I have read a lot of threads on using oil filled space heaters to heat outdoor hides for tortoises. I need to keep my hermann's awake for at least part of this winter. I have built an enclosure that is 2 feet by 6 feet by 2 feet tall. I have insulated with foam insulation but am finding it hard to maintain temps with 150 watt CHE. I was toying with the idea of using the optimus 6003 which is a 700 watt oil filled heater. I am just afraid of burning the place down. I have read so many warnings with oil filled space heaters in homes. Has anyone used these indoors for their enclosures? I was going to place this heater on it's own breaker since the breaker box is very close to the enclosure and run romex to a designated outlet. I will also use a proper thermostat rated for the wattage. I would like to place on the floor of the enclosure and place a wood barrier around it to prevent the tortoises from coming in contact with it. Does this sound safe? I know @Tom does this with his outdoor heated hides. Again I just don't want to burn down my house! Any suggestions would be appreciated.
