Smart and efficient unit
The operational costs can be up to 75% less than that of an electric water heater, and can
be installed in locations which are unsuitable for solar hot water heating.
2.2 Characteristics
Easy to operate
Featuring an easy to use timer for both start and stop operations, with a controller to set the
desired water temperature.
Safe and environmentally friendly
Produces no harmful gases along with no open flame, making the unit safe to work with
when installing.

it goes through the compressor.
On the discharge side of the compressor, the now hot and highly pressurized vapor
is cooled down through the heat exchange with the water in the tank until it
condenses into a high pressure, moderate temperature liquid.
Then the pressure of the liqiud refrigerant drops as it passes throttling device.
Finally, refrigerant absorbs heat from the surrounding air and evaporates into
vapor with low temperature and low pressure and then it goes into compressor
again.
The cooled surrounding air could be blew to the rooms which needs fresh cooled air.
