 of the latest Home Power magazine (#138). This shows aluminum fins with an extruded clip into which Rehau type radiant floor tubing can be clipped. 


Where can I get these parts for resale?
Have any of you observed an installation where this approach actually worked OK? I'm sure the aluminum  fin would extract heat from the tubing OK but the wood subfloor won't extract heat from the aluminum very quickly. Insulation between the aluminum fin and the air below it might help, right?


My client wants to retrofit solar heat to an existing home which does not have the in-floor radiant tubing embedded in lightweight concrete--the more common way to do a radiant floor. He had planned to drive existing baseboard radiators but the higher temperature which those require (compared to a radiant floor) led to this pursuit.


Thanks in advance,
