Extended description
Sunamp is a Scottish company that makes compact thermal batteries using phase-change materials. Its heat batteries store energy as latent heat and release it on demand for hot water and space heating, offering much higher energy density than conventional hot-water tanks. Paired with heat pumps, solar or off-peak electricity, they can shift demand away from peak hours and help buildings use more renewable energy while saving space.
