Sunamp is a UK-based thermal energy storage technology company. Its core product is a “heat battery” based on Plentigrade® phase change material. It is not a traditional cloud service or software platform, but a hardware-based energy solution for buildings and industrial use cases, designed to store heat or cooling in a smaller footprint for domestic hot water, space heating, cooling, waste heat recovery, and load shifting.
For residential users, the Thermino series is positioned as a replacement for traditional hot water cylinders. It can be charged by the grid, air-source or ground-source heat pumps, boilers, and solar PV, delivering hot water on demand while significantly saving indoor space. For commercial and industrial scenarios, Central Bank Mini can store thermal energy from boilers, heat pumps, solar PV, wind power, or industrial waste heat, and use it for hot water, low-temperature process heat, cleaning, and peak-load reduction. Permafrost Mini is aimed at low-temperature refrigeration, cold chain, district cooling, and industrial cooling. The official website emphasizes that the products can be connected in modular series or parallel configurations, making them scalable from single homes to multi-building campuses, food and beverage plants, and data centers.
The official website does not publish standard pricing and does not offer an online purchase flow. The Permafrost Mini page says customers need to contact Sunamp directly to place an order; residential products rely more on installers, stockists, and project channels. Since capacity, heat source, heat exchangers, piping, installation, and local compliance all affect the final setup, actual costs should be evaluated on a project-by-project basis.
The main advantage is its clear technical approach: phase change materials provide higher energy density, allowing the unit to be much smaller than a traditional hot water tank. Heat loss is relatively low, and the system can be combined with heat pumps, solar PV, off-peak electricity tariffs, and waste heat recovery, helping reduce carbon emissions and energy consumption. The website also provides case studies such as UK high-rise social housing retrofits and waste heat recovery at a factory in Japan. The downside is that it depends heavily on engineering design, installation, and after-sales support, so it is not suitable for self-deployment by end users. Pricing, lead times, and the transparency of regional service networks are also limited, especially in markets outside the UK where further confirmation is needed.
Sunamp is best suited to public housing owners, developers, building services consultants, commercial building operators, industrial companies, and food and beverage manufacturers. If the goal is to “fit a heat pump into a space-constrained home,” “reduce the floor space taken up by hot water tanks,” or “use waste heat to cut gas consumption,” Sunamp is worth considering in the technical selection process.
The official website is directly accessible and provides a China regional entry point. Crawled content also mentions UK-China research projects and an ORC thermal energy storage project in China. However, information on local sales, certification, installation, and after-sales support in China is limited. Before purchasing, buyers should confirm regional agents, project delivery capabilities, and the applicable warranty scope.
