I have heard that as well, but don't they have a water line on them?

Best heater was the Ebo Jager before they were bought out. I have one that has worked perfectly for the last 12 years.

the water lines are on submersible heaters so that they can pass CSA standards......if it is labeled as a submersible heater then it can be fully submersed, despite the water line mark
