Thousands of Sunamp thermal batteries are already in homes across the UK storing heat from low-carbon energy sources and releasing it for mains-pressure hot water when needed.
Our Thermino batteries replace traditional hot water cylinders – direct (for grid electricity and solar PV) or indirect (for boilers and heat pumps).
They are up to four times smaller than the equivalent hot water tank because they are filled with our energy-dense phase change material, Plentigrade P58. This means that heat pump systems can be installed where otherwise they wouldn’t fit, for example.
