About Mixergy

Mixergy does things differently

Mixergy has become a market leader in hot water tank innovation by doing things differently. We are re-thinking how hot water is done, using technology to find cost-effective and convenient solutions which help people live more sustainably.

We do this by giving our customers the ability to take control of their energy consumption, reduce their energy bills, and optimise the use of renewable energy.

Through technology, we are unlocking new opportunities for customers to have greater choice and flexibility in how they meet their hot water needs.

Where we come from

The Mixergy tank was conceived in the Department of Engineering Science at Oxford University by Pete Armstrong and Ren Kang who joined forces to compete at the 2014 Climate-KIC accelerator competition.

The vision was to develop an ever-expanding network of intelligent hot water tanks which could provide flexibility to the grid, enabling more renewable energy, and supporting the clean energy transition. Pete and Ren went on to win the 100,000 Euro prize along with accelerator support to set up Mixergy.
