I'd like to use my rectangular 70 qt cooler as a base for an eHLT.
Here's what I'm thinking... two 1500w elements placed horizontally through the back of the cooler, each fed by it's own power source (The biggest circuit I have in my apartment is 25 amps, and I think that load might be pushing it for that). Both units switched by SSRs and then either a PID or a simple Temp controller like the Love.
Now for the questions, Is it possible to control both heating elements with one controller? And how much space should there be between the elements and the bottom of the cooler?
