Heat for winter

[SuperiorF]

I have a Blueline Thermalwave How can I heat it for temporary freezes. What type of heat can I use that will not cause rust or burn things up? Can I use diesel heat? Any suggestions on a Bluetooth monitoring system? First year and I am terrified.

I use two small electric heaters, one in the back door and one up front on two different circuits. I don't have the blue tooth thing, just a remote temp sensor.

Probably runs that electric bill to high heaven
