Thanks folks, I appreciate the info. @mikeref, you're not kidding…*I checked the internal temp and it was way too warm! Turned that puppy right back on

@spimps, remember I need to keep the door closed or else we'll attract rodents, so it'll just have to be left on all winter. Just trying to save a little energy where possible, but clearly this isn't one of those places!

thanks again,
