Caldera has secured a £470k grant from the Department of Business Energy & Industrial Strategy (BEIS)

We are delighted to have been chosen by the Energy Entrepreneurs Fund, who are funding the rollout of Warmstone heat batteries to 12 pilot homes across the south of England.

Our zero-carbon heat battery has been purposely designed to operate just like a boiler so there is no need for expensive retrofits. Because of this we are already taking a significant number of pre-orders from homeowners across the country who are keen to decarbonise their homes and get off oil and gas, yet are unable to make the economics of alternative technologies such as heat pumps work for them.
