Tub temps not getting hot enough with Herpstat 2 and Zoo-Med UTHs?

[SeSmith]

A CHE takes a long time to heat up and cool down. Make sure you use the proportional mode on the tstat.

Also aCHE calls for certain types of fixtures. Make sure you get the recommended style. Failing to do so will cause the CHE to burn up and you will waste your money. I have one going on 11 months of constant use.

I really would not suggest placing the fixture directly on the tub. I would find some way to suspend it our give it a stand off so it never touches any plastic.

Will do - will definitely use the T-stat on proportional mode as well, oh knowledgable one. What kind of fixture are you using? I was going to use a deep dome with a ceramic fixture? From reading around that's what a lot of people are using...?

EDIT: Or a wire cage clamp lamp I guess.
