Apologies, from looking through past posts I see this comes up a lot. Unfortunately I'm completely inept when it comes to electronics.

I'm not going to be getting my BP until spring, but I'd like to pick up my Herpstat while they're currently having their sale. The problem is, I'm having a hard time figuring out if I should get the 1 or the 2. It gets very chilly here in Iowa, so in addition to regulating my heat tape I'm most likely going to need a heater for the ambient temps as well. Would the Herpstat 1 be able to handle both the heat tape and a CRH or do I need to get the Herpstat 2 for that?
