Best outdoor heat?

[CharlieM]

What is the best way to heat this outdoor enclosure? I will fully or partially cover the wire with plexiglass. I am in South FL so most winter days are 75 degrees plus. Nights can occasionally be 40s or 50s.
What is weather and waterproof? Heat ropes, pig blanket or CHE?

Rather than try to heat the whole thing, I would build a doghouse type of thing and attach it to the enclosure, then you can just heat the doghouse with a heat mat or a CHE on a thermostat. Make it with a door, so you can lock them in on cold nights, and then just ow the door during the day.

Ok thanks. Redstrike has also suggested using a CHE with a thermostat. That's what I'll do. I can also bring them inside if needed.
