Eco Cute: an emerging technology in the US water heating market

By team, Oct 20, 2011, 12:22 1 minute reading

A study recently released by the American Council for an Energy-Efficient Economy (ACEEE) examines emerging energy-efficient water heating technologies and practices as of 2011 that can save around $ 18 billion in energy consumption. The Japanese “Eco Cute” heat pump water heater is considered in the study as one of the potential applications.

According to the study, the new water heating technologies that are evaluated can result in approximately 37% energy savings in residential and commercial buildings by 2025 as water heating represents the second largest share in energy consumption after space heating and cooling. The “Eco Cute” heat pump using CO2 as working fluid is recognised by ACEEE in this study as an alternative technology that could considerably contribute to great product variability in a relatively small marketplace.

The study also estimates that nearly half of the evaluated technologies are cost effective with today’s product, installation and energy prices. By 2025, almost 70% of these technologies become cost effective.

Emerging technologies

The study reviews and examines several groups of products and services that vary not only by degree of market adoption, but also by the amount of “push” given to them by leading market transformation actors.

  • Residential point-of-use electric water heaters
  • Energy Star moderate climate heat pump water heaters
  • Add-on heat pump water heaters
  • Residential condensing gas tankless water
  • Solar assisted water heater
  • Condensing gas ‘hybrid’
  • Non-condensing gas ‘hybrid’
  • Energy Star high efficiency gas storage
  • Condensing residential tank gas water heaters
  • Advanced ground source heat pump approaches
  • Drain water heat recovery
  • Single-family demand-activated recirculation systems
  • Commercial point-of-use applications
  • Multifamily best practices
