Mixergy secures £9.2 million investment to expand their home energy and heat storage technology

March 27, 2023

We are thrilled to announce that we have secured a £9.2 million investment to support a new R&D centre at our Oxfordshire headquarters, further develop our home energy and heat storage technology, and expand internationally.

This funding round will further accelerate our mission to cut heating bills, decarbonise homes and provide more flexibility to the grid.

Mixergy has a suite of IP around hot water heating, heat pump and home energy management technologies, using a patented top-down approach to heating that exploits thermal stratification to only heat what you need.

This, in a combination of sensing and control capabilities, transforms simple hot water tanks into smart heat batteries, which can connect to any energy source (heat pump, solar PV or gas/oil boiler).

With each system lasting 25 years+ (greater than 3x the lifetime of a battery), and all systems heat pump and PV ready, whatever pathway our energy system takes, Mixergy tanks will be on hand to help deliver the 95% reduction in CO2 in our homes, a critical step to achieving net zero by 2050.

“We’re thrilled with this investment and pleased to welcome our new investors, EDP Ventures and Nesta. EDP Ventures is one of the biggest energy providers in southern Europe and their arrival is a catalyst for Mixergy’s expansion across Portugal and Spain, where we see great product market fit alongside solar PV. Nesta brings considerable experience to this sector alongside an emphasis on social impact which complements our drive to address fuel poverty whilst reducing carbon emissions. I would like to thank our existing shareholders, OSE, IPG, Foresight, and Centrica who continue to back our mission, as well as our incredible team at Mixergy who are making this journey happen.”

Peter Armstrong, CEO of Mixergy

The Energy Savings Trust has verified that Mixergy can reduce gas consumption by as much as 20% whilst reducing costs by 40%. These figures can rise further through the intelligent use of renewable tariffs, which exploit the ever-growing surplus of wind and solar energy emerging across power grids worldwide.

In addition to reducing energy consumption, Mixergy’s top-down heating also heats usable hot water up to 10x faster than a conventional system, with the Mixergy app or simple gauge offering homeowners total control of their water heating.

This is why the Mixergy tank is the ‘no regrets’ purchase for homeowners, installers and developers.

New investors, new markets

This funding round brings in EDP Ventures and Nesta as new investors. In addition to supporting the R&D centre that will develop innovative integrated heat pump technologies, the new funds will be used to bring international expansion, starting with Portugal.

“We’re very excited to be joining Mixergy on their mission to improve energy efficiency at residential level and support the company’s growth plans. Distributed energy resources and decarbonization are two domains at the heart of what we do here at EDP Ventures, and Mixergy’s technology is fully aligned with both: a smart and connected hot water tank that acts as a home battery, providing faster water heating and harnessing solar power. As such, we look forward to supporting Mixergy in the future, with the rollout of its products across EDP’s markets.”

Luís Manuel, Managing Partner at EDP Ventures

“We are delighted to support the Mixergy team in the next phase of their growth journey. Nesta’s goal is to accelerate the decarbonisation of households and we see Mixergy as an exciting and critical solution that can help deliver this.”

Leo Chandler, Investment Manager at Nesta

EDP Ventures and Nesta are joining Mixergy’s existing shareholders, Oxford Science Enterprises (OSE)Kiko VenturesForesight WAE Technology and Centrica, who continue to back Mixergy as a market leader in home energy and heat storage technology.
