SUNAMP: More energy in less space
Sunamp develops innovative thermal batteries designed to store energy efficiently in the form of heat. This compact and versatile technology helps improve system efficiency while making better use of energy from heat pumps, solar PV, the electricity grid and other energy sources.
At the heart of Sunamp technology is Plentigrade®, a high-performance phase change material (PCM) capable of absorbing, storing and releasing large amounts of thermal energy as it changes between solid and liquid states.
Thanks to its high energy density, Sunamp thermal batteries can store large amounts of energy in significantly less space than conventional water-based thermal storage systems.
A new way to store heat
Traditional heating systems generally store thermal energy by increasing the temperature of a large volume of water.
Sunamp instead uses the latent heat of its Plentigrade® phase change material. During charging, the material absorbs thermal energy and changes phase. When heat is required, the stored energy is released back into the system.
The result is a compact and highly efficient thermal storage solution with extremely low heat losses, allowing energy generation to be separated from the time at which that energy is actually required.
Why choose Sunamp?
Reduced footprint: The high energy density of Plentigrade® significantly reduces the space required for thermal energy storage compared with conventional water-based solutions.
Heat pump integration: Sunamp thermal batteries can be combined with heat pumps, allowing energy to be stored when the system is operating under favourable conditions and released when demand increases.
Optimised use of solar PV: Surplus electricity generated by a photovoltaic system can be converted into thermal energy and stored for later use, helping increase on-site self-consumption.
High energy efficiency: Very low heat losses help retain stored thermal energy until it is actually required.
Flexible installation: Their compact dimensions make Sunamp thermal batteries suitable for both new-build and retrofit projects, particularly where plant-room space is limited.
Modular and scalable: From domestic hot water to commercial and industrial applications, Sunamp technology can be configured according to the required thermal storage capacity.
From homes to industry: The Sunamp range provides solutions for a wide variety of applications.
Thermino
Thermino offers a compact alternative to conventional domestic hot water cylinders, with configurations designed to work with electricity, solar PV, boilers and heat pumps.
For commercial and industrial applications, Central Bank solutions provide modular, high-density thermal energy storage and can also be used for applications such as waste heat recovery or shifting heat generation to periods when energy is more readily available or cost-effective.
With Sunamp, thermal storage becomes an active part of the energy system: more compact, more flexible and ready to make better use of renewable energy.
