Technology

Warmstone is a patented breakthrough in thermal storage that uses a combination of recycled and natural materials.

Warmstone is non-flammable, non-toxic and safe to use in your home.

Warmstone supports the circular economy as it is 100% recyclable at end of life.

Our Heat Battery consists of a block of Warmstone that is heated by electrical elements that are similar to those used in your oven or kettle. Heat is discharged via a heat exchanger to produce hot water.

Using highly efficient insulation results in over 90% of the energy being recoverable as heat for your home.
