[Greenbuilding] Advice on heating in Tucson

[Racheli Gai]

I agree that a small heating device is probably all that we need. --
any recommendation for a particular one?
Also, since it might be used sometimes when there are small children 
around,
are there any such gizmos which don't get too hot to the touch?

Racheli.
