Energy-saving compact thermal storage
Sunamp heat batteries can be charged with large amounts of energy from renewable and other sources, and released to deliver hot water, cooling and space heating on demand across a wide range of temperatures, and for a wide range of residential and industrial applications.
The company’s range of heat batteries for the residential market provide a low carbon, reliable, space-saving alternative to traditional hot water cylinders, safely cutting energy consumption and fuel costs.

Residential
Sunamp heat batteries are energy-saving thermal stores that efficiently store heat for hot water on demand. Up to 4x more compact than traditional hot water cylinders and with far lower heat losses, they are easy to install and compatible with a wide choice of energy sources including heat pumps, solar PV and boilers.

Commercial & Industrial
From dairy farms to distilleries, airports to hotels, commercial and industrial heating and cooling is more cost and energy-efficient with Sunamp thermal stores. Modular and scalable, they are also ideal for off-grid use, maximising efficiencies from renewable energy sources. Large scale static and transportable energy storage is suitable for waste heat capture.

Automotive
Our thermal storage technology will revolutionise the automotive industry, with heat and cold batteries that reduce emissions, improve air quality and fuel efficiency in hybrid and conventional vehicles, and address vehicle thermal management challenges like engine and cabin warm-up. Most vehicle types can benefit.

Cold chain storage
Our cordless cold box, Permafrost VacSafe, stores Covid-19 vaccines safely at ultra-low temperatures (-70C) for weeks, preventing waste. Small enough to be stored on-site in care homes, surgeries and out in the field, and robust for safe transportation by car to outlying areas.
