TEPCO'S 'Eco Cute' the World's First CO2 Heat Pump Water Heater for Residential Use
 
Company Unveils the Results of the Development of an Environmentally Friendly Water Heater for the 21st Century at ENEX2001

Tokyo, Apr 19, 2001 - (JCN Newswire) - TEPCO have been undertaking the development of a CO2 heat pump water heater for residential use in conjunction with Denso Corporation and the Central Research Institute of Electric Power Industry since September 1998. A series of verification tests have been carried out to prove it can be put to practical use and the findings of the project will be unveiled at ENEX2001 (at Tokyo Big Site from February 7 to 9).

The new CO2 heat pump water heater, "Eco Cute" *1, will be put on the market by water heater manufacturers, and TEPCO will play an active role in the marketing and promotion of the product.

Eco Cute not only enables significant energy conservation in water heating (*2), which accounts for about 30 percent of household energy consumption, but also helps to prevent the destruction of the ozone layer and the emission of greenhouse gases. Its characteristics can be summarized as follows.

1. The heat pump system, in which a compressor generates heat energy by the resourceful intake of heat from surrounding air, produces three times as much heat energy as the electric energy used in this process. This is expected to save 30 % more energy in comparison to standard fossil fuel fired water heaters.

2. Atmospheric CO2, instead of conventional CFC gases, is used as a refrigerant and so will help prevent the destruction of the ozone layer and the emission of greenhouse gases. Although the typical heat pump water heaters only allow heating up to 65, the Eco Cute is capable of heating water to 90 without heater.

3. By utilizing electricity during the night which is 70% cheaper than daytime electricity, and combining a highly efficient head pump system, the running costs are very competitive. It is also safe, comfortable, clean and compatible with households where all kitchen and heating appliances are run on electricity.

4. The Eco Cute is also equipped with a fully automatic function, which can fill water in the bathtub, keep the water heated, and adjust water volume at the flick of just one switch. There is also a voice function, which 'speaks' to inform the bathtub is full.

5. The hot water tank is thin and compact, making installation in confined spaces easier, compared to storage type water heaters.

TEPCO will continue to conduct research and development which leads to environmental protection, and work on providing a price list and services that will help reduce the energy costs of its customers.

*1 Power companies and water heater manufacturers plan to carry this product under the name "Eco Cute" in Japan.

*2 Household energy demand amounts to about half of the final residential and commercial energy consumption, which is 14% of the entire energy demand. 30% of household energy consumption is for water heating purposes, more than 90% of which from fossil fuel fired water heaters.
