At the beginning of February, the water heater in my home broke down and I had to replace it.
I have replaced my EcoCute, which was first installed in 2010.
It broke down suddenly without warning, so we didn’t have time to consider the manufacturer, model, etc. The contractor suggested the quickest possible installation, which was completed in five days.
(Example of EcoCute)
EcoCute has an image of being both environmentally and wallet-friendly, but I took the opportunity to find out a little more about it.
According to Wikipedia, the official name of EcoCute is “natural refrigerant heat pump water heater” and the name “EcoCute” is a registered trademark of Kansai Electric Power Company, a nickname used by Japanese power and water heater manufacturers. In April 2001, based on a basic patent from Denso and other companies, CORONA CORPORATION launched the world’s first EcoCute, and I was suddenly interested to learn that our client Denso was involved in its development.
Further investigation revealed that research technology aimed at developing car air-conditioners using carbon dioxide (CO2) as a natural refrigerant had caught the attention of researchers at the Central Research Institute of Electric Power Industry, who were studying next-generation hot-water supply systems, and members of a TEPCO research team who were looking for new product development, and they decided to launch a project called “Heat pump water heater using natural refrigerants” by three companies from different industries.

One of the notable advantages of EcoCute is that it is equipped with an emergency water intake tap, so that the water in the tank can be used as domestic water when the water supply is cut off due to a disaster.
Daikin’s official website states that a 370-litre hot water storage tank can provide a family of four with about three days’ worth of water for emergency use.

EcoCute is expected to become more and more popular as it reduces the environmental burden, lowers utility costs and helps to mitigate disasters.
By the way, did you know that ‘Kyuto in Japanese, Cute’ in EcoCute is taken from the word ‘Kyutou in Japanese, hot water supply’? I hadn’t noticed that at all! It’s a very good name♪ (cacao)
