comment Measuring temperatures at two points: weird trend?
Hmm, just one last question about this CoP. Why is that the CoP is greater than 1 in the case of cooling?

comment Measuring temperatures at two points: weird trend?
Hi mdma: The freezer is always switched on, it is never turned off. Also, I'm using a 120W heater instead, so the heating/cooling difference is not that large I think. If I go with the idea of thermal inertia, why is that the lower sensor (Sensor #1) changes so quickly then? Shouldn't it face the same problem?

Here is the trend with no heater and the freezer merely cooling: i47.tinypic.com/2430vp2.png , I couldn't post it in the original post since I do not have sufficient rep points. The heater pad type, I am using is this: winemakersdepot.com/Brewers-and-Wine-Making-Heat-Pad-P700.aspx
