Is that chris?

tadaa, I would say 10-15 degrees, I am not sure exactly...I just know when I did it it took away my heat problems completley. Now your room cabinet set-up has a lot to do with it. forinstance I use AC...Now alone with transformer I still have to use fans, but without transformers, I can cut the ac and keep the room between 75-85 and all is good.

perhaps Zandor or Garden Knowm will chime in with their expertise.
