Sunamp

Who we are

Sunamp is a pioneer of innovative thermal storage solutions. Founded in 2005, our mission is to transform how we generate, store and use heat to make a significant global impact on tackling climate change and safeguarding our planet for future generations.

Global warming, energy security and fuel poverty are issues that can be addressed by increasing renewable energy and cutting out ‘burn on demand’ fossil energy. Sunamp’s world-leading thermal storage technologies work with a wide choice of energy sources to help to deliver highly effective, low-carbon heating and cooling in buildings.

We have a holistic approach to sustainability that permeates our staff culture and affects everything we do as a business. We have signed up to the SME Climate Hub commitment to halve our greenhouse gases by 2030 and achieve net zero emissions before 2050. As a result, we are committed to playing our part in achieving a climate-resilient, net-zero future.

What we do

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.
