FAQ PCM Batteries
What is a PCM thermal battery and how is it different from a water buffer tank?
A PCM battery stores latent heat: during the phase change, it maintains the melting point temperature for longer, providing greater stability and often a smaller footprint for the same amount of useful energy.
How are they different from traditional water storage?
For the same use case, PCM helps achieve a more stable temperature and a more usable "useful" heat content. Furthermore, the storage can be more compact and integrated into smaller technical spaces.
How does a PCM battery work (charging and discharging)?
The core of the technology lies in the use of a phase change material (PCM) contained within an insulated tank, which houses a high-performance heat exchanger. Unlike traditional inertial water-only systems, the thermal battery exploits the principle of latent heat: during the "charging" phase, the PCM absorbs thermal energy from the water passing through the exchanger and melts at a constant temperature (phase change point), storing heat. During the "discharging" phase, the material releases the accumulated heat, returning to a solid state. Thanks to the storage capacity and high efficiency of the internal exchanger, the system guarantees the instantaneous production of domestic hot water with high thermal output.
What are load shifting and peak shaving used for in a thermal system?
Load shifting moves energy use to more convenient time slots; peak shaving reduces demand peaks that degrade efficiency (e.g., drop in COP).
Is the PCM battery compatible with heat pumps and solar systems?
Yes: it can store energy when there is a surplus and release it when needed, improving continuity and load management.
What are the most suitable applications?
Domestic hot water, space heating, large buildings, integration into industrial processes, and district heating systems (whenever thermal flexibility is needed).
Is it safe? Are there any moving parts?
It is a static system: no moving parts and materials designed to be safe for both health and the environment.
What maintenance does it require?
Limited: the logic is "static" and monitoring can also be done remotely (depending on the configuration).
What temperatures can a PCM battery cover?
It depends on the PCM used. i-TES batteries typically operate within a temperature range of 15 to 80°C.
