Amid growing interest in measures against global warming in recent years, heat pump water heaters that have a large effect of reducing CO2 emissions are rapidly coming into wide use. Fig. 2 shows the changes in the cumulative number of installed units of Eco Cute for household use. The number of units sold has rapidly increased to reach 3.57 million in late November 2012. Fig. 3 shows the changes in the cumulative number of installed units of heat pump water heaters for commercial use. Heat pump water heaters not only for household use but also for commercial use are coming into widespread use, and the cumulative number of installed units of heat pump water heaters for commercial use exceeded 17,000 at the end of FY2010.
