Energy storage options explained

Thermal stores are highly insulated water tanks that can store heat as hot water for several hours. They usually serve two or more functions: Provide hot water, just like a hot water cylinder. Store heat from a solar thermal system or biomass boiler, for providing heating later in the day.; Act as a ''buffer'' for heat pumps to meet extra hot water demand.
