Caldera Heat Batteries Ltd

Company Profile

Caldera’s pioneering thermal storage boiler is enabling many companies to make significant steps forward in their decarbonisation plans.
Caldera’s system is ideal for providing process heat in the temperature range of 100 up to 210°C. By combining their Storage Boiler with Solar PV or off-peak grid power, Caldera transforms renewable electricity into affordable, on-demand zero-carbon heat, effectively displacing reliance on fossil fuels.
At its heart is a long-lasting core of volcanic rock and recycled aluminium which stores high temperature heat and can charge or discharge rapidly. This cutting-edge material not only meets stringent environmental standards, but also offers industry a reliable, cost-effective alternative to traditional heating methods.
