    The sole remaining factor is heating in winter. Which can not be solved by better battery storage

    My parents house used to have thermal storage heating which seemed to work well. Each room had what looked like a standard sized radiator that stored heat, much more cheaply than a battery: nothing toxic, nothing expendable, nothing expensive. Overnight when rates were low, the unit heated up. During the day when rates were high, we just needed a small circulation fan to keep room temperature consistent with almost no power use.

    I just had to get a new heat pump installed and looked for similar functionality but it doesn’t seem to exist.

    Thermal storage heat would make a huge difference in shifting power usage from heating to account for factors like solar energy, and it would be much cheaper than batteries.
