Sunamp

Sunamp designs and manufactures compact thermal energy storage solutions that make homes, buildings, and industries more energy-efficient and sustainable while reducing carbon emissions.

Its product lineup includes Thermino for domestic hot water with heat pump and solar PV compatibility, Central Bank for commercial and industrial heating, and Permafrost for cooling and refrigeration. The solutions are significantly more energy-dense and space-saving than conventional hot water cylinders, integrating seamlessly with renewable energy sources and grid electricity.
