About us in the USA

At Sunamp, we make and sell batteries that store heat and discharge it as energy that can be used for hot water, heating and cooling. By doing so, our products cut carbon emissions and help us all meet the challenge of achieving net zero by 2035.

We’re an ambitious company that’s growing fast around the world. We design and manufacture our thermal battery products at our headquarters near Edinburgh, in the UK and recently expanded our operations to include an office in New York.
