How does an AC water Heater work?

"The hot gas goes from the compresser through a coil in the water heater, then back to the condensing unit and expansion valve.

I have oodles of free hot water. Whats more, the aircon seems to run more efficiently as it is now water cooled so probably there will be a reduction in power consumption.

Such a simple concept. Think of all that wasted energy over the nearly 40 years I have been using air conditioners." .....MW - 2/4/2010

If you use a tank of hot water every day this will cost you about 2 million rupiah a year.
