I bought my oil filled radiator heater at Lowes a couple years ago. I think the brand is Pelosi. It has as a built in thermostat. I run the heater on a Ranco thermostat, which is set to 80f and I have the built in thermostat set to about 90f as a back-up. If you choose to use an external thermostat, I recommend either a Ranco or Johnsons, because they can handle the wattage draw of the heater. I also recommend either ordering it pre-wired for a heater or doing it yourself, using a heavy duty extension cord.
