The Ice Cub is a residential thermal energy storage unit that integrates with your existing air conditioning system to store energy as ice during off-peak hours and cool your home during peak demand, when electricity is most expensive. It does not replace the condenser but works alongside it to reduce runtime and shift electrical load—delivering up to $1,200 in annual savings.
