I'm not speaking from experience but if you're not nice to the shed I doubt it's going to make this easy for you.

What I would do is maybe add some insulation?

I know I've seen people plumb their chillers outside successfully. A lot depends on how cold it gets there. Perhaps have the shed built right up against the exterior wall like an addition? Maybe building code plays a part in doing this properly as well?
