In other news, a minor was just charged with viewing elicit images of a minor in his bathroom mirror!

Wouldn't a simple DC/AC converter for your car work? Then run an extension cable indoors. Cut the line to the furnace and connect the line to the extension chord...instant power to your blower. Once the house is warm, connect the extension cable to the fridge....then to the deep freeze...It might be a bit of a pain, but only costs $50.
