Solar water tanks are mostly used in thermal heating systems (SWHs) to serve as buffer tanks. With them, it becomes easy to expand the solar heating package at anywhere and anytime without using any expensive equipment. When there is bright sunshine, the heat energy absorbed by solar collectors will be transferred to the water present inside the solar water tanks for use later, most frequently in the cold evenings and nights. Many of these tanks include a heat exchanger to heat up water to a point so that it can be used for washing utensils, clothes and maintain personal hygiene. Additionally, they offer good insulation effect that would help retain the heat value for days.
The functional efficiency and capacity of solar water heating system demands an increased number of pipes to carry the heat trapped by solar collectors and addition of a solar water tank to keep the hot water inside for future use. The whole heating system is insulated effectively to reduce heat-loss. Water is then made to circulate through the collectors several times to bring a rise in the temperature. There are electric pumps to push water through the SWH, but it will add to the cost. Instead, thermosyphon mechanism can be used to make water flow through the pipes without the need of an expensive pump.
Thermosyphons work around the principle that hot water moves to the top, leaving cold water in the bottom. In passive solar heating systems, the solar water tanks are always placed above the collectors. When the water starts to heat up in the pipes, it keeps moving to the top section of the tank, making cold water to flow down into the pipes from the bottom area. The flow of water keeps on until the temperature of water in the tanks and the pipes become the same. There are also one-way valves to prevent hot water flowing back in another way especially when the temperature falls drastically in cold nights.
