Modern thermal stores known as "heat batteries" use a high performance phase change material to produce hot water that flows quickly. consistently, securely, and effectively. heat batteries will fit in most houses and save on crucial storage space because of their size, which is up to four times smaller than a comparable hot water cylinder.

They don't need to be maintained every year and are also simple to install and more environmentally friendly.

Super-compact thermal batteries
How it works
Storing heat and releasing it on demand

Optimising renewables
Thermal batteries support the electrification of heat.
They work with heat pumps, wind and solar, grid and microgrid electricity, waste heat, combined heat and power (CHP) and boilers.
And store 4 to 10 times more energy than conventional materials.

Sustained with Plentigrad
Plentigrade technology stores energy in our high-performance phase change materials and releases it to give hot water, heating or cooling on demand.
Long lifespan with best-in-class reliability rating.

Wide temperature range
Plentigrade discharges at a consistent, controlled temperature.
Reliably, safely and efficiently.
This means thermal batteries can be used to freeze (-30°C), refrigerate (5°C) or warm (58°C), and even sterilise (118°C) in many different settings.

Making homes, buildings and industry more energy efficient and sustainable
Combining low-cost materials, exceptional long-life and recyclability, our energy-dense batteries deliver a low-carbon solution for freezing, cooling, heating, steam, and hot water.
