I was working in my sump today and got the ---- shocked out of me. Electricity was getting into the water. I finally traced it down to a faulty pro-heat titanium heater (2years old so out of warranty) question is, shouldnt these heaters have a built in safety device to shut them down? I just ordered three more of these ( which have been backordered for over a month ), now Im not so sure I even want them. I use a medussa controller so all I really need are heaters that wont try to float, does MD offer heaters with no temp controls?
