Using PTC heaters to Store Electricity as Heat #
Looking for a low-cost way to store solar-generated electricity as heat? Consider using PTC heaters to transfer energy from solar PV panels into brick, sand, or other thermal storage materials. PTC stands for Positive Temperature Coefficient. PTC heaters are made from ceramic materials. Compared to traditional elements that use wires or coils to generate heat, PTC heaters are safer and more energy efficient. Stored thermal energy can heat a home, greenhouse, or household water without the need to store electricity in expensive batteries.
For example, you might use PTCs to heat a residential-sized steel slag or sand battery.
