Heat battery company Caldera has teamed up with myenergi to develop a customised control system.
This will utilise a version of myenergi’s eddi controller to intelligently manage the energy supply into Caldera’s Warmstone heat battery.
Warmstone is designed to charge using cheap, green, off-peak electricity, store it and then release it as required to power heating and hot water.
“Our heat battery can hold 100kWh of energy – more than enough heat and hot water for the average four-bedroom home,” said Caldera chief executive James Macnaghten. “This stored heat energy is then delivered on demand to the water circuit that runs through your home, to heat radiators and deliver hot water, just like a traditional oil or gas boiler.”
myenergi has a suite of eco-smart home technologies such as the zappi electric vehicle charger and eddi, a system that controls how self-generated green electricity is used in the home.
As the UK’s electricity mix becomes increasingly renewable, there is a growing opportunity for households to take advantage of cheaper electricity through flexible tariffs when there is an excess of clean generation.
“Our family of intelligent controllers analyse all of the energy demands in your home – from your cooker to your EV and heat battery – to ensure you are charging at the optimum time,” said Jordan Brompton, co-founder and chief marketing officer at myenergi.
The two companies are trialling the combination of the eddi controller and the Warmstone on 12 units being installed in pilot homes in the south of England this year, with hopes to commercially roll this out in 2022.
Current± caught up with Caldera’s Macnaghten recently to discuss how the heat battery compares to the heat pump, and what’s next for the technology.
