fish room in a shed outside?

[Mrfish55]

I have plumbing that goes outside into a small shed that houses the chiller, never had a problem in the winter but I am starting to have overheating issues now that summer is here, the shed traps and transfers too much heat (even when left open to vent the chiller), kind of defeats the point behind the chiller, I am dealing with close to 1000 gals on the system, I think a smaller system would see even greater temperature swings. I know Lance has the sump for his corner tank outside in an insulated box and has not had a problem but it is well insulated and right against the house.
