• Biomass Heating Systems
• Oil & Gas Boilers
• Solar Thermal & Solar PV

How Does Phase Change Work?

Phase Change Materials (PCM) absorb and release heat as they melt and solidify just like ice turning to water and back again. This process allows eStor to store and deliver heat with exceptional efficiency.

Key Benefits of Bio-PCM:

• High energy storage capacity
• Stable temperature regulation
• Reversible and repeatable performance
• Eco-friendly, non-toxic, and non-corrosive

Upgrade to eStor today and experience the future of hot water storage efficient, compact, and built for a greener world.
