PCM Heat Batteries
Phase change material (PCM) is a substance that, by melting and freezing at a certain temperature, can store and release a large amount of heat at that temperature.
Ice (phase change at 0°C) Hand warmer (melts at 58°C)
Sensible Heat Versus Latent Heat, example with Sodium Acetate

Sunamp Heat Batteries
• PCM temperature can be adapted to service, region, economics;
• Heat Batteries are used to:
1. Maximise COP of heat pump
2. Maximise self-consumption of renewables
3. Maximise comfort to user
4. Minimise energy bills
5. Minimise installation and maintainance cost
6. Install storage where no water tank would fit
