Dual fuel electricity rates are significantly lower than standard rates. There are devices made in Russia that are specifically sold as Bitcoin mining space heaters. Is it permitted to use a crypto currency miner for heating and thus qualify for the lower energy rates?
Is it permitted
There are certain regions (e.g. the Pacific Ocean) where everything is permitted, and certain regions where doing stuff that are allowed by law may even land you in jail.

Yes, this is a smart thing to do wherever it's cold and mining is permitted!
Be careful, if mining is illegal, your ISP or your energy supplier may figure out that you're mining.
