I'm stupid when it comes to electronics, but I can at least follow directions. I'm buying a PID controller to build a HERMS system, and I see that most of them come with contacts for a regular relay and a SSR. Does anyone know what the difference is between the two, and which I would want to use to power my heating element (probably will be a 120 volt water heater element) for my heat exchanger?
I have a friend who's very good at this stuff, but I wanted to do it on my own (as far as he knows). Although I could sure enlist his help - he drinks enough of my beer.
