Midea won the Hot Water Innovation Prize for a split‑system heat‑pump water heater that separates the compressor from the storage tank, enabling installations in smaller homes and multifamily buildings. NEEA estimates it could save about $240 per household per year and reach over 2 million U.S. homes. Nationwide adoption of similar split systems could deliver approximately $5.6 billion in annual utility savings, avoid 35 billion kWh of electricity and cut about 14.3 million U.S. tons of CO2 annually. Midea receives $175,000 to further develop the product.
Midea’s Space‑Saving Split Heat‑Pump Water Heater Wins U.S. Innovation Prize — Could Cut Bills for Millions

Midea won the national Hot Water Innovation Prize for a split‑system heat‑pump water heater designed to fit smaller homes and multifamily buildings where conventional units are too bulky.
Why This Matters
Heat‑pump water heaters use far less electricity than traditional electric‑resistance tanks, but many existing models are large and difficult to place in apartments, manufactured homes and houses with small utility rooms. By separating the compressor from the storage tank, Midea’s split design gives installers more placement options and makes efficient water heating practical in tight spaces and retrofit projects.
Estimated Savings and Impact
The Northwest Energy Efficiency Alliance (NEEA) estimates the system could lower annual energy costs by about $240 per household on average and reach more than 2 million U.S. homes each year. NEEA’s analysis suggests broad replacement of small electric‑resistance heaters with such split heat‑pump models could deliver roughly $5.6 billion in annual utility‑bill savings nationwide, avoid about 35 billion kWh of electricity use annually and cut roughly 14.3 million U.S. tons (13 million metric tons) of CO2 emissions per year.
Prize Support and Commercialization
As the competition winner, Midea will receive $175,000 to continue product development. That funding is intended to accelerate commercialization and address retrofit challenges where confined layouts have previously made installations difficult.
Broader Market Context
Other manufacturers are also innovating to make efficient water heating easier to use. For example, Cala offers customizable smart heat‑pump water heaters that schedule heating times to match household needs and reduce waste, giving homeowners more control over energy use and costs.
Bottom Line
Midea’s split‑system approach could extend access to one of the most energy‑efficient home appliances to millions of households that were hard to serve before, enabling easier installations, lower energy bills and significant carbon‑emission reductions.
