Zero carbon industrial heat
Caldera’s electric Storage Boilers turn renewable electricity, whether on-site or grid supplied, into reliable industrial steam or hot water. By combining the features of an electric or electrode boiler with thermal storage, we help manufacturers electrify more affordably.

Electric boiler systems for industrial steam and hot water
Caldera’s ‘plug and play’ electric Storage Boiler provides process steam or hot water with integrated thermal storage, optional on-site solar, and intelligent controls. Our turnkey solutions offer a practical path to affordable decarbonisation—often without a grid upgrade:
Connecting to existing steam systems
Designed for durability
Straighforward integration
Blocked by slow, costly grid upgrades?
Our electric Storage Boilers can be charged at a steady average rate and yet still cover any spikes in steam demand, and with a flexible storage asset you can charge in off-peak periods to avoid the most expensive hours in the day.

GEA invests in Caldera
GEA reinforced its commitment to decarbonizing industrial heat by investing in Caldera in March 2025. This partnership brings together GEA’s global process and heating expertise with Caldera’s innovative electric Storage Boilers, enabling a holistic electrification solution for process heat. When combined with GEA’s heat pumps, the complementary system supports the decarbonization of industrial steam demand—typical in sectors such as food, beverage, and pharmaceuticals.
Learn moreTackling key challenges
Caldera’s Storage Boilers are a type of Electro Thermal Energy Storage (ETES) and effectively tackle a range of interconnected global issues.
Industrial emissions
20% of all greenhouse gas emissions come from making industrial heat.
Dependable heat
Electric boilers can’t deliver clean heat when renewables are scarce and expensive.
Economic viability
Current energy storage solutions do not match the cost-effectiveness of fossil fuels.
Grid congestion
Power from solar is very affordable, but grid congestion hinders rapid deployment.
