It's a true & bit of a bummer fact: most homes are incredibly energy inefficient. Especially when it comes to heating. But people must change & figure out how to do it. (hint: 50 cent per watt solar and cheaper.. you just may be able to heat with solar. storing energy as heat... you don't need a battery. You need concrete.) Evolve or die. BTW, lithium batteries do not off gas hydrogen (like lead acid batteries do). Therefore, you just keep your batteries inside with you. They'll work just as efficiently and any of their 5% inefficiency will become heat.
