subject: You Dont Have To Blow Hot And Cold To Get Hot Water At The Turn Of A Tap [print this page] Water is a basic human requirement for civilized existence. Depending on which kind of climate you live in you would normally need a hot and cold water dispenser round the year. Solar power is being used in remote areas to power water pumps to get a fresh water supply to them from wells or other sources. However, you too can harness solar power as long as you reside or operate in an area which has plentiful sunshine and can use the roof or your backyard to set up the solar panels. Whether it is for domestic purposes or for use in a health facility or even hotel, the common factor is the need for continuous flow of hot and cold water from the taps. In some places a non-pressurized water heater is used to ensure the continuous supply of hot water.
The Atlantis solar water heater relies on the natural circulation of water between the collector and the tank or heat exchanger. This means that you must have a non pressure solar collector for the hot water to flow into and be stored. In this type of installation, the tank must be located above the collector. As the suns rays hit the evacuated solar collector tubes the temperature of the water in the tubes rise to certain heat levels, lowering the density of the water. As water in the vacuum tubes is heated it becomes lighter and naturally rises into the tank. Meanwhile, cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. The air vent valve on the top of the storage cylinder and the over flow pipe in the bottom of the thermal insulated tank establishes interface with the air.
While you are on a power saving spree you could also look at options for cooling like a portable evaporative cooler. It can operate with an axial fan or incorporate a 2-speed blower fan that can blow air at high velocities with minimal noise. Ideally the cooler should have a storage capacity of up to 5 gallons of water. Those which work on 3.5 Amps can save a lot of energy but can still efficiently cool a 700 sq feet area. The louvers of this kind of cooler can also be adjusted to control air distribution. However, it is inadvisable to try and run it on a modified sine wave inverter which produces fast, cheap power. It is called a modified sine wave because its not a perfect sine wave: it rests at zero for a while as it fluctuates between positive and negative. Some people do think it is a good option for keeping rugged machinery running during outages, but remember that your cooler is not a rugged piece of machinery.
