Excuse me guys, but I think I need a little clarification. Feel free to explain what I am missing ... But this is a heat "shield" that should be put around something to prevent radiant heat from reaching it. The maker seems to be quite clear (by using that term and not a more general word or listing others) that it is not intended to deal with conduction or convection, the primary culprits in "unintended" damaging heat transfers in our machines.
I am fairly certain that the heat from my electronics is not a threat to my boilers. I am not clear how much insulation by heat reflection in the opposite direction is provided by the unpolished foil glued to what I perceive to be a 1/16th layer of woven fiberglass laying against the copper boiler. It does disrupt the gaseous flow of the air (convection transfer), but how much more than the thicker looser fiberglass wrap is not immediately obvious. The extra boundary layer transfer introduces additional process inefficiency, but not a miraculous event. Bottom line: it would be nice to get 1. A measure of surface temperature of the foil after 45 minute warm up compared to surface temperature of the fiberglass wrap. 2. Ambient temperature in both types of machines, and 3. A two year follow up that provides some evidence of reduced brittle plastic and component failure in the machines that try it. But it looks really cool! Oh, and David, the UPC codes on the two items are identical.
