phase change materials

Solar thermal and photovoltaic thermal systems can use phase change materials to store the excess thermal energy generated in the summer to be used during winter.

Suitable for domestic situations where space is at a premium and commercial businesses with high hot water usage like swimming pools.

about phase change materials

PCM tanks

Phase change materials work like a hand warmer - you apply heat and the energy being applied is absorbed into the material. At a certain temperature the material changes from one state to another - from a solid to liquid - once it changes it holds on to that heat until its needed.

advantages of phase change materials

  • They have no moving parts
  • Long life expectancy
  • Almost zero maintenance
  • Space saving - up to four times smaller than other thermal storage systems
  • A fit and forget solution!
