Electric Electric Water Heater
EcoCute which is nice for you who are kind to the earth
We make good use of naturally occurring CO2 as refrigerant (※ 1) not Freon. Generally CO2 refrigerant is naturally occurring matter, and there are not the combustibility, the toxicity, too. Influence zero, global warming potential to the ozone layer are 1/1700 of Freon. Furthermore, we can boil hot water of 90 degrees Celsius by heat pump method (figure) because CO2 refrigerant is superior in ability for heating. It is energy saving effect in high efficiency in matching power of CO2 with electricity, and making hot water. Therefore compare electricity with conventional electric water heater; and only 1/3. Of course as for the electricity bill in 1/3.
Japan ratified the Kyoto Protocol in 1990 and promised 6% reduction of greenhouse gas for the world compared to 1990 by 2012. However, approximately 9% increase in 2007, too. 31.4% increase only for home section, too. Does 30% of domestic energy consumed know what is spent for boiling hot water supply that is hot water? Therefore country assumes 5,200,000 spread of EcoCute index for Kyoto Protocol accomplishment by 2010.

【EcoCute rate calculation method】
●Kyushu Electric Power: “Season light according to time” (except base rate)
●Consumption: When we assume 140kWh. (it is heated, and increase, thermal insulation does not consider.)
※※Our estimate (the annual mean). Hot water supply load converts 43 degrees Celsius conversion quantity of water of IBEC-L mode at water supply water temperature of applicable area and calculates. Electric bill uses number of light contract according to time or light contract rate according to time for season.
※There is change of electricity bill by consumption of hot water or season. ※Daytime rate unit price of light according to time, light according to time becomes more expensive than sub-quantity light contract for season.
