Caldera is a heat battery company that seeks to institutionalise zero-carbon energy solutions for the masses. It asserts that its 'Zero Carbon Boiler' is a direct replacement to an oil or gas boiler by providing low-cost renewable electricity as heat for later use on demand by the homeowner. The company asserts that the boiler consists of two elements. The first is Caldera's proprietary 'Warmstone Heat Battery' that can be charged by low-cost electricity from the grid, store that electricity for 24 hours and provide it on demand. The second is a 'Heat Interface Unit' (HIU) that replaces the existing boiler. Caldera believes that low electricity prices always tend to occur when the source of electricity is also low carbon. It will use the investment to grow its business across different verticals.
