EcoCute CO2 heat pump water heaters

[Thermatech]

For the last 7 years refrigerant C02 has been used for domestic air to water heat pumps for domestic hot water in Japan.
Major manufacturers like Hitachi, Daikin, Mitsubishi, Toshiba, Sanyo have been selling them by the 100,000 for years in Japan.
The Govenment in Japan provide yen incentive for purchase of this type of water heater.

As this is old technology in Japan we can expect this type of equipment to be available soon in Europe

Are there any service engineers in Japan who can provide some hands on technical experiance for us European engineers who have no Co2 heat pump experiance.:rolleyes:

For a small insite (Its in Japaneese!) have a look at this youtube.com/watch?v=ZIYwoHtrXN0 just put the 3 'w'' at the front! I'm stilll too new to post URL's!
This is for the latest Daikin version sold in Japan. The CO2 (R744) piping is all inside the outdoor unit meaning a plumber can install it as they do not need to touch the fridge side.

Hi Guys,

Sanyo have been selling these in Europe for 2 years but very little interest so far. If you want I can supply tech data and manuals for these Its very basic info but you may find it interesting.

We will be improving our range early next year and will have 6 model sizes with kits to connect to any water tank so this should improve the systems appeal in the market place.

Gat back to me if I can help.

Techguy, the other part of my business is central heating and hot water, so naturally I'd be interested too.. Trianco do something similar but it seems a bit old hat running on R407a. It would be nice to be able to offer a decent quality alternative to solar panels
