Member - Sunamp Ltd

We develop, make and sell thermal batteries that store energy using our patented phase change materials and discharge it as heat that can be used for hot water, heating and cooling. Sunamp thermal storage is up to ten times more energy dense, and occupies between 65% and 90% less space, than conventional systems such as hot water cylinders. Our thermal batteries charge from renewable energy sources such as air-source heat pumps, ground-source heat pumps and photovoltaics (PV), as well as electricity from the grid. This means our customers can make better use of renewables and in turn, benefit from improved energy efficiency and lower carbon emissions. We design and manufacture our thermal battery products at our global headquarters near Edinburgh in the United Kingdom. Here, we have our factory, research and development labs and customer training centre. Thousands of Sunamp heat batteries are already replacing traditional hot water cylinders in homes and enabling housing organisations to safely remove gas from buildings. We are an ambitious, imaginative business that’s growing fast. Recent expansion includes offices in New York and Zurich.
