Heaters

[tmcmaster]

Waterbed heaters are designed to lay flat under the bed. The ones I had way back did not attach in any way, so you would need to find a way to attach it. There might be simpler solutions then going with a waterbed heater.4

I was honestly thinking duct tape or hot glue on the outside of the tank. I found one at a cheap price on EBay, so once I get it, and test it, I can post results.
