Upgrade your hot water system with a space-saving, super-efficient Thermino heat battery. The systems are up to four times smaller than a conventional hot water cylinder because they’re filled with our patented energy-dense phase change material, Plentigrade.

Thermino batteries have much lower heat losses than a cylinder and work with a range of energy sources, including heat pumps. They’re future-proofed for solar PV thanks to Optimino technology, which allows you to move to renewables seamlessly in stages.

Join thousands of households who have already switched to our award-winning Thermino for reliable, mains-pressure hot water, powered by low-carbon energy.
