When to use tank heaters?

New Cardinal owner here and dealer not very knowledgeable. Do I need to have water in the tank a before using tank heaters? If stored for the winter should I use the tank heaters to keep underbelly warm? We don't have extreme temps here, gets down to 28-30 a few times in the winter. Thanks

Your tank heater is a square patch on the exterior of the tank(s). And yes you should have some water/liquid in them to use. Additionally, you should have wrapping (a small strip of heat tape) around the pipe(s) leading or next to the dump valve(s). I have used mine for every winter (7 yrs.) and have left the switch on with no damage. This switch turns on all installed heater patch(s) for your tanks and drains.

You only use the tank heaters when there is water in the holding tanks, otherwise, with no water in the tanks, there is no need for heat. Nothing in them to freeze.

The tank heaters do not keep the underbelly warm. They are simply heating pads that stick to the tank(s) and apply heat to the tank(s) and their contents through conductivity.

If it's stored for the winter why would you want to heat the tanks. Hopefully you emptied them prior to storing. If there is some residual liquid in there it likely won't freeze given the low temps you quoted. And if it did drop cold enough to freeze them it's still not an issue since there is plenty of room for expansion. Water in those tanks is not at all like water in a supply line.
