    If you watch the video, you’ll understand that the temperature transfer process to a hot water tank is incredibly slow. So, water tanks are not a very good battery.

    I mean, unless you want to spend 12 hours trying to dry your clothes.

      Also you can pull heat out much faster when needed. If there’s heat left when you’re done you can feed it back with a heat exchanger
