Posted By: CWattersSeems to work for heatsinks in electronics.
Posted By: CWattersI think you should try to install them in pairs either side of the insulation so the thermal resistance between them is known. Would help settle the issue of how much power is flowing through the floor.
Posted By: Ed DaviesCWatters, as the multifoil discussion has already pointed out, knowing the temperature on each side of or even inside layers of insulation doesn't actually help much with knowing the rate of heat flow.
Posted By: Mike GeorgeThe point is though that it is the thermal resistance is what is questioned [at least in the case of multifoil] Using the hot box derived value does little to settle the argument..
In the case of floors, the P/A method of calculating u-values based on 'known' steady state conductivities is also questioned by some .
Once again using the said conductivities [of say PUR] as a basis for calculating energy use is not going to establish whether it is better to put the PUR in or not.
