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.
Why use a Thermino thermal battery for hot water?
No mandatory maintenance
The Thermino range
The Thermino range – our fourth-generation heat store for hot water – maximises the use of renewable energy and can be charged by air-source heat pumps, ground-source heat pumps, photovoltaics (PV), grid electricity and boilers.
These thermal batteries are designed for retrofitting to existing hot water systems or specifying for use in new build projects. Their sleek, super-compact design means they look good in any home and free-up valuable storage space.
