Mickey I live in a basement of a private house in NYC, where this past week and next, temps are between 4 - 14 degrees, with temps at -5 to -15 with the windchill - so it is COLD!
The basement is ice cold in winter and sweltering in the summer.
I have one very large room where I have several stacks of 421D's piled 6 high, and then stacks of Blanket Box racks and stacks of Sweater box racks.
The bottom cages laying on the cold tile floor have double heat installed. The racks are on carpet tiles or styrofoam 2" thick.
They are stacked along the same, inside wall (other side of wall is basement of adjoining house) but not directly against the wall because along that wall runs the heat/radiator along the floor. This is hot water/pipe heat, not steam or air.
The cages are about 6 inches away from the heat source.
The cages alone throw off ALOT of heat which do alot of the heating for my apartment - my thermostat is set to 62, yes, 62! The boaphiles do the rest!!! lol
It is always 74-78 in my home, and usually in the cages, it is about 78-84 ambient temp, and 87-91 or so on the hot side... and my boas are almost always on the cool end.
I also very rarely turn the installed lights on, which throw off a bit more heat.
During the summer, I run the A/C 24/7 to keep the apartment cool. I set it to 72 and it's automatic with a timer.This keeps the ambient temps in the 'snake room' at about 76~ and my bedroom at about 72... I LOVE it COLD!!!
The temps in the cages almost NEVER change, and if they do, it is extremely minor.
My blanket box racks - the older models - could use a bit more heat...
and my sweater box racks - clear box model - give more than enough heat.
Overall, as I have stated many, many times... I am EXTREMELY happy with all my Boaphiles and will continue to order more and more!
I have moved out ALL other cages/tanks/enclosures INCLUDING all my Huge Vision Cages, which were a royal pain to deal with FOR ME.
I produced 2 litters this past season out of 2 breedings - both the females were kept in the bottom enclosures, where they, at the time, were laying directly on cold tile with single heat.
Can you believe that the gravid females were almost NEVER on the hot spots???
My 8 footer dropped 27 live, 2 stillborn, 2 slugs
My 9 footer dropped 37 live, 2 premies, 11 slugs
Because of the way they continued to eat and rarely used the heat while gravid, I wasn't sure they were gravid until the day they dropped !!! LOL !!!
Oh, and I only use Black.
Take care - guys
