Don't RTGs generate power constantly? That would make them impossible to use for a casual customer.

1) Sell the power back to the power company (granted, at the wholesale price)

2) Use the heat given off to generate more power

Such a convenient space heater wouldn't ya know?

Possibly. I'm not sure what you would do with it in the summer though. Even Arctic and Antarctica have pretty big seasonal temperature variations.
