Should I get a second UTH???

Thank you for the tips.

I have one more question what do you insulate the tub with?

In the winter I insulate the front of my tubs with this aluminum covered foam that is used to insulate Hot/Cool ducts. I found it in the heating and cooling section of home depot. I'm sure its not the prettiest solution but it worked for me on helping me get those extra couple degrees on the cool side. I have my tubs in a rack system though so there is only one exposed side that I had to insulate.
