The Lancey electric space heater allows users to charge its battery during off-peak hours and use the electricity for heating during peak demand periods. A French startup is approaching home energy storage from a bit different of an angle, and instead of merely functioning as a home battery, its product doubles as a radiator that is said to be able to help reduce heating costs by as much as 50%. The radiator from Lancey Energy Storage is described as a plug-and-play space heater, which means that even though it integrates a lithium battery and can allow users to charge it during times of cheaper electricity, and then use that electricity when grid prices are higher, no additional wiring is necessary to install it, and it can cost up to 75% less than installing a gas heater. And since heating can account for a significant percentage of home energy use this represents a great opportunity for both homeowners and rental property owners alike to reduce costs and environmental impact.
