Ya, I got the water pipe thing down pat, no cold air comin in from anywhere at all !!
my pipes ain't froze in 15 years I've been here since I bought this house anyway, as hot as I keep it,, usually Snow is melting off my roof faster than any of the neighbors .
1 year a few years ago after a 4in. snow, I was the only one in the neighborhood that didn't have any snow on their roof !!!
guess as soon as the snow would land on my roof, it melt I never paid any attention till a neighbor called me and wanted to know why I was the only one on my block that didn't have snow on their roof
I told them I constantly keep that Buck Stove constantly blowin hot air and pitchin wood and some trash in the thing, at that time I was maintaining a pretty constant 90* in my house on a 15*-20* night.
even my Garage was like 70* the heat was just radiating everywhere

:)
I've got plenty of insulation in the attic, I figured out with my Fireplace being Built in the "Middle" of my house, and NOT on some far wall,, with the Chimney going up thru the roof, which is tile lined - on the inside - the constant heat was also Radiating from the chimney,, heating the attic and working its way over to the garage.
Having a Fireplace built in the middle of the house with a Fireplace insert with a 2-Speed Blower makes all the difference in the world !!
Heats my the entire house 1800 sq. feet none of the other rooms are cold.
I have ceiling fans in every room, turn them on low to oscillate the heat, the house stays fairly constant thru out.
I used to live in Fort Lauderdale back in the late 1980's era, I know about those bugs and Croc's and Gators and rain & humidity , and tropical storms that blow thru
what I didn't know about was those "Sink Holes"

?? Yikes !!!!
alright gotta go, time for more wood on the Fire !
