Frankfurt, 17 March 2025: For the first time, customers can now buy a super-compact heat battery that is compatible with Midea heat pumps and also works with solar PV and grid electricity to take advantage of off-peak tariffs. The heat battery eliminates the need for a traditional hot water cylinder with the R290 M thermal Arctic HT heat pump series.
UK company Sunamp, a world leader in thermal storage technologies, has developed new Optimino key technology that enables its Thermino xPlus heat battery to integrate seamlessly with the Midea R290 M thermal Arctic HT heat pump range. When paired together, they improve efficiency, save valuable space and enable all households to transition to net-zero heating.
The compatibility breakthrough means homeowners can enjoy all the benefits of a heat pump without requiring bulky hot water storage, opening up new possibilities for properties where space constraints have been a barrier to adoption.
Making the announcement today at ISH in Frankfurt, the world’s leading trade fair for HVAC + Water, Sunamp CEO Andrew Bissell encouraged OEM customers of Midea heat pumps to take advantage of the innovation: “With our Optimino technology, our heat battery is now fully compatible with Midea heat pumps from the R290 M thermal Arctic HT series, offering a streamlined, efficient solution for hot water storage. We invite OEM customers to reach out and explore how this can enhance their heat pump offerings leveraging Sunamp’s extensive patent portfolio and IP leadership.”
This advancement is expected to drive greater adoption of heat pump technology by making installation easier and improving overall system performance. As energy efficiency becomes a growing priority, the combination of Sunamp’s heat battery and Midea heat pumps represents a significant step forward for sustainable home heating solutions.
