I read a lot about people using oil filled heater to heat the ambient in the room and have it controlled by a thermostat. I remember a couple years ago or so, the electronics store here REFUSED to sell me a thermostat when I told them I was going to hook it up to an oil filled heater. They said it was very dangerous to do so, I don't know why.

But let me start by knowing what to tape down the flex watt first. I have another issue. I know it is done a lot of people using foil tape to affix the flexwatt along the sides, but not to tape ACROSS it running across both AC metal strips. However, I have the flexwatt 11 inch so that the tubs will slide ALONG it, (i.e., the horizontal black heating elements are paralell to the back of the tub), so I need to tape the part across it where the tub will slide on. This will be across the two AC current lines. What can I use??
