What kind of thermometer are you using to measure the ambient temperature? I don't see how you're getting ambient air temperatures in the low 80's with surface temps at 70*F.
Well in many basements and even other floors the floor can be much colder than the air because heat rises. The enclosure could be on a stand or even on the floor and you could very well have colder surface temps than air temp. I could be wrong but this seems true in the basements I've lived in. Both wood burning and oil burning homes.
