The easy, affordable way to electrify industrial steam
Cut gas use, stabilise energy costs and avoid a grid upgrade.
Electrification doesn’t have to mean higher bills
Whether your goal is a positive ROI or the lowest-cost path to full electrification, the right system design makes all the difference. Caldera can model your steam demand and find the best payback, including hybrid systems alongside gas boilers or heat pumps.
Storage Boilers can often achieve a positive payback by charging off-peak, earning revenues from balancing the grid, maximising use of an existing grid connection and minimising thermal losses.

Electric boiler systems for industrial steam
Caldera’s Storage Boiler is an electric boiler with integrated thermal storage and intelligent controls. At the heart of the system is Caldera’s proprietary technology, combining advanced storage materials with vacuum insulation to deliver high efficiency and minimise heat losses.
Designed for rapid installation and easy integration into existing steam systems, our turnkey solutions offer a practical path to affordable industrial steam decarbonisation.
Applications across sectors
Industrial sites can electrify steam without replacing the equipment their process already relies on. Caldera’s Storage Boilers suit any steam-using sector, including food and beverage, brewing, distilling, pharmaceuticals, chemicals, and paper and packaging.
Generates steam up to 16 barg (204°C)
Enables full or partial electrification
Fits retrofit or new build projects
