Solar Hot Water

Solar Hot Water

By Yudha Urawa


Solar Hot Water is the H2O heated using energy from sun that is Solar Energy. The solar heating systems is generally used to heat water for home, business and industrial usage. Solar hot water systems are storage systems that can provide up to 90% of your hot water for free. Solar heating systems is composed of solar thermal collectors and a fluid system to move the heat from the collector. The system have tank for heat storage. To heat water using sun's energy, a collector is secured on wall facing the sun. The most common solar water heating systems are active systems. It is basically used in residential solar water heating applications. Solar hot water heating systems are a great way to effectively conserve energy and reduce your energy bill.

Solar water heaters can be used in any climate. The fuel used to run a solar heater is sunshine. A solar water heater can reduce your water heating bill by fifty to eighty percent. Aside from reducing your energy bill right now, a solar heating system will protect you from future energy price increases. Using solar power to heat your water will significantly reduce your carbon footprint. Solar heaters can be installed in combination with backup systems.

There are two thoughts when it comes to a solar hot water heater, depending on the location your hoping to put the hot water, solar panels might not be required. Nevertheless, to provide hot water through your entire home a solar hot water heater must be connected to an adequate number of solar panels to charge your batteries once the hot water usage is completed.

Typically in a solar hot water heater the heat will transfer the water into pipes or other types of storage systems then it is exposed it to sunlight, heating the water contained in the pipes. In a solar hot water heater the storage tank needs to be very well insulated to keep the water's heat level elevated.

A solar heating system is composed of solar thermal collectors that move the heat to its point of usage and a reservoir or tank for heat storage. The system may be used to heat domestic hot water, swimming pool water or for space heating. The system pumps cold water to a collector to be heated. The heated water flows back to a collection tank.

Essentially, solar water heating systems consist of a water storage tank and its solar collectors. The solar collectors are used to collect solar energy (which heats water), and the tanks store the heated water. 75% of the energy consumption of the average home is for hot water and heating. The most economical and effective way of using solar power is through the use of solar heating, and solar hot water heaters. Many passive systems depend on the water temperature to move water to the storage tank as cold water sinks to the bottom and hot water ends up rising to the top.
