Results for horizontal orientation
Heres a copy of the results for the vertical orientation
From the results of the tests. The vertical orientation seem to yield better results in terms of consistency. This is prob due to air moving in and out of the house, even if it is minimal. The using the rad in horizontal orientation to "move" air by heating it doesn't seem to provide any obvious benefits(prob due to tight spacing of the rad). Will dig out my 120mm fans to fix on the rad for another set of results(prob in 2 days?).

Disclaimer: Results are based on one test each, and most prob not conclusive. Getting results over a longer period will prob provide even more data. But i'm getting lazy
