The actual heating unit is also replaceable if it dies. My smaller tank heater is less fancy. It has a controller, but no external probe. It does still have some kind of sensor that kicks the heater on if the temp falls below what is set on the dial. For reference, the big heater was around $48 and the small one was around $32. Not sure if that makes them a good deal or expensive. Your doing great! 1 Link to comment Share on other sites More sharing options...
