Warmstone is our patented solid storage material that is made from a combination of recycled and natural materials.
We use cheap nighttime electricity to heat the solid core of the Caldera. We then use the stored heat to provide a supply of hot water and heating to your home during the day when you need it.
If you live in a house that uses heating oil or LPG, has solid walls (built pre-1930) and normal radiators, then you will almost certainly be better off with a heat battery.
