PCM PRODUCTS

ALL YOUR HEATING & COOLING NEEDS 100 % FREE

By introducing eutectic products into a radiant heating system , it is possible to capture excess heating during daytime using conventional solar collectors such as vacuum collectors or PV Thermal collectors and store the free solar energy within the floor Phase Change Material thermal energy storage ( PCM-TES ). In return over-night , this stored energy acts as a radiant heating floor and keep the occupied space warm . As the heating can be provided without using any primary energy source , it offers an unparalleled environmentally friendly and cost-effective solution for both domestic and commercial heating applications . Furthermore , as PCM-TES has no moving parts it also offers a maintenance-free heating system .
ThinICE CONCEPT By simply adding 27 ° C ( 81 ° F ) ~ 34 ° C ( 93 ° F ) phase change material ( PCM ) encapsulated in sealed HDPE modules , one can increase the heat storage capacity of the floor screed by 50-fold .
As this material captures energy by melting and releasing it when it freezes using solar free energy it offers a cost-effective and environmentally friendly heating option . If required a small scale heat pump can be incorporated not only to top up this heating but also provide the hot water requirements and even the possibility of running this small heat pump from solar PV cells and maybe during off-peak hours one can provide a reliable and very low running cost system with a very attractive return on investment .
