Mixergy Ltd, a University of Oxford spin-out, has developed an internet-connected, smart hot water tank that gives users greater control and oversight over their water heating systems. Traditional water cylinders heat up all the water within, or none, like a giant kettle. Mixergy’s tanks use thermal stratification and an innovative heating arrangement to heat the water from top down. That way, consumers can selectively heat different volumes of water and save 5% to 20% on their hot water bills.
Mixergy’s top-up technology enables hot water to be delivered up to five times faster than conventional cylinders. In addition, by having internet connectivity and an artificial intelligence algorithm running on the Mixergy cloud platform, customers can better utilise time-of-use tariffs and use the unit’s app as a smart remote control.
Ren Kang co-founded Mixergy in 2014 and is its Head of Research. He joined the SME Leaders programme in 2021 and is looking forward to it helping him “transition from being the company’s technical director to being its industrial leader. By better-planning Mixergy’s product development, I will be able to prepare it for future energy challenges and opportunities.”
Since its inception, the Mixergy team has grown to 21 staff and built strong relationships with British Gas, a major installer of tanks. In 2020, Mixergy raised £3.6 million in a Series A funding round. This has allowed Mixergy to gain further commercial traction in UK and European markets.
