"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."

 The Wika Air Conditioner Water Heater connects into your existing standard air conditioner.
It uses the heat your air conditioner extracts from your house to heat your water instead of throwing it away to the atmosphere.
- Available in 75 and 100 litre capacity.
- Requires no power to operate.
- Available with 500 watt electric booster element if required.
- 2 hours of standard operation of your AC heats your water.
- The heater costs only a little more than a standard electric hot water heater.
- Water tank is stainless steel with polyurethane insulation.
- Pays for itself in 2.5 years.
- Reduces loads on your electrical circuits.
A standard electric water heater takes about 4.2 kilowatthours of electricity to heat a 100 litre tank of water from 24 degrees centigrade to 60 degrees centigrade. A kilowatthour of electricity currently costs 1,340 Rupiah.
If you use a tank of hot water every day this will cost you about 2 million rupiah a year. This means the air conditioner water heater will pay for itself in about 2.5 to 3 years - a considerably faster pay back than a solar hot water system which will take from 6 to 12 years to pay for itself depending on the model you buy.
