Thanks for the input!

I want to make it clear that this thread is not just for my questions, but for anyone who has a question about heaters ...... that way someone skulking the Forum without joining, and wanting answers to his/her questions will possibly be able to find an answer to their dilemma . Since we don't have a specific heading for heaters, this will help centralize the heater questions, just as we have centralized other questions such as pumps, etc.
