> a typical baseboard heater is 1k If you're talking big, expensive batteries, you may as well include heat pump heating/cooling systems, which are much, much, much more efficient than traditional electric heaters, and can be rigged up with shared infrastructure to reduce costs. For example, my building has one large hot/cold water loop that individual units hook into with small heat pump systems.
